The present invention relates to a kind ofly prepare the method for anti-microbial polymer and the application of the anti-microbial polymer that obtains by the monomeric polymerization of aminofunctional.
The invention still further relates to and a kind ofly prepare the method for anti-microbial polymer and the application of the antimicrobial substrate that obtains by the graft polymerization of aminofunctional monomer on substrate.
Bacterium is in case settle down or spread at pipeline, container or surface of package, and that will be unusual brain people.Usually be, form slime layer earlier, just occur the sharp increase of microbial population thereupon, these microorganisms since then will be for a long time, constantly destroy the quality of water, beverage or food, even destroy product, harm consumer health.
The sphere of life that is placed on critical role in institute's handlebar health all must be accomplished away from bacterium.This relates to the textiles of direct contact bodies, particularly contacts genital area, and old man and patient care are used.At hospital ward, particularly grave illness is nursed and the Baby Care zone, and especially medical treatment gets involved regional furniture and instrument surface and also must avoid bacterium again, also have at the isolation ward that seriously infects case, and even in the lavatory.
Be used for equipment or furniture or textile surface are carried out the method for antimicrobial treatment at present,, all adopt chemical or its solution or mixture as sterilizing agent with suitable broad-spectrum antibacterial action no matter when needs or be used as preventive measures.The effect right and wrong of this type chemical agent are special, and they itself usually poisonous or with irritating, perhaps generate the degraded product that is harmful to health.Usually be in addition, the people is in case to certain material allergy, and from then on he just show and do not tolerate these materials.
Another kind prevents that the method that the surface of bacterium is spread from being that the material that will have anti-microbial effect is attached in the matrix.
Methacrylic acid tertiary butyl amino-ethyl ester is a ready-made available commercial in the methacrylated, especially is used in the copolyreaction as hydrophilic component.For example, EP 0 290 676 adopts various polyacrylic ester and polymethacrylate as matrix, is used for fixing the microbicidel quaternary ammonium compound.
In another technical field, US-A 4 532 269 discloses the terpolymer of a kind of butyl methacrylate, methacrylic acid tributyl tin and methacrylic acid tertiary butyl amino-ethyl ester.This polymkeric substance is used for various boats and ships as antimicrobial lacquer: hydrophilic methacrylic acid tertiary butyl amino-ethyl ester can impel this polymkeric substance gradually by erosion, thereby discharges this biocide of high toxicity methacrylic acid tributyl tin.
In these application scenarios, adopting the multipolymer of amino methyl acrylate preparation only is a kind of matrix or carrier substance, is intended to make the microbicide of adding to spread in carrier substance or moves.Sooner or later, in case no longer can reach " minimum inhibition concentration " (MIC) on its surface, the polymkeric substance of this type is just lost its effectiveness at once.
European patent application 0 862 858 and 0 862 859 open roads, methacrylic acid tertiary butyl amino-ethyl ester, a kind of methacrylic ester that has secondary amino group functional group, its all-and multipolymer possess the inherently microbicidal performance.For avoiding the undesirable resistance phenomenon of microorganisms, particularly in view of learning that from antibody research bacterium can develop immunity to drugs gradually, the system of exploitation also must continue following the novel composition direction with the effectiveness improved in the future.
Therefore, the objective of the invention is to research and develop a kind of novel polymer with anti-microbial effect.This polymkeric substance is randomly taked coating form, should prevent bacterium settling down and spread from the teeth outwards.
Surprisingly have now found that, by the polymerization of the aliphatic unsaturated monomer of monofunctional at least of uncle's amino group, generate a kind of polymkeric substance with long-acting microbicidel surface, it is not subjected to the erosion of solvent or physical stress and does not show migration yet.This make re-use other microbicides become unnecessary.
The invention provides a kind of method for preparing anti-microbial polymer, it is characterized in that, to by uncle's amino group at least the aliphatic unsaturated monomer of monofunctional carry out polymerization.
