Abstract

The invention discloses a waterborne clear priming paint for woodenware and a preparation method thereof. The waterborne clear priming paint is composed of the following components by weight: 35-50% of a waterborne acrylic core-shell-structured emulsion, 40-60% of a waterborne metal cross-linked acrylic emulsion, 3-10% of deionized water, 0.1-0.5% of an antifoaming agent, 1-3% a film-forming aid,0.1-0.5% of a substrate wetting agent and 0.1-0.5% of a thickening agent. Since the waterborne acrylic core-shell-structured emulsion is compounded with the waterborne metal cross-linked acrylic emulsion, the waterborne clear priming paint of the invention has the following advantages: 1, the film forming temperature of compounded resin is lowered, the addition amount of the film-forming aid is reduced, a formed coating has a fast-drying characteristic and excellent sanding properties, a polishing aid is not needed, and the transparency and stability of the waterborne clear priming paint are ensured; and 2, the waterborne clear priming paint has sealing features and can prevent a paint film from yellowing.

Description

technical field [0001] The invention belongs to the technical field of water-based paint, and in particular relates to a water-based wood clear primer and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of coating technology and the requirements of national environmental protection regulations, water-based wood coatings have been accepted by more and more people due to their low energy consumption and low pollution. [0003] However, some characteristics of water-based wood coatings restrict the rapid development of water-based wood coatings, especially the sandability and transparency of water-based wood primers. Generally, before spraying the water-based wood clear primer, it is necessary to spray a water-based sealing primer to seal the oil and tannin of the wood to prevent the yellowing of the paint film, and the general water-based wood clear primer needs to be added with grinding aids to ensure For the sanda...
