Embodiment 1

[0020] A method for preparing energy-saving glass with dual effects of UV protection and photochromism, comprising the following steps:

[0021] 1) molybdenum trioxide (MoO 3 ), titanium dioxide (TiO 2 ), zinc oxide (ZnO), cerium oxide (CeO 2 ), cobalt oxide (CoO) and silicon dioxide (SiO 2 ) and other nanoparticles in proportion to be prepared into an ethanol solution with a concentration of 1mol / L, then add a certain concentration of dispersant, put into a disperser and disperse for 10 minutes, fully mix, then add to a ball mill and carry out ball milling for 3 hours to obtain Nano powder with good dispersion, smaller size and more uniform.

[0022] 2) Using glass as the substrate, ultrasonically clean it with detergent, acetone, alcohol and ultrapure water for 10 minutes each, and rinse with ultrapure water to form a uniform water film on the glass surface. After the glass substrate is cleaned, dry the moisture on the surface with a nitrogen gun, and put it into a clean...

Embodiment 2

[0027] A method for preparing energy-saving glass with dual effects of UV protection and photochromism, comprising the following steps:

[0028] 1) molybdenum trioxide (MoO 3 ), titanium dioxide (TiO 2 ), zinc oxide (ZnO), cerium oxide (CeO 2 ), cobalt oxide (CoO) and silicon dioxide (SiO 2 ) Nanoparticles are formulated into ethanol solution with a concentration of 2mol / L in proportion, then add a certain concentration of dispersant, put into a disperser and disperse for 15 minutes, fully mix, then add to a ball mill and carry out ball milling for 4 hours to obtain a dispersed Good properties, smaller size, more uniform nano-powder.

[0029] 2) Use glass as the substrate, ultrasonically clean it with detergent, acetone, alcohol and ultrapure water for 15 minutes, and rinse with ultrapure water to form a uniform water film on the glass surface. After the glass substrate is cleaned, use a nitrogen air gun Dry the moisture on the surface and put it into a clean petri dish fo...

Abstract

The invention belongs to the technical field of functional building materials, relates to ultraviolet-proof energy-saving glass and mainly provides nano powder with dual effects of ultraviolet proofing and photochromism and a preparation method thereof. The photochromic composite nanoparticle with the ultraviolet proofing effect is mainly formed by molybdenum trioxide (MoO3), titanium dioxide (TiO2), zinc oxide (ZnO), cerium dioxide (CeO2), cobalt oxide (CoO) and silicon dioxide (SiO2). By adopting glass as a matrix, a composite film is formed by coating the inorganic composite nano powder onthe glass through a wet coating method to prepare the ultraviolet-proof energy-saving glass. The photochromic composite nano powder provided by the invention has excellent dispersibility, oxidation resistance and light transmittance; the preparation method is simple in process, stable and controllable in process, high in color change response speed, low in equipment and raw material costs, easy tooperate, free of toxicity or pollution and convenient for industrial mass production.

Description

technical field [0001] The invention belongs to the research field of functional building materials, and in particular relates to an inorganic nano-powder with dual functions of UV protection and photochromism, which is applied to energy-saving glass, and a preparation method thereof. Background technique: [0002] Glass can be seen everywhere in our daily life, such as ordinary glass drinking glasses used in homes, large glass windows in buildings, automotive glass and eyeglass lenses, etc. According to statistics, architectural glass accounts for more than 85% of the glass market, and energy consumption lost through glass doors and windows accounts for more than 40% of building energy consumption. Therefore, it is an urgent task to take energy-saving measures for glass. Moreover, under the vigorous promotion of the national energy-saving and emission-reduction policy, my country has further intensified the application of energy-saving materials for new buildings and the en...
