AI Technical Summary

Problems solved by technology

The four-corner plug-in aluminum spacer is likely to become a weak link for external moisture intrusion at the four-corner joints, which shortens the service life of the insulating glass, generally about 10 to 15 years, and replacement at that time will bring greater losses to the user.
However, its use does not involve solving the problems of insulating glass spacers. Therefore, it is urgent to provide an insulating glass spacer with low thermal conductivity, good sealing performance, elimination of insulating glass stress, reduction of glass deflection and elimination of condensation around the insulating glass. strip

Abstract

This invention relates to a micro-hole rubber hollow glass spacing strip used in hollow glasses composed of rubber, curing agent and aids characterizing that said rubber is composed of EPT rubber and molecular sieve activation powder with the following weight percentage: EPT rubber 100 portions, activation powder 80-200 portions.

Description

technical field [0001] The invention relates to a microporous rubber hollow glass spacer used in hollow glass. Background technique [0002] As the country attaches great importance to building energy saving, the production and improvement of insulating glass, which must be used in buildings and directly affects energy saving, is imminent. The main means of improving the energy-saving performance of insulating glass are LOW-E (plating low-radiation material silver and metal oxide film on the glass surface to reduce radiation) and inert gas. The traditional (and the most commonly used) insulating glass is made of metal aluminum as a spacer and filled with molecular sieves and then sealed with a double-channel sealant. Since the thermal conductivity (2.0) of the aluminum spacer is much higher than the thermal conductivity (0.03) of the air layer, a large amount of heat passes through the insulating glass through the edge sealing area, which has a great influence on the therma...
