    Preparation Method
    In the preparation of polyurethane rigid foam flame retardant, isocyanate and polyol are first used as main materials, supplemented by flame retardant components, such as organophosphorus, halogen-free compounds, etc., and several foaming agents, catalysts and stabilizers are also used. First, the polyol and flame retardant are precisely mixed, and the foaming agent is slowly added to make it uniform. Then the isocyanate is slowly dripped in, and then a catalyst is added. Addition polymerization occurs in an instant to form a polyurethane skeleton, and the foam gradually rises. The catalyst is mostly used in the genus of tertiary amines and tin salts, which prompts the rapid reaction of isocyanate and hydroxyl groups to strengthen the foaming rate and control the cell structure. During the reaction process, the flame retardant components penetrate into the pores and are evenly distributed, effectively blocking heat conduction The final foam is dense and solid, with outstanding flame retardancy, suitable for construction, electronics and many other fields.
    Chemical Reactions & Modifications
    Rigid foam, brittle in nature, afraid of fire. Its structure is mostly closed-cell, and the polymer chain is refined and difficult to self-extinguish. To enhance its fire resistance, chemical reactions and modifications are required. Often doped with elements such as phosphorus and nitrogen, or copolyphosphonates, can block flame vines and inhibit thermal decomposition. The reason is that when the foam decomposes, phosphoric acid is formed into carbon, or non-flammable gases are precipitated to isolate heat sources and oxygen. Or block copolymerization, grafting reaction, and new groups are introduced to make the molecular chains more closely cross-linked, and the thermal stability and fire insulation are increased. There are brominated flame retardants, but the toxicity of smoke is still a concern, so choose carefully. Nowadays, the method of synthetic modification is gradually becoming green and environmentally friendly, taking into account both performance and safety, making rigid foam widely used in the field of fire protection.

    What are the main flame retardant properties of Rigid Foam Flame Retardant?
    Rigid Foam Flame Retardant is also the flame retardant of the foam. Its property is strong, and it has good insulation, so it is used in construction, home, and transportation areas. However, the foam is flammable, quick-burning and toxic in case of fire, which is important for personal safety, so it needs to be flame retardant to increase its safety. The main flame retardant properties are as follows:
    One is the flame retardant rate. The flame retardant is inserted into the foam material, which is like a barrier, so that the material is exposed to the fire source and does not cause rapid ignition. Its production or non-flammability, or absorption decomposition and inert release, dilute and flammable flame, so that the burning rate is reduced.
    Both, inhibit. Some flame retardants can be released in the combustion process, such as bromine, phosphorus or flame retardants, more than in the combustion process, so that black and harmful substances are less, to ensure the safety of evacuation, and to reduce the generation of carbon monoxide, cyanide and other dangerous substances.
    Three, carbonization is generated. Some flame retardants can promote the formation of dense carbon at high temperatures, which is coated on the surface of the material to prevent the further invasion of oxygen, so that the unburned material is not delayed, and the integrity of the material is maintained, and the spread of the fire is delayed.
    Four, the chemical effect is stopped. The elements in the flame retardant can decompose and generate active free radicals, which can stop or inhibit the active molecules in the combustion reaction, so that the flame can be maintained, that is, the flame retardant process on the molecular surface.
    Five of them are compatible with various polymers and have both flame retardant and mechanical properties, so they are highly recommended. The guarantee requirements are high, and the new type of flame retardant has also been widely used, which is also safe for the human environment.
    Of course, Rigid Foam Flame Retardant has multiple effects such as flame retardant, poison suppression, carbon promotion, and combustion in the chemical industry. It makes the foam safer in various applications and can be an indispensable part of modern engineering materials.
    Where can Rigid Foam Flame Retardant be applied?
    Rigid Foam Flame Retardant is a flame retardant material of solid foam. Its material is light, has good thermal insulation, and has the characteristics of flame resistance. Since its invention, it has been widely used in many fields to prevent fire and ensure peace.
