Problems solved by technology

[0014] In summary, at present, in the known technical field, the antibacterial effect is mainly achieved by adding nano-silver ions or quaternary ammonium salt ions, but the above-mentioned method is used in personal daily necessities for women and children, which may cause potential safety hazards, which may cause harm to the user's health. Harm, there is no inquiry about the high antibacterial and deodorizing superabsorbent resin made of tea as a natural functional additive. Based on this, the present invention provides a pure natural superabsorbent resin with high antibacterial and deodorizing functions , the superabsorbent resin maintains high water absorption rate, high water retention rate, high absorption rate and high pressure resistance performance, and at the same time, it provides safe, comfortable and healthy products for women and children

Abstract

The invention discloses antibacterial and deodorant high-water-absorbent resin having the formula comprising the following components in parts by weight: 200 parts of acrylic acid, 40-80 parts of sodium hydroxide, 200-300 parts of deionized water, 0.02-2 parts of a beginning cross-linking agent, 4-100 parts of a tea leaf powder or a tea leaf extract, 0.05-0.6 part of an initiator, and 0.2-4 parts of a composite cross-linking agent. The high-water-absorbent resin can be widely applied in hygienic liquid-absorbing products; the added tea leaves and the extract thereof endow the high-water-absorbent resin with excellent antibacterial deodorant properties, and do not affect various absorption properties of the high-water-absorbent resin. The high-water-absorbent resin has the advantages of easily available raw materials, low cost, significant effects, and great economic benefits, social benefits and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of functional water-absorbing resins, in particular to an antibacterial and deodorizing superabsorbent resin and a preparation method thereof. Background technique [0002] Super absorbent polymer (SAP). [0003] It is a general term for high molecular polymers with high water absorption and water retention properties. [0004] In the early 1950s, the Goodrich Company of the United States developed cross-linked polyacrylic acid resins, and then Russell and others at the Northern Research Center of the United States Department of Agriculture began to study the grafting technology of starch and acrylonitrile in 1961; in 1978, Japan’s Sanyo Chemical Corporation developed And industrialized production of starch-grafted polyacrylic acid copolymerized superabsorbent resin. [0005] In China, the research on superabsorbent resin started in the early 1980s. Due to objective factors such as late start and short dev...
