Description

Batching cooling device of sodium polyacrylate high-absorptivity resin Technical Field The utility model relates to the technical field of resin production, in particular to a batching cooling device for sodium polyacrylate superabsorbent resin. Background The sodium polyacrylate superabsorbent resin is an important functional polymer material, and the molecular structure of the sodium polyacrylate superabsorbent resin contains a large amount of carboxyl anions, so that the sodium polyacrylate superabsorbent resin has unique water absorption capacity, can rapidly absorb and lock liquid with hundreds of times or even thousands of times of the weight of the sodium polyacrylate superabsorbent resin, and can still keep good water retention performance under certain pressure. The excellent water absorption and retention properties can be widely applied to the fields of sanitary articles (such as paper diapers and sanitary napkins), agriculture and forestry water retention (soil improvement and seed coating), industrial dehydration (oil-water separation and wastewater treatment) and the like. The sodium polyacrylate superabsorbent resin mainly comprises core raw materials such as acrylic acid, sodium hydroxide, a cross-linking agent, an initiator and the like, and auxiliary agents such as a dispersing agent, a salt-tolerant modifier and the like, wherein the accurate proportioning and full mixing of the components are key to realizing the optimization of the resin performance. However, in the process of batching, after the acrylic acid is mixed with each auxiliary agent, the temperature of a reaction system can be quickly increased along with the action of an initiator.
