Water-based white primer for bamboo-wood ware product

Abstract

The embodiment of the invention discloses a water-based white primer for a bamboo-wood ware product. The water-based white primer is used for effectively sealing a flavone pigment in a bamboo-wood substrate and solving the problem that a coating becomes yellow after being dried due to the fact that the flavone pigment infiltrates into the coating; the water-based white primer is low in volatile organic compound content, and has environmental protection property, good rubbing property, covering ability and anti-mildew and anti-corrosion properties. The water-based white primer is prepared from the following raw materials in parts by weight: 30-40 parts of water-based acrylic resin, 10-20 parts of water-based polyurethane resin, 0.5-7.5 parts of a coalescing agent, 0.1-1 part of a dispersing agent, 0.1-0.5 part of a base material wetting agent, 0.1-1 part of an antifoaming agent, 0.1-0.5 part of a bactericide, 0.1-1 part of a preservative, 0.1-0.5 part of a pH modifier, 10-20 parts of titanium dioxide, 10-15 parts of calcium carbonate, 0.1-0.5 part of nanometer aluminum oxide, 5-10 parts of an inorganic filler, 0.1-0.5 part of a thickener and 5-15 parts of water.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a water-based white primer for bamboo and wood products. Background technique [0002] As we all know, because the bamboo wood substrate contains flavonoid pigments, it is easy to induce yellowing of the water-based white paint used for bamboo and wood products on the market, thereby affecting its coating effect. Generally speaking, natural flavonoids mostly exist in the form of glycosides, and due to the different types, quantities, joint positions and joint methods of sugars, various flavonoid glycosides can be formed. At the same time, because the mother nucleus of flavonoids A cross-conjugated system can be formed inside, and the conjugated chain can be extended through electron transfer and rearrangement, so the bamboo wood substrate can show a variety of different natural colors, but because flavonoid glycosides are generally soluble in water, resulting in water-b...

Problems solved by technology

[0004] The embodiment of the present invention provides a water-based white primer for bamboo and wood products, which can effectively seal the flavonoid pigments in the bamboo and wood substrates, and prevent the flavonoid pigments from bleeding into the coating to cause the coating to turn yellow after drying. Moreover, the water-based white primer has low organic volatile content, is environmentally friendly, and has good sanding properties, hiding power, anti-mildew and anti-corrosion properties
