Study on Preparation and Properties of Rubber Blends Based on Nitrile Butadiene Rubber and Chloroprene Rubber

摘要

>In this work, nitrile butadiene rubber (NBR)/chloroprene rubber (CR) blends were prepared and investigated. The results showed that NBR and CR in the NBR/CR (50/50) blend were partially compatible. This blend had a relatively regular and compact structure, which improved the mechanical properties as well as the weather resistance, thermal stability, and oil, grease resistances. At the DLH compatibilizer content of 1% (made from Cashew nut shell liquid) or D01 (made from Tung oil), the materials possess better mechanical and physical properties due to much more regular and compact structure. NBR/CR blends can be potential materials for industrial applications which demand high oil and grease resistance and good weather resistance as well as good thermal stability.
