Problems solved by technology
[0002] As we all know, aluminum alloy wheels have been widely used in small cars, motorcycles and electric bicycles due to their light weight, strong bearing capacity, good surface decoration, fast heat dissipation, wear resistance, and corrosion resistance. The production method is to adopt mold casting to shape first, then carry out machining, and then carry out electroplating treatment. Due to the complicated electroplating treatment process, high energy consumption, and still consuming a large amount of precious metals such as nickel, copper, chromium, etc., the existing technology produces Aluminum alloy wheels have the disadvantages of large environmental pollution, large energy consumption and water consumption, and high manufacturing costs.

Embodiment Construction
[0010] The present invention will be further described below in conjunction with accompanying drawing:
[0011] As shown in the figure, a double-sided coated aluminum alloy wheel is provided with an aluminum alloy wheel base 1. The structure of the wheel base 1 is the same as that of the prior art. The high temperature resistant insulating primer layer 2 and the wear-resistant finish layer 3 are respectively provided. The high temperature resistant insulating primer layer 2 is generally composed of epoxy polyester powder coating, methyl methacrylate-acrylate copolymer coating and polybutylene dibutylene The wear-resistant finish layer 3 is a polyurethane acrylic light-cured layer. The invention has the advantages of environmental protection, energy saving, cost reduction, bright surface, good wear resistance, and not easy to be scratched.
