Technical Field

The invention belongs to the technical field of decorative plates for decoration, and particularly relates to a coating process of a matte decorative plate.

Background

At present, the coating effect of the matte and matte decorative board in the industry is divided into matte and highlight, and the wood paint is divided into matte, semi-gloss and highlight according to the glossiness. The matte paint is a paint which is commonly used in people's life, and the application range is very wide, but most consumers do not clearly determine the characteristics and the application range of the matte paint. The existing coating process scheme can only achieve the minimum matte effect of 30.0 degrees and 50.0 degrees, and after the matte finish paint is sprayed, the coating process needs to be kept stand for drying, and the process of drying comprises two steps: the first step is surface drying, namely, the surface gelation state is achieved, the final effect of the paint is generally not influenced if some dust, thread ends or small particles fall on the paint surface after the surface is achieved, and the paint can sink into the paint if fine substances such as dust floating in the air fall on the paint surface before the surface drying is not achieved, so that the final effect of the paint is greatly influenced, if the surface is not smooth due to protrusion, the matte effect of the paint is further influenced, the second step is a real drying stage, namely, volatile thinner in the paint is completely volatilized, simultaneously the A component and the B component of the two-component paint generate a three-dimensional cross-linking chemical reaction, a complete three-dimensional net structure is achieved, and at the moment, the paint achieves equivalent surface hardness and can be used as a product. The problems that can be generated by the current technology are as follows: the surface effect is not good, particle impurities are easy to form, and the matte effect is not good. And the ultra-matte skin-feel matte coating effect is required to be achieved in the furniture and customized home decoration industries.
