Flame Retardant for Flexible PU Foam

Inflammation inhibitors used in flexible polyurethane foam can be traced back to the middle of the twentieth century. At the time of industrial take-off, polyurethane foam was widely used in furniture, automobiles and construction fields, but it was easy to burn in case of fire, and hidden worries gradually emerged. Scientists then explored the way of flame retardancy. At first, halogen flame retardants were used as flame retardants. Although the effect was fast, there was a risk of volatilization and toxicity, and the environment was damaged. Then new materials such as organic phosphorus and inorganic hydroxide came out one after another, but each had its own advantages and disadvantages. In recent years, with the increasingly strict environmental protection regulations, human-friendly green halogen-free flame retardants have gradually gained popularity. Technology is more advanced, particle size is refined, dispersion is good, and both flame retardancy and safety are taken into account. So far, the evolution of inflammatory inhibitors has not stopped, and human beings have coalesced their wisdom to protect life and the environment, complementing each other and innovating.

Flame Retardant for Flexible PU Foam is a flame retardant material specially designed for polyurethane soft foam. It is pure in quality and melts between the foams, giving the flexible foam the characteristics of flame retardancy. In case of fire, it releases flame retardant factors, which can inhibit the spread of flame retardant potential, slow down the combustion speed, and reduce the release of harmful smoke and toxicity. Its process is simple, easy to mix, does not damage the essence of flexibility, and does not damage the lightness and elasticity of foam. Widely used in furniture, bedding, automotive interiors, building cushions and many other fields. It is safe and environmentally friendly, self-compliant with regulations, and takes into account performance and health. Adapt to the needs of various applications and help products improve their fire rating. Therefore, flame retardant in the micro, solid in the invisible, it is a necessary supplement for modern polyurethane soft foam.

This flame retardant is a powder with a white color and slightly hygroscopic properties. It is soluble in water but insoluble in oil, and has not been dissolved in ethanol. When exposed to high temperature, it gradually releases decomposition products. The properties are stable at room temperature, and when exposed to acid and alkali, it can generate chemical reactions, or release gas, or generate precipitation. Mixed with polyurethane soft bubbles, it can be evenly distributed in the system without changing the color of the matrix, and slightly increases the density of the foam. Its ignition point is high, and the thermal decomposition temperature is much higher than normal. When heated, a protective layer can be formed on the surface of the foam to block oxygen and reduce the generation of flammable gases. Non-corrosive, no risk of erosion to metals, rubber and general non-metals. The particle size is fine, easy to disperse, chemically compatible with a variety of additives, and easy to prepare in the sol system. Storage and transportation must be moisture-proof to avoid the steaming of the hot sun, so as to ensure the long-term survival of its effectiveness.

Flame retardant of flexible polyurethane foam, which is prepared by a clear method. Compounds containing flame retardant elements such as phosphorus and nitrogen are selected as raw materials, and are mixed with polyols and isocyanates in proportion. First, the flame retardant is predissolved in the polyol, stirred slowly, in order to obtain a uniform solution. Then the isocyanate is injected, and the catalyst such as triethylenediamine and additives are added to gently react to release carbon dioxide and foam molding. The catalytic mechanism is that the catalyst promotes the rapid combination of isocyanate and polyol groups, and the cross-linking structure is formed. The flame retardant components are chemically or physically doped in the system to prevent the thermal decomposition chain of the polymer during combustion, releasing phosphoric acid and nitrogen oxides, forming a carbon layer, isolating oxygen, and achieving the effect of flame retardancy. The method has the advantages of smooth steps, simple process and excellent product performance.

The fire resistance of polyurethane soft foam lies in chemical reaction and modification. Flexible PU foam material is flammable by nature, so flame retardants need to be introduced. During this period, organophosphorus, nitrogen or halogen compounds are co-polymerized or mixed to embed in the polymer skeleton. In the chemical reaction process, isocyanate and polyol are the main agents, while flame retardants may participate in the reaction or embed in the physical structure to give novelty. Modification relies on phosphates and phosphonates as examples, which are cross-linked with the main chain to enhance the formation of the carbide layer and suffocate the flame. There are also nanoparticle modifiers, such as montmorillonite and silica, which are scattered in the network and have a significant barrier effect. The combination of chemical reaction and modification technology makes PU foam both soft and flame retardant, making it widely used in furniture, transportation, and other fields to soothe people and safeguard safety.

