Product coating method based on plastic or nylon products

Abstract

The invention discloses a coating method for products, including glasses, based on plastic or nylon products. The coating method includes the following steps that the products are prepared and subjected to ultrasonic degreasing cleaning, ultrasonic deoiling cleaning and ultrasonic pure water cleaning; the cleaned products are dried and placed into a vacuum machine for film coating; the interior of the vacuum machine is vacuumized, and bombardment cleaning is carried out through direct current magnetron sputtering or medium-frequency magnetron sputtering or multi-arc magnetron sputtering; and reaction gas required for coating forming is added according to needs, and a target is used for conducting target sputtering on the products to form coatings. According to the coating method, ultrasonic cleaning is additionally adopted, the products are treated before being coated, balanced contact at multiple angles can be achieved, and cleaning precision is improved; multiple types of magnetron sputtering are adopted for bombardment cleaning, the surfaces of the products can be effectively cleaned before coating, and thus the products can be combined with the coatings more effectively; and in the coating environment, inert gas is injected continuously to control the vacuum degree and add the gas required for coating, and thus the required coating effect of the coatings is achieved.

Description

technical field [0001] The invention relates to the field of coating, in particular to a method for coating plastic or nylon products. Background technique [0002] Due to the non-conductivity of plastic and nylon products, except for ABS material, it is impossible to plate metal layer or non-metal layer by water plating method, but water plating of ABS material is also very difficult, and the water plating pollution is large, and it cannot meet the needs. It has a variety of colors and appearance, and the wear resistance is also low. At the same time, the general water plating is easy to corrode for the salt perspiration caused by human sweating. Therefore, in the industry, especially eyeglass products, such as eyeglass frames and their spare parts, it is urgent to coat the products with metal or non-metal coatings, and have a variety of appearance and color, wear resistance, bending resistance, corrosion resistance, and metal Surface treatment with strong texture and deco...
