Plasticisation of Carbon Black Filled Acrylonitrile-butadiene Rubber Using Cardanol

摘要

The comparative performance of cardanol,the main ingredient of cashew nut shell liquid(CSNL)for plasticising carbon black-filled acrylonitrile-butadiene rubber(NBR)is presented.The performance of dioctyl phthalate(DOP),a common plasticiser for NBR was compared with that of cardanol in terms of the cure characteristics,mechanical properties,thermal ageing properties,crosslink density and extractability.While both these plasticisers showed almost equivalent performance in respect of most properties,a clear superiority was noted for cardanol in the case of extractability after varying periods of ageing at 100°C.This alludes to the resistance of cardanol-plasticised NBR to ageing and a lessened possibility of it being leached out/blooming out on prolonged use.The demonstrated usefulness of cardanol,a renewable,agro-byproduct for NBR processing is significant.
