Problems solved by technology

[0002] When the road surface environment is relatively bad, the car is easily impacted by flying stones or sundries when driving. At this time, the coating on the body can protect it from being damaged by the impact of foreign objects, but the general coating will be damaged by the impact after a period of use. while the damage peels off

Abstract

The invention discloses a water-based chipping resistant coating for automobiles. The water-based chipping resistant coating comprises following raw materials, by mass: 180 to 190 portions of styrene-acrylic acid-2-ethylhexyl-acrylic acid polymer, 9 to 12 portions of heavy calcium carbonate, 10 to 15 portions of silicon carbide micro powder, 0.9 to 1.8 portions of sodium hexametaphosphate, 10 to 15 portions of 2-butoxyethanol, 1 to 5 portions of dimethylaminoethanol, 30 to 38 portions of aluminium triphosphate, 0.5 to 1 portion of polyoxyethylene octylphenol ether and 18 to 25 portions of deionized water, wherein the solid content of styrene-acrylic acid-2-ethylhexyl-acrylic acid polymer is 45 to 50%, and the particle size of silicon carbide micro powder is 1200 meshes. Adhesive force of the water-based chipping resistant coating on metal is high, and the level of adhesive force is grade 1 when the temperature is 30 or -30 DEG C; chipping resistance of the water-based chipping resistant coating is excellent, and the level of chipping resistance is grade 1; the level of the appearance of the water-based chipping resistant coating is grade 2; the water-based chipping resistant coating can be used for automobile outer metal plate, mudapron, front fender, and the like, and is suitable for air spraying.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a water-based chipping-resistant coating for automobiles. Background technique [0002] When the road surface environment is relatively bad, the car is easily impacted by flying stones or sundries when driving. At this time, the coating on the body can protect it from being damaged by the impact of foreign objects, but the general coating will be damaged by the impact after a period of use. And the damage peels off. [0003] To sum up, how to overcome the deficiencies of the prior art has become an urgent problem to be solved in the field of coatings. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and propose a water-based chipping-resistant coating for automobiles. The invention has good chipping-resistant effect, good adhesion to metal, excellent anti-rust performance and excellent appearance of the paint film....