Flame suppressants, or flame retardants, are specially used in flexible polyurethane foams, and there are many similarities and differences in market names. Commonly known as flame retardants, or referred to by the English abbreviation FR, Flame Retardant, there are also names such as fire retardants, flame suppressants, flame retardants, etc. In fact, they have the same name, all of which are used to contain fire in flexible polyurethane. There are also merchants who create elegant names, such as Brominated Flame Retardant (brominated flame retardant), Phosphorus Flame Retardant (phosphorus flame retardant), such as Antiblaze, Fyrol, Safire, Flameban, Firemaster, etc. Although they are all used in different names. Shi Jia may be called flame retardant or arson slow-release agent, but they all refer to flexible PU sponge flammable, which needs to be used to make it difficult to spread. Taking its name is really interesting, but the effect is the same. It is applied to the home, car seat, and bedding industries to increase safety and avoid disasters.

Fire retardant, used in flexible polyurethane foam, is a necessity commonly used by craftsmen. However, it is related to safety, and the operation should be especially cautious. Its nature is slightly toxic. If it is not applied according to law, it is easy to cause harm. Therefore, before operation, it is necessary to read the attached instructions carefully to find out the nature. Work in a well-ventilated room with open windows to keep the air flowing smoothly. When applying, wear a mask, goggles and chemical-resistant gloves to prevent droplets from splashing into the eyes or sticking to the skin.
If the agent liquid touches the skin, rinse quickly with water, do not scratch. If you are not careful to enter the eyes, rinse with water for a long time, and rush to the doctor's office for diagnosis and treatment. Do not eat and smoke in the operation room to prevent the agent mist from entering the mouth and damaging the five internal organs. Flame retardants should be kept away from heat sources, sparks and open flames, stored in a cool and dry place, and the container should be tightly covered. Do not store with strong oxidants, strong acids and strong alkalis to avoid interaction and disaster.
After daily use, the residual liquid and containers should be cleaned up. The waste liquid should be classified and treated. Do not pour it into ditches, rivers and soil without authorization to protect the environment. Craftsmen or people with skin allergies should try it in a small place first to check its reaction. If you feel unwell, you should rest and seek medical attention as soon as possible. In case of leakage, collect it with sand and other adsorption, put it in a sealed vessel, and handle it properly. You should follow the operation process, carefully check the batch number of raw materials and the valid period, and do not use overdue products to ensure the same quality and complete efficacy.
After the work is completed, you must also wash your hands and face. Clothes should be changed in time to prevent residues. Where a fire is used, remove combustible materials from the surrounding area, and install fire extinguishing equipment for emergencies. All beginner apprentices must be trained, understand the operating procedures, and have a master to teach them when they go to work. Only by abiding by the norms and being cautious can they ensure personal safety, protect the workers Antai, and prosper in their careers.

A flame inhibitor, applied to soft polyurethane foam, is mild in nature, can suppress combustion and delay, and is widely used in indoor utensils. However, its toxicity concerns should not be ignored. Try the rats as an experiment, put it at a constant temperature, refer to the dose, drink or suck, and look at it for a day. Dissecting its five internal organs, it can be seen that the liver is slightly stained, and the lungs are slightly inflamed, but most of them have not been seriously damaged. The enzyme image in the blood floats, and it is still suitable. However, when exposed for a long time, it shows different resistance. A small amount of vapor can stimulate the reaction of the glands, and occasionally disturb their sanity. If high doses of acute infection, there will be convulsions, restlessness and other awesome. Chemical analysis shows that the flame retardant releases halogen soot during combustion, which is mildly incompatible with the trachea. For human use, it is necessary to carefully check its dosage and ventilation. In short, although this agent is inexpensive, it should also take into account the dangers and benefits.
