Problems solved by technology

[0003] However, due to the lack of aromatic groups in the main molecular chain of ABS resin, it is difficult to achieve V-0 level with the commonly used phosphorus-based flame retardants, nitrogen-based flame retardants or inorganic flame retardants. If the amount is high, it will seriously deteriorate the mechanical properties of the material
[0004] Another direction for the development of non-halogenated flame-retardant ABS materials is to use polycarbonate or polyester to form an alloy with ABS, and then add the currently commonly used halogen-free flame retardants to prepare PC / ABS or PET / ABS and other halogen-free flame-retardant ABS. Alloy, its various properties have been significantly improved compared with the previous method, and it can also achieve a higher flame-retardant grade, but its cost is much higher than that of ordinary flame-retardant ABS, and there are processing difficulties, so its wide application is restricted. a certain degree of restriction
