Function of eco friendly magnesium hydroxide flame retardant
 
It is well known that the fire brings the civilization to the human race and the nature, however it also brings disaster to mankind in today's civilized world. In recent years, fires caused by the burning of various materials that have become more frequent in the world, which resulting in a large number of casualties and huge economic losses. With the development of the polymer materials industry and synthetic materials such as plastics, rubber, and fibers, which is increasingly used in construction, chemical, military, and transportation fields. Due to the flammability of polymer materials, the flame retardant technologies have received global attention. As early as ***0s, some industrialized countries began to use the flame retardant materials for polymers and other materials. Some countries have also formulated flame retardant standards and fire regulations for various materials. In addition to the direct selection of polymer materials with high oxygen index and low calorific value, the flame retardant technology of polymer materials is adding flame retardant.
 
Classifications of eco friendly magnesium hydroxide flame retardant
 
According to different chemical compositions, flame retardants can be divided into two categories: organic flame retardants and inorganic flame retardants.
Organic flame retardants mainly include the halogen flame retardants, such as bromine and chlorine flame retardants.
Organophosphorus flame retardants mainly includes phosphates and phosphonates.
Intumescent flame retardant mainly includes nitrogen and phosphorus series.
Inorganic flame retardants mainly includes antimony-based flame retardants, antimony trioxide and antimony pentoxide, etc.
Aluminum-magnesium flame retardants mainly includes magnesium hydroxide and aluminum hydroxide flame retardants.
Inorganic phosphorus flame retardant agents, mainly includes red phosphorus and polyphosphoric acid.
Boron flame retardants mainly includes zinc borate.
Molybdenum flame retardants mainly includes molybdenum trioxide and ammonium octamolybdate.
 
With the growing demand for environmental protection, flame retardants are developing towards environmentally friendly inorganic flame retardants, which are efficient, inexpensive, halogen-free, and non-polluting. Magnesium hydroxide is considered to be the most promising and environmentally friendly inorganic flame retardant because of its advantages of good heat stability, non-volatilization, no toxic gas generation, no corrosion processing equipment, and obvious smoke elimination.
 
Working principle of eco friendly magnesium hydroxide flame retardant
 
The flame retardant mechanism of the flame retardant is relatively complicated, but its function is to cut off the combustion cycle and the generation of smoke through physical and chemical action. Magnesium hydroxide is a raw material of chemical, which is rich in water of crystallization. It begins to decompose when heated to **0 °C, releasing a large amount of water of crystallization, while as absorbing a large amount of latent heat, thereby inhibiting the temperature rising of the polymer, delaying its thermal decomposition and reducing the burning rate. The actual temperature withstanding the resin in the flame is lowered, and the cooling effect of suppressing the decomposition of the polymer and the generation of the combustible gas is obtained. The magnesium oxide is formed after decomposition from a good refractory material, which can cut off the supply of oxygen, prevent the flow of flammable gas, and help to improve the resin's ability to resist flame.
 
Application of eco friendly magnesium hydroxide flame retardant
 
The basic research and application research of magnesium hydroxide is very extensive and wide-ranging. Compared with the other two inorganic flame retardants, which are calcium carbonate and aluminum hydroxide, magnesium hydroxide has a superior flame retardant effect in the solid degradation zone, and is also very effective in suppressing smoke. When the magnesium hydroxide flame retardant is used alone, the flame retarding effect is low and the amount of addition is large. Therefore, the surface modification of magnesium hydroxide is often carried out and mixed with other flame retardants to improve the flame retarding effect. The silane coupling agent is mixed with calcium stearate and magnesium oleate to modify the surface of magnesium hydroxide, which not only achieves the purpose of improving the surface properties of magnesium hydroxide, but also forms a good carbonized structure when the polymer material is burned, thereby improves the flame retardant and mechanical properties of the material.
 
Advantages of eco friendly magnesium hydroxide flame retardant
 
The use of natural brucite to produce eco friendly magnesium hydroxide flame retardant is an ideal choice. It is not only low in cost, but also widely used in large quantities. China is currently the world's largest proven reserves of brucite. The supply of raw materials has established a good foundation for the direct production of magnesium hydroxide by domestic development of brucite. The development direction of flame retardant is to use halogen-free flame retardant instead of normal flame retardant, and inorganic flame retardant to replace organic flame retardant. Eco friendly magnesium hydroxide flame retardant is undoubtedly an excellent flame retardant, which with the application of green chemistry and technology in the field of flame retardant, is still in its infancy. The high-efficiency, smoke-suppressing, non-toxic and harmless flame retardants, especially environmentally friendly magnesium hydroxide flame retardants is the proper choice for the company used the old school flame retardant, which is all for security.
