High activity biological super-strong water absorption resin and preparation method thereof

Abstract

The invention provides a high-activity biological super strong water absorbing resin, the process for preparation comprises adding acrylic acid in a catalyst case according to quality portion, adjusting the pH value to 5-7, and adding a certain amount of maize starch, inorganic mineral substance, cross linker solution and initiating agent in turn, evenly stirring, warming up to 35 to 45 DEG C, polymerizing for 1.5-2 hours, stopping stirring when the system takes semitransparent gel shape, continuously warming up to 55-70 DEG C to polymerize 1-2 hours again till the system is turned to be gelatin, taking granulations out, drying, grinding to be half-finished product, and adding cross linker solution whose half-finished product quality is 0.01-1% and 0.01-1% high-activity biological agent, evenly stirring, placing in a drier, warming up to 60-100 DEG C to have a secondary treatment of surface cross bonding, and getting high-activity biological super strong water absorbing resin. The strong water absorbing resin product has the advantages of fast water absorbing speed, strong water absorbing capability, excellent anti adhesive properties after absorbing water, and which has the functions of resisting bacterium, absorbing osmyl, health care and the like, and can be applied in the production of women sanitary napkins, paper diaper, the aged health shorts and the like.

Description

technical field

[0001] The invention belongs to the technical field of macromolecules, and relates to a polymer water-absorbing resin, in particular to a high-activity biological super water-absorbing resin and a preparation method thereof. The high-activity bio-superabsorbent resin of the present invention is mainly used in the production of household paper such as sanitary napkins, paper diapers, and health care shorts for the elderly. Background technique

[0002] Polymer water-absorbing resin is a new type of polymer functional material developed in recent years. Due to its strong water absorption, it has been widely used in industry, agriculture, medical treatment and daily life. Super-absorbent resin, due to its super water-absorbing capacity (it can absorb water hundreds or even thousands of times its own weight), has been widely used in household paper, especially in the production of sanitary napkins and diapers for women. .
