Abstract

The invention discloses hollow glass based on a single-component solventless hot melt adhesive, the hollow glass comprises inner layer glass, outer layer glass, spacing bars, membrane material interlayers and edge sealing metal membranes, the spacing bars are packaged between the peripheries of the inner layer glass and the outer layer glass through the hot melt adhesive, and the peripheries of the membrane material interlayers are respectively adhered to the inner sides of the corresponding spacing bars through the hot melt adhesive. The membrane material interlayers are used for separating a space between the inner-layer glass and the outer-layer glass, and the edge sealing metal membrane is adhered to the spacing bar through a hot melt adhesive and wraps the outer side surfaces of the inner-layer glass and the outer-layer glass on the two sides; the hot melt adhesive is prepared from the following raw materials in parts by weight: 30 to 50 parts of isocyanate, 60 to 90 parts of polyester polyol, 10 to 30 parts of polyether polyol, 0.1 to 5 parts of a chain extender, 0.1 to 3 parts of a hydrolysis-resistant agent, 0.1 to 2 parts of an adhesion promoter, 0.1 to 2 parts of a latent curing agent, 0.1 to 0.5 part of a catalyst and 0.1 to 0.3 part of an antioxidant. Through cooperation of the optimized structure and the hot melt adhesive, the heat insulation, sound insulation and barrier properties of the hollow glass are improved, and the hollow glass is light in weight.

Description

technical field [0001] The invention relates to a hollow glass based on a single-component solvent-free hot-melt adhesive and a processing method thereof, belonging to the technical field of hot-melt adhesives. Background technique [0002] Insulating glass was invented by the Americans in 1865, which is a new type of building material with good heat insulation, sound insulation, aesthetics and applicability, and can reduce the weight of buildings. It is a high-performance sound-insulating and heat-insulating glass made of two (or three) pieces of glass, using a high-strength and high-air-tight composite adhesive to bond the glass pieces to the aluminum alloy frame containing the desiccant. 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 ...
