Embodiment 1
[0041] Example 1 Waste radial tires were washed and air-dried, crushed, and then the rubber particles and steel wires were separated with a centrifugal magnetic separator, and 500 kg of 8-10 mesh rubber (powder) was sieved, and the rubber powder was added to a dynamic desulfurization tank, and at the same time 380 kg of water, 50 kg of tar, 40 kg of 450 rubber activator, 30 kg of diphenyl disulfide and diamyl disulfide (mixture of the two in any proportion), keep the temperature in the tank at 210 ° C, the pressure at 2.2 Mpa, and the reaction time is 2.5 After one hour, the tank is cooled to room temperature, sent to the open mill for refining, the roller line speed of the open mill is 1.3 m / s, and the temperature is 60°C, and then kneading and refining are carried out sequentially under the same conditions to obtain 625 kg of qualified reduced rubber products .
[0042] Above-mentioned tar, 450 rubber activator, diphenyl disulfide and dipentylated disulfide can all be purcha...
Embodiment 2
[0043] Example 2 Waste radial tires were washed and air-dried, crushed, and then the rubber granules were separated from the steel wire by a centrifugal magnetic separator, and 400 kg of 9-12 mesh rubber material (powder) was sieved, and the rubber powder was added to a dynamic desulfurization tank, and at the same time 500 kg of water, 40 kg of tar, 40 kg of 480 rubber activator, 30 kg of dipentyl disulfide and dibenzyl disulfide (the two are mixed in any proportion), keep the temperature in the tank at 220°C, the pressure at 2.0Mpa, and the reaction at 2.0 After one hour, the tank is cooled to room temperature, and sent to the mill for refining. The roller line speed of the mill is 1.1 m / s, and the temperature is 50 ° C. Then, kneading and refining are carried out successively under the same conditions to obtain 515 kg of qualified reduced rubber products. .
Embodiment 3
[0044] Example 3 Waste radial tires were washed and air-dried, crushed, and then separated from the steel wire by a centrifugal magnetic separator, and 600 kg of 11-mesh rubber material (powder) was sieved, and the rubber powder was added to a dynamic desulfurization tank, and 300 kg Water, 40 kg of tar, 40 kg of 480 rubber activator, 20 kg of dipentyl disulfide and dibenzyl disulfide (the two are mixed in any proportion), keep the temperature in the tank at 230 ° C, the pressure at 2.0 Mpa, and react for 2.1 hours. The tank is down to room temperature, sent to the mill for milling, the roller line speed of the mill is 1.3 m / s, and the temperature is 60° C. Then kneading and refining are carried out successively under the same conditions to obtain 605 kilograms of qualified reduced rubber products.
