Abstract

The invention discloses equipment and a method for continuously producing a vulcanization accelerator CBS, and belongs to the field of chemical production. The system comprises an accelerator M bin, awater metering pump, a continuous mixing device, an M slurry metering pump, a cyclohexylamine metering pump, a hydrogen peroxide metering pump, a sodium hypochlorite metering pump, continuous reaction equipment and related pipelines; the continuous reaction equipment is provided with four reaction chambers, and each reaction chamber is provided with an independent stirring device; M slurry and cyclohexylamine are introduced into a first reaction chamber usingthe metering pumps, hydrogen peroxide is introduced into a first reaction chamber, a second reaction chamber and a third reaction chamber using the metering pump, and sodium hypochlorite is introduced into a fourth reaction chamber using the metering pump; a discharge overflow port is formed in the fourth reaction chamber; and a M slurry pipeline, a cyclohexylamine pipeline, a hydrogen peroxide pipeline and a sodium hypochlorite pipeline are all provided with flow regulating valve banks. The method is suitable for continuous production of the vulcanization accelerator CBS, automatic control can be achieved, the product quality is more stable, and the frequent operation process of intermittent production is avoided.

Description

technical field [0001] The invention relates to the field of chemical production, in particular to equipment and a method for continuously producing vulcanization accelerator CBS. Background technique [0002] Vulcanization accelerator CBS is a slow-acting vulcanization accelerator used in a large amount at home and abroad. It has two advantages of excellent anti-scorch performance and short vulcanization time. It is mainly used in the manufacture of tires, rubber hoses, rubber shoes, electric wires, etc. At the same time, it will not produce nitrosamine carcinogens during the vulcanization process, and is one of the environmentally friendly accelerators commonly used at home and abroad. [0003] At present, the production of the vulcanization accelerator CBS in the industry mainly adopts kettle-type intermittent operations. Due to the frequent operations of feeding, reacting, and discharging due to intermittent reactions, on the one hand, there are large fluctuations in the...
