Abstract

The invention discloses tread base for an all-steel radial tire and a preparation method thereof. The tread base for the all-steel radial tire comprises the following compositions in weight portion: 100 weight portions of natural gum SMR20, 0.1 to 0.5 weight portion of chemical peptizer, 30 to 45 weight portions of carbon black, 7 to 15 weight portions of white carbon black, 3 to 5 weight portions of zinc oxide, 1.5 to 3 weight portions of silane coupling agent Si-69, 1.5 to 3 weight portions of stearic acid, 1 to 2 weight portions of antiaging agent 4020, 0.5 to 2 weight portions of micro-crystalline wax, 0.5 to 2 weight portions of antiaging agent RD, 1 to 2 weight portions of fatigue protective agent G-108, 2 to 3 weight portions of oil-filled insoluble sulfur, 0.5 to 1 weight portion of accelerant NS, 0.5 to 1 weight portion of accelerant CZ and 0.1 to 0.5 weight portion of antiscorcher CTP. The tread base for the all-steel radial tire is prepared by one-stage mixing, standing for the first time, two-stage mixing, standing for the second time and final mixing.

Description

technical field [0001] The invention discloses an all-steel radial tire tread base rubber, and also discloses a preparation method of the all-steel radial tire tread base rubber. Background technique [0002] At present, many tires undergo high-strength flexure at the base of the tread during high-speed driving with heavy loads, resulting in high heat generation at the base of the tread, which causes quality problems such as crown detachment and shoulder emptying of the tire, and seriously affects the service life of the tire. , and even cause major traffic accidents. Contents of the invention [0003] One of the purposes of the present invention is to overcome the deficiencies in the prior art and provide a tire that can reduce the heat generation at the base of the tread during high-speed driving, avoid quality problems such as tire crowning and shoulder voids, and improve tire use. Long life base tread compound for all steel radial tires. [0004] The second object of...
