Abstract

The invention provides a low temperature-resistant halogen-free flame-retardant polycarbonate composition. The composition comprises, by weight, 20 to 30 parts of polycarbonate, 0.3 to 1 part of a polysiloxane-polycarbonate random copolymer, and 8 to 15 parts of an acrylonitrile / butadiene / styrene terpolymer. A mass ratio of polycarbonate to polysiloxane-polycarbonate random copolymer is 20: 0.3 to 1. The polysiloxane-polycarbonate random copolymer comprises 5-20% by weight of the polysiloxane block. The polycarbonate composition has the advantages of simple preparation processes, low cost and high flame retardancy.

Description

technical field [0001] The invention relates to a low-temperature-resistant halogen-free flame-retardant polycarbonate composition and its application. Background technique [0002] Polycarbonate is a synthetic material developed in the late 1950s. Its visible light transmittance is above 90%, and it has outstanding impact resistance, creep resistance, good dimensional stability, chemical resistance, heat resistance, and water absorption. Low, non-toxic, excellent dielectric properties, self-extinguishing, easy to enhance flame retardancy and other excellent properties, are widely used in electronic and electrical, electric tools, transportation, automobiles, machinery, instruments, construction, information storage, optical materials It is the only product with good transparency among the five major engineering plastics, and it is also the fastest growing general engineering plastic in recent years. Due to the limitation of technology, except for some foreign monopoly ente...
