摘　　要：用氯丁胶替代天然橡胶隔震支座保护层,以获得更好的抗老化性能。研究其用于隔震支座保护层胶的可行性。结果表明:与天然橡胶保护层相比,氯丁胶保护层胶能在保持与内层胶的黏接不受影响的前提下,热空气老化性能、耐臭氧老化性能更好,但低温性能较差。In order to obtain better aging property,chloroprene rubber(CR)was used to replace the protective layer of natural rubber(NR)isolation bearing.It was studied that the feasibility of using CR for the protective layer of isolation bearing.The results showed that the adhesion strength between CR protective layer and inner layer was basically the same as that between NR protective layer and inner layer.Compared with NR,CR protective layer had better thermal aging property and ozone aging property,worse low temperature performance.
