Abstract

The invention discloses an environment-friendly wear-resistant coating for automobiles, which is prepared from the following raw materials in parts by weight: 50-60 parts of modified polyester resin, 2.5-3 parts of wear-resistant filler, 1-1.5 parts of lubricating filler, and 1-1 part of curing agent 1.6 parts, 0.2-0.3 parts of defoaming agent, 0.3-0.4 parts of anti-settling agent, 0.2-0.3 parts of leveling agent, 0.1-0.2 parts of ultraviolet absorber, 5-8 parts of styrene, N,N-dimethyl formaldehyde 40-50 parts of amide; the invention also discloses the preparation method of the coating. The paint of the present invention adopts modified polyester resin as the film-forming matrix of the paint, and the modified polyester resin has good properties such as water resistance, wear resistance, and impact resistance; adding wear-resistant fillers, it can not only be better dispersed in the resin The matrix plays the role of bearing and dispersing the load, and can form a closer inorganic / organic coating with the resin to enhance the wear resistance of the coating; obtain a coating with excellent wear resistance and water resistance, which can meet the requirements of automobiles. Spraying process requirements on the production line.

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, ...
