Problems solved by technology

Therefore, the inner seal of the insulating glass must use a sealant with a very low water vapor transmission rate. If the water vapor transmission rate is high, water vapor will penetrate into the insulating glass through the sealant, and the insulating glass will easily appear. Dew point phenomenon, making insulating glass invalid
In addition, the hollow glass is exposed to direct sunlight for a long time, and the temperature in summer may be as high as 60°C. The sealant will experience cold flow at high temperatures, which will affect the use effect.
[0004] In response to the above problems, our company has developed an inner sealant for insulating glass processing. Its water vapor transmission rate and cold flow rate are extremely low, which can effectively play the role of inner seal and prevent the performance of the inner sealant from being unsatisfactory. Requirements lead to the occurrence of insulating glass failure problems

Abstract

The invention discloses inner-channel sealant for hollow glass processing and a preparation method thereof, and relates to the technical field of hollow glass processing. The inner-channel sealant is prepared from the following raw materials in parts by weight: 10-15 parts of bisphenol A epoxy resin-hydrolytic polymaleic anhydride, 10-15 parts of polytetrafluoroethylene superfine powder, 5-10 parts of coal ash, 5-10 parts of polyoxyethylene, 1-5 parts of polyethylene glycol monomethyl ether-polyglutamic acid, 1-5 parts of trimethylolpropanetriglycidylether, 0.5-2 parts of bismaleimide resin and 0.5-2 parts of sepiolite fiber powder. The inner-channel sealant is used as first seal of hollow glass, can exert excellent effects of isolating water and air, and is extremely low in steam transmission rate and cold fraction, so that the sealing effect is guaranteed, and the hollow glass is prevented from being invalid.

Description

Technical field: [0001] The invention relates to the technical field of hollow glass processing, in particular to an inner sealant for hollow glass processing and a preparation method thereof. Background technique: [0002] Insulating glass is a glass product in which two or more pieces of glass are evenly spaced for effective support and bonded and sealed around the periphery to form a dry gas space between the glass layers. The various properties of insulating glass are superior to ordinary double-layer glass, which can effectively play the function of sound insulation and heat insulation. The thermal conductivity of glass is 27 times that of air. As long as the insulating glass is sealed, it can exert its best sound insulation effect. Therefore, in the production of insulating glass, the selection of appropriate edge sealing materials and good peripheral frame materials is the key to improving the sound insulation and heat insulation performance of insulating glass.