That the present invention uses, by uncle's amino group at least the aliphatic unsaturated monomer of monofunctional can have maximum 50 carbon atoms, preferred maximum 30 carbon atoms, the hydrocarbyl group of especially preferred maximum 22 carbon atoms.The substituting group of this amino group can be aliphatic series or vinyl hydrocarbyl group, methyl, ethyl, propyl group or acrylic groups groups such as (acrylic radicals) for example, perhaps cyclic hydrocarbon group group, the replacement of for example maximum 25 carbon atoms or unsubstituted phenyl or cyclohexyl groups.This amino group also can replace ketone group or aldehyde groups, for example group such as acryloyl or oxo.
For reaching enough rates of polymerization, the monomeric molar mass that the present invention uses should be less than 900, preferably less than 550g/mol.
A special embodiment of the present invention can adopt by aliphatic unsaturated monomer uncle's amino group monofunctional and that have following general formula,
R 1NR 2R 3R wherein 1Be branching, non-branching or cyclic, saturated or undersaturated hydrocarbyl group has maximum 50 carbon atoms, and it can be replaced by Sauerstoffatom, nitrogen-atoms or sulphur atom, and
R 2And R 3Can be identical or different, be branching, non-branching or cyclic, saturated or undersaturated hydrocarbyl group has maximum 25 carbon atoms, and it can be replaced by Sauerstoffatom, nitrogen-atoms or sulphur atom.
The suitable monomers structural unit is all aliphatic unsaturated monomers with at least one uncle's amido functional group, for example methacrylic acid 2-lignocaine ethyl ester, methacrylic acid 2-dimethylaminoethyl, methacryloyl 3-dimethylamino-propyl amine, vinylformic acid 2-lignocaine ethyl ester, vinylformic acid 2-dimethylaminoethyl, vinylformic acid 3-dimethylamino propyl ester or vinylformic acid 3-dimethylamino-2,2-dimethyl propyl ester.
The inventive method also can by by uncle's amino group at least the polymerization of monomer on substrate of monofunctional obtain.This will generate the physical adsorption coating of a kind of anti-microbial polymer on substrate.
Be fit to do the especially any polymer plastic of material of substrate, for example urethane, polymeric amide, polyester and polyethers, polyether block amide, polystyrene, polyvinyl chloride, polycarbonate, organopolysiloxane, polyolefine, polysulfones, polyisoprene, sovprene, polytetrafluoroethylene (PTFE) or corresponding multipolymer or blend, and also comprise natural or synthetic rubber, can have or be not with the radiation-sensitive group.The inventive method also can be used on body surface of metal, glass or timber top coat or other usefulness plastic-coated.
In another embodiment of the present invention, this anti-microbial polymer can by by uncle's amino group at least aliphatic unsaturated monomer graft polymerization on substrate of monofunctional prepare.Can produce covalent linkage between anti-microbial polymer and the substrate in the grafting on the substrate.Spendable substrate can be any polymeric material, plastics for example above-mentioned.
Before the graft polymerization reaction, the surface of substrate can be activated by variety of processes.Any standard method that is used for the activated polymer surface all can here be used, and for example substrate can activate with methods such as ultraviolet ray, Cement Composite Treated by Plasma, corona treatment, flame treating, ozonize, discharge or gamma-radiations before graft polymerization.Usefully, this surface is removed oil, fat or other pollutents by known way with solvent in advance.
Substrate can adopt ultraviolet activation, and its wavelength region is between 170～400nm, preferred 170～250nm.Suitable radiogenic example is Noblelight UV excimer (excimer) equipment (HERAEUS company (Hanau, a Germany)).Yet mercury vapor light also is suitable for the activation of substrate, as long as they launch the ray of the scope of mentioning above the significant proportion.Irradiation time is generally between 0.1s～20min, preferred 1s～10min.
Standard polymers also can adopt photosensitizers in addition with the activation that uv-radiation carries out.For this reason, photosensitizers paint substrate surface that will be such as benzophenone is carried out irradiation then.Equally, mercury vapor light also can here use, this moment irradiation time between 0.1s～20min, preferred 1s～10min.
According to the present invention, activation also can be passed through Cement Composite Treated by Plasma, uses RF (radio frequency) or microwave plasma (Hexagon, Technics Plasma company, 85551, Kirchheim, Germany) to carry out in air, nitrogen or argon gas atmosphere.Irradiation time is generally between 2s～30min, preferred 5s～10min.Under the situation of lab setup, the energy of supply is between 100～500W, preferred 200～300W.
