Problems solved by technology

Condensation or frost on the inner surface of the glass will seriously affect the perspective of the insulating glass and reduce the heat insulation performance of the insulating glass. At the same time, long-term condensation or frost will cause mildew on the inner surface of the glass and cause white spots
At present, the service life of domestic insulating glass is greatly shortened due to some technical problems. Some products will frequently appear fogging, condensation, frosting, and self-explosion. These phenomena lead to the durability, safety, heat insulation, and sound insulation of insulating glass. discount

Abstract

The invention discloses a high-leakproofness waterproof sealant for hollow glass. The sealant is prepared from, by weight, 15-25 parts of polydimethylsilane, 7-15 parts of polyisobutene, 6-13 parts of 3-hydroxyl butyronitrile, 4-9 parts of vinyl triethoxy silane, 3-6 parts of (gamma-aminopropyl)triethoxy silane, 2-3 parts of di(3-triethoxysilylpropyl)tetrasulfide, 2-4 parts of polydimethylsiloxane, 1-3 parts of trimethyl silicane, 3-6 parts of vinyl trimethoxy silane, 1-3 parts of borosilicate, 3-7 parts of allyl orthosilicate, 5-10 parts of p-isopropoxy methyl benzoate, 3-5 parts of 2-ethyl acryloyl chloride, 5-8 parts of crosslinking agent and 4-6 parts of plasticizer. The prepared high-leakproofness waterproof sealant for the hollow glass is good in leakproofness and has waterproofness. Meanwhile, the invention further discloses a corresponding preparation method.

Description

technical field [0001] The invention relates to the technical field of insulating glass, in particular to a highly airtight waterproof sealant for insulating glass and a preparation method thereof. Background technique [0002] As a high-efficiency energy-saving product, insulating glass has been widely used in buildings. In other industries such as railway transportation, the amount of refrigeration industry is gradually increasing. Insulating glass consists of two or more pieces of glass, separated by a spacer and sealed with a sealant to form a glass processing product with a dry gas space between the glasses. The hollow glass has a dry gas or inert gas in the cavity and cannot communicate with the outside world. The gas is convected, thus playing a good heat insulation effect. However, when the ambient temperature is reduced to such that the temperature of the glass surface is lower than the dew point of the gas in the air layer, the water vapor in the air layer will c...
