A kind of special transparent primer for solid wood and preparation method thereof

Abstract

The invention discloses a special real wood transparent primer and a preparation method thereof. The special real wood transparent primer consists of a component A, a component B and a component C, wherein the component A is a transparent primer prepared from two special saturated polyester resin and epoxy resin together with auxiliary raw materials such as a proper amount of talcum powder; the component B is prepared from butyl acetate, a polyisocyanate curing agent, and the like; the component C is prepared from butyl acetate, propylene glycol methyl ether acetate, dimethyl carbonate, xyleneand the like; and when being used, the component A, the component B and the component C are uniformly mixed according to a ratio, and are applied to the surface of high-class real wood furniture to form a coating layer. Tests and actual use effects show that the coating layer not only is good in adhesion property, good in flexibility, high in hardness and good in transparency, but also has the properties of rib reinforcement, filling performance, sinking prevention and capability of revealing natural textures (clarity and stereoscopic impression) of wood, and is capable of greatly improving the texture and the grade of real wood furniture.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a special transparent primer for solid wood and a preparation method thereof. Background technique [0002] At present, in the home furnishing industry, PE / UV transparent primers and PU topcoats are mostly used for closed coating of solid wood furniture, but the products produced by this process show that the wood grain is not clear and natural, the three-dimensional sense of layering is poor, and the color is also very poor. Rigid, not as fresh as pure PU primer, it cannot improve the grade of solid wood furniture. [0003] PU transparent primer is a kind of wood coating with excellent comprehensive performance, which is widely used in wood decoration. However, after the construction of conventional PU transparent primer, due to the characteristics of ordinary alkyd resin, the degree of crosslinking cannot be designed too high, and the hardness is not high. It is easy to penet...

[0002] At present, in the home furnishing industry, PE / UV transparent primers and PU topcoats are mostly used for closed coating of solid wood furniture, but the products produced by this process show that the wood grain is not clear and natural, the three-dimensional sense of layering is poor, and the color is also very poor.

[0003] PU transparent primer is a kind of wood coating with excellent comprehensive performance, which is widely used in wood decoration. However, after the construction of conventional PU transparent primer, due to the characteristics of ordinary alkyd resin, the degree of crosslinking cannot be designed too high, and the hardness is not high. It is easy to penetrate into the paint film, and the paint film shrinks severely after drying. During the multi-coating (closed type) process of solid wood substrates, the solvent of the subsequent coating penetrates into the water, causing the paint film in the wood grain conduit to swell and bulge, and the paint film dries out. Subsidence or bulge of the posterior wooden eye (cannot be retracted) thus affecting the surface effect
