| The application of carboxyl solution styrene-butadiene rubber (SSBR),nitrile-butadiene rubber (NBR) and high performance rubber additive Nanoprene in the tread compound of wet skid resistance tire was investigated.The results showed that,by using SSBR to replace equal weight of emulsion styrene-butadiene rubber in the tread compound,the Mooney scorch time and t90 of the compound extended,the tensile stress at 300% strain and tear strength of the vulcanizates increased,the wet grip performance was improved,the heat build-up decreased,and the wear resistance was kept unchanged.By adding 20 phr Nanoprene,the Mooney scorch time and t90 of the compound extended,the tensile stress at 300% strain of the vulcanizates increased,the wet grip performance was improved,the heat build up was reduced,and the wear resistance decreased.By adding 5 phr NBR,the curing behavior of the compound,and the physical properties and heat build-up of the vulcanizates changed little,the wet grip performance was improved,and the wear resistance decreased. |
