Abstract: |
The waste tire rubber powder was regenerated by vulcanizing machine,and the influence of desulfuration temperature,time and pressure on the Mooney viscosity and physical properties of reclaimed rubber powder was studied. The results showed that,as the desulfuration temperature increased,the Mooney viscosity of the reclaimed rubber decreased,and the tensile properties of the vulcanized reclaimed rubber increased at first and then decreased. As the desulfuration time was extended or pressure increased,the Mooney viscosity of the reclaimed rubber decreased,and the tensile properties of the vulcanized reclaimed rubber decreased. When the desulfuration temperature was 250 ℃,the desulfuration time was 10 min,and the desulfuration pressure was 2. 5 MPa,the overall properties of the reclaimed rubber were better. |
