Abstract

The invention discloses a preparation method and device of polyvinyl chloride (PVC) plastic dipping fluid. The preparation method comprises the following steps: (1) weighing the following components in parts by weight: 20-30 parts of neoprene latex, 90-120 parts of PVC paste resin, 30-40 parts of calcium carbonate, 0.5-8 parts of a de-foaming agent, 0.2-5 parts of a stabilizer, 8-10 parts of a viscosity reducer, 0.5-2 parts of an emulsifying agent, 12-15 parts of pigments, 1-3 parts of an anti-ultraviolet agent and 2-8 parts of zinc oxide; (2) adding the weighed neoprene latex, de-foaming agent, stabilizer, viscosity reducer, emulsifying agent, anti-ultraviolet agent and zinc oxide in the step (1) into a stirring kettle and stirring for 0.5h-1h; and (3) adding the weighed PVC resin, calcium carbonate and pigments in the step (1) into the stirring kettle and stirring for 1h-2h under an ultrasonic condition to obtain the PVC plastic dipping fluid. On one hand, the plastic dipping fluid with high quality can be prepared; and on the other hand, the preparation cost can be saved.

Description

technical field [0001] The invention relates to a preparation method and device of polyvinyl chloride dipping solution. Background technique [0002] The compensation chain is generally used in elevators. Its structure is an iron chain wrapped with PVC rubber composite material. It is used to compensate the weight of the steel wire rope to make the elevator run smoothly. [0003] In order to make the elevator run safely and smoothly, and to achieve the effect of quietness and comfort, it is usually necessary to perform noise reduction processing on the compensation chain. The commonly used method is to carry out dipping treatment on the surface of the chain. The dipping compensating chain is mainly formed by dipping the surface of the compensating chain with a dipping liquid, and the dipping liquid is plasticized on the surface of the compensating chain. During the preparation of the dipping solution, various raw materials need to be added into the reactor in batches for st...
