Embodiment 1
[0030] 1) The rubber compound formula consists of the following components in mass parts: 100 parts of natural rubber, 50 parts of N115 carbon black, 3 parts of stearic acid, 5 parts of zinc oxide, 0.6 parts of accelerator DM, and 1.5 parts of sulfur. After weighing the ingredients according to the formula, the mixing process is carried out according to the national standard. The specific experimental steps are as follows:
[0031] S1: Dry the carbon black raw material in a drying oven before mixing, and place it in a clean environment after drying.
[0032] S2: During mixing, firstly, the operating distance between the two baffles is 200 mm, and the roller temperature is controlled at 70 °C. The rubber is wrapped on the front roller, and the knife is cut twice for 2 minutes. Then adjust the roller distance to 1.65 mm, add stearic acid, cut the knife once during the period, and operate for 2.5 minutes. Add the mixture of sulfur, vulcanization accelerator and zinc oxide, and ...
