Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The present invention provides an embodiment of a method for making a gradient coating, please refer to figure 1 As shown, a schematic diagram of its main flow is shown. In this embodiment, the method includes the following steps:

[0043] S1. According to the geometric size of the area to be sprayed, evenly divide the area to be sprayed into several strip-shaped areas.

[0044] Specifically, the substrate can be the outer surfaces of objects such as automobiles, hardware, electronic products, home appliances, equipment, and construction engineering objects. The areas to be sprayed on these outer surfaces may be fla...

Abstract

The invention provides a manufacturing method of a gradient coating. The method comprises the following steps: a to-be-sprayed area is uniformly divided into multiple strip-shaped areas according to the geometric dimension of the to-be-sprayed area; a stepping reference line and a stepping distance are set, and a spraying direction is set; starting from the stepping reference line, colored paint is sprayed in the spraying direction, the spraying length is defined by the colored paint crossing k strip-shaped areas, when color paint is sprayed for one time, one stepping distance is stepped forward along the stepping reference line, the color paint is sprayed for the next time, and the spraying length is defined by the colored paint crossing k strip-shaped areas; and n colored paints with different color concentrations are sequentially sprayed on the to-be-sprayed area according to a color concentration increasing or decreasing sequence, wherein each colored paint is sprayed for m times, n is equal to or larger than 2, m is equal to or larger than 3, and k is equal to or larger than 3. The coating formed by the manufacturing method comprises multiple transition color strip-shaped areas, each transition color strip-shaped area is formed by splicing two colors, and the areas of the two colors are gradually increased or decreased in one direction in the gradient color area to form smooth transition.

Description

technical field [0001] The invention belongs to the technical field of spraying, in particular to a method for making a gradient coating. Background technique [0002] When painting the exterior of a car, a gradient color spraying process is sometimes used, that is, a gradient color is sprayed on the exterior of the car. However, in the prior art, various spraying methods are required to be sprayed into gradient colors, such as thick spray, heavy spray, large gun spray, etc., to obtain dark color effects, but there are deficiencies in this existing spraying technology. Specifically, thin spray, thin spray, and small gun spray are used to obtain a light-colored effect, and it is difficult to obtain a smooth transition gradient effect, and the construction is complicated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for producing a gradient coating, aiming at solving the problem that the existing conve...