Corona unit (SOFTAL, hamburger, Germany) also can be used for activation.Irradiation time, in this case generally between 1～10min, preferred 1～60s.
Utilize discharge, electron beam or gamma-radiation (for example from cobalt 60 source), also have the activation of ozonize etc. to allow to take the short irradiation time, generally between 0.1～60s.
Substrate surface also can reach activation by flame treating.Suitable device particularly has those of shielding (barrier) flame front, is easy to make or for example buy from ARCOTEC company (71297 M  nsheim, Germany).They can utilize hydro carbons or hydrogen to operate as combustion gases.Under any circumstance, all must avoid, and this is easy to by allowing the back of the body keep closely contacting being guaranteed with the refrigerative metallic surface towards the substrate side of flame treating one side because of the overheated substrate that damages.Therefore, the flame treating activation method is confined to situation relatively thinner, sheet substrate.Irradiation time is generally between 0.1s～1min, preferred 0.5～2s.The flame here is non-luminous without exception, and the distance between substrate surface and the flame front outside is between 0.2～5cm, preferred 0.5～2cm.
Through like this activatory substrate surface, be coated with by currently known methods, for example dip-coating, spraying or brush gone up by uncle's amino group aliphatic unsaturated monomer of monofunctional at least, randomly, applies with the solution form.Proved that useful solvent is Shui Heshui/alcohol mixture, however other solvents also can use, as long as they can dissolve these monomers and can wetting well substrate surface fully.The example of other solvents is ethanol, methyl alcohol, butanone, Anaesthetie Ether, dioxane, hexane, heptane, benzene, toluene, chloroform, methylene dichloride, tetrahydrofuran (THF) and acetonitrile.Monomer content is between 1～10wt%, and for example the solution of about 5wt% proves success in practice, just can provide after coating together usually and cover substrate surface, thickness can be greater than the adhering coating of 0.1 μ m.
Usefully, the monomeric graft polymerization on the paint activating surface can cause by the irradiation of the long-wave band of the short-wave band of the visible-range of electromagnetic radiation or ultraviolet light range.For example, wavelength is between 250～500nm, and the ray that preferred 290～320nm is sent by the burst of ultraviolel thing is very suitable.Mercury vapor light here also is fit to, as long as the radiation that they have significant proportion is positioned at above-mentioned scope.Irradiation time is generally between 10s～30min, preferred 2～15min.
This graft polymerization also can be implemented by european patent application 0 872 512 described methods, and this method is based on the graft polymerization reaction by swelling bonded monomer molecule and initiator molecule.
With the monomer of going up uncle's amino group, also can use other aliphatic unsaturated monomers except passing through functionalized in the methods of the invention.For example, used monomer mixture can comprise uncle's amino group for example vinylformic acid, methacrylic tert-butyl acrylate or methyl methacrylate, vinylbenzene, vinylchlorid, vinyl ether, acrylamide, vinyl cyanide, alkene (ethene, propylene, butylene and iso-butylene), allylic cpd, vinyl ketone, vinylacetic acid, vinyl acetate or vinyl ester of the aliphatic unsaturated monomer of monofunctional and acrylate or methyl acrylic ester at least.
Even if be not grafted to substrate surface, by the inventive method by uncle's amino group at least the anti-microbial polymer of the aliphatic unsaturated monomer preparation of monofunctional still show microbicidel or antimicrobial behavior.
If the inventive method directly is used in and does not carry out crosslinkedly on the substrate surface, then can adopt traditional radical initiator.The example of available initiator is azonitrile, alkyl peroxide, hydroperoxide, acyl peroxide, ketone peroxide, peroxy esters, peroxycarbonate (ester), peroxydisulfate, persulphate and any light trigger commonly used, for example phenyl methyl ketone, alpha-alcohol ketone, dimethyl ketal and benzophenone.This polyreaction also can adopt thermal initiation or, as noted above, by electromagnetic radiation, for example UV-light or gamma-radiation cause.