    Palace houses, building buildings and castles, afraid of fire invasion, often use this material to interlayer between walls and ceilings. It can not only insulate heat, but also prevent fire from spreading. Factory warehouses, confidential heavy land, especially fire protection, often apply flame retardant foam at the partition door panels to ensure safety. Modern metropolis, with many buildings, strict fire regulations, flame retardant foam is widely distributed in elevator shafts and ventilation ducts, flame retardant and smoke-proof, protecting people's safety. Rail cars, automobiles, ships, aviation and other transportation fields, are airtight and narrow, especially for prevention of disasters. It is widely used between the inner cabin panels, ceilings, and seats, which is not only light and weight-reducing, but also to reduce the risk of fire. Household appliances, cold box air conditioners, water heaters, and various household appliances also rely on this material to ensure the safety of the residence.
    Petrochemical, flammable and explosive, pipelines and storage tanks of plant installations must be equipped with flame retardant foam for fire prevention. Information room, old and new cables are staggered. In case of fire, this material is often installed to protect the line from burning. Theaters, exhibition halls, public halls, and public gathering places are equipped with flame retardant equipment for their decoration ceilings and baffles to keep them safe. New energy vehicles, energy storage power stations, lithium batteries accumulate, and fire risks are frequent. Therefore, solid flame retardant foam is installed in various departments to prevent problems before they occur.
    Overall, Rigid Foam Flame Retardant is widely used in buildings, transportation, household, industry, energy, public venues and many other fields due to its lightweight, high-strength, heat-resistant, and flame-resistant characteristics. Not only does it ensure the safety of utensils, but it also protects the people from fire disasters. It has made great contributions to the contemporary world.
    What is the environmental performance of Rigid Foam Flame Retardant?
    Rigid Foam Flame Retardant is a flame retardant foam product used in today's building materials and industrial fields. As the world knows, thermal insulation and fire protection are important for buildings, but environmental protection performance cannot be ignored. Looking at its production method, most of them are polymer-based, supplemented by flame retardants. Commonly used flame retardants are halogen, organophosphorus, aluminum magnesium hydroxide and halogen-free environmentally friendly new materials. From the perspective of environmental protection, its performance can be divided into advantages and disadvantages, and cannot be generalized.
    Halogen flame retardant has good flame retardant effect, but it is easy to release toxic smoke and long-term pollution when burned, which is harmful to humans, animals and ecology. Waste is difficult to degrade, and it will accumulate harm for a long time. European countries banned it and advocated halogen-free substitution. As for organic phosphorus, although it has been partially improved, it also has potential environmental risks. If aluminum magnesium hydroxide or halogen-free environmentally friendly flame retardants are used, the precipitation of harmful substances can be greatly reduced, and the residue after combustion is easy to deal with, which is more environmentally friendly.
    However, there are many links in the production of foaming materials from self-made to waste. If the emission of harmful substances such as VOCs can be controlled during production, and renewable resources can be used, it can increase environmental benefits. If it is not easy to decompose and release toxic particles during use, it is particularly safe. If the waste treatment can be recycled or safely incinerated without harming soil and water bodies, it will be worry-free. If the additives are used indiscriminately or the technology is not refined, it is dangerous to poison all things.
    Looking at today's green building standards, it has clearly standardized material environmental protection indicators and advocated a full life cycle perspective. Rigid Foam Flame Retardant materials, if they use new high-efficiency halogen-free flame retardants, cooperate with green preparation processes, and strengthen back-end recycling and degradation, can conform to the purpose of ecological civilization.
    Overall, the environmental performance of Rigid Foam Flame Retardant is closely related to the flame retardant technology used, raw material sources, production processes and waste management. If it can be removed from its harm and preserved for good use, it can take into account safety and environmental protection, and become an excellent material advocated by the times. On the contrary, if you ignore the responsibility of environmental protection, you will be evaded and eliminated. The way of environmental protection is to start with caution and end with caution.
    How to use Rigid Foam Flame Retardant?
