Problems solved by technology

[0004] Although PC-ABS composite plastics have certain flame retardant properties, the flame retardant effect is not good. In order to improve the flame retardancy of PC-ABS composite plastics, flame retardant additives containing halogen are usually added to improve PC-ABS composite plastics. But halogen-containing materials produce harmful gases after burning, which affects the environment; or adding antimony trioxide, magnesium hydroxide, aluminum hydroxide and other flame retardant additives can improve the flame retardancy of PC-ABS composite plastics, but due to the three Antimony oxide, magnesium hydroxide, aluminum hydroxide have poor compatibility with PC-ABS composite plastics, and the dosage is generally 40%-60%, which seriously affects the mechanical properties of PC-ABS composite plastics; additives, but the flame retardant effect needs to be improved
