Abstract
The invention relates to a vehicle wheel hub and specifically relates to an aluminum alloy wheel hub with coatings on double sides. The aluminum alloy wheel hub is provided with an aluminum alloy wheel hub body. The aluminum alloy wheel hub is characterized that a high-temperature resistance insulation bottom coating and an abrasion-resisting decoration surface layer are arranged at two sides of the wheel hub body respectively in order. The high-temperature resistance insulation bottom coating is composed of epoxy polyester powder coating, methyl methacrylate-acrylic ester copolymerization coating and polybutadiene. The abrasion-resisting decoration surface layer is a polyurethane crylic acid photo-curing layer. The invention has the advantages of environmental protection, energy conservation, cost reduction, bright surface, good abrasion resistance and hardness damage for impact.
Description
Technical field
The present invention relates to automotive hub, the aluminium alloy wheel hub of the double-coating of specifically a kind of environmental protection and energy saving, cost-cutting, top layer light.
Background technology
As everyone knows, aluminium alloy wheel hub is owing to have in light weight, load-carrying capacity is strong, decorative surface is good, rapid heat dissipation, wear-resisting, advantage such as anti-corrosion, be widely used in miniature car, on motor bike and the Electrical Bicycle, the production method of aluminium alloy wheel hub is to adopt die casting and molding earlier now, carry out machinework again, carry out electroplating processes then, because electroplating processes complex process, energy consumption is big, but also consuming a large amount of nickel, copper, noble metals such as chromium are so the aluminium alloy wheel hub that prior art is produced has big for environment pollution, the consumption energy consumption water yield is big, the high deficiency of manufacturing cost.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, the aluminium alloy wheel hub of the double-coating of a kind of environmental protection and energy saving, cost-cutting, top layer light is provided.
The present invention can reach by following measure:
A kind of aluminium alloy wheel hub of double-coating is provided with the aluminium alloy wheel hub matrix, it is characterized in that wheel hub matrix both sides are respectively equipped with high-temperature insulation priming coat and wear-resisting finish coat successively.
High-temperature insulation priming coat of the present invention generally is made up of epoxy polyester powder coating, methyl methacrylate-acrylic ester copolymer coating and poly-butadiene.
Wear-resisting finish coat of the present invention is the polyurethane acroleic acid photocurable layers, makes the surface-brightening of wheel hub, resistance to abrasion good.
The present invention has that environmental protection and energy saving, cost-cutting, surface-brightening, resistance to abrasion are good, advantage such as be difficult for damaging.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further described:
As shown in the figure, a kind of aluminium alloy wheel hub of double-coating, be provided with aluminium alloy wheel hub matrix 1, wheel hub matrix 1 structure is same as the prior art, this does not give unnecessary details, the invention is characterized in that wheel hub matrix 1 both sides are respectively equipped with high-temperature insulation priming coat 2 and wear-resisting finish coat 3 successively, high-temperature insulation priming coat 2 is generally by the epoxy polyester powder coating, methyl methacrylate-acrylic ester copolymer coating and poly-butadiene are formed, wear-resisting finish coat 3 is the polyurethane acroleic acid photocurable layers, and the present invention has environmental protection and energy saving, cost-cutting, surface-brightening, resistance to abrasion is good, advantage such as be difficult for damaging.
