Application of liquid recycled rubber in conveyor belt covering rubber
Adding two kinds of recycled rubber made by different processes to conveyor belt cover rubber,the effects of different Mooney viscosity reclaimed rubber and its dosage on the performance of conveyor belt cover rubber were investigated.The results show that with the increase of the amount of recycled rubber,the optimum cure time of the mixed rubber becomes shorter,the torque difference becomes smaller,and the Payne effect becomes stronger;the hardness,tensile strength,and percent modulus of the vulcanized rubber decreases,the elongation at pull-off rises,the abrasion resistance decreases,the fatigue temperature rise rises,and the flexibility resistance rises.Liquid recycled rubber Mooney viscosity is low,the torque difference in the vulcanization curve of the mixing rubber has a greater influence,the Payne effect becomes smaller,the tensile strength and elongation increase,abrasion resistance decreases,and the flexural resistance increases.
