Use after-effect rapid vulcanization accelerator.
Use as a quick after-effect vulcanization accelerator, long scorching time, good operation safety
It is used as a aftereffect vulcanization accelerator, with low activity, large deductility, short vulcanization time, excellent scorch resistance, safe processing, easy to disperse, no frost spraying, slight discoloration, and suitable for natural rubber and synthetic rubber. Mainly used in the manufacture of industrial rubber products such as tires, hoses, rubber shoes, and conveyor belts.
production method | The accelerator M is added to the morpholine aqueous solution, and sodium hypochlorite is added dropwise at 23-56°C for oxidation reaction to obtain the semi-finished product, and then filtered, washed with water, and dried to obtain the finished product. Raw material consumption (kg/t) accelerator m (97%) 840 morpholine (60%) 700 chlorine (95%) 478 caustic soda (40%) 4251 sulfuric acid (95%) 1170 |
