Abstract

The invention discloses a stress-cracking-resistant polycarbonate composite material which comprises the following components in percentage by weight: 30-80% of polycarbonate, 1-50% of ABS (acrylonitrile-butadiene-styrene) polymer, 0-50% of crystalline polyester PBT (polybutylene terephthalate) and / or crystalline polyester PET (polyethylene terephthalate), 0.1-10% of TPP (triphenyl phosphate), 0.1-10% of MBS (methyl methacrylate-butadiene-styrene) and 0.1-15 parts of BDP and / or RDP. By adopting the specific-structure polycarbonate and ABS polymer and adding the specific-content TPP into the composite material, the comprehensive properties of the composite material are improved, so that the composite material has favorable stress cracking resistance and processability, and is especially suitable for occasions with high requirements for indoor and outdoor operating environments.

Description

technical field [0001] The invention relates to a polycarbonate composite modified material and a preparation method thereof, in particular to a polycarbonate composite material resistant to stress cracking and a preparation method thereof, belonging to the field of polymer materials. Background technique [0002] Polycarbonate has excellent electrical insulation, elongation and dimensional stability, as well as self-extinguishing, easy to enhance flame retardancy, non-toxic, hygienic, easy to color and other excellent properties, and can be widely used in machinery, automobiles, aerospace, Electronics, electrical appliances, construction, information storage, agriculture, transportation and other fields. [0003] The commonly used method to improve the stress cracking resistance of polycarbonate is to improve the stress cracking resistance of the material by adding glass fibers, which are mentioned in patents CN104356625A and CN1153814C; Adding special functional groups ca...
