Abstract

The invention relates to the technical field of high polymer materials and in particular relates to a glass fiber reinforced polyphenylene sulfide composite material with a laser engraving function and a preparation method of the composite material. The glass fiber reinforced polyphenylene sulfide composite material with the laser engraving function comprises the following raw materials in parts by weight: 49.4-82.5 parts of polyphenylene sulfide resin, 0-40 parts of continuous glass fibers, 5-8 parts of a flexibilizer, 0.5-1.0 part of a weather-resistant agent, 0.3-0.5 part of an antioxidant, 0.3-0.5 part of a lubricating agent, 3-5 parts of flogopite, 1-2 parts of barium sulfate, 0.1-0.3 part of laser etching aids and 0-1 part of carbon black. The composite material disclosed by the invention has excellent mechanical property, mechanical strength and weather fastness and also has an excellent laser engraving function, and black, white or gray distinctive laser markers of which the strokes are clear and smooth and the colors are obvious and long-lasting and do not fade can be etched in substrates of different colors with laser; and moreover, the preparation method is simple and can be favorably popularized and used.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a glass fiber reinforced polyphenylene sulfide composite material with a laser engraving function and a preparation method thereof. Background technique [0002] In recent years, with the diversification of people's demand for the appearance of electronic products, the appearance quality of electronic products is constantly changing. The single metal or plastic casing of electronic products can no longer meet the diversified market needs. Combined electronic product casings have become people's new favorite. Some of the more popular electronic product fuselages on the market are the products of the combination technology of aluminum alloy surface treatment and resin polymer. At the same time, various information such as production date, barcode, company slogan, serial number, etc. need to be marked on this type of electronic product. . And commonly used marking techno...
