Relating to the rubber field, the invention discloses a production technology for chloroprene rubber. The technology comprises the processes of: rubber drying, plastication, mixing, semi-finished product cutting and vulcanization. According to the method, by strictly controlling the rubber drying temperature and time in the rubber drying process, the quality of the dried rubber material is improved. The mixing process adopts a two-stage mixing process, well controls the mixing time and discharge temperature, so that scorching phenomenon of chloroprene rubber is significantly reduced, and the rubber guiding, discharge and batch-out of an open mill are smooth, and no roll sticking phenomenon appears. The vulcanization process adopts N-tert-butyl-2-bisbenzothiazole sulfenamide as a vulcanization accelerator, which is safe and pollution-free and has no harm to the human body. The technological process adopts a drum type vulcanizing machine, the vulcanization efficiency and quality are greatly improved, and the produced product has high Mooney viscosity and good quality. The technological method has the advantages of good technology, simple operation, and good technological stability, thus being suitable for factory automation production.
