TM3300 composition successfully and effectively gives brown paper with antimicrobial property.
[0063] similarly, the total phenol content of described antimicrobial compositions (for example, alkyl, styreneization or the combination of the two) is between about 10 weight % and about 60 weight % of whole compositions.Preferred embodiment use about 20 weight % between about 50 weight % alkyl phenol and about 1 weight % to the styrenated phenol between about 10 weight %.
[0064] in a kind of papermaking process that exemplifies, determines that the combination of alkyl phenol and styrenated phenol is best for the ad hoc approach effect.Particularly, preferred total phenol content is between about 25 weight % and the about 50 weight % in that embodiment.The optimization of ad hoc approach causes alkyl phenol to approach about 44 weight % and styrenated phenol approaches about 5 weight %.
[0065] being expected at will be between about 0 weight % and about 20 weight % for the amount of the required defoamer of successful implementation of the present invention in the great majority application.
[0066] remainder of described antimicrobial compositions comprises water.The water yield that exists in claimed composition will be between about 5 weight % and about 30 weight %, more preferably between about 10 weight % and about 20 weight % in preferred embodiments.In addition, the accurate amount of water will depend on that application-specific and those skilled in the art can carry out necessary adjustment.
[0067] the present invention also comprises the method for making described antimicrobial compositions.
[0068] broadly, described method comprises the following step: phenol is mixed with the quaternary ammonium antimicrobial, if necessary with the phenol and the quaternary ammonium antimicrobial heating (combination of some phenol/quaternary salt reagent (quaternaryagent) can not need heating) that mix, and some water of fusion.
[0069] in preferred embodiments, when heating exists with described phenol (for example, TRITON
TMX-207) with described quaternary ammonium antimicrobial (for example, ONYXIDE
TM) mix.Application of heat is because the quaternary ammonium antimicrobial at room temperature is a solid in many cases.It should be noted that not that mixture with phenol and antimicrobial is heated to exists unacceptable any degree of volatilization.
[0070] if ONYXIDE
TMBe antimicrobial, recommend the mixing temperature between about 65 ℃ and about 75 ℃ so.At the described ONYXIDE of this temperature
TMBe molten in the phenol and form liquid.
[0071] if desired or expectation, defoamer and antifreezing agent be those can adding in this point of discussing in front for example.
[0072] in case, can remove described heating with described antimicrobial and phenol mixing.When the mixture cool to room temperature, along with stirring adds entry.
[0073] relative quantity of the antimicrobial that in described method, uses, phenol and water with discuss about described composition those are identical.Similarly, the relative quantity of defoamer, antifreezing agent and additional antimicrobial is if use, with identical about those of the discussion of described composition.
Antimicrobial compositions #3
[0074] the nonmetal antimicrobial that means of terminology used here is different from quaternary ammonium compound, and it does not contain or uses metal ion (for example, Ag, Cu).
[0075] in another embodiment, described antimicrobial compositions comprises the micro emulsion of quaternary ammonium antimicrobial and two kinds of dissimilar nonmetal antimicrobials.Described micro emulsion can be with two kinds of forms.A kind of is the water-containing microemulsion-like liquid that fully is applicable to Aquo System.Another kind is the non-aqueous microemulsions that fully is applicable to non-water or type of organic solvent system.In the scope of heat guard, requiring described water-containing microemulsion-like liquid will be the form of more frequent use.
[0076] turn to the more particular embodiment of this antimicrobial compositions now, a kind of embodiment is moisture antimicrobial compositions, and it can give antimicrobial property brown paper and many different products.In its most basic form, this embodiment of the present invention comprises water-containing microemulsion-like liquid.Described micro emulsion comprises quaternary ammonium antimicrobial, phenol, the first nonmetal antimicrobial, the second nonmetal antimicrobial, He Shui.What is interesting is that described composition needn't contain the volatile alcohol (for example, ethanol) through being used to form quaternary ammonium antimicrobial emulsion.Each of these compositions, and other are preferably and optional ingredients, will discuss in more detail below.
[0077] the quaternary ammonium antimicrobial that uses in this composition is included in those that list in the embodiment of antimicrobial compositions of front.
[0078] in particularly preferred embodiments, described quaternary ammonium antimicrobial comprises for example N-alkyl dimethyl benzyl ammonium saccharin of dimethyl benzyl ammonium compounds.N-alkyl dimethyl benzyl ammonium saccharin is that Illinois merchant sells by Stepan Chemical Company of Northfield, and commodity are called ONYXCIDE
TM3300.The ONYXIDE of this particular form
TMBe approximately 95% activity and at room temperature be solid, but liquid will be formed at elevated temperatures.It on the color is being Melon yellow look and insoluble in water.
[0079] phenol that uses in enforcement of the present invention can contain the alkyl phenol with at least one alkyl, and described alkyl is selected from the group of being made up of C7 alkyl, C8 alkyl, C9 alkyl, C10 alkyl and C11 alkyl.
[0080] in the most preferred embodiment, described alkyl phenol comprises the alkyl phenol with C9 alkyl.
[0081] alkyl phenol that is suitable for being used in the enforcement of claimed invention is sold by many source merchants.It is with commodity TRITON by name by Dow Chemical Company that particularly preferred merchant sells alkyl phenol
TMX-207 sells.
[0082] alternatively, the phenol that uses in enforcement of the present invention can comprise styrenated phenol.Two examples that are applicable to the styrenated phenol that uses with the present invention are CHROMASIST WEZ and STANDAPOL HS.The both is that Ohio merchant sells by Cognis Corporation of Cincinnati.The both is discerned by CAS#3217120.Technical data sheet points out that the between main distinction is the level of ethoxylation.
