Problems solved by technology

[0004] Anodized products will inevitably cause appearance defects in the process of daily operation or assembly and disassembly, which will affect their appearance, and then cause the product to be scrapped. The conventional repair technology is to remove the film and re-plate the product. Repair, that is, remove the oxide film through acid-base chemical reaction, then perform chemical and mechanical polishing, and then re-anodize the surface of the product. In this way, firstly, the anodic oxidation itself pollutes the environment greatly, and secondly, the size of the product will change. Larger deviation, the third is that the processing cost more than doubles

Embodiment Construction

[0030] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0031] Preparation of abrasives, including the following mass components made in proportion:

[0032] Aluminum oxide 15-40%, water 15-40%, glycerin 7-20%, silicon oxide 6-12%, rosin 2-5%, petroleum spirit 7-13%, acid-treated light distillate 5-10% , white mineral oil 1-5%, aluminum silicate fiber 2-5%, ethylbenzene 0-0.1%, carbon black 0-0.1%.

[0033] The aluminum oxide, silicon oxide and aluminum silicate fibers are all nanoscale materials.

[0034] A kind of anodic oxidation appearance defect repair process:

[0035] Step 1, use a sponge wheel to evenly spread the abrasive to the entire surface of the anodized part with appearance defects, and then let it stand for at least 1 minute;

[0036] The sponge wheel can be configured on the trajectory planning system to realize continuous automatic operation of anodized parts. The trajectory planning system can be...

Abstract

The invention provides an anodic oxidation appearance defect repairing process and an abrasive material thereof, the abrasive material prepared from components such as aluminum oxide, silicon oxide, rosin and aluminum silicate fiber is used for repairing and polishing an anodic oxidation appearance defect part, a compact protective layer is formed in an anodic oxidation piece pore and a defect groove, and the anodic oxidation appearance defect is repaired and polished. A workpiece filled with the grinding material is high in durability, the filling performance in a high-temperature, high-pressure and high-humidity environment is still stable, meanwhile, the defect repairing effect is excellent, and the characteristics of a product cannot be modified.

Description

[0001] Technical field [0002] The invention relates to the technical field of repairing aluminum or aluminum alloy anodic oxidation layers and surface dyed layers, in particular, a process for repairing anodic oxidation appearance defects (scratches, scratches, crushing, etc.) and related abrasives. Background technique [0003] Anodizing and dyeing are a kind of decoration technology widely used in aluminum surface treatment. This technology can not only improve the corrosion resistance and light resistance of aluminum and aluminum alloy products, but also beautify the appearance, obtain colorful decorative effects, and increase the additional value of products. value. [0004] Anodized products will inevitably cause appearance defects in the process of daily operation or assembly and disassembly, which will affect their appearance, and then cause the product to be scrapped. The conventional repair technology is to remove the film and re-plate the product. Repair, that is,...
