Embodiment example 1
[0026] (1) adding epoxidized natural rubber, white carbon black, and aluminum chloride to an internal mixer and kneading for 10 minutes in sequence, and the kneading temperature is 80° C. to obtain a kneaded rubber;
[0027] (2) Vulcanize the obtained mixed rubber at 180° C. according to the positive vulcanization time;
[0028] (3) Crushing the vulcanized rubber into 80-mesh rubber powder, and hot pressing at 180°C for 20 minutes to obtain reprocessed rubber.
[0029] By changing the amount of white carbon black and aluminum chloride added, comparative samples and 5 examples were prepared according to the above-mentioned method of the present invention. The specific formulations of the comparison sample and the embodiment are shown in the following table 1, and the unit of each material consumption in the table is g.
