Transparent heat-insulating glass glaze material and preparation method thereof

Abstract

The invention discloses a transparent heat-insulating glass glaze material and a preparation method thereof. The method specifically comprises the following steps: uniformly mixing low-melting-point glass powder, a thermal radiation blocking agent and a thermal conduction blocking agent to obtain a heat-insulating glass glaze material, wherein the ratio of the parts by mass of the low-melting-point glass powder to the thermal radiation blocking agent to the thermal conduction blocking agent is (70-90):(5-15):(5-15), the thermal radiation blocking agent is ITO (indium tin oxide) nano powder, ATO (antimony-doped tin oxide) nano powder, FTO (fluorine-doped zinc oxide) nano powder or ZTO (zinc-doped tin oxide) nano powder, the vitrification transformation temperature of the low-melting-point glass powder is less than or equal to 600 DEG C, and the thermal conduction blocking agent is nano silicon dioxide aerogel. When the above heat-insulating glass glaze material is used for preparing a transparent heat-insulating coating, because organic glass is adopted as a filming medium, the properties of stability, ultraviolet aging resistance, wear resistance and the like of a material can be significantly improved. Therefore, the heat-insulating glass glaze material has a broad application prospect in the field of architectural glass.

Description

technical field [0001] The invention belongs to the technical field of preparation of building energy-saving materials, and in particular relates to a transparent heat-insulating glass glaze and a preparation method thereof. Background technique [0002] As the society pays more and more attention to green, environmental protection and energy saving, people put forward higher and higher requirements for the transparency and heat insulation performance of glass. Although ordinary glass has good transparency, its thermal insulation effect is not good, which causes a lot of energy loss and energy consumption. There are three ways of heat transfer in glass: radiation, conduction and convection, of which radiation heat transfer accounts for 60% and conduction heat transfer accounts for 38%. Therefore, in order to improve the thermal insulation performance of glass, it is necessary to start from both radiation heat transfer and conduction heat transfer. Low-E glass and insulatin...

Problems solved by technology

However, the film-forming aids used in this method are generally organic substances such as organic resins, polycarbonates, etc., which limit their service life. Performance is still lacking

[0004] In addition, the heat insulation film formed by transparent conductive oxide only has a blocking effect on radiation heat transfer, and cannot reduce the conduction heat transfer of glass materials, and the heat preservation and heat insulation effect is limited.
