Problems solved by technology

However, there are still many problems in water-based paints. With water as a dispersant, due to the high latent heat of evaporation of water, a higher temperature and a longer time are required for drying; water-soluble paints contain lower molecular weight and a large amount of hydrophilic group, which will reduce the water resistance of the coating film

Abstract

The invention discloses waterborne wood paint which comprises, by weight, 40-60 parts of organosilicone modified acrylic microemulsion, 2-6 parts of defoamer, 1-5 parts of associated polyurethane thickener, 5-10 parts of menthol, 15-25 parts of butyl acrylate, 20-30 parts of urethane, 2-6 parts of wear-resistant aid, 5-10 parts of pigment, 3-8 parts of curing accelerator and 2-5 parts of flattingagent. The invention further discloses a preparation method of the waterborne wood paint. Adopted materials are environment-friendly, surface smoothness of the waterborne wood paint can be improved, water resistance and solvent resistance can be enhanced, glossiness can be improved, and adhesion resistance and damage resistance can be improved. By adopting special aids and proper proportion and through mutual coordination, the obtained waterborne wood paint forms a smooth and compact hydrophobic film on the surface, comprehensive performances like glossiness, water resistance and wear resistance of the waterborne wood paint are improved substantially, and the waterborne wood pain has excellent water resistance and glossiness especially.

Description

technical field [0001] The invention relates to the technical field of water-based wood lacquer, in particular to a water-based wood varnish and a preparation method thereof. Background technique [0002] In recent years, the situation of environmental pollution has become increasingly serious, and the national environmental protection standards for coatings have become more and more stringent. The replacement of traditional paints with water-based paints has been favored by customers and manufacturers. Water-based paint is green and environmentally friendly, uses water as a diluent, does not use harmful organic solvents, has little harm to the human body, and does not endanger the health of production and construction personnel. However, there are still many problems in water-based paints. With water as a dispersant, due to the high latent heat of evaporation of water, a higher temperature and a longer time are required for drying; water-soluble paints contain lower molecul...
