Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.

[0019] see figure 1 , a two-color wheel hub spraying method, comprising the following steps:

[0020] The first step, black paint blending: use banana water as a diluent to blend acrylic matte black paint, and use a flow cup to check the viscosity of acrylic matte black for 10-12 seconds;

[0021] The second step, black paint spraying: use a spray gun to use compressed air to spray the blended acrylic matte black paint to the set thickness to the part where the black paint is to be sprayed on the wheel hub, that is, the spoke part of the motorcycle wheel hub;

[0022] The third step, paint drying: heat and dry the hub until the black paint film is completely dry;

[0023] The fourth step is the processing of the red paint spraying part: the part of the wheel hub that is to be sprayed ...

Abstract

The invention discloses a method for spraying double-color hubs. The method includes black paint blending: blending acrylic acid matted black or bright black paint with diluents until a viscosity value of a flow cup ranges from 10 seconds to 20 seconds; black paint spraying: spraying the blended acrylic acid matted black or bright black paint to portions, where the black paint needs to be sprayed, of a hub until a set thickness requirement is met; paint drying: heating and drying the hub until black paint films are thoroughly dried; red paint sprayed portion machining: cutting and machining portions, where red paint needs to be sprayed, of the hub until a natural color of a base of the hub is completely exposed; red paint blending: blending acrylic acid transparent red paint by diluents until a viscosity value of a flow cup is 15 seconds; red paint spraying: directly spraying the blended acrylic acid transparent red paint to the portions, where the red paint needs to be sprayed, of the hub until a set thickness requirement is met; drying: heating and drying the hub until red paint films are thoroughly dried. The method has the advantages that shielding measures are omitted when the second colored paint is sprayed to the hub, accordingly, the double-color hub spraying production efficiency is high, and the production cost is low.

Description

technical field [0001] The invention relates to a paint spraying method, in particular to a two-color wheel hub spraying method for motorcycles. Background technique [0002] Existing motorcycle wheel hubs are usually made of cast aluminum alloys, and their exposed surfaces all need to be sprayed with protective paint. For ordinary grade motorcycles, its exposed surfaces usually only need to be painted with a single color of paint. However, for higher-grade, high-end or export motorcycle products, it is often necessary to spray two different colors in different areas to form two-color wheels, thereby beautifying the appearance of the wheels and improving the grade of motorcycles. The two-color spraying method in the prior art is to cover or not cover the area sprayed with another color when spraying the first color. When choosing not to cover, after the first color is sprayed, it can be processed by mechanical processing or chemical stripping, etc. The method is to remove ...
