Embodiment 1

[0044] refer to figure 1 , a surface coloring method of a vehicle wheel, the surface coloring method comprising the following steps:

[0045] (1), first carry out surface treatment on the vehicle wheel, the wheel surface has a background color;

[0046] (2), and then spray a layer of peelable paint on the surface with the base color;

[0047] (3) After drying, peel off the strippable paint in the pattern area where the color needs to be changed;

[0048] (4), spray another layer of paint of another color;

[0049] (5) After drying, peel off the peelable paint except the pattern area to complete the color registration.

[0050] Explain as follows: The pattern area refers to the area that needs to be colored on the surface of the wheel according to the design. It can contain one picture, two pictures or even multiple pictures. Different pictures can be spaced from each other or overlapped (overlapping will cause color If the paint overlaps, it will produce a mixed color effe...

example 2

[0066] Example 2: if figure 1 The rim shown is sprayed with paint according to the normal process, and the process is as follows: pretreatment → powder spraying and drying → spraying silver white paint surface drying or drying → spraying varnish or transparent powder and drying. Pick out qualified products, spray them with perchlorethylene peelable paint, dry them by themselves or dry them, and cut them along with 3D laser cutting equipment. figure 1 Cut the contour line of area 2 to the bottom varnish layer, peel off the peelable paint attached to area 2, and then spray a layer of black polyester amino paint, peel off the rest of the peelable paint after the surface is dry, and then dry at high temperature Later, two-color wheels are available. It is also ok to peel off the rest of the peelable paint after drying at high temperature.

example 3

[0067] Example 3: if figure 2 The rim shown is sprayed with paint according to the normal process, and the process is as follows: pre-treatment → powder spraying and drying → spraying white plain paint and drying → pre-treatment after the three-car project → spraying varnish or transparent powder and drying. Pick out qualified products, spray nitrocellulose peelable paint, surface dry or dry at low temperature, and use three-dimensional laser cutting equipment to cut figure 2 Cut the contour line of area 3 to the bottom varnish layer, peel off the strippable paint attached to area 3, and then spray a layer of blue alkyd amino paint, peel off the rest of the strippable paint after the surface is dry, and then dry Finally, a three-color rim with the bright color of the car in area 2, blue in area 3, and white in area 4 can be obtained. It is also ok to peel off the rest of the peelable paint after drying at high temperature.

Abstract

The invention provides a surface color processing method for vehicle wheels. The method comprises the following steps: (1)carrying out surface process on the vehicle wheels firstly, wherein the surface of the wheel is provided with underpainting; (2) spraying a layer of strippable paint on the surface with the underpainting; (3) drying and then peeling off the strippable paint of the pattern area needing to change the color; (4) spraying a layer of colored paint of another color; and (5) drying and then peeling off the strippable paint of the area except the pattern area, and finishing the color processing. The invention also provides the wheels manufactured by the color processing method. The invention provides the wheels with even interface of different colors and excellent appearance; and the surface color processing method for the wheels provided by the invention has simple process and reduced process cost.

Description

technical field [0001] The invention relates to a manufacturing process of a vehicle wheel, in particular to a method for coloring the surface of a vehicle wheel and the wheel. Background technique [0002] At present, there is generally only one color of wheels on the market, and the common methods are as follows: the color of the paint presented by the full coating, the mirror metal color presented by vacuum plating and water electroplating. With the changes in people's aesthetics and individual needs, the requirements for wheel surface decoration are also getting higher and higher. [0003] If it is necessary to present two different colors on the surface of the wheel, the common method is the three-car engineering, that is, the normal fully-painted wheel is machined on a lathe to cut off the paint on the A side to expose the silvery white of the aluminum alloy itself, and then paint it on. It is made by applying a layer of protective varnish; or dispensing, that is, lea...
