GLASS FIBER REINFORCED POLYPHENYLENE SULFIDE COMPOSITE WITH LASER ENGRAVING FUNCTION AND PREPARATION METHOD THEREFOR

摘要

The present invention relates to the technical field of high molecular materials, and in particular relates to a glass fiber reinforced polyphenylene sulfide composite with a laser engraving function and a preparation method therefor. The glass fiber reinforced polyphenylene sulfide composite with a laser engraving function consists of the following raw materials in parts by weight: 49.4-82.5 of a polyphenylene sulfide resin, 0-40 of a continuous glass fiber, 5-8 of a flexibilizer, 0.5-1.0 of a weather-resistant agent, 0.3-0.5 of an antioxidant, 0.3-0.5 of a lubricating agent, 3-5 of phlogopite, 1-2 of barium sulfate, 0.1-0.3 of a laser etching aid, and 0-1 of carbon black. The composite of the present invention has excellent mechanical properties, mechanical strength and weather resistance, and has an excellent laser engraving function at the same time, and black, white or gray, etc. distinctive laser markers, of which the strokes are clear and fine and smooth and the colors are obvious, long-lasting and will not fade, can be etched on substrates of different colors with a laser; and the preparation method therefor is simple and beneficial for popularization and application.
