Epoxy Resin Flame Retardant

Oxygen-based grease combustion is an essential element to ensure material safety. Its components are multi-terminal, but its core can be divided into two parts. At first, its base is oxygen-based grease, its properties are low, and its viscosity is low. However, oxygen-based grease is flammable in case of fire, and it is necessary to add fuel. For burning, its commonly used ones include phosphorus-based, nitrogen-based fillers, etc.
Phosphorus-based fillers, especially in the modern era, have both phase and condensed phase flame retardant functions. Its representative is phosphate ester, which is released into polyphosphoric acid by radiation, wrapped in the lipid surface, isolated in the air, and initially inhibited the spread of fire. Its decomposition materials can capture high-energy free radicals and reduce the reaction rate. In addition, phosphonate esters can also contribute to carbonization, which can be concentrated on the material surface, helping to prevent the amount of flammable fuel from escaping.
Elemental combustion, ancient and common, bromine-based is the most common. Its principle is to decompose biochemical radicals in case of fire, quickly intercept and ignite the active particles, and ignite the burning type. However, the element is not used for combustion or harmful escape. In recent years, it has been limited by protection laws, so it is gradually used less.
Nitrogen-based combustion, such as melamine derivatives. When it decomposes, it absorbs energy and releases inert energy, stimulates the material to slightly expand and cause bubbles, and generates dense carbon. Fillers, such as oxidation, oxidation, flame absorption, release of crystalline water, dilute oxygen and combustible molecules, reduce the temperature and suppress the flame.
As mentioned above, the core components of oxygen grease combustion, such as oxygen, phosphorus, nitrogen and other multi-system flame retardant aids, have the same fire protection function. Appropriate compatibility, not only can maintain safety, but also does not affect the inherent properties of the material.

Oxygen grease flame retardants are widely used in a wide range of fields, such as electronics, construction, etc., and their poor flame retardant properties are especially important for the safety of utensils. Today, those who measure the flame retardant properties of oxygen grease often use multiple methods. The world's most common methods include UL 94, IEC 60695, China GB/T 2408, etc. The main purpose of its text is to measure the combustion of materials.
UL 94 is established by the United States. The method is divided into V-0, V-1, V-2 and other three types. The method is to place the material vertically or horizontally and apply a flame to measure its self-extinguishing and dripping. For V-0, the ignition stop is less than ten seconds, and the fuel is dripped. IEC 60695 is designed by the working committee to ensure the safety of the components under flame, and its components are not damaged. In addition, China's national standard GB/T 2408 is similar to UL 94, which is also divided into V-0, V-1, V-2, etc., to indicate the ability of the material to suppress the rate of ignition when exposed to fire.
In addition to the above, there is ISO 4589 (limited oxygen refers to LOI), which is used to measure the combustion of the material in an atmosphere with a specific oxygen content. The higher the value, the better the flame resistance of the material. There is also ASTM E84, which is used to build the surface burning speed of the material, and the fruit is divided into 4. In other words, qualified oxygen-based flame retardant products must meet one or more of the above requirements.
In the case of flame retardant oxygen-based grease, compounds such as phosphorus, nitrogen, and other elements are often used as flame retardants to decompose under the action of flame, forming protection or inhibiting free radicals, so as to delay combustion or self-extinguishing effect. In general, the product can be injected with characteristic values such as V-0 (UL 94) or LOI > 26. However, it is noted that the compliance with the basic requirements is sufficient to ensure the safety and integrity of the product and not cause any harm.
is the most common reason for the flame retardant properties of oxygen grease, and the above factors are also important for combustion, delay and material safety. Only by following the rules and seeking products carefully can we meet the increasingly stringent requirements and ensure people's peace of mind.

