Problems solved by technology

[0004] At present, most of the traditional reactor agitators are Rushton turbine propellers and three-blade PTU propellers. This type of propellers is likely to cause wall hanging and material adhesion to the propellers during the polymerization reaction, which ultimately hinders efficient production and reduces The yield rate affects the economic benefits of the enterprise

Abstract

The invention discloses a stirring reaction device for synthesizing a super absorbent resin. The device comprises a stirring kettle, wherein a stirrer is arranged in the stirring kettle; the stirrer comprises a rotary shaft and blades arranged on the rotary shaft; the each blade has three rotary bending angles, comprising a backward bending angle, an upper rake angle and a blade breaking angle; the backward bending angle means an angle formed by bending the blade around the rotary shaft as the centerof a circle in the horizontal peripheral direction; the upper rake angle means an angle formed by bending the blade in the vertical direction; and the blade breaking angle means a rotating angle formed by rotating the blade through taking a radius as a central shaft, wherein the radius is a radius in a horizontal periphery formed by taking the rotary shaft as the center of the circle.

Description

technical field [0001] The invention relates to a stirring reaction system, in particular to a stirring reaction device for synthesizing superabsorbent resin. Background technique [0002] Superabsorbent resin is a new type of functional polymer material. It has excellent water absorption and water retention functions. It can absorb hundreds of times, thousands of times, and up to 5300 times its own weight. It is difficult to dehydrate even if it is squeezed. , was crowned with the laurels of "super adsorbent". There are many types of superabsorbent resins, and the raw materials and process methods used are also different. The main types are polyacrylates, polyvinyl alcohols, vinyl acetate copolymers, polyurethanes, polyethylene oxides, starch-based copolymers, etc. In addition, there are composite water-absorbent materials blended with rubber. Among the various types mentioned above, polyacrylates are more researched and developed. The reverse phase suspension polymeriza...