[0083] the different phenol that can adopt in the enforcement of this embodiment of the present invention are the examples of adaptability of the present invention and the possible selection that must carry out in the invention process of those skilled in the art.It will be appreciated by those skilled in the art that a kind of phenol can play better effect in a kind of specific paper or heat guard manufacture method.For the of the present invention meticulous adjustment that is fit to ad hoc approach be expection and should not limit the scope of the invention by any way.Those skilled in the art need not be too much experiment can carry out less and necessary adjustment the present invention is adapted to their ad hoc approach.
[0084] the nonmetal antimicrobial that uses in this embodiment of the present invention is preferably selected from the antimicrobial of pyrroles family.Generally speaking, pyroles comprises the compound that a big class is characterized by five-membered ring, and described ring contains a nitrogen-atoms and at least one other non-carbon atom (for example, nitrogen, oxygen and sulphur).Some pyroles performance antimicrobial (that is, antimycotic) character.Triazole is the subclass of pyroles, and it is usually as antimicrobial.
[0085] the two or more antimicrobial triazoles of knowing are propiconazole and Tebuconazole.The chemical name of propiconazole (CAS No.50207-90-1) is 1[[2-(2, the 4-dichlorophenyl)-4-propyl group-1,3-dioxolanes-2-yl] methyl]-1H-1,2, the 4-triazole.The chemical name of Tebuconazole (CAS No.107534-96-3) is α-[2-(4-chlorphenyl) ethyl]-α-(1, the 1-dimethyl ethyl)-1H-1,2, and 4-triazole-1-ethanol.
[0086] Tebuconazole is sold from many source merchants.The Tebuconazole of a special preferred form is sold from Bayer Corporation merchant, and trade name is PREVENTOL
TMA8.Similarly, propiconazole is available from many sources.The propiconazole of a special preferred form obtains from JanssenPharmaceutica, and trade name is WOCOSEN
TMTECHNICAL.
[0087] in particularly preferred embodiments, the described first and second nonmetal antimicrobials are propiconazole and Tebuconazole.Any reagent can be " first " or " second "; Concrete title is unimportant.Yet, to discuss for convenient, it will be second agent non-metallic that Tebuconazole will generally be referred to do described first agent non-metallic and propiconazole.
[0088] if desired, a spot of dihydroxylic alcohols may reside in according in the composition of the present invention.Dihydroxylic alcohols can increase the stability of emulsion and provide other benefit for example to postpone foam.Preferred dihydroxylic alcohols comprises alkyl diol, and polyethylene glycol, polypropylene glycol and dipropylene glycol are preferred.
[0089] other main component of the antimicrobial compositions of water composition requirement protection.
[0090] can contain other additive according to antimicrobial compositions of the present invention.Two kinds of such additives are defoamer and antifreezing agent.
[0091] some phenols that use in enforcement of the present invention can be to be easy to foamyly, depend on specific application.Therefore, expect that many industrial implementation schemes of the present invention will contain defoamer.
[0092] for example, this composition can be used to handle brown paper.Such paper is used for forming outer surface on heat guard.A kind of method of handling this type paper is that described antimicrobial compositions is joined described water tank, and described water tank is the device for the paper conversion end, after described paper experience is based on the drying of heat a certain amount of water is turned back to described paper.
[0093] described water tank normally stirs, and reason is that paper passes moving continuously of it.This stirring can be at the fashionable generation foam that adds of described claimed antimicrobial compositions.Usually, the existence of foam partly is harmful to the water tank of paper conversion.Therefore when the present invention is used in the water tank treatment paper, defoamer is joined according to composition of the present invention.
[0094] described paper also can utilize spray bars to handle.Foam increase in spray bars can be harmful to method, so also defoamer can be used there.
[0095] preferred defoamer is the copolymer of the ethoxylation of polyethylene glycol.In some cases, the commercial formulation of phenols can contain some defoamers.For example, TRITON
TMX-207 contains a spot of polyethylene glycol.Therefore, if TRITON
TMX-207 is a source of phenol, can not need other defoamer so.
[0096] similarly, antifreezing agent can be joined according to composition of the present invention.They are used for preventing that described composition from freezing or become too sticking in the transportation of cold weather.As a rule, dihydroxylic alcohols will serve as the function of antifreezing agent.Preferred antifreezing agent is a dipropylene glycol.
[0097] one of benefit of this composition is that it provides platform new and that improve to be used to utilize the anti-microbial properties of multiple pyroles and particularly Tebuconazole and propiconazole.Present for many years those skilled in the art have known the general synergy between Tebuconazole and the propiconazole.In other words, by Tebuconazole and the propiconazole that utilizes combining form,, can realize bigger anti-microbial effect for the antimicrobial of specified rate.
[0098] Tebuconazole and propiconazole are also well-known is their hydrophobicity and the difficulty of using in aqueous environment.Their opposings form aqueous emulsion and can be forced to the degree of the aqueous emulsion that becomes some types to them, described emulsion is tending towards fragile and unstable easily (for example, active material forms crystal and is settled out or they form different phases with water in water).
[0099] yet, composition according to the present invention provides stable quaternary ammonium antimicrobial and the aqueous emulsion of pyroles, particularly Tebuconazole and propiconazole.This composition can be diluted into about the pyrroles of the combination of pyrroles's (for example, propiconazole of the Tebuconazole of 100 ppm and 100 ppm) of the combination of 0.02 (weight) % or simmer down to about 50 (weight) %.This feature provides huge flexibility can how using in the described composition.