Epoxy resin is also an important material in today's industry, and is widely used in many fields such as coating, gluing, casting and composite materials. However, its nature is flammable, and it will generate smoke and flames in case of fire, which is a huge hidden danger. Therefore, craftsmen then use flame retardants to complement it to improve the fire resistance of epoxy resins. Flame retardants are mostly compounds of elements such as phosphorus, nitrogen, and bromine, which release gases that can block combustion at high temperatures, or promote the formation of carbonized films to isolate heat sources.
However, when flame retardants are introduced, they actually interact with the resin body. Changes in physical properties should not be underestimated. Probably the addition of flame retardants hinders the inherent molecular arrangement of epoxy resins. Therefore, it has a great impact on mechanical strength, impact toughness, and bonding properties. When the molecular chain is broken, the elongation at break decreases; when it is heavy, the cohesion decreases, so that its fatigue resistance decreases. Especially halogen and phosphorus series are the main ones, which often cause the original hardness and elasticity of the resin to decrease, and the thermal stability may be slightly inferior.
However, flame retardants are also polymorphic. If new organophosphorus, halogen-free micro-nano flame retardants are used, and supplemented by polymer modification, the resin body structure can be partially maintained and the performance decline can be slowed down. The delicate process and the appropriate dosage can also combine flame retardancy and mechanical properties. Chemists often use the help of dispersants and additives to improve the compatibility of the flame retardant system, which can reduce the performance degradation.
In summary, flame retardants can significantly increase the fire resistance of epoxy resins, but their physical properties are more or less damaged. The success or failure depends on the adjustment of the ratio and the selection of agents. If it can be applied rationally and used in harmony, although there are profits and losses, it can still seek advantages and avoid disadvantages and meet the needs of practical projects.

Where oxy resin (Epoxy Resin) is fireproof, it is necessary to add flame retardant oil to the package. It is essential for safety to make the product non-flammable. However, the amount of proportion should be carefully considered, and it is not possible to rate it. Nowadays, according to ancient and modern times, flame retardancy is often measured as a percentage, and it is necessary to reduce fire resistance, etc. As shown in the report, the amount of addition is between 5 and 25%. To obtain UL94 V-0, etc., it may be necessary to add it to 20%. If general fire protection is required, it may be appropriate to about 10%.
However, the use of material properties, the ratio needs to be both high and low. If too much is added, it will cause ignition, natural material properties or low consumption, and it is easy to cause brittle cracking; if there is too little, the flame retardant effect will not be obvious. Every time the engineer uses the product, it will be adjusted according to the thickness of the product, flame resistance, etc., and the processing method. There are many types of flame retardants, such as dioxide trioxide, phosphorus, oxides, etc., each of which should be avoided. The flame retardant element is effective, but it may be toxic. Nowadays, there are many types of protection.
It is necessary to make the flame retardant grease mix evenly, which is easy to cause local efficiency imbalance and affect the overall performance of the product. In the process of mixing and curing, the compatibility of flame retardant hardening is still noted. If the phase compatibility is not good, the solidification will be incomplete, and the amount of reaction will decline, which will only increase the problem.
As far as the flame retardant strategy of oxygenated grease is concerned, the proportion of addition and distribution should be controlled, and the uniformity should not be limited. For those who combine both safety and performance, small batches are often used, and the order is completed to the ideal. It is appropriate to use it in all industries according to the standard. Only by knowing, adding the wonders of flame retardancy, understanding the basic principle, and exploring the three can it be achieved.

Oxygen grease, which is flame retardant, is brittle and prone to fire, so its storage is difficult, and it is necessary to abide by the law carefully. In the place where it is stored, it should be a place where things are dry and clear, the source of fire and high temperature, so as to prevent it from being damaged or causing ignition. The device is not suitable to prevent water from entering, its absorption is not good, and the product is not affected by moisture. Light should also be avoided, and the grease will be colored or deteriorated for a long time. Therefore, it is advisable to use opaque utensils to prevent the sun and the moon from invading. If there are insulating ingredients, it is even more necessary to isolate open flames and sparks, and to prevent explosion.
The room where it is located, the ground is flat and clean, and there are measures to prevent fire from colliding with each other, plus warnings and fire equipment. In the month of hot summer, it is forbidden to be exposed to the scorching sun and cold in winter to avoid cracking ice vessels. The shelf life is limited, and it is necessary to seal the contents of the product regularly. It is often separated and processed, and the damage may be caused.
, also need to be very careful. Move the warehouse and put it away, and it is forbidden to prevent the package from breaking and fat leakage. Tools, suitable for those who use dangerous chemicals,

Fat flame retardant materials are inherently dangerous to the chemical industry. If you keep them safe, you will be safe at first, and you can't be safe. Only in this way can you ensure the completion of its performance and the safety of the person.
