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...
