Description

Technical Field

[0001] This utility model relates to the field of resin production technology, and in particular to a mixing filler device for highly absorbent resins. Background Technology

[0002] Superabsorbent polymers (SAPs), an important class of functional polymer materials, are typically produced by reacting hydrophilic monomers with fillers, enabling them to absorb tens or even thousands of times their own weight in water. The fillers serve to increase the water absorption rate and significantly enhance the water absorption capacity. Commonly used fillers fall into two categories: inorganic fillers such as kaolin, diatomaceous earth, and montmorillonite, and organic fillers such as starch and cellulose. These fillers not only enhance the resin's water absorption capacity but also give the product good biocompatibility and biodegradability.

[0003] In the industrial production process of superabsorbent polymers, after the filler pretreatment is completed, the filler needs to be added to the reaction system at an appropriate time, and the filler and resin raw materials should be thoroughly mixed by means of mechanical stirring. After the filler is uniformly dispersed, the reaction is then carried out according to the standard polymerization process for superabsorbent polymers. In actual production, due to the differences in the physical properties of the filler itself, it is difficult to mix it uniformly with the resin raw materials during the stirring process.
