Description

Technical Field

[0001] The utility model relates to the field of wood paint structures, in particular to an environment-friendly closed primer coating with good sealing performance. Background Technique

[0002] The wood paint structure refers to the structure of a layer of paint coated on a wooden object. For example, the utility model patent with the publication number CN206139458U discloses an environment-friendly furniture water-based two-component wood paint coating structure, including a UV open clear topcoat layer coated on the surface of a furniture substrate, an organosilicon polymer-modified polyacrylate waterproof coating is arranged on the surface of the UV open clear topcoat layer, a white latex layer is arranged on the surface of the one-component polyurethane waterproof coating layer, an artemisia juice gel layer is arranged on the surface of the white latex layer, a metal cross-linked molecular film-forming two-component water-based wood paint layer is arranged on the surface of the artemisia juice gel layer, and an anti-oxidation layer is arranged on the surface of the metal cross-linked molecular film-forming two-component water-based wood paint layer.

[0003] Most woods contain tannic acid. Tannic acid is an organic compound, its powder is yellow or brown, and it is easily soluble in water and very easy to migrate from the wood to the surface of the coating. If the closed primer cannot effectively seal the tannic acid in the wood, the coating is very easy to turn yellow. At the same time, most woods are very easy to absorb water and expand, and are very easy to get swollen wood fibers when encountering water, resulting in unevenness during painting. At the same time, as the water volatilizes, the swollen wood fibers shrink back, which will cause the collapse of the paint film. In addition, due to the thin paint surface, it is easy to crack later, which is not beautiful and the organic solvent components in the primer are exposed, which is not friendly to the environment. Therefore, improvements are needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an environment-friendly closed primer coating with good sealing performance, and solve the problems of low strength and non-environment-friendliness of the existing wood paint structure.

[0006] Preferably, the sealing inhibitor layer is a sealing anti-alkali primer. Through the arrangement of the sealing inhibitor layer, the tannic acid in the wood base layer body can be sealed in the wood.

[0007] Preferably, both the lower putty layer and the upper putty layer are unsaturated polyester resin putties. Through the arrangement of the lower putty layer and the upper putty layer, the flatness of the wood base layer can be increased.
