Problems solved by technology

[0002] Existing car coatings only play a decorative role in the car, and play a small protective role in the car. If the car is in contact with a hard object, the paint is easy to fall off, and the paint is easy to fall off when the branches are scraped. Wind and sand fall on it, and it is easy to accumulate The more, thus affecting the beauty of the car body
Moist air is easy to condense on the surface of the car, presenting a "water mist" appearance defect; in addition, the existing car surface still has the problem of low gloss, which affects the use effect and aesthetics

Abstract

The invention discloses a high-gloss low-haze sprayable protective paint for cars. The protective paint comprises a base film layer and functional layers which are arranged at the upper side and the lower side of the base film layer, and a raw material formula comprises the following components in parts by weight: 1000 to 1500 parts of low-boiling-point aliphatic hydrocarbon of C6 to C8, 1000 to 1300 parts of vinyl organic silicone resin, 1000 to 1500 parts of polyvinyl chloride resin, 800 to 1200 parts of metallocene linear low-density polyethylene, 1200 to 1800 parts of vinyl acetate-acrylic emulsion, 35 to 50 parts of docusate sodium, 10 to 20 parts of PVC resin, 50 to 80 parts of nano aluminium oxide, 60 to 90 parts of fumed silica, and 30 to 60 parts of ammonium ethoxylated alkyl sulfate. According to the protective paint provided by the invention, the haze is less than or equal to 1.0 percent, and the gloss is greater than or equal to 90 percent. The nano aluminum oxide can reduce the surface coarseness of a coating surface coated by the paint, and various components are in synergistically action to enable the paint to have the performance of high gloss.

Description

technical field [0001] The invention relates to a high-gloss and low-haze sprayable automotive protective paint and a preparation method thereof. Background technique [0002] Existing car coatings only play a decorative role in the car, and play a small protective role in the car. If the car is in contact with a hard object, the paint is easy to fall off, and the paint is easy to fall off when the branches are scraped. Wind and sand fall on it, and it is easy to accumulate The more, thus affecting the beauty of the car body. Moist air is easy to condense on the surface of the car, showing "water mist" appearance defects; in addition, the existing car surface still has the problem of low gloss, which affects the use effect and aesthetics. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a high-gloss and low-haze sprayable protective coating for vehicles and a preparation method t...
