A polishing agent used for automobiles and a preparing method thereof

Abstract

A polishing agent used for automobiles is disclosed. The polishing agent is prepared from, by weight, 8-15 parts of citric acid, 10-20 parts of glacial acetic acid, 5-10 parts of cinnamic acid, 5-12 parts of salicylic acid, 20-50 parts of glycerol, 30-80 parts of polyethylene glycol 8000, 100-200 parts of divalent acid ester, 2-8 parts of polyoxyethylene oleyl ether, 5-12 parts of nanometer titanium dioxide, 3-5 parts of nanometer silica, 5-9 parts of nanometer zinc oxide and 20-30 parts of an auxiliary agent. The citric acid, the glacial acetic acid, the cinnamic acid and the salicylic acid which are diacids and low in corrosion are adopted to replace strong acids and strong alkalis and are dissolved into the divalent acid ester, and therefore oxides on the surface of automobile paint can be rapidly cleaned. The nanometer titanium dioxide, the nanometer silica and the nanometer zinc oxide can increase surface adhesion force of the polishing agent and improve activity of the polishing agent. Through cooperation of the auxiliary agent, paint surfaces can be rapidly polished through friction and a protection film is formed on the surface layer of the paint.

Description

technical field [0001] The invention relates to the field of surface technology, in particular to a polishing agent for automobiles and a preparation method thereof. Background technique [0002] With the development of science and technology, automobiles have become an indispensable means of transportation in people's lives. Due to the usual collision or scratching of automobiles, the surface of the car paint will be rough. At the same time, automobiles are often exposed to the sun and rain. The paint will fall off, wear or be corroded, which will also cause the surface of the car paint to be rough; for car paint polishing is the key to solving this problem, generally polishing is to process the surface of the workpiece to make it highly smooth. The main purpose of car polishing is to remove slight oxides and impurities on the surface of the paint layer, and to fill up the fine defects on the surface of the paint film by chemical cutting. The polishing agents on the market ...

Problems solved by technology

The main purpose of car polishing is to remove slight oxides and impurities on the surface of the paint layer, and to fill up the fine defects on the surface of the paint film by chemical cutting. The polishing agents on the market now mainly contain solvents with strong solubility, which are generally toxic Strong, highly corrosive, and harmful to the human body
