Embodiment 1

[0028] Mix 50 parts of natural rubber TSR10, 10 parts of butadiene rubber and 1 part of plasticizer paraffin oil in the mixing chamber for 5 minutes, then add 18 parts of carbon black N115, 10 parts of filler silica, 3 parts of zinc oxide, a vulcanization activator, were kneaded for 5 minutes, then 8 parts of carbon black N115 were added to the mixing chamber and kneaded for 1 minute. During the mixing process, the rotor speed was 45 rpm, the cooling circuit water temperature of the mixing chamber was 45°C, and the rotor cooling circuit water temperature was 35°C.

[0029] Cool the masterbatch obtained in the above steps to room temperature and mix with 14 parts of carbon black N115 and 1 part of anti-aging agent (4010NA) in the mixing chamber for 1 minute, and discharge the glue after the mixing is completed. During the above mixing process, the rotor speed was 45 rpm, the cooling circuit water temperature of the mixing chamber was 45°C, and the rotor cooling circuit water te...

Embodiment 2

[0033]Mix 70 parts of natural rubber TSR20, 10 parts of styrene-butadiene rubber, 5 parts of isoprene rubber and 3 parts of paraffin oil in the mixing chamber for 7 minutes, then add 20 parts of carbon black N121, 18 parts of carbonic acid Calcium, 2 parts of titanium dioxide, and 4 parts of zinc oxide, a vulcanization activator, were kneaded for 7 minutes, then 10 parts of carbon black N1234 were added to the mixing chamber and kneaded for 3 minutes. During the mixing process, the speed of the rotor was 50 rpm, the temperature of the water in the cooling circuit of the mixing chamber was 50° C., and the temperature of the water in the cooling circuit of the rotor was 40° C.

[0034] Cool the masterbatch obtained in the above steps to room temperature and mix with 17 parts of carbon black N326 and 3 parts of antioxidant 4020 in the mixing chamber for 3 minutes, and discharge the glue after the mixing is completed. During the above mixing process, the speed of the rotor was 50 ...

Embodiment 3

[0038] Mix 90 parts of natural rubber TSR10, 20 parts of butyl rubber and 5 parts of plasticizer paraffin oil in the mixing chamber for 10 minutes, then add 23 parts of carbon black N339, 30 parts of filler silica, 5 parts of zinc oxide, a vulcanization activator, were kneaded for 10 minutes, and then 13 parts of carbon black N339 were added to the mixing chamber and kneaded for 5 minutes. After the kneading, the rubber was removed to obtain a masterbatch. During the mixing process, the rotor speed was 55 rpm, the cooling circuit water temperature of the mixing chamber was 55°C, and the rotor cooling circuit water temperature was 45°C.

[0039] Cool the masterbatch obtained in the above steps to room temperature and mix it with 19 parts of carbon black N115 and 1-5 parts of anti-aging agent 3100 in a mixing chamber for 5 minutes, and remove the glue after the mixing is completed. During the above mixing process, the speed of the rotor was 55 rpm, the temperature of the water i...

Abstract

The invention belongs to the technical field of rubber tire processing, and particularly relates to a radial tire and a preparation method thereof. The radial tire provided by the invention is prepared from the following raw materials in parts by weight: 50-90 parts of natural gum, 10-20 parts of synthetic rubber, 30-40 parts of carbon black, 10-30 parts of filler, 1-5 parts of plasticizer, 1-2 parts of resin, 1-3 parts of accelerant, 1-5 parts of scorch retarder, 0.5-2 parts of vulcanizing agent, 3-5 parts of vulcanizing activator and 1-2 parts of anti-aging agent. The radio tire provided by the invention has high rigidity, excellent tear resistance and good wear-resisting property; meanwhile, cracks caused by external environmental factors can be reduced, so that the service life of the tire is prolonged.

Description

technical field [0001] The invention belongs to the technical field of rubber tire processing, and in particular relates to a radial tire and a preparation method thereof. Background technique [0002] According to statistics, China's automobile production and sales exceeded 18 million in 2010, ranking first in the world. According to other data, my country's car ownership has reached 100 million. The forward momentum of my country's automobile industry has directly driven the development of my country's tire industry. At the same time, the huge domestic market potential also attracts international tire giants. The radialization rate of car tires in the Chinese market has reached 100%, and the radialization rate of truck and bus tires is about 70%~80%, while in the field of engineering tires, the radialization rate is only about 4%, compared with 50%~70% in European and American countries. % OTR tire radialization rate, China's OTR tire market has broad prospects. However...
