High-performance waterborne wood coating

Abstract

A high-performance waterborne wood coating is prepared from an organic silicon-acrylic emulsion and an additive. The additive comprises the following components by mass percentage: less than 5 percent of deionized water, 3 to 5 percent of film-forming additive, 0.1 to 1 percent of leveling agent, 0.1 to 0.5 percent of antifoaming agent, 0.1 to 0.2 percent of wetting agent, 0 to 0.1 percent of bactericide, 0 to 0.5 percent of thickener, and the balance of organic silicon-acrylic emulsion, wherein the organic silicon-acrylic emulsion is added with silica sol. The high-performance waterborne wood coating avoids the problems that most antifoaming agents have antifoaming and foam suppressing difficulties and that an excessive amount of the antifoaming agents leads to cavity shrinkage through the control of the addition amount of the antifoaming agent and improves the synthesis method of the emulsion. The organic silicon monomer and silica sol-containing high-performance waterborne wood coating emulsion with high solid content and low film forming temperature can reduce the film-forming temperature, be used for synthesis of low-viscosity and high-content waterborne wood coatings, improve the hardness of the waterborne wood coatings and improve the high-temperature resistance and after tack of the waterborne wood coatings.

Description

technical field [0001] The invention relates to a wood lacquer, in particular to a high-performance water-based wood varnish which is green and environmentally friendly, has excellent performance, low construction cost, and is safe and reliable. Background technique [0002] With the continuous advancement of society and technology, people are increasingly aware of the great harm that traditional solvent-based wood lacquers bring to people's lives. Because of the large amount of volatile solvents used in production and life, volatile organic compounds will be produced. (VOC), especially some benzene-containing organic substances, are easy to cause damage to human nerves, mucous membranes, skin and trachea, and even cause cancer. Therefore, water-based wood paints have emerged as the times require. However, because water-based wood lacquers are in the development stage, existing water-based wood lacquers still have problems such as low fullness, low hardness, heat resistance,...
