Abstract

The invention belongs to the technical field of decorative plates for decoration and finishing, and discloses a coating process of a matte veneer. The coating process comprises the following steps: (1) cleaning a base material, coating putty paint in a roller mode, and carrying out UV drying and curing; (2) frosting the dried and cured base material, carrying out dust removal, coating UV sanding primer, and carrying out UV drying and curing; (3) keeping coating the UV sanding primer, carrying out UV drying and curing, and carrying out frosting after curing to obtain a semi-finished product plate; and (4) removing dust of the semi-finished product plate, coating UV matte finish paint in a roller mode, enabling the semi-finished product plate to enter a super-matte machine for matte treatment, and carrying out UV drying and curing to obtain the matte veneer, wherein the condition parameters of the super-matte machine are as follows: the nitrogen inlet pressure is 4-7 bar, the nitrogen purity is greater than or equal to 99%, and the temperature is 20-50 DEG C. According to the coating process, the super-matte machine is adopted for production, so that the matte degree of the matte veneer is 0.5-5, and the matte veneer has the advantages of being anti-pollution, convenient to clean, fingerprint-proof, scratch-resistant, repairable and odorless.

Description

technical field [0001] The invention belongs to the technical field of decorative boards for decoration, in particular to a coating process for matte decorative boards. Background technique [0002] At present, the coating effects of matte and matte veneers in the industry are divided into matte and high-gloss, and wood paint is divided into matte, semi-gloss and high-gloss according to the gloss. And matte paint is a kind of paint that is more commonly used in people's life. It has a wide range of applications, but most consumers are not very clear about the characteristics and application range of matte paint. However, the existing coating process scheme can only achieve a minimum of 30.0 degrees and 50.0 degrees for the matte effect, and after spraying the matte topcoat, it needs to be left to dry. There are two steps in the drying process: the first step It is surface dry, that is, it has reached the surface gel state. After reaching this state, if some dust, thread end...
