Car chassis bottom surface integrated powder paint and construction process thereof

Abstract

The invention discloses car chassis bottom surface integrated powder paint. The paint comprises the following components in parts by weight: 55 to 70 parts of polyester resin, 20 to 30 parts of epoxyresin, 4 to 6 parts of organic pigments, 0.5 to 1 part of inorganic pigments, 2 to 8 parts of mica powder, 5 to 10 parts of rutile titanium dioxide, 0.5 to 1.5 parts of hardening wax powder, 5 to 15 parts of barium sulfate, 0.5 to 1 part of a dispersing agent, 0.5 to 1 part of a flatting agent, 0.5 to 1 part of a defoaming agent and 0.5 to 1 part of an anti-ultraviolet absorbent. The constructionprocess comprises the following steps: S1, preprocessing a car chassis; S2, spraying the paint onto the car chassis by utilizing an electrostatic spraying gun; and S3, baking the car chassis sprayed in step S2 at a high temperature, wherein the baking temperature is 180 to 200 DEG C, and the baking time is 20 to 30 minutes.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an integrated powder coating for the underside of an automobile chassis and a construction process thereof. Background technique [0002] The automobile industry is the pillar industry of our country. The automobile industry is the largest demand market for protective and decorative coatings, and it is also one of the largest users of coatings. At present, the car chassis is generally sprayed with anti-corrosion paint. After the surface of the car chassis is cleaned, the primer needs to be baked first, and the second coat is sprayed after the primer is completely dry. High, it is easy to cause sagging or uneven thickness. Traditional paint contains a lot of organic solvents, which will cause certain harm to the body of operators during the construction process. There are irritating gas emissions that pollute the air, and the actual product utilization rate is only between 50-70...
