Abstract

The invention discloses a device and a method for continuously producing vulcanization accelerator CBS, belonging to the field of chemical production. The invention includes accelerator M silo, water metering pump, continuous mixing device, M slurry metering pump, cyclohexylamine metering pump, hydrogen peroxide metering pump, sodium hypochlorite metering pump, continuous reaction equipment and related pipelines. Among them: the continuous reaction equipment has four reaction chambers, and each reaction chamber is equipped with an independent stirring device. M slurry and cyclohexylamine enter the first reaction chamber through the metering pump, hydrogen peroxide enters the first to the third reaction chamber respectively through the metering pump, and sodium hypochlorite enters the fourth reaction chamber through the metering pump; Orifice; M slurry pipeline, cyclohexylamine pipeline, hydrogen peroxide pipeline and sodium hypochlorite pipeline are all equipped with flow regulating valve group. The invention is suitable for the continuous production of the vulcanization accelerator CBS, can realize automatic control, has more stable product quality, and avoids the frequent operation process of intermittent production.

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...
