Abstract

The invention relates to the field of mechanical processing protective coatings, and discloses a mechanical processing anti-acid corrosion coating. Hydrophobic agent, deionized water, acrylonitrile, vanadium diboride, tributyl phosphate, polyvinyl alcohol and polysilicone, by using the inherent chemical properties and porosity of the organic membrane itself, using water as the carrier, with the help of water penetration The effect reacts with the acidic substances outside the organic diaphragm, and acts along or against the direction of water pressure, so as to achieve the purpose of waterproof, moisture-proof, and chemical corrosion resistance, and solve the problem that the existing protective coating is corroded by the acidic environment, which causes mechanical surface damage. Exposure to the external environment reduces its service life.

Description

technical field [0001] The invention relates to the field of mechanical processing protective coatings, in particular to a mechanical processing anti-acid corrosion coating. Background technique [0002] In the existing mechanical processing, when the finished product is completed, it is necessary to coat the exterior with paint. The main purpose of this paint is to isolate the humid environment from the metal surface of the machine and reduce the risk of corrosion on the machine surface. However, in actual use, conventional paint can only be used Isolate the general humid environment. As carbon dioxide emissions exceed the standard, there is a certain amount of acid rain in all major, medium and small cities. Although conventional coatings can isolate the humid environment, as the droplets adsorbed on the surface of the machine dry, the concentration of the acidic liquid increases. The surface of the paint is corroded, causing the mechanical surface to be exposed to the ext...
