Problems solved by technology

The above patents all use short glass fiber reinforced polyphenylene sulfide resin to prepare composite materials, and there are also too long glass fiber reinforcements, but in the end they will be prepared into particles and then produced into products. This kind of similar process method not only produces composite materials The mechanical strength is low, especially the tensile strength is low, and the process is relatively complicated, and the environmental pollution is large
[0004] In addition, the currently used release agent will cause residual release agent in the product, and the residual release agent will affect the subsequent processing such as painting and plating, especially for the appearance quality of the exterior parts.

Abstract

The invention provides a preparation method of a continuous glass fiber cloth reinforced polyphenylene sulfide composite material. The preparation method comprises the following steps: 1) a coupling agent is sprayed to the surface of cut glass fiber cloth; and the cut glass fiber cloth is baked by 400 minutes in an oven with a temperature of 125+-5 DEG C; 2) a polyphenylene sulfide film is cut, and is baked by 400 minutes in an oven with a temperature of 100+-5 DEG C; 3) the glass fiber cloth in the step 1) and the polyphenylene sulfide film in the step 2) are laminated according to the following structure: one layer of the polyphenylene sulfide film, one layer of the glass fiber cloth, one layer of the polyphenylene sulfide film, one layer of the glass fiber cloth and one layer of the polyphenylene sulfide film are circularly laminated according to the structure; and 4) the laminated structure obtained in the step 3) is isolated by adopting a copper foil, and is finally placed betweentwo layers of steel plates flatly to put in a high-temperature laminating machine to prepare the continuous glass fiber cloth reinforced polyphenylene sulfide composite material.

Description

Technical field [0001] The invention belongs to the field of plastics, and particularly relates to a continuous glass fiber woven reinforced polyphenylene sulfide composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide is a special engineering plastic with excellent comprehensive performance. Polyphenylene sulfide has excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced physical and mechanical properties, very good dimensional stability and excellent electrical properties.
