Description
Technical Field
The invention relates to 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
The hollow glass is a novel building material which is invented by Americans in 1865, has good heat insulation and sound insulation, is attractive and applicable, and can reduce the self weight of buildings. The high-efficiency sound-insulating and heat-insulating glass is prepared by bonding two (or three) pieces of glass with an aluminum alloy frame containing a drying agent by using a high-strength high-airtightness composite bonding agent. The hollow glass has various properties superior to those of common double-layer glass, so that the hollow glass is accepted by all countries in the world, and two or more pieces of glass are effectively supported and uniformly separated and are bonded and sealed at the periphery, so that a dry gas space is formed between glass layers. The main materials are glass, warm edge spacing strips, corner bolts, butyl rubber, polysulfide glue and drying agents.
Hollow glass is widely used as a building energy-saving material because of its excellent heat-insulating and sound-insulating properties. Meanwhile, the quality requirement on the hollow glass is higher and higher. It is known that the greatest quality problem of hollow glass is dew formation of the air layer during use, and the reason for dew formation of the air layer is that the dew point of the air layer rises during use. Therefore, the control of the dew point of the hollow glass is the key to the control of the quality of the hollow glass.
The dew point of the hollow glass rises due to the fact that external moisture enters an air layer and is not absorbed by a drying agent, and the dew point can rise for three reasons: (1) air bubbles are stored in the sealant, so that air moisture enters; (2) the water vapor diffuses into the air layer through the polymer; (3) the effective adsorption capacity of the desiccant is low.
Therefore, how to manufacture the hollow glass with excellent sealing performance and high performance of heat insulation, sound insulation and the like becomes a problem to be broken through by researchers in the field.
