胶料配方和贮存湿度对冻干胶塞吸附性能的影响

从胶料配方和贮存湿度两方面研究丁基橡胶冻干胶塞（简称胶塞）的吸附性能。结果表明：高湿度贮存条件下胶塞水分含量迅速增长；3种胶料配方的胶塞中，比表面积最大的胶塞吸附速率最大，阻水能力最弱，说明其水汽渗透率高，应避免选用此种胶料配方胶塞。;The adsorption properties of isobutylene-isoprene rubber freeze-dried rubber plugs were studied from two aspects of compound formulation and storage humidity. The results showed that the misture content the rubber plug rapid increased in high humidity storage environment. Among three rubber plugs with different compound formulation，the one with the largest specific surface area had the highest adsorption rate and the weakest water blocking capacity，indicating that the water vapor permeability was high，and should be avoided to use rubber plug with this compound formulation
