Novel composition for intelligent dimming glass

Abstract

The invention relates to an energy-saving material, and particularly relates to a novel composition for intelligent dimming glass. The invention provides a novel composition for intelligent dimming glass in view of the technical defects that the intelligent dimming glass in the prior art is not ideal in shading effects, slow in response speed and the like. The novel composition comprises the following components: a thermosensitive polymer, a viscosity modifier, infrared absorption functional particles, a macromolecular solvent and an additive. The novel composition for the intelligent dimming glass provided by the invention has an automatic dimming function, the effects of warming in winter and cooling in summer are achieved, and the novel composition has good shading effects and simple preparation process, is a novel and efficient material for energy-saving and cost-reducing glass products, and has broad application prospect.

Description

technical field [0001] The invention relates to an energy-saving material, in particular to a composition for a novel smart dimming glass. Background technique [0002] In the context of increasingly severe energy supply, energy conservation and consumption reduction has become a strategic issue for the sustainable development of mankind. Building energy consumption accounts for more than 30% of the total energy consumption of the whole society, of which heating and air conditioning account for more than 20%. Among the four building envelope components, the heat lost through doors and windows accounts for more than 50% of the heating and air conditioning energy consumption of the entire building. Western developed countries have carried out research on energy-saving windows since the 1960s, such as heat-reflecting glass and Low-E glass. In recent years, with the continuous advancement of technology, a number of new smart glasses have come out one after another, including p...

The smart dimming glass reported above only uses temperature-sensitive polymers as intelligent response materials, and only responds to changes in ambient temperature. When the ambient temperature is lower than the response temperature of the temperature-sensitive material, but the sun is hot In the case of strong sensitivity, the sunshade effect cannot be produced; when the ambient temperature is higher than the response temperature of the temperature-sensitive material, and the difference between the ambient temperature and the response temperature of the temperature-sensitive material is small, the sunshade effect is not ideal, and the response speed is slow, which cannot effectively achieve intelligence.
