Abstract

Water absorbent resin for hygienic materials is prepared by mixing the following raw materials by weight: 40-70 parts of acrylic acid, 30-50 parts of modified starch, 2-10 parts of acrylamide, 2-4 parts of aminoacetic acid, 1-3 parts of talcum powder, 2-6 parts of sodium alginate, 1-3 parts of an initiator, 2-4 parts of mannitol, and 1-2 parts of lactitol. The production raw materials of the invention are simple and low in price, so that the production investment is less, and the produced super water absorbent resin has very high water absorption capacity, and no gelatin phenomenon after water absorption, is high in water absorption speed, low in price, free of pollution, and high in profit, and is suitable for large-scale popularization and application.

Description

Technical field: [0001] The invention belongs to a production process of functional macromolecular materials in fine chemical industry, in particular to a superabsorbent resin. Background technique: [0002] The largest application field of water-absorbent resin is personal hygiene products, such as: baby diapers, women's sanitary napkins, etc. By adding water-absorbent resins to these hygiene products, their liquid retention characteristics can be improved and the amount of liquid leakage can be reduced, making sanitary napkins or diapers more convenient and comfortable to use. However, the common water-absorbing resins currently used in these products have a low water absorption rate and are prone to gel blocking, hindering their water-absorbing function. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a water-absorbing resin for hygienic materials, which has a high water-abso...
