Description

A kind of preparation method and application of betaines antibacterial agent
Technical field
The present invention relates to a kind of preparation method and applications of betaines antibacterial agent, belong to field of textiles.
Background technique
With the development of people's modern times environmental protection concept, textile made by natural fiber is comfortable and easy to wear with its, it is renewable, It is readily biodegradable etc. and to be liked.However, due to containing on natural fiber macromolecular structure chain, there are many amino (- NH2), carboxyl The hydrophilic radicals such as (- COOH), hydroxyl (- OH), easily absorb human body secretion, thus for microorganism growth and breeding provide it is good Good environment.The microorganism bred on the fabric can not only reduce textile quality and physical property, and being more likely to can be strong to human body Health generates harm.Therefore, antibiotic finish is carried out to fabric, with the ability for inhibiting or killing the microorganisms such as bacterium, it appears It is particularly important.
Currently, the antibacterial finishing agent for fabric can be divided into dissolution type (metal class, antibiotic according to stripping property difference Deng) and non-dissolving type (quaternary ammonium salt, chitosan, polymerizing cationically, antibacterial peptide etc.) two major classes.Dissolution type (metal class, antibiotic Deng) antibiotic fabric by its slow release antibacterial agent reach into ambient enviroment it is antibacterial or sterilization purpose.However as using The increase residual antibacterial agent on the fabric of washing times more comes fewer, and the antibacterial activity of fabric gradually decreases and final funeral completely It loses, a small amount of remaining antibiotic is not enough to kill bacterium, can cause the formation of drug resistance and biological mocromembrane instead.And nanometer Ag+ There are still larger disputes in terms of cytotoxicity and genetoxic.
Non-dissolving type quaternary ammonium salt antibacterial agent high water solubility, easily elution directly and the combination of fiber and insecure need pair Fabric is pre-processed, so that fabric feeling is deteriorated and yellowing discoloration, and quaternary ammonium salt antibacterial agent is it is verified that can make bacterium Drug resistance is generated, antibacterial effect durability is not strong;Antibacterial peptide can interfere with the divalent cation-exchanged on cell membrane, to destroy Cytoplasma membrane reaches bactericidal effect.CN201510595396.3 handles wool fabric with antibacterial peptide, makes antibacterial peptide using glutaraldehyde In the surface-crosslinked of wool fabric, to obtain antibacterial wool fabric.But waste water produced during the preparation process is to environment nocuousness, to water Body generates pollution, and influence of the antibacterial peptide vulnerable to enzymatic hydrolysis, and to salt density value, stability is poor.
For glycine betaine as a kind of zwitterionic compound, hydrophilicity is good, the equally distributed yin with equimolar quantity Ion and cation group can resist bacterial adhesion, and prevent the formation of biological mycoderm, and bacterium is inhibited to increase breeding.Meanwhile It also has stronger thermal stability, chemical stability, biocompatibility and no cytotoxicity, is a kind of more satisfactoryization Antibacterial agent.CN201010116533.8 is prepared for a kind of organosilicon sulfobetaines antibacterial agent, but type siloxane glycine betaine Poor storage stability is easy to self-solidifying, and reactivity is poor, forms Covalent bonding together at high temperature with fabric, has damaged fabric Physical mechanical property.CN201580001138.6 develops the azochlorosulfonate propyl lycine antibacterial agent of terminal isocyanate, but it is made Standby complex process, cost of material are high, it is difficult to industrial application.Meanwhile above-mentioned prepared betaines antibacterial agent is all short chain The glycine betaine of small molecule, can not penetrate bacterium film layer, and willful murder bacterium is ineffective.CN201711472560.7 by glycine betaine monomer with Maleic anhydride is polymerize, and obtains the betaine polymer of macromolecular, then the carboxylic acid group generated by maleic anhydride hydrolysis with Hydroxyl reaction on cellulose fibre molecule is grafted on cotton fabric in a manner of covalent bond.Gained betaine polymer antibacterial agent The cell membrane of particle-bound bacteria is penetrated, so that cellular content be made to flow out, kills bacterium, good anti-bacterial effect.But due to the glycine betaine There is extremely more acidic carboxypolymers, the fabric yellowing after arrangement is serious, and the Physical Mechanical energy loss of fabric on polymer macromolecule Hurt larger, causes fabric strength decline serious, be not able to satisfy and take requirement, practical value is little.So how to overcome anti-at present The shortcomings that microbial inoculum exists as previously discussed, a new class of curable, long-term effect of developmental research do not damage fabric property, to human body The antibacterial agent for not generating toxic side effect becomes the urgent need of fabric functionalization development.
Summary of the invention
The shortcomings that in order to overcome current antibacterial agent to exist as previously discussed, the present invention construct a kind of with betaine structure Macromolecule polyalcohol antibacterial agent.The outer membrane of microbial cell is semi-permeable membrane, is made of fat deposit and protein, is for inside and outside two layers Protein, middle layer are fat, therefore to permeate microbial cell kill bacterium and need antibacterial agent while having amphipathic property.Cause This ideal textile antibacterial agent should be that one kind is provided simultaneously with hydrophilic radical and hydrophobic grouping, and can be straight with active group on fabric Connect the macromolecular antibacterial agent of bonding.The present invention response type functional group in a manner of covalent bond securely with fabric macromolecular chain Bonding introduces unsaturated tertiary amine monomers, acrylate monomer, crosslinkable monomers and prepares betaines antibacterial agent, and it is lasting to obtain Antibacterial activity.
