Improve all-steel load-carrying radial tire body rubber material and mixing method thereof

[0029] Example 1, an improved all-steel radial truck tire carcass compound, the proportion is by weight, and its components include 100 parts of natural rubber, 46 parts of carbon black N326, 1 part of optimized antioxidant 4020, and antioxidant TMQ 0.9 Parts, 4.5 parts of insoluble sulfur 7020, 1.25 parts of accelerator DZ, 0.2 parts of anti-scorching agent CTP, 5 parts of adhesive RA65, 3 parts of adhesive GLR, 8 parts of active agent, 15 parts of white carbon black.

[0030] The active agent is nano zinc oxide, and the particle size of the nano zinc oxide is 20-80 nm.

[0031] The optimized antioxidant 4020 is an organic complex of N-(1,3 dimethylbutyl)-N'-phenyl-p-phenylenediamine.

[0032] The antioxidant TMQ is 2,2,4-trimethyl-1,2-quinoline dihydroxide polymer.

[0033] The above-mentioned method for mixing the carcass compound includes the following steps:

[0034] 1. One stage mixing: control the temperature of the internal mixing chamber of the internal mixer to 35°C, and the rot
