The composite material is prepared by using the following components, by weight, 50-70 parts of polyphenylene sulfide, 40-60 parts of semi-aromatic nylon, 10-30 parts of a glass fiber, 10-20 parts of an inorganic mineral filler, 1-15 parts of a compatilizer, 0.5-2 parts of an antioxidant and 1-3 parts of a lubricant. The material disclosed in that invention has the advantages of low molding shrinkage, good dimension stability, high toughness, excellent high temperature resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer material processing and modification, and relates to a polyphenylene sulfide / semi-aromatic nylon composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide resin (PPS), also known as polyphenylene sulfide, has good comprehensive properties, high temperature resistance, corrosion resistance, radiation resistance, non-combustibility, and good mechanical and electrical properties. However, polyphenylene sulfide resin has low impact strength and poor bending resistance; moreover, PPS has high melt viscosity, poor fluidity, and poor processing performance; at the same time, its cost is relatively high compared with general engineering plastics. These shortcomings limit polyphenylene sulfide. The scope of application of ether resin. Semi-aromatic high-temperature-resistant nylon series materials represented by nylon 6T, 9T, 10T, 12T, etc. have excellent wea...
