Abstract

The invention provides thermal insulation hollow glass. The thermal insulation hollow glass comprises an outer glass layer, an inner glass layer and hollow separating bars. The thermal insulation hollow glass is characterized in that the hollow separating bars are disposed in the periphery between the outer glass layer and the inner glass layer, the outer glass layer and the inner glass layer are adhered to the hollow separating bars through butyl adhesive, a sealant is put at the outsides of the hollow separating bars, and between the outer glass layer and the inner glass layer, and the adhered outer glass layer, the inner glass layer and the hollow separating bars form a hollow cavity. The outer surface of the outer glass layer is provided with an anatase type nanometer titanium oxide film, the inner surface, faced to the hollow cavity, of the outer glass layer is provided with a low-radiation film, the outer surface of the inner glass layer is provided with a thermal insulation low-radiation film, and inert gas is filled in the hollow cavity. The thermal insulation hollow glass has a lower thermal coefficient, high in visible light transmittance, high in photo-thermal ratio, lower in infrared heat energy transmittance, better in thermal insulation performance and lighter in structural deadweight.

Description

technical field [0001] The invention belongs to the field of architectural glass, and in particular relates to a heat-insulating insulating glass. Background technique [0002] With the progress of society and the improvement of technology level, people have higher and higher requirements for the comfort, energy saving and functionality of residential and public buildings. The national "Twelfth Five-Year Plan" proposes that the construction industry should make breakthroughs in building energy conservation, green building materials, and focus on the use of advanced building materials. In 2014, the "Technical Specifications for Energy-saving Glass for Buildings" drafted by the China Architectural and Industrial Glass Association clearly stated the technical requirements for heat insulation and heat preservation of architectural glass. According to statistics, the energy consumption of buildings in my country accounts for about 30% of the total energy consumption in the count...
