Abstract

The invention relates to the field of industrial coatings, and especially relates to an anti-ultraviolet vehicle paint and a preparation method thereof. The anti-ultraviolet vehicle paint is preparedfrom a water-based hydroxyl polyacrylic acid dispersion, a pH neutralizer, a coalescing agent, deionized water, polytetrafluoroethylene micro-powder, a benzotriazole ultraviolet light absorber, titanium dioxide, a flame retardant, pigment, barium sulfate, bentonite, a thickener, a water-based polyurethane curing agent, propylene glycol diacetate, a dispersing agent, an antifoaming agent, a wettingleveling agent and an antibacterial agent. The vehicle paint has the advantages of favorable ultraviolet resistance, favorable gloss, favorable decorativeness, favorable hydrophobicity, low VOC, lowodor and environment friendliness.

Description

technical field [0001] The invention relates to the field of industrial coatings, in particular to an anti-ultraviolet car paint and a preparation method thereof. Background technique [0002] Ultraviolet rays have high energy, which can destroy the composition of organic matter and accelerate its aging. Therefore, it can cause discoloration and loss of light in traditional automotive paints under sunlight. Structural changes are prone to occur after high-energy ultraviolet irradiation, which will still reduce its anti-ultraviolet ability, making it difficult to maintain gloss and color for a long time, and prevent the aging of the paint film, and will release certain toxic substances as the additives degrade. On the other hand, traditional automotive paints not only have high VOC content and are harmful to the environment, but are also generally not resistant to high temperatures. Under sunlight, they may emit a pungent odor due to high temperatures, and even burn in severe...
