Abstract

The invention discloses an anti-collapse high-filling water-based woodware transparent primer. The transparent primer is prepared from a component A, a component B and water. The component A is prepared from the following raw materials in parts by weight: 65 to 80 parts of water-based hydroxy acrylic resin, 0.2 to 0.8 part of a wetting agent, 0.2 to 1 part of a dispersing agent, 0.2 to 0.6 part of a defoaming agent, 0.4 to 1 part of transparent powder, 1 to 2 parts of polishing powder, 6 to 10 parts of a coalescing agent, 0.1 to 0.2 part of a flatting agent, 3 to 5 parts of anti-settling slurry, 3 to 5 parts of water and 0.2 to 0.6 part of a thickening agent; the component B is a curing agent; the weight ratio of the component A to the component B to the water is 100: 20: (10-20). the formula primer provided by the invention not only can ensure the mirror surface sealing effect of a paint film after spraying, but also can ensure the transparency and non-collapse of the paint film, has the characteristics of good transparency, collapse resistance, good filling property, easiness in polishing and the like, and is suitable for the coating requirements of different furniture and wooden products, especially high-grade mirror surface sealing effect.

Description

technical field [0001] The invention relates to the field of wood coatings, in particular to an anti-collapse high-filling water-based wood transparent primer and a preparation method thereof. Background technique [0002] Due to the environmental protection characteristics of water-based paint, its application range is becoming wider and wider. However, the general water-based transparent primer has low solid content and insufficient compactness of the paint film, resulting in poor collapse resistance and poor filling performance, especially for applications with deep catheters. Wood, such as ash, white ash, oak, oak, walnut, mahogany, Sapele and other woods, after spraying, the surface of the paint film is flat and has a mirror effect. After only a few months of installation, the paint film collapsed at the catheter, and there were strips of collapse marks, resulting in extremely poor mirror effects and seriously affecting the popularization and application of water-based ...
