Preparation method of automobile surface polishing agent

Abstract

The invention discloses a preparation method of an automobile surface polishing agent, belonging to the field of automobiles. The method comprises the following steps: preparing a chloroplatinic acid-isopropanol catalytic solution, dropwisely adding into alpha-decene to react, and carrying out reduced pressure distillation to obtain methyl long-chain alkylsiloxane; by using carnauba wax and beeswax as raw materials, adding the methyl long-chain alkylsiloxane and triethanolamine in the molten state to obtain a polishing agent semifinished product; and mixing the semifinished product with castor oil and anhydrous ethanol, and adding sodium dodecyl benzene sulfonate and sodium borate to obtain the automobile surface polishing agent. The polishing agent disclosed by the invention can enhance the brightness, has the advantages of rust and corrosion resistance, favorable stability, no toxicity or harm, convenient raw material sources, simple preparation technique and low production cost, is easy for wiping and suitable for daily automobile maintenance, and has industrial production value.

Description

technical field [0001] The invention discloses a preparation method of an automobile surface polishing agent, which belongs to the field of automobiles. Background technique [0002] The surface coating of the automobile body endows the automobile with a beautiful appearance and excellent protection performance, which can improve the use value of the automobile and prolong its service life. Because the environment in which a car is used as a means of transportation is very complicated, it not only has to withstand the tests of heat, cold, wind, sun, and rain, but also has to bear the damage of dust, exhaust gas, fuel, road asphalt, mud, and mechanical rubbing. It is said that the service life of the car coating can be close to the service life of the car under good maintenance and normal maintenance, and the car body coating can achieve a long-term decorative effect. [0003] The surface coating includes a colored topcoat layer and a clear varnish layer. The base resins use...

Problems solved by technology

[0008] The technical problem mainly solved by the present invention: Although the polished wax film can improve the brightness and luster of the automobile topcoat, it is difficult for almost all wax films to ensure the uniformity and durability of the coating. To solve the problem of repeated polishing, a preparation method of automobile surface polishing agent is provided. The present invention first prepares chloroplatinic acid-isopropanol catalytic solution and adds it dropwise in α-decene for reaction, and then decompresses after the reaction Distillation to obtain methyl long-chain alkyl siloxane, using carnauba wax and beeswax as raw materials, adding methyl long-chain alkyl siloxane and triethanolamine in a molten state to obtain a semi-finished polishing agent, and then mixing the semi-finished product with castor oil, Dehydrated alcohol is mixed, and adding sodium dodecylbenzenesulfonate and sodium tetraborate can make a kind of automobile surface polishing agent, and the polishing agent that the present invention makes has the anti-rust anti-corrosion of increasing brightness, good stability, The advantage of being easy to wipe, and the polishing agent is non-toxic and harmless, the source of raw materials for preparation is convenient, the preparation process is simple, and the production cost is low. It is suitable for daily car maintenance and has industrial production value.
