A kind of metal, plastic, wood automatic coating method

Abstract

The present invention relates to the field of coating technology, specifically an automatic coating method for metals, plastics, and wood. The method also includes the following steps: cleaning the workpiece to be coated with a high-pressure water gun; wrapping the cleaned workpiece Textured film; spray the workpiece wrapped with the textured film with fluid silica gel; dry the workpiece sprayed with silica gel at high temperature, after drying, the silica gel solidifies into a solid, and remove it together with the textured film; put the processed workpiece into the automatic coating In the equipment, the coating is completed through two coating and scraping processes; the coated workpiece is dried; the coating is dried; the coated workpiece is placed at a constant temperature of 20‑30 degrees Celsius, and the humidity Store in an environment between 20%-30%; store at the required temperature and humidity to prevent the workpiece from getting wet or rust; to ensure that there will be no uneven coating or coating caused by residual impurities or moisture on the surface of the workpiece Problems with bubbles.

Description

technical field [0001] The invention relates to the field of coating technology, in particular to an automatic coating method for metal, plastic and wood. Background technique [0002] Coating refers to the products made of metal, plastic, wood and other materials, and the surface is covered with a protective layer or decorative layer. Coating is an important link in the surface manufacturing process. Anti-rust, anti-corrosion, aesthetics, and the disadvantage of changing the material itself is that the coating quality is one of the important aspects of the overall quality of the product. [0003] The coating method in the prior art is to first wash the workpiece to be coated with clean water, then dry it to remove impurities on the surface of the workpiece, use equipment or manually to coat the workpiece, and finally dry it, but the clean water cannot Complete removal of surface impurities will leave residual impurities and incompletely dried moisture, which will directly ...
