1. Hardness: consistent with the original formula;

2. Physical properties: The tensile strength and elongation before and after aging decreased slightly, and are at the same level as the original formula. The elongation at break is consistent with the original formula;

3. Abrasion: When the activated rubber powder A is used in the formula less than 15phr, the abrasion performance is excellent. After using 20phr, the abrasion performance decreases slightly;

4. Compression heat generation: When the activated rubber powder A is used in the formula at less than 15phr, it is consistent with the original formula. When 20phr is used, the heat generation increases slightly.


2.4 OTR formula application: verification results (activated rubber powder A: 10-20phr)

Cause analysis and improvement plan: Due to the high filling factor of the formula, the wear performance of the formula decreased slightly and the compression heat generation increased after using 20phr of rubber powder A. The amount of N234 carbon black and white carbon black in the formula can be reduced. It can not only reduce heat generation, improve wear, maintain the performance of the original formula, but also further reduce costs.

Summary: After the activated rubber powder A is applied to the tread formula at 10-15phr, the performance is at the same level as the original formula. After using 20phr, the wear and heat generation performance is slightly reduced, which can be improved by reducing the amount of N234 carbon black and white carbon black in the formula, further reducing costs.


The following conclusions have been drawn after verification:

Cost: After activated rubber powder A is applied to the OTR tread formula at 5-20phr, the quality cost is reduced compared with the original formula: 193.6-714.0 yuan/ton.

Performance: After the activated rubber powder A is applied to the OTR tread formula at 5-15phr, the performance is at the same level as the original formula. After using 20phr, the wear and heat generation performance is slightly reduced, which can be improved by reducing the amount of N234 carbon black and white carbon black in the formula, further reducing costs.
