Embodiment 1

[0065] The substrate is made of mobile phone 3D glass, and the method of back spraying is adopted. The gradient color spraying process includes the following steps:

[0066] (1) Spray high-transparency blue paint, spray the entire surface first, and then reduce 1 / 2 of the sprayed area in turn for 2 layers of spraying. The thickness of the paint sprayed each time is 3 μm, thus forming a high-transparency from deep to shallow Blue effect, then put it in an oven to dry at 150°C for 5 minutes, and form a high-transparent blue paint layer after surface drying. Wherein, in parts by weight, the high transparency blue paint contains 40 parts of acrylic resin, 10 parts of blue color paste with a particle size of 200nm, and 50 parts of mixed solvent.

[0067] (2) Spray purple red to golden yellow chameleon paint, spray the whole surface of purple red to golden yellow chameleon paint on the surface of the high-transparent blue paint layer, the thickness of the sprayed paint is 6 μm, then...

Embodiment 2

[0072] The substrate is made of PC plastic board, which is sprayed on the back. The gradient color spraying process includes the following steps:

[0073](1) Spray high-transparency red paint, spray the entire surface first, and then reduce 1 / 2 of the sprayed area in turn for 2 layers of spraying. The thickness of the paint sprayed each time is 4 μm, thus forming a high-transparency from deep to shallow. Red effect, then put it in an oven to dry at 150°C for 5 minutes, and form a high-transparency red paint layer after surface drying. Wherein, in parts by weight, the highly transparent red paint contains 30 parts of polyester resin, 20 parts of red color paste with a particle size of 250nm, and 50 parts of mixed solvent.

[0074] (2) Spray the yellow-green chameleon paint, spray the whole surface of the yellow-green chameleon paint on the surface of the high-transparency red paint layer, the thickness of the sprayed paint is 7 μm, then put it in an oven and dry it at 150°C for...

Embodiment 3

[0079] The base material is a stainless steel thermos cup, which is sprayed on the front. The gradient color spraying process includes the following steps:

[0080] (1) Spray bright black paint, then spray the entire surface of bright black paint on the front of the substrate, the thickness of the sprayed paint is 10 μm, and then put it in an oven to dry at 150°C for 5 minutes, and form a bright black paint layer after surface drying. Wherein, by weight, the bright black paint contains 68 parts of acrylic resin, 22 parts of carbon black powder with a particle size of 7 μm, and 10 parts of mixed solvent.

[0081] (2) Spray the red-to-gold chameleon paint, spray the red-to-gold chameleon paint on the surface of the bright black paint layer, the thickness of the sprayed paint is 7 μm, and then put it in an oven and dry it at 150°C for 5 minutes, and form after surface drying Layers of chameleon paint. The red-to-gold chameleon paint contains 75 parts of polyester resin, 10 parts...

Abstract

The invention discloses a gradient color spraying process. The gradient color spraying process comprises the following steps of: providing a substrate, color change paint and color transparent paint,wherein the substrate has a front side and a back side which are opposite; spraying the color change paint and the color transparent paint onto the front side or the back side of the substrate, and drying to form a color change paint layer and a color transparent paint layer, wherein the color transparent paint layer and the color change paint layer are sequentially arranged in the direction far away from the front side of the substrate. According to the technical scheme, the gradient color spraying process can solve the problem in the related art that the special-angle color change effect ofthe gradient color is not obvious.

Description

technical field [0001] The invention relates to the technical field of spraying technology, in particular to a gradual color spraying process. Background technique [0002] In the related art, the gradient color effects generally realized by spraying process are usually blue to purple, blue to green, blue to black, green to black, red to blue, or various light effects. The color changes from dark to light. However, when viewed from different viewing angles, the colors of these gradients are fixed, that is, the color changing effect of gradient colors is less obvious. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide a gradient color spraying process, aiming at solving the problem in the related art that the different-angle discoloration effect of the ...
