Macromolecular water-based paint reaction kettle based on liquid floating

Abstract

The invention provides a macromolecular water-based paint reaction kettle based on liquid floating, and relates to the technical field of macromolecular paint. The macromolecular water-based paint reaction kettle based on liquid floating comprises a tank body, a fixed shaft is fixedly installed in the tank body, a spiral groove is formed in the periphery of the fixed shaft, the periphery of the fixed shaft is sleeved with a rotary drum, the bottom end of the rotary drum is in transmission connection with a first motor, a sliding groove is formed in the left side of the rotary drum, and a connecting rod is slidably connected into the sliding groove. According to the macromolecular water-based paint reaction kettle based on liquid floating, a scraping plate can spirally rotate downwards, theoccupied space is reduced, outflow of materials is facilitated, and the cleaning effect is improved; and upper stirring blades can move upwards to increase the stirring area, the higher the rotatingspeed is, the higher the upper stirring blades ascend, materials at the bottom can be intensively stirred at a low speed, more energy is saved, and the stirring effect and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of polymer coatings, in particular to a liquid-floating polymer water-based coating reactor. Background technique [0002] Water-based paint is a paint that uses water as a solvent or as a dispersion medium. It is a relatively new type of paint in the paint market, including water-soluble paint, water-diluted paint, and water-dispersible paint. Water-based paint uses water-soluble resins as film-forming materials. Materials, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins and inorganic polymer water-based resins, etc. Water-based coatings have excellent non-stick properties and durability. [0003] However, during the production of polymer water-based coatings in the reactor, as the reaction proceeds, the viscosity of the system increases rapidly, and the existing stirring device cannot stir it well, which affects its r...

Problems solved by technology

[0003] However, during the production of polymer water-based coatings in the reactor, as the reaction proceeds, the viscosity of the system increases rapidly, and the existing stirring device cannot stir it well, which affects its reaction and efficiency. After the production is completed, due to the high viscosity, it is easy to stick to the inner wall of the reactor, which is not convenient for cleaning. However, the traditional scraper is attached to the vertical inner wall of the reactor for scraping, which not only occupies a large The space inside the reactor can only be scraped off and cannot be transferred downwards
