preparation example Construction
[0076] The preparation method of the solid tire tread compound is as follows:
[0077] In the first step, natural rubber, zinc oxide, stearic acid, carbon black, plasticizer, and anti-aging agent are mixed in an internal mixer. After the temperature reaches 150 °C, the rubber is discharged to obtain a section of mixed rubber, which is parked for one day.
[0078] In the second step, a section of the mixed rubber, accelerator, and vulcanizing agent is mixed on an open mill, and after mixing, the pieces are put out and parked for one day to obtain a solid tire tread compound.

[0080] formula:
[0081] 100 parts of natural rubber, 5 parts of Eucommia rubber, 20 parts of styrene-butadiene rubber, 20 parts of cis-butadiene rubber, 8 parts of zinc oxide, 6 parts of stearic acid, 70 parts of carbon black, 10 parts of aromatic oil, 4 parts of antioxidant MB, accelerator 3 parts of CZ, 3 parts of sulfur, 5 parts of OP-10, 0.4 parts of DBD, and 0.3 parts of anti-scorch agent CTP;
[0082] Craft:
[0083] First, the eucommia rubber was masticated on a high-temperature open mixer (80°C) for 5 minutes. At the same time, the natural rubber was masticated in an internal mixer, and a peptizer was added. The mastication temperature was 150°C, the rotational speed was 60rpm, and the mastication time was 3min;
[0084] Adjust the speed of the internal mixer to 40rpm, put the masticated natural rubber, eucommia rubber, styrene-butadiene rubber, and butadiene rubber into the internal mixer for mixing, and the mixing time is 80s; then adjust the speed of the internal...
