Problems solved by technology

However, ordinary insulating glass is not selective to the solar spectrum. In order to ensure high visible light transmittance, the heat in the near-infrared region must pass through the insulating glass through direct radiation, so the heat insulation effect is limited.
In order to enhance the heat insulation effect, one or both sides of the insulating glass are coated to form a coated insulating glass. However, due to the darker color of the coating, the visible light transmittance decreases, which increases the energy consumption of indoor lighting instead. The original intention of energy saving
Therefore, the large-scale application of insulating glass is limited

Abstract

The invention relates to the technical field of research and development of glass performance and discloses a nano heat-insulation coating layer applied to hollow glass. A nano composite material withthe mass percent of 0.75 to 0.80 percent is added into acrylic emulsion coating; the nano composite material has good spectral selectivity, high light transmittance in visible light and high rejection rate in an infrared light region; the stable and uniform nano heat-insulation coating is prepared; after the hollow glass is coated with the coating, the coating is cured under a low-temperature baking condition to obtain the transparent, uniform and flat heat-insulation coating layer; the heat-insulation coating layer has good mechanical properties, relatively strong rigidity and excellent adhesive force; the nano heat-insulation coating layer can be applied to windshield glass of automobiles, trains and airplanes, and building glass, has very good heat-insulation and cooling effects and has no reflection light pollution.

Description

technical field [0001] The invention belongs to the technical field of glass research and development, and in particular relates to a nano heat-insulating coating applied to insulating glass. Background technique [0002] Insulating glass was invented by Americans in 1865. It is a new type of building material with good heat insulation, sound insulation, aesthetics and applicability, and can reduce the self-weight of buildings. It uses two (or three) pieces of glass and uses high strength and high strength. The airtight composite adhesive is used to bond the glass sheet to the aluminum alloy frame containing the desiccant to form a high-performance sound-insulating and heat-insulating glass. The performance of insulating glass is superior to that of ordinary double-layer glass, so it has been recognized by all countries in the world. Insulating glass is to separate two or more pieces of glass evenly with effective support and bond and seal the periphery, so that a dry gas is...
