Abstract

The invention relates to starch-based absorbent resin and a preparation method therefor and belongs to the technical field of absorbent resin. The starch-based absorbent resin contains the raw materials in parts by weight: 40-50 parts of potato starch, 30-40 parts of methacrylic acid, 30-40 parts of acrylic acid, 5-10 parts of acrylonitrile, 1-2 parts of methylene-bisacrylamide, 0.5-1.0 part of glycol dimethacrylate, 1-3 parts of potassium persulfate, 1-3 parts of sodium bicarbonate, 80-100 parts of distilled water and 20-30 parts of 10% NaOH. The absorbent resin adopts a natural substance, i.e., the starch as a basic raw material and accordingly has the advantages of environment-friendliness, biodegradability, emission reduction, low cost, easiness in raw material obtaining, and the like. The water absorption power can reach 600g / g to 800g / g.

Description

technical field [0001] The invention relates to a water-absorbing resin and a preparation method thereof, more specifically, the invention relates to a starch-based water-absorbing resin and a preparation method thereof, belonging to the technical field of water-absorbing resins. Background technique [0002] Superabsorbent resin is a new type of functional polymer material, which can absorb water hundreds or even thousands of times its own mass. It will be lost, so it has good water retention capacity, so super absorbent materials play an important role in various industries such as industry, agriculture, and medical care. [0003] Starch grafted superabsorbent resin is a new type of polymer network polymer material containing hydrophilic groups. It has extremely strong water absorption performance. Its products have a wide range of uses. health and other fields. Contents of the invention [0004] The present invention aims to solve the problems of the water-absorbing r...
