and selectively printing a second plasticizer on the surface color layer corresponding to the pattern to expose part of the base material.

Specifically, the coating method of the imitated marble pattern can be applied to various base materials, and the base materials can be porous and loose base materials (such as wood, putty base surfaces and the like) or compact base materials (such as PVC plates and the like). To porous, loose substrates.

For dense base materials, a spray gun can be adopted to directly spray the base color on the base materials through a dry spraying method, and a brush pen can also be adopted to directly draw the base color on the base materials.

When the base color is directly sprayed on the base material by adopting a dry spraying method, the depth of the color can be adjusted by adjusting the spraying frequency.

Aiming at porous and loose base materials, the base materials can be leveled and densified by spraying solid color priming paint for multiple times, and the spraying frequency is preferably 1-5 times. The base color can then be applied to the solid primer layer by dry-spraying using a spray gun, or drawn on the solid primer layer using a brush.

The solid color primer layer is selected from PU solid color primer or water-based 2K PU solid color primer. And spraying the solid color primer on the base material to form the solid color primer layer. It will be appreciated that the substrate with the solid primer layer may also be sanded, preferably with a grit number greater than 800 grit.

The first molding agent can dissolve the resin in the ground color layer, so that the ground color layer presents a preset pattern.

When the surface color layer is formed, the surface color can be directly sprayed on the base color layer presenting the preset pattern by a spray gun through a dry spraying method.

When the surface color is directly sprayed on the base color layer presenting the preset pattern, the color depth can be adjusted by adjusting the spraying times.

The raw material of the surface color layer contains color paste of a special model, namely temacolor series color paste, and when the second molding agent is used for selectively printing and pressing a specific area, the surface color layer in the peripheral area is not easy to generate the phenomena of flowering and edge accumulation.
