摘　　要：高性能天然橡胶在实际生产应用中会出现贮存硬化的现象,导致了原本高性能的丧失,这一问题亟待解决。近年来研究报道了2-巯基苯并噻唑(MBT)可作为一种新型恒粘剂用于天然橡胶的恒粘处理,而关于MBT对臭氧老化性能的影响目前仍处于空白。通过加速贮存实验研究MBT对高性能天然橡胶的恒粘效果,并通过臭氧老化实验研究MBT的添加对高性能天然橡胶耐臭氧老化性能的影响。结果表明,利用MBT可制备具有较好恒粘效果的高性能天然橡胶;MBT的加入在一定量的范围内能提高橡胶的耐臭氧老化性能。A storage harden phenomeno n in the actual production would result in the loss of the original high performance natural rubber. It is reported that 2-Mercaptobenzothiazole（ MBT） could be used as a kind of new adhesive in the constant viscosity treatment for natural rubber, meanwhile the effect of MBT on the aging properties of ozone is still unknown. In this paper, the effect of MBT on the high performance natural rubber was studied by accelerated storage tests. The effect of MBT addition on the aging resistance of high performance natural rubber was studied by ozone aging tests. The results showed that high performance natural rubber with good constant viscosity effect could be produced by using MBT; The addition of MBT could improve the aging resistance of rubber in a certain range.
