[0005] CN 109401598 A discloses an antifouling self-repairing coating and its preparation method. The coating achieves the purpose of antifouling self-repairing by adding self-cleaning resin and flexible resin, reducing surface energy and reducing paint film hardness, but the paint film hardness is low , is also not suitable for axles, and the coating of this invention needs to be cured by heating
[0006] In order to meet the industry's demand for high-quality coatings, all kinds of self-healing polyaspartic ester coatings have poor temperature and wear resistance and are not suitable for axle protection

Abstract

A self-repairing heat-resistant and wear-resistant polyaspartic ester coating and its preparation method, the coating is formed by mixing component A and component B according to the mass ratio of 2 to 4:1: the A component It contains polyaspartic acid resin, amino-terminated silicone, coloring pigment, filler, dispersant, ultraviolet light absorber, ultraviolet light stabilizer, anti-settling agent, leveling agent, defoamer and solvent; the B group Contains isocyanate, polysulfide modified epoxy resin, diluent. The invention also includes a preparation method of the self-repairing temperature-resistant and wear-resistant polyaspartic acid ester coating. The coating of the present invention has a high solid content, is environmentally friendly, and has a one-time film-forming thickness of ≥ 80 μm; the drying speed of the construction coating film is fast and the construction efficiency is high; the coating film constructed by the coating of the present invention has good self-repairability, and the surface of the coating film is smooth. Excellent wear resistance and temperature resistance. The preparation method of the invention has simple process, low cost and is suitable for industrialized production.

Description

technical field [0001] The invention relates to a polyaspartic acid ester coating, in particular to a self-repairing heat-resistant and wear-resistant polyaspartic acid ester coating and a preparation method thereof. Background technique [0002] With the increasing environmental protection requirements, traditional fuel trucks tend to be gradually converted into electric trucks. The main difference between electric trucks and fuel trucks is that the power of electric trucks comes from the battery-driven motors directly installed in the axles. During operation, the temperature is above 120°C, and this high temperature will soon be transmitted to the axle. Because the axle chassis is relatively low from the ground, and the truck’s operating conditions are poor, the truck axle chassis needs to be sprayed with a layer of protective paint. The coating requires both durability and temperature resistance, and traditional axle protection coatings cannot meet the above two requireme...
