Composite hollow glass for building and preparation method thereof

Abstract

The invention discloses composite hollow glass for a building and a preparation method of the composite hollow glass. The composite hollow glass comprises a first glass layer, a second glass layer, a third glass layer and a fourth glass layer, wherein the first glass layer, the second glass layer, the third glass layer and the fourth glass layer are sequentially combined. The first glass layer and the second glass layer are bonded through a first glue sheet layer, and the outer side face of the first glass layer and the outer side face of the second glass layer are coated with a first antireflection film and a second antireflection film respectively. The third glass layer and the fourth glass layer are bonded through a second glue sheet layer, and the outer side face of the third glass layer and the outer side face of the fourth glass layer are coated with a third antireflection film and a fourth antireflection film respectively. The edge of the outer side face of the second glass layer and the edge of the outer side face of the third glass layer are bonded in a sealing mode through a spacing bar. The composite hollow glass further comprises a first electric heating assembly which is arranged in the first glue sheet layer, and the electric heating assembly is connected with a power supply for heating the hollow glass. The composite hollow glass has the good mechanical property, the good thermal property and the good optical property, and the requirements of high and medium grade high-rise buildings for permeability and temperature controllability can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a composite hollow glass used in buildings and a preparation method of the composite hollow glass. Background technique [0002] As the pace of urbanization progresses faster and faster, the architectural windows of houses are also becoming larger and larger. Elegant, beautiful and functionally safe glass components are gradually being favored by domestic and foreign designers, which directly leads to the rapid development of various safety glass and special glass in the architectural glass industry. Architectural glass has gradually developed from simply being used as a lighting and decorative material to have multiple functions such as light control, room temperature adjustment, noise reduction, and improvement of the living environment. [0003] Windows are the main components of building envelopes, and the performance of windows will greatly affect the...
