Abstract

The invention relates to a preparation method of antioxidative decontaminable polishing paste and belongs to the technical field of polishing. According to the invention, polyphenol organic matter isextracted from highland barley and sorghum, the polyphenol compound can capture hydroxyl radical to form a new organic component and eliminate hydroxyl radical and prevent its oxidizability; and highland barley and sorghum also have other organic components, and free radical can be captured through deoxyribose to generate malonaldehyde; and titanium element is also introduced. Through chelating metal ions, activity of the organic component is promoted, and the antioxidative effect of the polishing paste is enhanced. In the invention, tetrabutyl titanate is used as a raw material to generate nanoscale titanium dioxide particles, titanium dioxide is highly dispersed in the polyphenol compound and other organic compounds such that titanium dioxide and the organic components are fully contacted; and through photocatalysis effect of titanium dioxide, electron transition is formed in large quantity on the surface of the polishing paste during illumination of the polishing paste, and oil stain on the surface is decomposed so as to achieve the decontamination effect. The polishing paste of the invention has a wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of an anti-oxidation and decontamination polishing paste, which belongs to the technical field of polishing. Background technique [0002] Polishing paste is an abrasive containing various ingredients, which is used in the process of polishing objects. It is an abrasive with properties similar to soap for polishing metal, plastic handicraft, resin, imitation porcelain melamine, wood lacquer and other products. [0003] It is made from two parts of oil and powder according to the scientific ratio. When in use, the polishing paste must be wiped evenly along the direction of the rotation of the polishing wheel, and then the workpiece to be thrown is brought to do a parabolic motion with the polishing wheel. [0004] Commonly used polishing processes are divided into: rough polishing: generally used with yellow polishing paste and cloth sticky grinding wheel, which is the first polishing process, the purpose ...
