Abstract

The invention discloses radiated-cooled glass and a preparation method thereof. The radiated-cooled glass comprises a glass substrate, at least one oxide layer and a coating layer which are disposed in sequence, wherein the oxide layer has a certain visible light transmittance and a high near-infrared reflectance, and the coating layer comprises a light-transmitting polymer material and inorganicparticles dispersed in the polymer material; the inorganic particles have a high emissivity in a wavelength band of 7 to 14 [mu]m. The radiant-cooled glass disclosed by the invention has good opticalproperties, and the transmittance of visible light in the sunlight can be adjusted between 40 percent and 90 percent, and the reflectance of the visible light is very low; compared with traditional coated glass, the radiated-cooled glass has greatly improved optical performance; the radiant-cooled glass disclosed by the invention also has excellent thermal properties, can realize passive cooling of buildings when applied to the buildings, and meets the requirements of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of radiation cooling, in particular to a radiation cooling glass and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, the proportion of building energy consumption to the total energy consumption of the society is gradually increasing. Taking my country's air-conditioning energy consumption as an example, the energy consumption of air-conditioning residential buildings is about 6 to 7 times that of ordinary residential buildings. Under the current situation of energy shortage, attention must be paid to building energy-saving technologies. As a means of building air-conditioning without energy consumption, radiant cooling has developed vigorously and shown obvious practical significance. [0003] The analysis of the transmission characteristics of the atmospheric spectrum shows that the atmosphere has diff...
