At present, there are many types of flame retardants that can be used in nylon. Brominated flame retardants such as decabromodiphenyl ether and decabromobiphenyl ethane. Phosphorous flame retardants such as red phosphorus, melamine, and cyanurate (MCA). , Solid flame retardants such as antimony trioxide, zinc borate, etc., synergistic effects between some flame retardants.

From the perspective of use effect and dosage, halogen-containing flame retardant systems are the most widely used in nylon flame retardant systems. Among the halogen-containing flame retardant systems, polybrominated styrene is widely used abroad. It is a homopolymer of dibromostyrene. It has excellent thermal stability and good miscibility with nylon. Has good fluidity, but its poor light stability and high cost have not been widely used in China; Decabromodiphenyl ether is widely used in China because of its higher bromine content, less addition, and flame retardant effect Good and low cost, it has become the most economical type of flame retardant preferred by many domestic enterprises, but it releases harmful gases and toxic substances DPO (so-called dioxins) when it is burned. Harmful. In recent years, due to the promulgation of the EU RoHS / WEEE directive, experts and scholars in the industry are committed to finding practical and efficient environmentally friendly halogen-free flame retardants. The most widely used halogen-free flame retardant systems are red phosphorus and melamine salts. However, because of its color, red phosphorus can only be used for black products, and it is generally only used in nylon 6, and its application range is very narrow. In addition, the more common applications are melamine salts, mainly melamine urate and phosphate. However, its flame retardant effect is not good, the added amount is large and it cannot reach a high flame retardant level, and it can only be applied to the occasions where the flame retardant requirements are not high.

Based on this, in recent years people have developed a new type of environmentally friendly flame retardant decabromodiphenylethane, which has the same high bromine content and good flame retardancy as decabromodiphenyl ether, but it has good It has the advantages of thermal stability and light stability, and is not easy to bloom. It can be used in nylon instead of decabromodiphenyl ether.
