Example Embodiment
[0033] The process of the present invention for producing reclaimed rubber by kneading mechanochemical method is carried out as follows:
[0034] Take the special kneader for a 75-liter four-row synchronous rotor to desulfurize and regenerate the vulcanized rubber of radial tires as an example.
[0035] a. According to the treatment method of the prior art, the waste radial tires are first sorted and broken into rubber powder to form the rubber material for desulfurization.
[0036] b. Mix the above-mentioned rubber compound with chemical additives. The chemical additives include activators, softeners, plasticizers or tackifiers. The weight ratio is as follows:
[0037] Activator: rubber material = 0.2~0.3:100;
[0038] Softener: rubber material = 8~10:100;
[0039] Plasticizer or tackifier: rubber compound = 3~4:100.
[0040] The activator is 420; the softener is pine tar; the plasticizer is rosin.
[0041] Weighing preparation:
[0042] Use 30 mesh radial tire vulcanized rubber p...
