Problems solved by technology

Generally, a polishing machine is used for polishing. Since the polishing wheel is in direct contact with the surface of the plastic product, it is prone to over-polishing or insufficient polishing.
Excessive polishing will directly affect the appearance of the product and waste raw materials, while insufficient polishing will increase the scrap rate, thereby increasing input costs

Abstract

The invention discloses a polishing paste for modifying and processing a plastic product, and relates to the technical field of processing a plastic product. The polishing paste is prepared from the following raw materials, by weight: 80-90 parts of modified bentonite, 30-35 parts of soap powder, 25-30 parts of zeolite powder, 15-20 parts of fly ash, 15-20 parts of rape seed cake powder, 13-18 parts of tea seed powder, 12-16 parts of tung oil, 10-15 parts of modified microcrystalline wax, 8-12 parts of active carbon, 8-12 parts of silica powder, 6-10 parts of vaseline, 5-8 parts of tallow, 50-60 parts of ethanol, and 300-350 parts of water. According to the invention, the polishing paste for modifying and processing a plastic product is prepared by taking modified bentonite as a main raw material, and can be directly coat the surface of the plastic product. The polishing effect can be effectively improved; the dimension accuracy of the plastic product can be furthest protected; and over polishing is prevented.

Description

Technical field: [0001] The invention relates to the technical field of plastic product processing, in particular to a polishing paste for plastic product modification and processing. Background technique: [0002] Plastic products are a general term for daily necessities and industrial products processed with plastic as the main raw material. Including plastic as raw material for injection molding, blister and other products of all processes. The production of plastic products generally includes plastic ingredients, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic has been formed into finished products or semi-finished products, also known as plastic secondary processing. In the finishing process, it is necessary to remove cold scars, spots and trace waste edges on the surface of plastic products by polishing. Generally, a polishing machine is used for polishing. Since the polishing wheel is in direct conta...
