Abstract

The invention discloses a reaction system and method for batch production of chlorinated polyvinyl chloride. The reaction system mainly includes a liquid chlorine vaporizer, a chlorine gas buffer tank, an activation reactor and a chlorination reactor. A chlorine buffer tank is connected, and an activation reactor is connected to the chlorination reactor. The reaction system of the present invention is not only suitable for the gas-solid phase chlorination reaction of polyvinyl chloride, but also suitable for the gas-solid phase chlorination reaction of other powders. It can not only be used as a chlorination reaction system alone, but also can be combined with other chlorination systems. Used together, it has good flexibility of use. The reaction system and method for intermittently producing chlorinated polyvinyl chloride of the present invention are low in cost, high in product quality, easy to control in operation, high in energy utilization rate, reduced in production cost, and can increase the chlorine content in chlorinated polyvinyl chloride to 65%. above.

Description

technical field

[0001] The invention belongs to the field of industrial production of chlorinated high polymers, and relates to a system and method for intermittently producing chlorinated polyvinyl chloride. Background technique

[0002] Chlorinated polyvinyl chloride (CPVC) is a new type of engineering plastic obtained by chlorinating and modifying polyvinyl chloride (PVC) resin. After the PVC resin is chlorinated, the irregularity of the molecular chain arrangement increases and the polarity increases, which increases the solubility and chemical stability of the resin, thereby improving the heat resistance of the material and resistance to acids, alkalis, salts, oxidants, etc. corrosion performance. The mechanical properties of the heat distortion temperature of the resin are improved, the chlorine content is increased from 56.7% to 61-69%, the Vicat softening temperature is increased from 72-82°C to 90-125°C, the maximum service temperature can reach 110°C, and the long...
