Problems solved by technology

In patent applications 200410075486.1 and 200410065860.X, nano-titanium dioxide (actually anatase nano-titanium dioxide, also known as photocatalyst) is used as the main antibacterial component. The disadvantage is that photocatalyst reaction needs to occur under the irradiation of ultraviolet light (including the ultraviolet band in natural light) , and will cause degradation of organic components including the paint itself

Abstract

The invention discloses a preparing method of single component nanometer antibiotic water-based woodware paint, which is characterized by the following: the three diverse water-based polyurethane resin emulsion, water-based acrylic acid modified polyurethane resin emulsion and nanometer water-based acrylic resin emulsion are mixed with diverse ratio as film forming matter; it drops the cost of this product and possesses merits of low VOC value, blocking resistance, fish tail tolerant, pollution tolerant, yellowed tolerant and good blocking; the organic swelled ground prefabricated sol is the carrier of compositing type inorganic antibacterial agent, it incorporates multiple inorganic nanometer composition. This invention is easy to process, which can resolve craft problems of sedimentation, discoloration and birdnesting.

Description

【Technical field】 [0001] The invention relates to a paint, in particular to a single-component nanometer antibacterial water-based wood paint and a preparation method thereof. 【Background technique】 [0002] At present, most of the traditional wood lacquers are solvent-based wood lacquers, mainly solvent-based polyurethane and nitro-lacquer. Due to the relatively high total volatile organic compound (VOC), this kind of wood lacquer has relatively large environmental pollution and affects people's health. Especially with the widespread use of computers, people's lifestyles have gradually changed from outdoors to indoors, which is more likely to cause serious "indoor environmental pollution". [0003] Internationally, the use of solvent-based wood lacquers has been strictly restricted. In Europe, the production and sales of solvent-based paints were completely banned in 2004. my country also plans to completely ban solvent-based wood lacquers by 2008. And water-based wood ...
