Problems solved by technology

[0004] The technical problem to be solved by the present invention: for the organic solvent method commonly used at present can not completely remove wax scale, wax removal rate is slow, wax removal effect is poor, especially impossible to effectively clean away the metal oxides on the surface of metal workpieces, Carbide and other polishing materials, the organic solvent contained is not only highly toxic, but also may be hydrolyzed. In a humid environment, it will corrode metal workpieces. An environmentally friendly wax remover and its preparation method are provided.

Abstract

The invention relates to an environment-friendly wax removal agent and a preparation method thereof, and belongs to the technical field of surface treatment. According to the environment-friendly waxremoval agent and the preparation method thereof, hexamethyldisilazane is adopted to conduct surface modification on diatomaceous earth, the oleophylic property of the diatomaceous earth is improved,a methyl group successfully replaces a hydroxyl group, the numbers of hydrophilic silicon hydroxyl groups are decreased, the density of electron clouds around silicon atoms is increased, the shieldingeffect is enhanced, and binding energy of the silicon atoms and oxygen atoms is reduced; and the property of particle adsorption wax is enhanced by the modified methyl group, meanwhile, the diatomaceous earth can serve as inorganic cleaning particles, in the wiping process with the surface of workpieces, the wax is removed through friction and the adsorption effect, paraffin thirsty bacteria cultured and clustered on the surface of the diatomaceous earth can effectively decompose the wax and synergistically cooperates with oleinic acid to adsorb and dissolve an alcohol amine compound of stearic acid and the oleinic acid in polishing wax, wax scale is stripped out from a substrate, and the wax removal efficiency of materials is improved.

Description

technical field [0001] The invention relates to an environment-friendly wax remover and a preparation method thereof, belonging to the technical field of surface treatment. Background technique [0002] In recent years, with the continuous improvement of people's living standards and industrial technology, various metal products, electronics, precision industry and other products have been widely used in industrial production and people's daily life, and the market demand is also relatively large; various metal and Metal alloys have excellent physical and chemical properties and surface treatment characteristics, and are widely used. In order to improve their comprehensive performance, surface finish and decorative effect, surface finishing treatment must be carried out. Among them, mechanical polishing with special polishing wax is the first step in surface finishing treatment. Effective surface polishing process; for example, car glazing wax and polishing agent are used to...
