Background
The hollow glass is generally accepted as an energy-saving and environment-friendly product due to the characteristics of heat insulation, heat preservation, sound insulation, condensation prevention and the like. The sealing and structural stability of the insulating glass system is dependent on the sealant used. At present, the cementing process in the production of hollow glass mostly adopts two sealing technologies. Wherein, the first seal is an inner seal and adopts butyl rubber with lower water-gas permeability; the two side surfaces of the spacing frame of the hollow glass are coated with the butyl rubber by a hot-melt gluing machine, and the butyl rubber can block moisture and dry a gas cavity and can play a role in sealing and presetting the glass. The second sealing is an outer sealing which usually adopts three types of silicone adhesive, polysulfide adhesive and polyurethane adhesive, at present, the domestic application is mostly the silicone adhesive and the polysulfide adhesive, and the outer sealing not only can bond the glass and the spacing frame into a whole, but also can play auxiliary roles of elastic recovery, edge stress buffering and the like; the outer channel sealing also plays an auxiliary role in sealing the hollow glass, and the main role of the outer channel sealing is to maintain the structural integrity of the hollow glass under the conditions of high and low external temperature change, high humidity and ultraviolet irradiation. Therefore, at present, the silicone structural sealant is selected as the second sealant of the hollow glass, and the structural action of the silicone structural sealant is mainly utilized, so that the second sealant is required to have aging resistance, compatibility and cohesiveness. Chinese patent publication No. CN1810907A discloses a low moisture vapor transmission rate silicone sealant for hollow glass and a method for manufacturing the same, which can ensure low moisture vapor transmission, but does not relate to aging resistance and adhesion.
