Abstract

The invention discloses antirust coating for a mechanical device. The antirust coating is prepared from the following raw materials in parts by weight: 20 to 30 parts of phenolic resin, 15 to 25 partsof epoxy resin, 10 to 20 parts of silicone acrylic emulsion, 4 to 8 parts of tetraethylammonium tetrafluoroborate, 2 to 3 parts of cellulose acetate, 3 to 6 parts of dibutyl phthalate, 2 to 5 parts of strontium chromate, 3 to 9 parts of rosin, 2 to 4 parts of iron oxide, 1 to 3 parts of nano silver, 2 to 7 parts of modified bamboo powder, 1 to 4 parts of dispersing agent, 2 to 4 parts of thickening agent, 3 to 5 parts of stabilizer, and 15 to 25 parts of deionized water. By controlling the original types and proportion, the prepared antirust coating is low in cost, good in heat dissipation performance, excellent in heat resistance and salt resistance, and capable of effectively prolonging the service life of the machinery.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to an antirust coating for mechanical equipment and a preparation method thereof. Background technique [0002] The rust prevention of mechanical equipment has always been a problem that needs to be paid attention to in the process of industrial production and use. Mechanical equipment mostly uses steel as the material. The main matrix component of steel is iron. Iron is a very active element that is easily oxidized in humid air to form iron oxides. Once oxidized, it not only affects the appearance, but also may seriously affect the function of the product. The anti-corrosion ability of iron element in saline environment is also very unoptimistic. The main cause of corrosion is the pitting effect of chloride ions. In practice, the oxidation of iron and the corrosion of salt often work together, so that the corrosion resistance of steel is very poor. This ...
