Abstract

The invention discloses a coating and glazing process for inorganic decorative sheets and a preparation method of coatings. The coating and glazing process and the coatings are mainly used for protecting and decorating coatings formed in early coating stage of the inorganic decorative sheets. Compared with traditional spraying, brush coating and roller coating processes, the coating and glazing process has the advantages of high production efficiency, good paint film build, high yield and low coating waste rate; the coatings for the coating and glazing process include a UV spray coating, a water spray coating and a fluorine-modified PU spray coating, and formed coating and glazing paint is good in water resistance, pollution resistance, ageing resistance and scrub resistance.

Description

technical field [0001] The invention belongs to the field of coating technology and new paint materials. In particular, it relates to the coating decoration and protection of inorganic plates for architectural decoration. Background technique [0002] In recent years, with the country's policy advocacy and industrial support for renewable low-carbon materials, inorganic decorative panels have emerged as a new type of reusable and renewable energy-saving and environmentally friendly new material. Inorganic decorative panels have played an important market role in replacing the original metal, plastic, and wooden decorative panels. [0003] With the market promotion and use of inorganic decorative panels, there is a wider demand for the appearance, performance and other characteristics of inorganic decorative panels. Commercially available inorganic decorative panels are mainly divided into indoor and outdoor use, and the requirements for coating performance are also differe...
