Problems solved by technology

Ke Bo, Huang Zhijie, etc., The Application of Nano-Silicon Dioxide in Coatings, Coatings Industry, 1998, (12): P29, mentioned that adding nano-silicon dioxide to coatings can improve the thixotropy and anti-aging properties of coatings, and pointed out Nano-silica can absorb more than 70% of ultraviolet rays, so it can improve the anti-aging performance of coatings, but this paper does not give convincing experimental data; meanwhile, Zuo Meixiang, Huang Zhijie, etc., nano-SiO x Dispersion in coatings, New Chemical Materials, Volume 28, (11), P11, also mentioned that nano-silica can improve the anti-aging performance of coatings, but the article pointed out that nano-silica can reflect more than 70% of the UV rays, thus improving the aging resistance of coatings

Abstract

An inorganic composite nanomaterial modified antiageing paint for building is prepared through mixing the composite nano material containing TiO2 particles coated by Si or Al with SiO2 and cerium oxide, adding solvent, assistant filler and acrylic resin, stirring, dispersing and grinding. Its advantages are high antiageing nature improved by 50-120 % and high scrab resistance, water resistance and dirt resistance.

Description

1. Technical field [0001] The invention relates to an anti-aging architectural paint modified by inorganic nanocomposite materials and a preparation method thereof, belonging to the field of architectural paint preparation. 2. Background technology [0002] US Patent No. 5759746, Fabrication process using a multi-layer antireflective layer, reports the preparation of an assembly antireflective coating technology with nano-silicon dioxide added on semiconductor integrated circuit boards. This technology is mainly to prevent some semiconductor integrated circuit boards from For example, a kind of protective layer provided by the influence of ultraviolet rays on the etching performance of circuit boards in semiconductor memory and lithography technology; The technology of ultra-smooth coating, a small amount of nano-oxide material is added to the coating to improve the strength and smoothness of the coating. Ke Bo, Huang Zhijie, etc., The Application of Nano-Silicon Dioxide in...
