Problems solved by technology

Existing pneumatic tires are easy to be punctured during use. After being punctured, they are prone to bursting and slow air leakage. Therefore, tires with inner tubes or tubeless tires need to be repaired after being punctured before continuing to drive.
Another kind of tire is a solid tire. A solid tire or a porous solid tire does not need to be inflated, so it will not burst due to a puncture. Although it can continue to drive after being punctured, most solid tires are too heavy and have high hardness. Poor grip and long braking distance limit its application

Abstract

The invention discloses a maintenance-free tire compound, which is composed of the following components measured by weight: natural rubber: 30-70 parts, EPDM rubber: 70-30 parts, carbon black: 5-25 parts, white Carbon black: 45-35 parts, zinc oxide: 2-3 parts, stearic acid: 1-1.5 parts, anti-aging agent: 0.5-1.5 parts, accelerator: 0.1-0.6 parts, sulfur: 0.5-1.0 parts, foaming Agent: 2‑3.0 parts, foaming aid: 1.0‑1.5 parts, super silane: 5‑8% of white carbon black. The sum of the consumption of natural rubber and EPDM is 100 parts. The tire rubber compound of the present invention has the advantages of low compression heat generation, better resilience, and less wear; the present invention uses low heat generation, high grip, and low rolling resistance raw materials, coupled with a reasonable combination of component design, greatly The hidden dangers caused to processors and users in the process of production and use are reduced, and the safety, economy and adaptability of the product are wider.

Description

technical field [0001] The invention relates to tire technology, more specifically, the invention relates to a maintenance-free tire compound and a preparation method thereof. Background technique [0002] Tires are made up of multiple materials. At present, tires generally have inner tube tires or tubeless tires, solid tires or porous solid tires. Existing pneumatic tires are easy to puncture during use, and after the puncture, they are prone to bursting and slow air leakage. Therefore, after the puncture of the inner tube tire or the tubeless tire, it needs to be repaired before continuing to drive. Another type of tire is a solid tire. A solid tire or a porous solid tire does not need to be inflated, so it will not burst due to punctures. Although it can continue to drive after being punctured, most solid tires are too heavy and have high hardness. Poor grip and long braking distance limit its application. Maintenance-free tires refer to tires with inner tubes or tubele...
