| titleOfInvention | Preparation method for reducing porosity of tire tread rubber |
| abstract | The invention belongs to the technical field of rubber tires, and particularly relates to a preparation method for reducing the porosity of a tread rubber of a tire. The preparation method comprises the following steps: (1) mixing polyisoprene rubber with a side chain containing a trans-azobenzene group, carbon black, zinc oxide, stearic acid, an accelerator, an anti-aging agent, sulfur and an anti-scorching agent in an internal mixer to obtain a rubber compound; (2) extruding the rubber compound through an extruder to prepare a tire tread; (3) the tire tread is placed under an ultraviolet lamp for irradiation. The preparation method provided by the invention does not need to change a rubber banburying process, the steps are easy to operate, cis-trans configuration transformation is generated by using trans-azobenzene groups on the side chain of the polyisoprene rubber under the irradiation of an ultraviolet lamp, so that molecular chains move and are arranged more tightly, the porosity of the tread rubber is reduced, the reduction of the porosity is reduced, the mechanical properties of the rubber material such as tensile strength, elongation at break, tearing strength and abrasion are favorably improved, and the service life of the tread rubber is effectively prolonged. |
