Abstract

The invention discloses a chlorosulfonated polyethylene compounded hot-melt butyl sealant for hollow glass. The sealant is prepared from, by weight, 10-20 parts of butyl rubber, 30-40 parts of polyisobutene, 3-5 parts of chlorosulfonated polyethylene, 5-10 parts of ethylene-propylene rubber, 0.5-1 part of a silane coupling agent A-151, 5-10 parts of furfuryl alcohol resin, 1-2 parts of ethyl hexyl ester of epoxidized soybean oil, 3-5 parts of dibutyl phthalate, 10-15 parts of heavy calcium carbonate, 5-10 parts of quartz powder and 0.5-1 part of polydimethylsiloxane. The chlorosulfonated polyethylene compounded hot-melt butyl sealant for the hollow glass has advantages of high deformation resistance, strength, adhesiveness, water resistance, corrosion resistance, impact resistance, usability and durability.

Description

technical field [0001] The invention relates to the technical field of sealants, in particular to a hot-melt butyl sealant for chlorosulfonated polyethylene composite insulating glass and a preparation method thereof. Background technique [0002] Insulating glass integrates excellent properties such as heat insulation, sound insulation, and lighting. It is an efficient energy-saving product and is widely used in glass curtain walls, automobiles, transportation, and aircraft. As insulating glass enters the field of new buildings in large quantities, people's quality requirements for insulating glass are also getting higher and higher. Insulating glass with long sealing life can not only bring good economic benefits, but also have stronger market competitiveness. Butyl sealant has extremely low water vapor transmission rate and good sealing effect. It is used as the first insulating glass sealant and plays a key role in the comprehensive quality performance of insulating gla...
