Problems solved by technology

[0004] After a comprehensive study of the existing technology, it is found that the following problems still exist: 1. The existing polishing agent can only grind and polish the car paint surface, and there is still a certain color difference with the original paint at the scratched paint surface after completion , cannot be repaired to a higher degree; 2. After polishing, the brightness and color do not match the original paint, and the gloss and brightness are unsatisfactory; 3. The matching polishing equipment cannot realize the function of manually adjusting the intensity and stabilizing the polishing , it is troublesome to replace the polishing agent, and needs further improvement

Abstract

The invention discloses an automobile paint surface polishing agent and a preparation method thereof, and relates to the technical field of automobile paint surface processing. The polishing agent isprepared from hydrophobic repairing abrasive, a surfactant (fatty alcohol polyoxyethylene ether), an oil remover (dimethyl silicone oil), an excipient (sodium alginate), an aqueous thickening agent (potassium sorbate), a composite brightener, and a diluent prepared by mixing a plurality of solvents. The raw materials are mixed and stirred, and then the mixture is subjected to vacuum defoaming to obtain the polishing agent. After the polishing agent is painted on an automobile paint surface, the paint surface is fully grinded, a compact protective film is formed, the repairing performance is good, the automobile paint surface has good glossiness and brightness, and the color difference between processed paint surface and the original paint surface is small. A polishing device, which can beused to artificially adjust the force of spraying the polishing agent, is adopted; a foldable airbag, which is safe and is convenient to replace, is used to store the polishing agent; and the polishing quality and polishing speed are largely improved.

Description

technical field [0001] The invention relates to the technical field of automobile paint surface treatment, in particular to an automobile paint surface polishing agent and a preparation method thereof. Background technique [0002] Car polishing is mainly to remove slight oxides and sundries on the surface of the paint layer, use polishing abrasives and fill in the fine defects on the surface of the paint film by cutting, so as to achieve functions such as dewaxing, elimination of paint surface defects, and chemical transformation. Polishing agents can be divided into common type and general type according to the scope of use, and can be divided into physical cutting type, chemical cutting type and comprehensive cutting type according to the cutting method. Among them, the ordinary type is mainly used to control the paint film defects such as oxidation, scratches, and fading in different degrees of ordinary paint; the general type can be used for both ordinary paint and tran...
