Embodiment 1

[0024] This embodiment provides a radiation cooling glass, comprising: a glass substrate 20 and a transparent radiation cooling film coating 10, the glass substrate 20 is located under the radiation cooling film coating, and the glass substrate 20 is ordinary glass. Wherein, the thickness of the transparent radiation cooling film coating 10 is 1-30um, and the components and mass parts of the transparent radiation cooling film coating 10 are: polymer resin: 20-40 parts, micron powder: 25-40 parts 50 parts, paint additives: 3-10 parts, thinner: 20-30 parts. Wherein, it should be noted that the thickness of the transparent radiation cooling film coating 10 is determined according to the comprehensive requirements of cooling, lighting and aesthetics.

[0025] The polymer resin in the component 10 of the transparent radiation cooling film coating is water-based polyurethane and / or epoxy resin. The micron powder in the components contains at least indium tin oxide (ITO), titanium d...

Embodiment 2

[0031] This embodiment provides a combination of the first glass substrate 201 and the second glass base layer 202 to form a double-layer structure to replace the single-layer glass substrate 20 in the first embodiment. That is, the glass substrate 20 is set as a double-layer structure, the glass substrate 20 is divided into upper and lower layers, the first glass substrate 201 is located below the transparent radiation cooling film coating 10, the second glass substrate 202 is located below the first glass substrate 201, and the second glass substrate 202 is located below the first glass substrate 201. A cavity 30 is formed between the first glass substrate 201 and the second glass substrate 202 . Air and / or Ar are contained in the cavity 30, so that the heat insulation effect can be increased, so that the high-temperature heat outside cannot easily enter the room through the glass substrate 20, while the heat inside the room can radiate into space through the transparent radi...

Abstract

The invention discloses radiation cooling glass and a preparation method thereof. The radiation cooling glass comprises a glass substrate and a transparent radiation cooling film coating, the glass substrate comprises a first glass substrate body and a second glass substrate body, a cavity is reserved between the first glass substrate body and the second glass substrate body, the thickness of thetransparent radiation cooling film coating is 1-30 microns, and the transparent radiation cooling film coating is prepared from the following components in parts by mass: 20-40 parts of polymer resin,25-50 parts of micron powder, 3-10 parts of coating additive and 20-30 parts of diluent. The invention provides the novel transparent radiation cooling film coating. The transparent radiation coolingfilm coating comprises one or more of the main components of indium tin oxide (ITO), titanium dioxide (TiO2), silicon dioxide (SiO2) or zinc oxide (ZnO). The coating has the advantages that sufficient sunlight visible light transmittance can be ensured, meanwhile, heat absorbed by the coating from the periphery can be emitted to the outer space with strong infrared radiation capability, and therefore a remarkable cooling effect can be achieved.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to a radiation-cooled glass and a preparation method thereof. Background technique [0002] With the intensification of the greenhouse effect, the energy consumption of refrigeration continues to rise, but the glass used in buildings currently has no real cooling function. The glass used to reduce the energy consumption of air conditioners in the existing market is mainly heat insulation and solar control glass. They only reduce the transfer of heat from the outside to the building, but do not have the effect of transferring heat from the room to the outside. [0003] Solar control glass is generally coated with one or more layers of thin films composed of metals such as chromium, titanium or stainless steel or their compounds on the surface of the glass, so that the product is rich in color, and can effectively shield the entrance of the sun under the condition of ensuring soft ...
