Abstract

The invention discloses a short glass fiber reinforced polyphenylene sulfide resin material and a preparation method thereof. The short glass fiber reinforced polyphenylene sulfide resin material comprises the following raw materials in percentage by weight: 45-66.2% of polyphenylene sulfide, 30-45% of short glass fibers, 0.3-0.5% of an antioxidant, 0.5-1.5% of a lubricating agent and 3-8% of a compatilizer. According to a synergistic effect of the compatilizer and the lubricating agent, the short glass fibers are prevented from floating out of the surface during processing, and the problems that burrs easily appear on the polyphenylene sulfide surface and the glossiness is poor are effectively solved. Meanwhile, the mechanical property of the polyphenylene sulfide is improved, and the prepared short glass fiber reinforced polyphenylene sulfide resin material is high in appearance quality.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a chopped glass fiber reinforced polyphenylene sulfide resin material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS for short) is a new type of high-performance thermoplastic resin, which has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties.
