Comprehensive properties of aramid pulp short fiber reinforced tread rubber for agricultural tires
In view of the complex application environment of agricultural tread rubber,the properties of natural rubber/butadiene rubber/styrene-butadiene rubber were improved by adding aramid pulp short fiber master rubber as reinforcing material in this formula,and the influence of its dosage on the properties of rubber was investigated.The results showed that the Mooney viscosity of the mixed rubber first increased and then decreased,the vulcanization time of the mixed rubber was not significantly affected,and the mechanical properties of the rubber were improved.However,the dispersibility was poorer due to too much aramid pulp short fiber master rubber added,and the properties of the mixed rubber decreased.The tear strength increased by 100.14％and the wear volume decreased by 10.59％when adding 3 parts,which was the best dosage.
