Abstract

The invention discloses a high-temperature-resistant and low-shrinkage polyarylester fiber master batch / polypropylene composite material and a preparation method thereof. The polyarylester fiber master batch / polypropylene composite material is prepared by the steps of rapidly and uniformly mixing the following components in parts by weight: 40-60 parts of polypropylene, 20-40 parts of polyarylester fiber master batches, 15-30 parts of a mineral filling agent, 1-3 parts of a compatilizer, 5-15 parts of a flexibilizer, 0.3-0.6 part of an antioxidant and 0.5-1.2 parts of a lubricant, and extruding and granulating by virtue of an extruder. The polyarylester fiber master batch / polypropylene composite material has the advantages of high temperature resistance, low shrinkage and high impact strength and bending modulus and can be widely applied to the fields of electrics, electrons and automobiles and other protection fields.

Description

Technical field: [0001] The invention relates to the technical field of modified plastics, in particular to a polyarylate fiber masterbatch / polypropylene composite material with high temperature resistance and low shrinkage and a preparation method thereof. [0002] Background technique: [0003] Acrylonitrile-butadiene-styrene plastic (ABS) has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size and good surface gloss. , easy to paint and color, and can also carry out secondary processing such as metal spraying, electroplating, welding, hot pressing and bonding on the surface. It is widely used in industrial fields such as machinery, automobiles, electronic appliances, instruments, textiles and construction. A versatile engineering thermoplastic. [0004] The polypropylene (PP) material is widely used because of its excellent heat ...
