Study on Preparation of NR/BR Table Tennis Bat Rubber
Table tennis bat rubber was prepared by using natural rubber (NR) and butadiene rubber (BR). The effects of the blending ratio of NR and BR, contents of accelerator and sulfur on the performance of rubber racket were studied. The results showed that when under conditions of 160°C, 10min and 15MPa in the curing press, total amount of material is 100 phr .Including the NR/BR ratio was 0.65/0.35 (wt), the content was 90 phr the accelerator of DM/D ratio was 0.382/0.618, the content was 2.5 phr and the content of sulfur was 2.5 phr, the compound had a high vulcanization rate, an excellent physical and mechanical properties and aging performance.
