[0035]
[0036] In this embodiment, the denominator batching and final batching process of the sizing material preparation method:
[0037] Master refining process:
[0038] 1) Add smoked sheet RSS3# plasticizing rubber, highly dispersed white carbon black, super silane coupling agent, and other masterbatch powders except zinc oxide, press the top bolt to keep
[0039] 2) Raise the top bolt to add carbon black, press the top bolt to raise the temperature of the rubber to 90-120°C;
[0040] 3) Raise the top bolt and add zinc oxide;
[0041] 4) Press the top bolt to heat up the rubber material to
[0042] 5) Press the top bolt to make the rubber Constant temperature mixing Degumming;
[0043] 6) the sizing material is discharged to the lower auxiliary machine mill for pounding glue, and the second mill is cut off for three times, and the second mill is automatically stirred for 1.5 minutes, and the third mill is delivered to go out;
[0044] Final refining process: ...
Embodiment 2
[0048]
[0049] In the present embodiment, the denominator mixing and final mixing process of the compound preparation method are the same as in Example 1

Abstract
The invention relates to an all-steel radial truck tire tread formula rubber compound and a preparation method and a tire thereof. The all-steel radial truck tire tread formula rubber compound comprises the following basic formula composition (by mass): 100 parts of natural rubber, 40.0-60.0 parts of high-dispersion white carbon black, 1.0-10.0 parts of high-structure wear-resistant carbon black,3.0-7.0 parts of super silane, 1.5-4.0 parts of an activator, 1.0-2.5 parts of an anti-aging agent 1, 0.5-2.0 parts of an anti-aging agent 2, 1.0-3.0 parts of an anti-aging agent 3, 2.0-3.0 parts of aplasticizer, 3.0-5.0 parts of an activator zinc oxide, 1.0-2.0 parts of a vulcanizing agent S, 1.0-2.5 parts of an accelerant, 2.0-4.0 parts of a synergist, and 0.1-0.3 part of an anti-scorching agent CTP. In comparison with the prior art, the invention has the following beneficial effects: by use of the tire thread formula, various physical and mechanical properties of the rubber compound and high speed and durability of the tire can meet the requirements of normal use; and the produced tire has excellent fuel consumption and controllability, and has good controllability, low rolling resistance, high mileage and long service life and is fuel-saving and environmentally-friendly in actual truck loading and use process.
Description
technical field [0001] The invention relates to the technical field of production of all-steel radial truck tires, in particular to an all-steel radial truck tire tread formula compound, a preparation method and a tire. Background technique [0002] Tires are an important safety component of automobiles, and the tire industry is one of the important areas of national economic development. The rolling resistance and wet grip performance of tires, related to the environmental protection and safety performance of tires, have been included in the labeling laws of tires by many countries Among them, the rolling resistance of the tire is closely related to the carbon dioxide emission of the vehicle. [0003] Tires have low rolling resistance and low fuel consumption, which can greatly reduce vehicle carbon dioxide emissions. The improvement of the anti-wet skid performance of the tire reflects that the tire does not slip in rainy days, has shorter braking distance and better dama...
