Abstract

The invention belongs to the technical field of functional building paint and relates to photochromic glass paint and a preparation method thereof. The photochromic glass paint is prepared from the following raw materials in weigh ratio: 20 to 50 parts of prepolymer, 5 to 20 parts of active monomer, 0.1 to 1 part of initiator, 5 to 20 parts of color changing powder, 0.1 to 1 part of wetting agent,0.1 to 1 part of dispersant, 0.5 to 3 parts of adhesion promoter, 0.5 to 2 parts of enhancer and 0.5 to 3 parts of nano material. The surface of general glass is simply coated with one layer of the photochromic glass paint disclosed by the invention, so that the general glass can achieve a photochromic effect; thus, the surface of the general glass can be coated with the paint in a large scale infactories to manufacture photochromic glass, and construction can be performed in existing building sites to manufacture the photochromic glass.

Description

technical field [0001] The invention belongs to the technical field of functional architectural coatings, and relates to a photochromic glass coating and a preparation method thereof. Background technique [0002] Photochromic glass is a kind of glass that can change its color depth according to the intensity of light, and change the transmittance of visible light and infrared light, thereby changing the shading coefficient of the glass and achieving the purpose of energy saving. Therefore, photochromic glass is a kind of intelligent energy-saving glass. [0003] At present, there are two preparation methods for photochromic glass. One method is to add photochromic material into the glass body, and the other is to make photochromic material into a film and then compound it with glass. But these two kinds of preparation methods all have complicated process, can only process photochromic glass in factory, can't construct photochromic glass in existing construction site. Con...
