Antibacterial odor-removing super absorbent resin and preparation method thereof

Abstract

The invention provides an antibacterial and odor-removing super absorbent resin composite material. The antibacterial and odor-removing super absorbent resin composite material comprises super absorbent resin and an antibacterial and odor-removing combined material compounded on the super absorbent resin, the antibacterial and odor-removing combined material comprises an antibacterial material and an odor-removing material; the antibacterial material comprises polycaproguanidine hydrochloride and / or nano-silver; the peculiar smell removing material comprises 4-ethyl-4-soybean-based ethyl sulfate morpholine and / or zinc diricinoleate. According to the antibacterial odor-removing super absorbent resin composite material with the specific structure and composition provided by the invention, a specific combination of an antibacterial material and an odor-removing material is selected, and part of hydrolyzed polyacrylamide is further selected as a super absorbent resin matrix; therefore, the super absorbent resin composite material with excellent antibacterial and odor-removing properties is obtained. The preparation method provided by the invention has the advantages of simple process, mild conditions, strong controllability, stable raw materials and low process cost, and is more suitable for industrial popularization and application.

Description

technical field [0001] The invention belongs to the technical field of multifunctional super absorbent resins, and relates to an antibacterial and deodorant superabsorbent resin composite material and a preparation method thereof, in particular to an antibacterial deodorant superabsorbent resin and a preparation method thereof. Background technique [0002] Super Absorbent Polymer (SAP) for disposable hygiene products is mainly composed of polyacrylic acid-based synthetic polymers, which are polymerized and moderately cross-linked to form a three-dimensional network by acrylic acid and acrylamide monomers containing strong hydrophilic groups. It can quickly absorb more than ten times or even thousands of times its own mass of water through hydration to form a gel. This kind of material has excellent properties such as large water absorption capacity, fast water absorption rate, strong water retention capacity, non-toxic and tasteless, which is incomparable with general mater...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are also corresponding researches on antibacterial and deodorizing superabsorbent resins, such as selecting acrylic acid as a polymerization precursor, tea powder or tea extract as an antibacterial deodorant, and preparing an antibacterial and deodorizing superabsorbent resin; or using Specific antibacterial and deodorizing superabsorbent resins with core-shell structure, but there are complex raw material components and contents, and the stability of raw materials is difficult to guarantee, which leads to problems such as difficulty in guaranteeing product performance stability, and the preparation process of core-shell structure superabsorbent resins is difficult. , product uniformity and batch stability are difficult

There is also a technical plan to use a compound antibacterial cross-linking agent for surface treatment to obtain a shell-type antibacterial and deodorizing superabsorbent resin with a three-dimensional cross-linked network structure, but there is still a preparation process that requires free radical polymerization, and the process conditions require Primary cross-linking and post-crosslinking treatment processes require high process conditions and high production costs
