Organophosphorus flame retardant for polystyrene
Organic phosphorus flame retardant for polystyrene is a kind of flame retardant which is equal to halogen flame retardant. It has many varieties and wide uses. Halogen flame retardants have many disadvantages, such as poor stability of ultraviolet resistance, burning more smoke, corrosive gas and toxic gas.
The study found that the pyrolysis of polybrominated diphenyl ether and two flame retardant polymer and combustion products contain carcinogens four bromo dibenzo two dioxane and four brominated dibenzofuran, using halogenated flame retardant is restricted to non halogen flame retardant especially polystyrene by the research and development of organic phosphorus flame retardant become more and more important.
Although organophosphorus compounds have certain toxicity, their teratogenicity is not high, and their decomposition products and their flame retardant polymers are thermally cracked and very few corrosive and toxic products are present in combustion products. Polystyrene with organic phosphorus flame retardant flame retardant is a hot topic of research, but also because of polystyrene with organic phosphorus flame retardant has the flame retardant performance, many varieties also have plastic, thermal stability and so on, it plays a very important role in improving the overall performance of polymer materials.
Classification, synthesis and application of organophosphorus flame retardants for polystyrene. At present, the research and development of organic phosphorus flame retardants for polystyrene are in the ascendant, and many related reports are reported every year. The main research methods include phosphate, phosphonate, phosphine oxide, phosphorus heterocyclic compounds, condensed phosphate and organic phosphate.
Phosphate flame retardant. Phosphate flame retardant is the main organic phosphorus flame retardant for polystyrene. It can be used as flame retardant for polystyrene, polyurethane foam, polyester, polycarbonate and liquid crystal. Phosphate flame retardants include phosphorus containing phosphate flame retardant, nitrogen containing phosphate flame retardant and halogen containing phosphate flame retardant and so on.
Phosphate flame retardant containing only phosphorus. Most of the flame retardants are phenolic phosphates. It is reported in the patent literature that compounds with structural formula can be used as flame retardant for high impact polystyrene.
Nitrogen containing phosphate flame retardant. Because of the two elements of nitrogen and phosphorus containing nitrogen, the flame retardant effect of nitrogen containing phosphate ester is better than that of phosphorus containing compound, so more and more attention has been paid to it. Nitrogen containing phosphate flame retardants mainly come from amines, two amines and melamine in the compounds. Matsuhara Chihiro reported the preparation, properties and applications of nitrogen containing phosphate flame retardant with the following structure. The compound has good thermal stability, compatibility, no frost spray and no color fading.
Nitrogen containing phosphate flame retardants with melamine as nitrogen source are also available. They can be used for flame retardancy of polymers such as PE.
Halogen containing phosphate flame retardants are much less reported because of the formation of corrosive gases and carcinogens after halogen burning. But because of the high efficiency of flame retardant, there are still some reports, most of them are chlorine, bromine phosphate or high halogen content of phosphate.

Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent
Phosphonate flame retardant. Phosphonate can also be widely used as flame retardant. At present, the research of phosphonate ester flame retardants mainly focus on two aspects: nitrogen containing phosphonate and reactive phosphonate ester flame retardant. It is reported in the patent literature that the cyano ester formed by the reaction of phosphate and cyanide has the function of flame retardancy and plasticization. Phosphonate is commonly used as reactive flame retardant.
Phosphine oxide flame retardant. The hydrolysis stability of phosphine oxide is better than that of phosphate ester. Phosphine oxide flame retardant can be divided into two types: additive type and reactive type. Phosphine oxide diol can be used in the manufacture of flame retardant polyester, polycarbonate, epoxy resin and polyurethane.
Phosphonic acid ester flame retardant. As a reactive flame retardant, the phosphonate ester flame retardant has a stabilizing effect and is widely used in polyester flame retardant treatment. It can be used as flame retardant, heat stabilizer, and also as flame retardant raw material for the synthesis of PET. These compounds were prepared by addition reaction.
Organophosphorus heterocyclic compounds flame retardant. Organophosphorus heterocyclic compounds are one of the most active fields in recent research on flame retardants, and also the research focus of organic phosphorus chemistry. This is because the structure and synthesis of organic phosphorus heterocyclic compounds have very important research value, and its application scope is expanding. There are five membered rings, six membered rings and spiro compounds in organic phosphorus heterocyclic flame retardants.
Five membered ring compounds containing phosphorus. The five element phosphorus heterocyclic flame retardant has less varieties, and the five membered phosphorus heterocyclic compound with the following structure is a good flame retardant, which can be used for flame retardancy of polyester, polyamide and polyolefin.
Six membered ring compounds containing phosphorus. The flame retardant is one of the main phosphorus heterocyclic flame retardants, mainly phosphorus phosphorus oxide, phosphate, cage phosphate, phosphonate and phosphonate, can be used for polyester, epoxy resin and polyurethane and other materials of flame retardant treatment. A cyclic phosphine oxide containing four carboxyl groups is a flame retardant curing agent for epoxy resin.
The thermogravimetric curves of epoxy resin cured with this curing agent are obviously different from those of other curing agents. At 600 degrees centigrade, the percentage of coke in the epoxy resin remains large.