    Rigid Foam Flame Retardant is also a rigid foam flame retardant. It is mainly used to improve the flame retardant properties of foam materials and is widely used in construction, furniture, transportation and other fields. The method of use must be carefully followed in accordance with regulations to obtain its maximum effect and ensure safety. The method is as follows:
    1. Prepare utensils. Clean the utensils and tools required for mixing and spraying in advance, and do not let dust impurities mix in, so as not to affect the ratio and reaction. When using, it is appropriate to wear protective equipment such as gloves and masks to protect the body.
    2. Proportion. According to the instructions provided by the factory, take an appropriate amount of Rigid Foam Flame Retardant and mix it in proportion with the main foam raw materials (such as polyurethane prepolymer, foaming agent, etc.). The weighing must be fine, and the mixing must be uniform. If the proportion is not correct, the flame retardant performance will be poor, and the foam structure may be loose or fragile.
    3. Stir with heat. Some formulas need to be heated to make the flame retardant blend more evenly with the raw materials, and some should not be mixed too fast to prevent excessive bubbles. Stirring is expensive to be uniform and moderate, and do not allow the precipitation to remain at the bottom.
    4. Shape and form. After the mixture is completed, quickly pour it into the mold or spray it directly on the desired substrate. After pouring, it is advisable to absorb vibration and not suddenly cool, so as not to affect the density and integrity of the foam forming.
    Five, curing and maintenance. After the foam is formed, it is placed in a ventilated and cool place and cured naturally. The length of time depends on the formula and environment. Do not move it arbitrarily during the initial solidification period. After it is completely consolidated, it can be transported and used.
    Six, safe disposal. After use, residual liquids and waste utensils must be properly cleaned up in accordance with the management of hazardous chemicals. Do not pour it at will to prevent pollution. If it accidentally stains the skin, it should be rinsed with water in time.
    In short, the use of Rigid Foam Flame Retardant is expensive for accurate measurement, rigorous mixing, and implementation in accordance with the process sequence. Then the flame retardant performance of the foam can be greatly improved, with both safety and durability, which can benefit all kinds of applications such as human settlements, industry and commerce. However, it is also necessary to carefully guard against the risks of operation to ensure safety.
    What are the storage and shipping requirements for Rigid Foam Flame Retardant?
    Rigid Foam Flame Retardant is one of the commonly used flame retardant materials in modern construction and industry. It is flammable and chemically active, so it should be especially cautious in storage and transportation to avoid disasters and damage to life and property. Now on its storage and transportation methods, such as left:
    Choose a place for storage. It should be placed in a cool, ventilated and dry place, strictly protected from sun and rain, and away from fire and heat sources. Its storage should be kept away from flammable, explosive and corrosive substances, and should be managed by special personnel to prevent misplacement. The temperature in the warehouse should be at room temperature, not high temperature and high humidity. Storage containers should be airtight and leak-free, and should not be damaged by moisture. Stacking should be neat and stable to avoid heavy pressure, bumping and strong extrusion. The entrance and exit of the warehouse area are unobstructed, warning signs are hung, and fire-fighting equipment is prepared for emergencies.
    The second is safe transportation. Special vehicles are dedicated, and the vehicles are clean and dry. It is strictly forbidden to ship with other dangerous materials in the same vehicle. During the consignment process, drops, vibrations and violent collisions should be prevented, and inverted subversion should not be done. Loading and unloading operations must be handled with care. Operators should have professional training and wear protective equipment. During transportation, they should not be near the high temperature of the fire to avoid sunlight exposure. In long-distance transportation, it is especially necessary to regularly check the packaging status of the goods to ensure that there is no leakage in the seal.
    The third is safety responsibility. Managers should often practice emergency plans, regularly check the hidden safety hazards of the warehouse, find any abnormalities, and rectify immediately. Incoming and outgoing records are detailed, and responsibility is placed on people. In case of fire, leakage and other dangerous situations, sand should be covered and isolated as soon as possible, and do not use water blindly to avoid severe reactions and disasters.
    The fourth day of regulatory compliance. During the whole process of storage and transportation, it is necessary to follow national and local safety regulations, strictly abide by environmental protection regulations, and prevent environmental pollution. The packaging label is clear, and the warning statement is eye-catching, so that the handler and the applicator can know the danger at a glance.
