Abstract

The invention provides a plastic surface treatment process, which comprises the following steps: degreasing, coarsening, surface neutralization, surface catalysis, making a liquid wear layer, oxidation flame treatment, vacuum treatment, washing and drying. The process provided by the invention can make the plastic surface soften by degreasing, coarsening, neutralizing, catalyzing and oxidation flame-treating the plastic, the liquid wear layer is sprayed to the plastic surface under vacuum condition, and the sprayed plastic is dried, so that a plastic surface layer with a wear-resistant function is generated on the plastic surface, the wear-resistant function of the plastic surface is effectively improved by the formed plastic surface layer, and the wear resistance of the plastic is effectively improved. By adopting the process, the surface layer with the wear-resistant function is more effectively attached to the plastic surface, and is combined with the matter in the plastic, so that the wear-resistant layer is more effectively combined with the plastic surface, and thus the wear resistance of the plastic is effectively enhanced, and the service safety and stability of the plastic are improved.

Description

technical field [0001] The invention belongs to the field of plastic processing, and in particular relates to a plastic surface treatment process. Background technique [0002] Plastic is a polymer compound made of monomer as raw material through addition polymerization or polycondensation reaction. Because plastic itself has the advantages of low cost, strong plasticity, light material, good insulation, and low thermal conductivity, it can be directly processed into living materials. , Industrial and other supplies. When the plastic is used in a running workpiece, the surface of the plastic will be subject to friction, which will cause the casting on the plastic surface to wear and fall off, and the life of the plastic will have a certain impact. [0003] Therefore, how to improve the wear resistance of plastics is a research subject for those skilled in the art. Contents of the invention [0004] In order to solve the above problems, the invention discloses a plastic s...
