Description
Technical field
The present invention relates to a kind of preparation method, belong to high molecular polymer based composites field with bacteriostasis property water-absorbing resin.
Background technology
Chitosan is as a kind of Nantural non-toxic, good biocompatibility, and degradable, the renewable and profuse resource of originating has caused day by day that people pay attention to, and has been successfully applied to a plurality of fields such as medicine.
The different molecular weight chitosan is different to the restraining effect mechanism of different microorganisms:
(1) for Gram-negative bacteria (intestinal bacteria), mainly be because micromolecular chitosan penetrating enters in the microorganism cells, electronegative tenuigenin in the adherent cell, and throwing out takes place, and upset the normal physiological activity of cell, thus kill bacteria;
(2) to gram-positive microorganism (staphylococcus aureus), mainly be, form one deck polymeric membrane, stoped nutritive substance in cell, to transport, until bacterium death because macromolecular chitosan is adsorbed on the surface of microorganism cells.
Chitin is one of the abundantest natural organic-compound of occurring in nature, it is next in number only to Mierocrystalline cellulose, simultaneously it still is the nitrogenous natural organic-compound of quantity maximum outside the isolating protein on the earth, almost there is 8% material to be rich in chitin in the water globe product organism, comprise shrimp, crab, squid, oyster and inkfish etc., the annual chitin that produces of sea leave surpasses 8,000 ten thousand tons, and these oceanic resources of development and utilization have crucial meaning.The product chitosan of de-acetyl chitin; chitosan is made up of most of D-glucosamine and minor N-acetyl-D-amino glucose; be that its similar is in Mierocrystalline cellulose with the straight-chain polysaccharide that β-(1,4) glycosidic link has connected; chitosan is because of its distinctive molecular structure; be the alkaline glycosaminoglycan of only a large amount of existence in the natural polysaccharide, chemical property is more active, is easy to carry out number of chemical and modifies; and be dissolved in acidic aqueous solution, have excellent biological compatibility and biodegradability.Chitosan is because have a protonated ammonium, can with the cytolemma effect of bacterium negative charge, disturb the bacterial cell membrane function, cause bacterial body inner cell matter to run off, upset the normal physiological metabolism of cell, thereby reach germ-resistant purpose.
(patent publication No.: CN101559234A) aspect the at present domestic water-absorbing resin that has bacteriostasis property in preparation, be by water absorbing resin particle being added in the dispersion liquid that contains silver ions, zine ion, titanium oxide and composition thereof, stirring is left standstill, and drying becomes the matrix material that contains antiseptic-germicide.This kind contains the silver ions matrix material because silver ions water-soluble, when running into water soluble in water in and be not attached to the water-absorbing material surface; Need under the photochemical catalysis condition, just possess antibacterial for zine ion, titanium oxide matrix material.The present invention is that antibacterial material is in the water-absorbing material all the time with chitosan graft vinylformic acid synthetic resins, and the product that possesses biocidal property and water absorbing properties just becomes emphasis of the present invention.
