a rust removal paste

Abstract

The invention relates to derusting slurry which contains 10-30wt% of aluminum oxide polishing powder, 1-3wt% of octadecyl triethoxy silane, 0.1-3wt% of stearic acid, 1-2wt% of glycerol, 0.1-1wt% of phosphoric acid, 0.1-1wt% of manganese dioxide, 0.1-0.5wt% of surfactant and the balance of water. According to the invention, the derusting slurry can remove iron rust on surfaces of iron devices, and can simultaneously form a protective film, thereby preventing the iron devices from rusting again.

Description

technical field [0001] The invention relates to a slurry for metal surface polishing. Background technique [0002] Iron devices will inevitably be oxidized to a certain extent during long-term contact with air, especially in humid environments, which will cause a layer of rust on the surface of the device. Although the existing rust removal treatment agent can remove the rust on the surface, the rust removal If the finished iron is not treated with anti-corrosion treatment, the surface will soon be oxidized again and lose its metallic luster, and even rust will regenerate. Contents of the invention [0003] The object of the present invention is to provide a rust removal slurry. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] A rust removal slurry, containing 10-30wt% alumina polishing powder, 1-3wt% octadecyltriethoxysilane, 0.1-3wt% stearic acid, 1-2wt% glycerin , 0.1-1wt% phosphoric acid, 0.1-...
