Water-based automobile chassis paint with strong permeation adhesiveness

Abstract

The invention discloses a water-based automobile chassis paint with strong permeation adhesiveness. The water-based anti-rust paint is prepared from the following raw materials: a water-based epoxy ester resin dispersion, dimethylethanolamine, deionized water, polyether polyol, alkynediol, modified polysiloxane, montmorillonite, a coloring pigment, an anti-rust pigment, sericite, barium sulfate, a water-based polyester modified epoxy resin dispersion, a drier, a gold anti-flash-rust auxiliary agent, a wetting leveling agent, a rheological auxiliary agent and a cosolvent. The water-based automobile chassis paint disclosed by the invention has relatively high anti-sagging performance and leveling property; has good constructability, and can adapt to manipulator and manual spraying under different seasonal environmental conditions; and has better corrosion resistance, and can reduce the maintenance cost of the vehicle can be reduced.

Description

technical field

[0001] The invention relates to the technical field of automobile chassis paint, in particular to a water-based automobile chassis paint with strong penetration and adhesion. Background technique

[0002] The chassis of the car, as the weight-bearing part of the car, is located at the bottom of the car body. When the car is running at high speed, the road sand and gravel will impact and wash the lower part of the car body floor, damaging the coating on the surface of the part. In order to prolong the service life of the car body, improve the comfort of the car and the corrosion resistance between the car body gaps, add 1-2 mm thick coating on the lower surface of the car body (especially the surface of the wheel cover and fender that is easily hit by stones) Anti-rust coatings with stone chip resistance are the most effective method.

[0003] At present, the armor coatings for automobile chassis are mainly based on asphalt and synthetic rubber products. Bit...
