Abstract

The invention discloses a transparent primer for solid wood furniture and a preparation method thereof. The transparent primer comprises the following raw materials by weight: 50-70 parts of alkyd resin, 3-15 parts of modified resin, 5-15 parts of crystal filling powder, 3-15 parts of an inorganic transparent filler, 15-20 parts of a solvent, 0.1-2.0 parts of a wetting dispersant, and 0.05-0.3 parts of a leveling agent. The transparent primer prepared by taking two-component high-solid-content low-viscosity polyurethane as a main film-forming substance and adding the filler has the advantages of good filling property, no deformation, no hollowing, no collapse and high transparency, and provides an excellent bridging effect for furniture coating. The alkyd resin with high solid content and low viscosity is used for filling wood conduits or holes, and organosilicon modified alkyd resin is used as an auxiliary material, so that the good permeability of the paint liquid and the anchoring effect on wood fibers can be ensured.

Description

technical field [0001] The invention relates to a transparent primer for solid wood furniture and a preparation method thereof. Background technique [0002] Solid wood furniture is furniture made of raw wood, which has a natural beauty, is durable, and is easy to inherit. The vessels of natural wood are complex, of varying shades, and difficult to fill. During the use of finished furniture, there is a dynamic process of shrinkage and expansion with climate change, and the coating is prone to sagging or cracking, which affects the appearance. [0003] The traditional preparation method of transparent primer is to use alkyd resin plus isocyanate as the film-forming substance, together with talcum powder or transparent powder as the filler skeleton. If the amount is too large, the transparency of the paint film will be affected, and if the amount is too small, the filling will not be enough. After the logs are cooked and dried, the gums, fats, waxes, etc. rich in wood fibers...
