A kind of nano car paint film of composite material and its surface coating process

Abstract

The invention relates to a car paint film and a coating technique thereof, particularly a composite nano car paint film and a surface coating technique thereof. The car paint film solvent is composed of the following components in percentage by weight: 80% of solid polysiloxane resin, 15% of glass fiber and 5% of pure water. The glass fiber comprises 53% of silicon dioxide, 12% of aluminum oxide, 13% of calcium oxide, 11% of boron oxide, 6% of magnesium oxide and 5% of sodium oxide. The solid polysiloxane resin and glass fiber are blended with the pure water to obtain the car paint film solvent finished product. The coating technique comprises the following steps: cleaning the car body, and carrying out clay adsorption treatment; performing trimming protection, polishing the car paint, spreading a gloss recovery agent, cleaning the car body, and degreasing; and car film coating: adding a coating agent, spraying with a spray gun, standing the coating agent for 30 minutes, and cleaning. The material has high oxidation resistance; and the acidic substance permeability of common car paint is 25%, while the acidic substance permeability after applying the nano coating is lowered to 1-2%. The paint film successfully protects the car paint from damage by acid rain and other acidic substances under the condition that the car coating is not oxidized.

Description

technical field [0001] The invention relates to a car paint film and a coating process, in particular to a composite material nano car paint film and its surface coating process. Background technique [0002] Cars are often driven on the road, and after a period of time, they will lose their luster and the paint surface may also be damaged. The outer layer of modern car paint is also called transparent paint layer, which is only 0.05mm thick. It has a beautiful luster, but is very delicate. Ordinary car care waxing, polishing, and sealing glaze can increase the brightness to a certain extent, but it will bring side effects. Car wax itself is a soft substance and drains easily, which means that when the paint needs protection most, the wax has little effect. In addition, because any car wax contains silicon components, the car paint will be corroded by ultraviolet radiation for a long time, leaving some black spots, especially the abrasive particles in the car wax will f...

Problems solved by technology

Car wax and car glaze, which are not environmentally friendly and have a pungent smell, have "congenital defects", that is, the main component of car wax and car glaze is a kind of oxidized oil extracted from petroleum, which will make the car dirty after a long time. The surface of the lacquer becomes black and dark, and the freshness of some waxing is only a few days, and the freshness of the glaze is only a few months, and the damage to the transparent paint layer is greater when polishing. Generally, after three times of polishing, The clear paint layer will be removed, accelerating the aging of the car

In addition, polishing and sealing are easy to thin the car paint, because the sealing glaze needs to be polished and ground first, and then it needs to be sealed at least twice with a sealing machine. , it is easy to form deep swirl scratches and damage the car paint
