Problems solved by technology

However, the matte powder will float to the surface of the paint film during the drying process of the paint film, and the matte powder is soft, which affects the improvement of the scratch resistance performance. At the same time, the improvement of the scratch resistance performance by simply adding wax emulsion is limited

Abstract

The invention relates to waterborne woodware matte white finish with high scratch resistance and high performance. The finish is mainly prepared from the following raw materials (by weight): 55-70 parts of self-crosslinking waterborne pure acrylic resin, 0.1-0.2 part of a waterborne multifunction additive, 0.2-0.6 part of an aqueous dispersant, 0.2-0.4 part of a waterborne wetting agent, 16-22 parts of titanium dioxide, 3-6 parts of a coalescing agent, 0.5-1.5 parts of an antifreezing agent, 0.1-0.3 part of a water-based defoamer, 0.1-0.2 part of an anticorrosion and bactericidal agent, 0.4-1.2 parts of a leveling agent, 3-6 parts of a wax emulsion, 0.5-2 parts of an organic modified silica nanocomposite material, 0.6-1.2 parts of a waterborne thickening agent and 5-10 parts of water. The prepared waterborne woodware matte white finish has prominent scratch resistance, high hardness and good water resistance and chemical resistance.

Description

technical field [0001] The invention relates to the field of coatings for architectural decoration, in particular to a water-based wood matt white finish with high scratch resistance and high performance. technical background [0002] In recent years, the rapid economic development has led to the rapid destruction of the environment. Environmental problems such as smog and photochemical pollution have occurred frequently, affecting people's lives and health. Environmental protection has become an urgent matter. Water-based wood lacquer has received widespread attention because of its environmental protection, health, and non-toxicity to humans. However, compared with traditional oil-based wood lacquers, their properties, such as scratch resistance, hardness and chemical resistance, are insufficient, which makes water-based wood lacquers mostly only used for low-end children's toys at present. There are less applications such as office furniture with high requirements for du...
