Abstract

The invention relates to a PBT-PC (Polybutylene Terephthalate-Polycarbonate) composite material and a preparation method thereof. The PBT-PC composite material is prepared from the following components in parts by weight: 60 to 80 parts of PBT, 30 to 40 parts of PC, 10 to 14 parts of ASA (Acrylonitrile Styrene Acrylate), 8 to 12 parts of nano sinoceras particle, 4 to 6 parts of wear-resisting agent, 0.1 to 0.3 part of compatilizer and 0.1 to 0.5 part of antioxidant. According to the application, the PBT-PC composite material which uses the ASA as a framework is made, is excellent in notch impact strength, tensile strength, wear resistance and weather resistance and has great popularization significance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PBT-PC composite material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT) is an important thermoplastic polymer with good dimensional stability, good insulation and oil resistance. It is widely used in household appliances, mechanical parts, office supplies and communication equipment and other fields. With the improvement of people's living standards, there are higher and higher requirements for the materials used. PBT is sensitive to notched impact strength, wear resistance, and weather resistance, which limits the application range of PBT composite materials to a certain extent. [0003] In view of this reason, the applicant innovatively used PC, quartz powder and Tai Chi stone to modify PBT, and finally made a PBT-PC composite material with excellent notched impact strength, tensile strength, wear resistance and wea...
