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 sound-insulation and heat-insulation hollow-glass spacing bar. The sound-insulation and heat-insulation hollow-glass spacing bar is prepared from, by weight, 14-18 parts of polydimethylsiloxane, 5-10 parts of hexamethyldisiloxane, 4-9 parts of ring methyl siloxane, 4-9 parts of vinyltriethoxysilane, 4-7 parts of sodium acrylate, 3-6 parts of butyl nitrite, 2-7 parts of ethyl chloroformate, 5-11 parts of white carbon black, 4-6 parts of isoamyl chloride, 5-7 parts of 3-hydroxy-2-butanone, 2-3 parts of sodium hydrogen sulfite, 4-8 parts of maleic anhydride, 1-3 parts of benzoyl chloride, 2-3 parts of copper chloride, 1-4 parts of sulfamic acid, 3-5 parts of sodium ethoxide, 5-8 parts of a crosslinking agent and 4-6 parts of a thickening agent. The sound-insulation and heat-insulation hollow-glass spacing bar is good in sound insulation and heat insulation. In addition, the invention further discloses a relevant preparation method.

Description

technical field [0001] The invention relates to the technical field of hollow glass, in particular to a sound-insulating and heat-insulating insulating glass spacer 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 ...
