Description

technical field

[0001] The invention belongs to the field of environmentally friendly brominated flame-retardant nylon, and in particular relates to a high heat-resistant flame-retardant nylon 66 composite material. Background technique

[0002] Polyamide resin has excellent mechanical properties, barrier properties, heat resistance, wear resistance, chemical corrosion resistance and other comprehensive properties, and is widely used in machinery manufacturing, electric tools, electronic appliances, transportation and other fields. Decabromodiphenylethane is a highly efficient brominated flame retardant, which can be widely used in plastics, fibers, etc., especially in engineering plastics. In the early 1990s, decabromodiphenyl ether was widely used, but because the European Union pointed out that decabromodiphenyl ether would produce toxic and carcinogenic polybrominated dibenzodioxanes and polybrominated dibenzofurans when burned, And make it slowly withdraw from the mark...
