Description

technical field

[0001] The invention relates to a double vulcanization system building sealant and a preparation method thereof, belonging to the technical field of building sealants. Background technique

[0002] Dealcoholized silicone building sealant is divided into one-component dealcoholized building sealant and two-component dealcoholized building sealant, with low odor, no corrosion, environmental protection and good performance on glass, metal and most substrates adhesiveness. With the rapid development of electronic appliances, automobile transportation, civil construction and other industries and the higher and higher requirements for environmental protection, the demand for dealcoholized silicone rubber is increasing, and it has become an important research project for sealant enterprises.

[0003] At present, the dealcoholized sealants in the domestic market still have some shortcomings, such as the problem of deep curing, whether it is two-component or single-c...
