Abstract

The invention belongs to the technical field of aluminum alloy door and window spray-coating, and particularly discloses a spray-coating method of an aluminum alloy door and window. The method includes the steps of preprocessing, degreasing, deoiling, neutralizing, electrochemical polishing, anodizing, spray-coating and curing. The completeness of the surface of a non-spray-coated aluminum alloy profile can be improved, the smoothness of the surface of a anodized aluminum profile is improved, and therefore the airtightness of a coating is improved, the decoration performance and corrosion resistance of the aluminum alloy profile are enhanced, the spray-coating quality is improved, and the machining quality of the aluminum alloy profile is improved.

Description

technical field [0001] The invention relates to the related fields of aluminum alloy doors and windows, in particular to a spraying method for aluminum alloy doors and windows. Background technique [0002] Aluminum alloy is an alloy composed of aluminum as a matrix element and one or more alloying elements. Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Especially with the hot expansion of the real estate industry, aluminum alloy profiles have become an important form of exterior wall and interior enclosure in current buildings, reflecting the new concept of modern architecture. [0003] Most of the existing aluminum alloy surface treatment before spraying is not in place, and there are still small pits or cracks on the aluminum alloy surface, which leads to uneven surface after passivation treatment of the alu...
