Abstract

The invention discloses a preparation method of a super absorbent resin. The preparation method of the super absorbent resin comprises (1) preparing acrylic acid, functional monomers, initiator, crosslinking agent and water-absorbent auxiliaries; (2) dispersing, by weight part, 35-85 parts of the acrylic acid into 20-40 parts of deionized water to obtain an acrylic acid solution; (3) dropwise adding alkaline solution into the acrylic acid solution to obtain a neutralized acrylic acid solution with a degree of neutralization of 30-85%; (4) sequentially dispersing the functional monomers, the initiator, the crosslinking agent and the water absorbent auxiliaries into the neutralized acrylic acid solution, and stirring the mixture for 5-20 minutes; (5) transferring the solution obtained in thestep (4) in an air-insolated mode to a container for standing for 3-5 hours to obtain a jelly, during which the temperature for standing is 50-90 DEG C; (6) drying and cracking the jelly obtained inthe step (5), screening out 20-140-mesh powder to obtain the super absorbent resin.

Description

technical field [0001] The invention relates to the field of polymer material preparation, in particular to a preparation method of superabsorbent resin. Background technique [0002] At present, superabsorbent resin, as a new type of functional polymer material, is widely used in various fields of life and industry, such as medicine and health, agriculture, forestry and horticulture, and desert control. Since the early 1980s, superabsorbent resins have been used in physiological and hygienic materials as absorbent carriers for artificial body fluids, among which, the most used absorbent resins are used in baby and women's sanitary napkins. Among them, 80%-85% of the output is used in sanitary products as the main absorbent material for human body fluids, especially urine. [0003] At present, the superabsorbent resin is mainly produced by the aqueous solution polymerization method, but in the solution polymerization method, it is easy to polymerize instantaneously when it ...
