Abstract

The invention discloses a preparation method of a heat-resistant plastic product. The preparation method of the heat-resistant plastic product comprises the following steps: S1, weighing the followingraw materials in parts by weight: perchloroethylene resin, polystyrene, nano zinc oxide, modified magnalium hydrotalcite, a lubricant, a dispersing agent, an antioxidant and vinyl silanes; S2, mixingthe perchloroethylene resin, the polystyrene, the nano zinc oxide, the modified magnalium hydrotalcite, the lubricant, the dispersing agent, the antioxidant and the vinyl silanes, stirring, heating,and keeping stirring to obtain a mixture; and S3, placing the mixture in a preheated mold, and cooling to obtain the product. The modified magnalium hydrotalcite comprises the following raw materials:magnalium hydrotalcite, citric acid, beta-tarine sodium, a titanate coupling agent, an ethanol solution and distilled water. The prepared plastic product is excellent in mechanical property and heatresistance, the stretching, bending and impact strength and the thermal stability are remarkably improved, and the service life is prolonged effectively.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a method for preparing heat-resistant plastic products. Background technique [0002] Plastic products are a general term for daily necessities and industrial products processed with plastic as the main raw material, including products of all processes such as injection molding and blistering with plastic as raw material. Plastic is a kind of synthetic polymer material with plasticity. It, synthetic rubber and synthetic fiber form the three major synthetic materials that are indispensable in today's daily life. Compared with metal, stone, and wood, plastic products have the advantages of low cost and strong plasticity, and are widely used in the national economy. The plastics industry occupies an extremely important position in the world today. Over the years, the production of plastic products has developed at a high speed all over the world. . However, the current plastic ma...
