Flame retardant of phosphate compounds
Since most phosphate flame retardants are liquid, volatile, good compatibility, thermal stability is bad, in order to solve this problem, now some people are developing the quality of polymer condensation and gathered in phosphate ester compounds. The representative products of these compounds are tetrahydroxybenzene diphosphate (RDP) and tetraphenyl bisphenol A diphosphate (BDP).
In addition, Brgh et al. also developed a phosphate flame retardant which is synthesized by phenolphthalein synthesis of n= 1. It is an oily liquid, adding 10% of the liquid to nylon, and the oxygen index can reach 25.6.
Alkyl phosphor flame retardant, the flame retardant effect is very significant. It can be used for flame retardant treatment of epoxy resin, unsaturated polyester resin, polyolefins and polyurethane resin.
Phenyl phosphate flame retardant is characterized by high rigidity, high heat resistance and good flame retardancy. The following highlights three kinds of flame retardants.
Some synthesis of 2 kinds of flame retardants, one kind is 4 - (2, 6 - dimethyl phenyl) resorcinol two phosphate (DMP - RDP), the other is a four (2, 6 - dimethyl phenyl) hydroquinone two phosphate (DMP - HDP), and 2 kinds of flame retardants respectively with phenolic resin compound matching flame retardant ABS resin, and and to study the thermal degradation behavior. The results of the test of oxygen index (LOI) showed that when 2 kinds of phosphor flame retardants and phenolic resin were 4:1, LOI was the largest and the flame retardant effect was good.
Researchers at shandong university in China recently synthesized several different polymerization degree (DP) aromatic polyphosphate, and investigated the relationship between DP and aggregate time and oxygen index (LOI). The experimental results show that when the polymerization time is 7 ~ 10 h of the PPP (DP) = 43 to 55 of the flame retardant of epoxy resin (E - 44) effect is best, and using the method of thermal analysis and IR spectra PPP the flame retardant mechanism of epoxy resin were discussed.
Isopropylphenyl Phosphate(IPPP50)Use:
Isopropylphenyl Phosphate, Flame Retardant IPPP50 This Product Is Compatible With Vinyl Chloride, Nitrocellulose, Synthetic Resin And Natural Resin, Etc. Because Of The Above Advantages, Reofos Series In Industrial Production Is Widely Used: PVC Film As Flame Retardant Plasticizer, Reofos Increase In The Amount Of Oxygen Index Increased, Enhanced Flame Retardant. In The Rubber Industry Can Be Used As Chloroprene Rubber And Rubber Flame Retardant Plasticizer; In Other Industries Can Be Used As Lubricants With Extreme Pressure Additives And Digestion Of Cellulose Paint, Resin, Phenol Resin And Other Flame Retardants.
Isopropylphenyl Phosphate, Flame Retardant IPPP50 Use Is Also Applicable To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin And Other Fields.
BDP has high molecular weight, low vapor pressure and high thermal stability. It can give the material better flame retardant effect and flame retardant durability. Like to join in the epoxy resin polymer nano organic montmorillonite (OMMT), and spread not only can improve the physical and mechanical properties of polymer materials, and can reduce the heat release rate of the material (HKR), improve the flame retardant performance of epoxy resin nanocomposites.
The polypropylene resin has excellent flame retardant properties for polypropylene resin.
Intermediates in the synthesis of chlorinated spiro phosphate A is A bifunctional reactive flame retardant, it can be with compounds containing - OH, - NH groups such as role, get A series of expansion type flame retardant, the polymer flame retardant performance is very good.
The experiments show that the phosphatates with pentaerythritol skeleton can form a protective film of coke layer when the polymer burns, so the flame retardant performance is excellent.
On this basis, the national professional flame retardant materials laboratory of Beijing university of technology has successively synthesized the products of PTDP and TDPP, including the flame retardant of bromide cage, and its structural formula is 3. The flame retardant can be used in flame retardant treatment of polyester resin and other materials.
Basic characteristics of phosphate flame retardant market
1) phosphate ester flame retardant technology research and development in China started late, now is still in the early stage of development, with the development of the synthetic materials industry, the current application domain expands unceasingly, people is more and more on the demand of phosphate ester flame retardant, so as to further promote the development of China's phosphate ester flame retardant industry.
2) the continuous increase in demand of phosphate ester flame retardants is an important series of organophosphorus flame retardants, which has both flame retardant and plasticizing effect. In recent years, the market demand has been expanding, the production enterprises are increasing, the sales proportion of flame retardants is increasing, and the proportion of profit and value added is high.
