Abstract

The invention discloses a vehicle environment-friendly wear-resistant paint. The vehicle environment-friendly wear-resistant paint is prepared from, by weight, 50 to 60 parts of modified polyester resin, 2.5 to 3 parts of a wear-resistant filler, 1 to 1.5 parts of a lubricating filler, 1 to 1.6 parts of a curing agent, 0.2 to 0.3 part of an antifoaming agent, 0.3 to 0.4 part of an anti-settling agent, 0.2 to 0.3 part of a leveling agent, 0.1 to 0.2 part of an UV absorber, 5 to 8 parts of styrene, and 40 to 50 parts of N,N-dimethyl formamide. The invention also discloses a preparation method ofthe paint. According to the preparation method, modified polyester resin with excellent water resistance, wear resistance, and impact resistance is taken as a paint film forming matrix; the wear-resistant filler is added, so that the wear-resistant filler is preferably dispersed in the resin matrix for bearing and load dispersing effect, and is capable of improving paint wear resistance through forming of more compact inorganic / organic coating layers with the resin; the obtained paint possesses excellent wear resistance and water resistance, and is capable of satisfying vehicle production line spraying technology requirements.

Description

technical field [0001] The invention belongs to the technical field of automobile coating, and in particular relates to an environmentally friendly and wear-resistant coating for automobiles and a preparation method thereof. Background technique [0002] When the car is running, its wheel covers, floor panels, side beams, fenders and door pedals are easily impacted by sand and stones, which can easily damage these parts and lead to corrosion, thus bringing hidden dangers to driving. Therefore, it is very important and necessary to protect these parts of the car, and the commonly used protection method is to coat these parts with wear-resistant paint. [0003] Existing coatings have the following disadvantages: they are not resistant to high temperatures, and will crack, blister, and fall off after being exposed to the hot sun for a long time; they have poor waterproof performance and are easily penetrated by rainwater, resulting in internal corrosion; If the force is poor, ...
