Abstract

The invention provides an antistatic glass fiber reinforced PBT/ASA composite material and a preparation method thereof. The composite material comprises the following ingredients (by weight): 20-30 parts of polybutylene terephthalate, 15-25 parts of ASA resin, 10-20 parts of glass fiber, 5-10 parts of a compatilizer, 1-5 parts of an anti-oxidant, 1-5 parts of a dispersant, 1-5 parts of an antistatic agent and 1-5 parts of a liquid additive. Under the precondition of guaranteeing excellent properties such as high strength, good electrical property, dimensional stability, good heat resistance,low water absorption and easy forming, the antistatic property of the composite material is enhanced. The invention brings greater profit margins for the application of PBT/ASA plastic alloy.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to an antistatic glass fiber reinforced PBT / ASA composite material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT) is an engineering material with high strength, good electrical properties, stable dimensions, good heat resistance, low water absorption and easy molding and processing. It is widely used in automobiles, electronics Electrical appliances and machinery manufacturing industries have become the fifth largest engineering plastics. [0003] However, the notched impact strength of PBT resin is low and the molding shrinkage is large. These problems limit the development and application of PBT resin in some fields to a certain extent. [0004] The introduction of ASA makes the alloy have excellent mechanical properties, dimensional stability, chemical resistance, weather resistance, etc., which expands th...
