Hydroxide flame retardant for Polypropylene
The particle size of magnesium hydroxide thin, less wear on the equipment, to prolong the service life of processing equipment, and easily obtained raw materials, low production cost, can be widely used in polypropylene, polyethylene, polyvinyl chloride, high impact polystyrene and ABS etc..
Magnesium hydroxide flame retardant project group, Qinghai Institute of Saline Lake, Chinese Academy of Sciences, using a new conversion agent system, using ordinary magnesium hydroxide as raw material, through the hydrothermal modification, obtained 6 angle magnesium hydroxide flame retardant with complete crystal shape.
The key technical and economic indexes of the flame retardant for polypropylene used in the scale-up process of industrial test have reached the international advanced level, which can provide the basis for the industrial production of polypropylene hydroxide flame retardant.
Researchers in Qinghai Saline Lake Research Institute of the Chinese Academy of Sciences, Academy of science and technology in Chinese branch green projects and science and Technology Department of Qinghai Province under the support of process conditions on the synthesis of magnesium hydroxide was improved, the successful synthesis of high purity and ultrafine magnesium hydroxide, preparation of six angle sheet of flame retardant magnesium hydroxide particle size reached the expected target.
Magnesium hydroxide, white amorphous powder. Alias caustic magnesite, light burned magnesia, magnesium hydroxide in water suspension called magnesium hydroxide emulsion, referred to as the name for the Magnesium hydroxide English magnesiumless. Magnesium hydroxide is colorless six square column crystal or white powder, insoluble in water and alcohol, soluble in dilute acid and ammonium salt solution, aqueous solution is weak alkaline.
The solubility in water is very small, but the part dissolved in water is completely ionized. The concentration of saturated aqueous solution was 1.9 mg / L (18 C). When heated to 350 degrees, the aquatic Magnesium Oxide was lost. Natural mineral brucite of magnesium hydroxide. It can be used for sugar and Magnesium Oxide. Because magnesium hydroxide is rich in nature, and its chemical properties are similar to that of aluminum, users begin to use magnesium hydroxide instead of aluminum chloride for fragrant products. It can be used as analytical reagent and also used in pharmaceutical industry.
Polypropylene with hydroxide flame retardant key technology and equipment unit enlargement experiment completed with hydroxide flame retardant industry test key technologies for the development of polypropylene, to determine the correlation between multiple unit amplification and the process conditions and reasonable process and optimizing the process conditions.
At present, brominated flame retardant is the main flame retardant material, and brominated flame retardant is a large family of flame retardants, with more than 70 members. Bromine is widely found in nature, especially in sea water, salt lake and soil. The production and application of brominated flame retardants has a long history, production technology and application technology is very mature and widely used in electronic and electrical products, not only reduce the incidence of electronic and electric products in the fire, but also good stability, even after years of service in accordance with the new standards of fire safety, more valuable is in regeneration in the process of material circulation, can still maintain good stability. Brominated flame retardants are believed to affect the environment, and most bromine products have been banned by the EU's 2 directives.

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.
Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.
Magnesium hydroxide as flame retardant agent for magnesium hydroxide: thermal decomposition of water, at the same time to absorb a large amount of latent heat, thereby inhibiting polymer decomposition temperature rise, and reduce the burning rate of continuation of the heat, which reduces the resin in the flame of the actual bearing temperature, a cooling effect inhibiting polymer decomposition and producing a combustible gas. Magnesium Oxide is born after the decomposition of refractory material good, cut off the supply of oxygen, prevent flammable gas, the ability to help advance resin flame resistance, thermal decomposition of magnesium hydroxide and high temperature of 340 DEG C, so the magnesium hydroxide as a flame retardant and its flame retardant properties superior to ten points.
When the medium is filled with magnesium hydroxide, the thicker carbon oxide layer can appear. The carbonization layer naturally blocks the heat and oxygen entering and the escaping of flammable gas, and makes the dehydration, dilution and endothermic cooling play a greater role. Adding the magnesium hydroxide reduces the initial oxidation decomposition temperature, and decreases with the increase of the dosage. In addition, the natural Magnesium Oxide makes good refractories cover the surface of polymers, and also improves the ability of polymers to resist flame.
With the other two kinds of inorganic flame retardant calcium carbonate and aluminum hydroxide magnesium hydroxide is compared to the precombustion zone and the effect of the combustion area is small, but the flame retardant effect occurred in the solid region is much higher than the degradation of calcium carbonate and aluminum hydroxide in smoke effect is also very obvious. Magnesium hydroxide as a non-toxic flame retardant for polypropylene, polyethylene, polyvinyl chloride, three EPDM and unsaturated polyester polymer materials such as flame retardant and smoke. Polyolefin plastics is especially suitable for high temperature processing.
Magnesium hydroxide belongs to additive inorganic flame retardant, and has better smoke suppression effect compared with similar inorganic flame retardant. Because 80% of the fire died from suffocation, the "smoke suppression" in the modern flame retardant technology is more important than "flame retardant".
Magnesium hydroxide has no harmful substances emission in the process of production, use and waste, and can neutralize acid and corrosive gases produced during combustion. It is an environmentally friendly green flame retardant.
The thermal decomposition temperature of magnesium hydroxide is higher than that of inorganic flame retardant aluminum hydroxide, which is 140 times higher than that of the inorganic flame retardant. The magnesium hydroxide can endure higher processing temperature, accelerate the extrusion speed, shorten the molding time, and also improve the flame retardant efficiency.
