Usage: used as additive of unsaturated polyester and polyurethane resin to make them have flame retardancy; Adding to nylon can improve the degree of polymerization; As an extreme pressure agent, it can be added to lubricating oil; Used as catalyst for esterification of carboxylic acid and alcohol; When treating fiber, its flame retardant function can be improved; It can also be used as raw materials for organic synthesis
Preparation or source: With thiobenmethylphosphine dichloride as raw material, it is oxidized to produce native phosphonic acid green, which is hydrolyzed in alkaline solution Flame retardant series flame retardants: at present, they mainly include organic and inorganic, halogen and non halogen
Composition of Flame Retardants: organic flame retardants are some flame retardants represented by bromine, nitrogen and compounds, and inorganic flame retardants are mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon and other flame retardant systems (1) According to the flame retardant elements contained, flame retardants can be divided into halogen flame retardants, phosphorus flame retardants, nitrogen flame retardants, phosphorus halogen flame retardants, phosphorus nitrogen flame retardants and so on
(2) According to different components, it can be divided into inorganic salt flame retardants, organic flame retardants and organic and inorganic mixed flame retardants
(3) According to different methods of use, flame retardants can be divided into additive type and reactive type , Guidance price 220
