powder coating is a rapidly developing field in the entire coating technology. To realize the popularization and application of low-temperature powder coatings in automobile wheels, the premise is that the wheel products produced under the low-temperature powder process meet the current performance standards of automobile parts. Automobile wheels are the main load-bearing parts of automobiles, which not only require sufficient mechanical strength, but also sufficient toughness to ensure impact resistance.

However, the curing conditions of ordinary powder coatings are mostly around 180℃, and some are as high as 200℃, and the time is about 25min. First, the realization mechanism of low-temperature curing of low-temperature powders is analyzed; second, the baking of the two powders is tested Characteristics, the baking curve is drawn; third,hybrid epoxy polyester powder coating Factory  the mechanical performance test (yield strength and reliability test) and paint film test (adhesion, gravel impact, water resistance, salt spray test and balance weight sticking test) of the sprayed hub ; Afterwards, analyze and evaluate the application and promotion of low-temperature technology in the production of aluminum wheels.

Powder coatings have long been used on automobile wheels, and their environmentally friendly construction and excellent coating properties have promoted their rapid development in the auto parts industry in recent years. Reducing the curing temperature of the powder coating can increase the toughness of the wheel hub, reduce the production energy consumption of the enterprise, and achieve the purpose of energy saving and environmental protection.

Therefore, if the aluminum wheel industry can use low-temperature curing powder, there will be a lot of room for improvement in energy conservation and environmental protection.. There are shortcomings of high baking temperature and long time, which leads to high energy consumption in practical applications and too high The curing temperature can also cause parts to become brittle
