Waterborne clear priming paint for woodenware and preparation method thereof

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...

[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 The sanding property of the paint, the commonly used sanding aid is zinc stearate powder or slurry substance, the addition of sanding aid will cause problems of poor transparency and poor stability
