POLYCARBONATE COMPOSITION AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2016/188474

Kind Code:

A1

Abstract:

Disclosed is a polycarbonate composition, comprising the following components in parts by weight: a. 30-80 parts of a polycarbonate; b. 8-50 parts of a graft copolymer; c. 5-25 parts of a flame retardant; d. 0-10 parts of other additives. The sum of the parts by weight of a, b, c and d is 100 parts. On the basis of the total weight of the polycarbonate composition, the total compounding amount of a phenol substance and a metal manganese element added to a polycarbonate composition formulation does not exceed 500 ppm, so that the fluidity of the polycarbonate composition is good, the polycarbonate composition has colour stability and a high gloss before and after long-term thermo-oxidative aging, and the polycarbonate composition is particularly suitable for use in a situation having relatively high environmental requirements. The structural formula of the phenol substance is shown in formula (1), wherein R1 and R5 represent hydrogen groups, alkyl groups, alkoxy groups, hydroxy groups, carboxyl groups or carbonyl groups, with the exception of hindered groups, or ester groups, and R2, R3 and R4 represent hydrogen atom-containing substituents, preferably hydrogen atoms.
