A scratch-resistant high-performance water-based wood semi-dumb white finish and preparation method thereof

Abstract

The invention relates to a scratch-endurable high-performance aqueous semi-dumb white paint for woodwork and a preparation method thereof. Specifically, the invention relates to an aqueous white paint for woodwork and belongs to the field of building decorative paint. The invention provides a scratch-endurable high-performance aqueous semi-dumb white paint for woodwork which is prepared mainly by the following raw materials in parts by weight: 55-70 parts of aqueous pure methacrylate resin dispersion, 0.1-0.2 part of aqueous multi-functional adjuvant, 0.2-0.6 part of aqueous disperser, 0.2-0.4 part of aqueous wetting agent, 16-22 parts of titanium pigment, 3-6 parts of film-forming agent, 0.5-1.5 parts of anti-freezer, 0.2-0.4 part of aqueous anti-foam agent, 0.1-0.2 part of antiseptic and bactericidal agent, 0.4-1.2 parts of aqueous leveling agent, 1-3 parts of wax emulsion, 0.6-1.2 parts of aqueous thickener and 5-10 parts of water. The aqueous semi-dumb white paint for woodwork prepared by the invention is characterized by excellent scratch durability, high rigidity 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 scratch-resistant high-performance water-based semi-dull white finish for woodware and a preparation method thereof. Background technique [0002] In the early 1990s, the developed countries in the world started the "green revolution", driving the paint industry to stride forward in the direction of "green" products. In 2008, the EU completely banned the production of solvent-based coatings. Looking around the country, although the Chinese government has not explicitly prohibited the use of solvent-based coatings, however, from the latest standards implemented by the country for five years - the mandatory standard "Limits of Hazardous Substances in Interior Decoration Materials and Interior Wall Coatings" (GB 18582- 2008); on June 1, 2010, the latest national standard - mandatory standard GB24410-2009 "Limits of Harmful Substances in Waterborne Wood Coating...

Problems solved by technology

However, due to the hydrophilic modification of the film-forming substance of the water-based wood paint, the water and chemical resistance performance is reduced. Usually, the matte wood paint is prepared by adding matte powder (silicon dioxide) to extinction, but the matte powder The addition of water and chemical resistance will further decrease

The film-forming process of water-based wood paint is divided into volatilization of water, accumulation, fusion, and film-forming of latex particles. Defects are prone to occur in the film-forming process, resulting in poor hardness and scratch resistance.

These performance deficiencies have seriously hindered the application and development of waterborne wood
