Abstract

The invention discloses a preparation method for a light-controlled color-changing colorful aluminum alloy wheel hub. The preparation method comprises the following concrete steps: preparing a modified filling material, then mixing acrylic resin, amino resin, epoxy resin and a diluent into a high-speed dispersing machine, carrying out mixing under stirring, then successively adding the above-mentioned prepared modified filling material, CAB381, an anti-settling wax 229, a leveling agent, a color-changing photosensitizer and butyl ester, continuing stirring until uniform mixing is realized, andcarrying out grinding treatment in a three-roll grinder so as to prepare a coating; and polishing a motorcycle aluminum alloy wheel hub, carrying out cleaning and drying treatment, spraying a prepared coating onto the surface of the aluminum alloy wheel hub, then carrying out flash-drying at 100 DEG C, continuing spraying treatment, and carrying out baking at 150 DEG C for 3 to 5 min so as to prepare a light-controlled color-changing colorful motorcycle aluminum alloy wheel hub. The aluminum alloy wheel hub prepared by using the preparation method provided by the invention can automatically change colors with the change of illumination, and has good coating mechanical properties.

Description

Technical field: [0001] The invention relates to the field of alloy preparation, in particular to a method for preparing an optically controlled discoloration and colorful aluminum alloy wheel hub. Background technique: [0002] At present, in the traditional processing technology of aluminum alloy wheels of motorcycles, although the appearance colors are available in various colors, they are relatively single on the wheels. In order to meet individual requirements, several mixed coating processes of different colors have been developed in recent years, but none of them are truly novel and cannot meet the changing market demands of the younger generation in pursuit of fashion. [0003] Chinese patent (201610894865.6) discloses a high temperature resistant primer and its preparation method and application; solvents and thinners. The primer can be used for wheel hub coating, and can effectively cover defects such as depressions and sand marks on the hub; however, the primer ...
