Embodiment 1
[0020] A rubber vulcanization accelerator, comprising 5 parts of stearyl alcohol, 5 parts of stearic acid, 2.5 parts of ethylene glycol amine, 4 parts of sodium urealate polymer, 10 parts of accelerator D, 7.5 parts of accelerator Agent CZ, 5 parts of anti-scorch agent, 3 parts of sulfur and 6 parts of white carbon black.
[0021] The preparation method of above-mentioned rubber vulcanization accelerator is as follows:
[0022] (1) Put 50kg of stearyl alcohol, 50kg of stearic acid, and 25kg of ethylene glycol amine into a 500-liter reaction pot, and heat to 125°C under stirring to form a uniform liquid;
[0023] (2) Put the above liquid into a mixing pot, gradually add 100kg of accelerator D and 75kg of accelerator CZ under heating, 50kg of anti-scorch agent CTP, 30kg of sulfur and 40kg of sodium urealate polymer, and the temperature is controlled at 105°C. After mixing evenly, gradually add 60kg of white carbon black, and discharge after mixing.
