Abstract

The invention provides an anti-microbial deodorizing super absorbent resin compound which comprises a pre-crosslinked acrylic polymer. In parts by weight, 0.5-20 parts of plant antibacterial agent isjointed in 100 parts of pre-crosslinked acrylic polymer; a cross-linking agent is used for treating the surface of the pre-crosslinked acrylic polymer; the plant antibacterial agent is prepared from the following materials by weight percent: 20%-35% of tea leaves, 30%-45% of folium artemisiae argyi and 25%-45% of leonurus. A method of combining the pre-crosslinked acrylic polymer with the plant antibacterial agent includes the following steps: jointing the plant antibacterial agent in the pre-crosslinked acrylic polymer; or bonding the plant antibacterial agent on the surface of the pre-crosslinked acrylic polymer by adopting a cross-linking solution for performing surface thermo-crosslinking treatment; adopting the cross-linking solution for performing surface thermo-crosslinking treatment on the pre-crosslinked acrylic polymer at 70-180 DEG C, thereby acquiring the super absorbent resin compound.

Description

technical field [0001] The invention belongs to the research field of functional superabsorbent resins, in particular to a superabsorbent resin with antibacterial and deodorizing functions. Background technique [0002] Super absorbent polymer (SAP) is a general term for polymers with high water absorption and water retention properties. In foreign countries, in the early 1950s, Goodrich Corporation of the United States developed cross-linked polyacrylic acid resins, and then Russell et al., the Northern Research Center of the United States Department of Agriculture, began to study the grafting technology of starch and acrylonitrile in 1961; by 1978, Sanyo, Japan Chemical Industry Co., Ltd. develops and industrializes the production of starch-grafted polyacrylic acid copolymerized superabsorbent resin. In China, the research on superabsorbent resin started in the early 1980s. Due to objective factors such as late start and short development time, the innovation ability and ...
