Thermal insulation laminated safety glass and manufacturing method thereof

Abstract

The invention provides a thermal-insulating heat-preserving laminated safety glass and a manufacturing method thereof. The structure of the thermal-insulating heat-preserving laminated safety glass comprises, from top to bottom, a first glass layer, a transparent thermal-insulating coating the inner surface of the first glass layer, a polymer film and a second glass layer; or the thermal-insulating heat-preserving laminated safety glass is further provided with a gas spacing layer and a third glass layer. The manufacturing method comprises the following steps: (1) preparing the transparent thermal-insulating coating; and (2) preparing the thermal-insulating heat-preserving laminated safety glass; or preparing a thermal-insulating heat-preserving laminated safe hollow glass from the thermal-insulating heat-preserving laminated safety glass. The thermal-insulating heat-preserving laminated safety glass or thermal-insulating heat-preserving laminated safe hollow glass has good impact resistance, low shading coefficient, low thermal coefficient, low ultraviolet transmittance, high visible transmittance and low near-infrared transmittance and is capable of preventing radiant heat of the sun entering a room in summer so as to realize thermal insulation and capable of reducing indoor heat loss in winter so as to realize heat preservation.

Description

technical field [0001] The invention relates to a building energy-saving glass and a manufacturing method thereof, in particular to a thermal insulation laminated safety glass and a manufacturing method thereof. Background technique [0002] In recent years, with the continuous development of human social science and economy, more glass representing architectural aesthetics has entered thousands of households. The use of glass in buildings is for the natural lighting of buildings and to increase the beauty of buildings. While the natural lighting of the building utilizes visible light, ultraviolet and infrared rays also enter the interior. The short-wavelength ultraviolet rays in sunlight not only cause damage to furniture, but also cause skin damage to the human body, causing cancer and other diseases; infrared rays in sunlight enter the room and cause indoor objects or spaces to heat up. The heating is beneficial, but the excessive infrared rays entering the room in summe...

Problems solved by technology

Because the heat insulation mechanism is the heat reflection of the metal film or metal oxide layer used, the metal film or metal oxide layer will cause light pollution to the surrounding environment; the metal film or metal oxide layer is vacuum plasma It is formed by the spraying method and requires expensive equipment to produce; in order to prevent the metal film layer or metal oxide layer from deteriorating in contact with the air, the metal layer and metal oxide layer near the edge of the glass must be polished off before the laminated glass is prepared. , and then use polymer film to seal the edge, the process is complicated and the equipment investment is large; at the same time, the patented technology does not involve the thermal insulation of architectural glass
