Composite light body insulating glass with two pieces of glass and three cavities and manufacturing method thereof

Abstract

The invention relates to composite light body insulating glass with two pieces of glass and three cavities and a manufacturing method thereof. The insulating glass comprises two pieces of glass, warmedge spacing bars and a structural sealant, and also comprises an integrated molding polycarbonate spacing layer with a hollow cavity which is filled with inert gas. The polycarbonate spacing layer isplaced between the two pieces of glass. The warm edge spacing bars are arranged between the two sides of the polycarbonate spacing layer and the glass on the corresponding sides along a circumferential direction, so that air interlayers are respectively formed between the two sides of the polycarbonate spacing layer and the glass. The air interlayers are filled with molecular sieve desiccant. Thewarm edge spacing bars and the two pieces of glass outside the polycarbonate spacing layer are sealed by the structural sealant. The composite light body insulating glass with the two pieces of glassand the three cavities of the invention has the performance of sound insulation, heat insulation, ultraviolet insulation, anti-collision, and light self-weight. The composite light body insulating glass with the two pieces of glass and the three cavities is novel type of energy-saving and safe glass.

Description

technical field [0001] The invention relates to the technical field of door and window glass manufacturing, in particular to a two-glass three-cavity composite lightweight hollow glass and a manufacturing method thereof. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection, energy-saving glass products with thermal insulation functions are gradually welcomed by the market. The demand for energy-saving glass is growing rapidly, and the market has great potential for development. The area of ​​housing built in my country is about 2 billion square meters every year, and only about 10% of the buildings can meet the energy-saving standards stipulated by the state. Most of the buildings are high-energy-consuming buildings. my country is a country with a large energy consumption, and about 30% of energy consumption comes from buildings. The energy consumption per unit area of ​​buildings in my country is more than three tim...

AI Technical Summary

Problems solved by technology

For example, ordinary hollow and vacuum glass have a small barrier rate to radiation, and the heat insulation effect is poor in summer; vacuum glass is prone to self-explosion when the temperature difference between indoor and outdoor is large, and the current technological level cannot reach the mass production scale; coated glass is easy to It is oxidized and loses the effect of heat insulation and energy saving, etc.

[0005] Some regions in my country have adopted three-glass two-chamber glass windows. Although the heat transfer coefficient has been further reduced, the barrier performance to radiation is still poor, and the weight of the window is relatively heavy, which has higher requirements for the load-bearing of the window frame and the building. , which also increases the difficulty of construction
