Embodiment 1
[0032] Weigh 25 g of bromobutyl rubber and 1 g of butyl imidazole respectively. At a high temperature of 150°C, the mixture of components was cured in an internal mixer to obtain butyl imidazole-modified brominated butyl rubber INR. Weigh 1.6g of modified bromobutyl rubber INR and 30g of petroleum ether, and mix them for later use. After the mixture has stood at room temperature for more than 4 days, heat it in a water bath for 1 hour, and dissolve the INR with petroleum ether at 65°C to form a uniform mixture. solution to obtain a solution-like modified bromobutyl rubber INR. Weigh 0.16g of CB and 24g of deionized water, and stir with a high-speed mixer to form a uniform suspension. At a temperature of 65°C, slowly pour the CB suspension into the INR solution while stirring, and keep stirring for 20 min to obtain a CB@INR mixture. After removing the excess moisture layered out of the mixture material obtained in the previous step, pour it into a petri dish, place it in an o...
Embodiment 2
[0034] Weigh 26 g of bromobutyl rubber and 1 g of butyl imidazole respectively. At a high temperature of 150°C, the mixture of components was cured in an internal mixer to obtain butyl imidazole-modified brominated butyl rubber INR. Weigh 1.5g of modified bromobutyl rubber INR and 30g of petroleum ether, and mix them for later use. After the mixture is allowed to stand at room temperature for more than 4 days, heat it in a water bath for 1.5 hours, and dissolve the INR with petroleum ether at 65°C to form a uniform mixture. solution to obtain a solution-like modified bromobutyl rubber INR. Weigh 0.175g of CB and 28g of deionized water, and stir with a high-speed mixer to form a uniform suspension. At a temperature of 65°C, slowly pour the CB suspension into the INR solution while stirring, and keep stirring for 23 minutes to obtain a CB@INR mixture. After removing the excess moisture layered out of the mixture material obtained in the previous step, pour it into a petri dish...
Embodiment 3
[0036]Weigh 28 g of bromobutyl rubber and 1 g of butyl imidazole respectively. At a high temperature of 150°C, the mixture of components was cured in an internal mixer to obtain butyl imidazole-modified brominated butyl rubber INR. Weigh 1.4g of modified bromobutyl rubber INR and 30g of petroleum ether, and mix them for later use. After the mixture has stood at room temperature for more than 4 days, heat it in a water bath for 1 hour, and dissolve the INR with petroleum ether at 65°C to form a uniform mixture. solution to obtain a solution-like modified bromobutyl rubber INR. Weigh 0.135g of CB and 23g of deionized water, and stir with a high-speed mixer to form a uniform suspension. At a temperature of 65°C, slowly pour the CB suspension into the INR solution while stirring, and keep stirring for 25 minutes to obtain a CB@INR mixture. After removing the excess moisture layered out of the mixture material obtained in the previous step, pour it into a petri dish, place it in ...
