Problems solved by technology

However, the organosilicon sealant widely used on insulating glass in the prior art cannot reach a satisfactory level due to the effect of preventing water vapor from passing through, so that the service life of the insulating glass system cannot be guaranteed to meet the expected requirements. It largely restricts the application on insulating glass

Abstract

The invention discloses a sealant for hollow glass. The sealant is prepared from the following components in parts by weight: 100 parts of alpha, omega-dihydroxyl polydimethylsiloxane, 10-12 parts of methyl methacrylate, 14-16 parts of polydimethylsiloxane, 24-26 parts of basic zinc carbonate, 16-18 parts of zinc borate, 9-11 parts of quartz powder, 10-12 parts of silica powder, 8-10 parts of kaolin, 16-18 parts of triethoxyvinylsilicon, 8-10 parts of gamma-methacryloxypropyltriethoxysilane and 0.3-0.5 part of dibutyltin diacetate; the transmittance of the water vapor of the sealant is 0.2-0.4; and the tensile strength is 0.6-0.8.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a sealant for insulating glass. Background technique [0002] The insulating glass is composed of two or three pieces of glass, which are bonded and sealed around the periphery with an adhesive. A dry inert gas space is formed between the glass layers to make a high-efficiency sound insulation and heat insulation insulating glass system. The insulating glass system has good heat insulation and sound insulation performance, beautiful and practical, and can reduce the weight of the building. It is a new type of building material. [0003] At present, the main problem of insulating glass in our country is the short service life, which is mainly manifested in the fact that condensation or frost is prone to occur after a period of use such as one year or several years. Although the glass is not broken, the role it should play as insulating glass has already Nothing left. The servic...
