Problems solved by technology

These body paints are mainly prepared for the outer shell of the car, but as the paint for the chassis, they are often ignored by those skilled in the art. In fact, the paint for the chassis is directly in contact with the soil and puddles on the ground, so it is more likely to be corroded. In addition, the maintenance of the chassis is relatively expensive, therefore, developing a coating for an anti-rust and anti-corrosion chassis has always been a technical problem to be solved by those skilled in the art

Abstract

The invention relates to the field of automobile anti-corrosion materials, in particular to a heat-preservation, heat-insulation, anti-rust and anti-corrosion coating for an automobile chassis, which is prepared by the following steps: step 1, adding 3-6 parts of nano silicon dioxide, 1-2 parts of dispersing agent and 10-15 parts of deionized water, and stirring and uniformly dispersing under high-speed mechanical stirring; the rotating speed of the high-speed mechanical stirring is 1,800 to 2,000 rpm (revolutions per minute); step 2, adding 50-70 parts of acrylic acid modified alkyd resin and 30-40 parts of epoxy resin into the uniform material obtained in the step 1, stably heating the working temperature to 50 + / -5 DEG C, and uniformly stirring at the rotating speed of 600-800rpm; 3, after the mixture in the step 2 is cooled to the room temperature, 0.5-1 part of composite magnesium aluminum silicate and 1-2 parts of dodecanol ester alcohol are added, and the mixture is evenly mixed at the room temperature. According to the paint, the acrylic acid modified alkyd resin and the epoxy resin are used as substrates, the nano silicon dioxide is added for combined use, and the paint adopts multi-component substances for combined use, so that the paint has the functions of heat preservation, heat insulation, rust prevention and corrosion prevention.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, and relates to automobile anti-corrosion materials, in particular to a thermal insulation, heat-insulation, rust-proof and anti-corrosion coating for vehicle chassis. Background technique [0002] With the development of technology and economy, automobiles have become very popular. While people pay attention to the brand of automobiles, they also pay attention to the quality of the automobile itself. The quality of the car depends on the decoration of the car interior and the quality of the car body. The quality of the car body is directly facing the public. Therefore, for the quality, people pay attention to the quality of the car body. The quality of the car body mainly refers to the decoration of the car body, that is, the choice of car body paint. [0003] Body paint is mainly divided into basic car paint, metallic paint and pearl paint. These body paints are mainly prepared for ...
