[0053] Example
[0054] The silane-terminated aliphatic isocyanate prepolymer is prepared as follows:
[0055] 350 grams of polyoxypropylene triol (average molecular weight 350) was added to the reactor with mechanical stirring, nitrogen protection and heating device. Heat to 50°C under the protection of nitrogen, then add 1512g of 1,6-hexamethylene diisocyanate biuret, stir evenly, add 1g of dibutyltin dilaurate, keep at 70°C and stir for 4h, then add mercaptopropyltrimethoxy 1176g of base silane, the reaction was continued at 50°C for 4 hours to obtain a silane-terminated aliphatic isocyanate prepolymer.
[0056] The adhesion promoter is prepared as follows:
[0057] 269 grams of N-(2-aminoethyl)-3-aminopropyltriethoxysilane was added to the reactor equipped with mechanical stirring, nitrogen protection and heating device. Heat to 80°C under the protection of nitrogen, then add 236 grams of (3-glycidoxypropyl) trimethoxysilane, stir evenly, and continue to keep the temperature a...
