Abstract

The invention discloses photochromic architectural glass and a preparation method thereof, and relates to the field of building materials. The photochromic architectural glass comprises the followingraw materials in parts by weight: 30-50 parts of a styrene-methyl methacrylate copolymer, 10-20 parts of organic glass, 0.1-0.3 part of an initiator, 50-60 parts of titanium dioxide, 6-8 parts of tungsten oxide, 6-8 parts of sodium bromide, 0.2-0.4 part of copper oxide, 0.3-0.5 part of an antifoaming agent, and 0.4-0.6 part of a catalyst. The photochromic architectural glass disclosed by the invention has significantly-improved quality, mechanical impact strength and transparency compared with glass prepared by a conventional process, and silver bromide in the raw material component can be decomposed in the case of strong light, so that the light transmittance of the architectural glass disclosed by the invention is obviously reduced, and the architectural glass has a light-insulating effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a photochromic building glass and a preparation method thereof. Background technique [0002] Photochromic glass is a new type of energy-saving glass. When the light is enhanced, the glass gradually becomes darker, which reduces the transmittance of light and heat; when the light is weakened, the glass becomes bright again, which improves the transmittance of light and heat. Rate. This kind of smart glass, which can automatically change the light transmittance and shading coefficient according to the environmental changes in the morning and evening and the four seasons, has the advantages that star energy-saving glasses such as low-emissivity Low-E do not have, and has attracted special attention. [0003] The patent application with the publication number CN201710444104.5 discloses a kind of architectural glass and its production process. The architectural glass is p...
