Definitions
- the present invention describes fluorine-free cationic polyurethane dispersions, their preparation and use on fabrics, fabrics, loops, knits, fibers, nonwovens and knits to significantly increase water repellency and detergency together with a fluorine-free wax dispersion.
- Textile materials are used for a variety of applications. However, their absorbency and permeability to water are undesirable in many applications. For outdoor textiles such as rainwear and tarpaulins or permanent outdoor textiles such as awnings and geotextiles, these properties are disadvantageous. Since the sole choice of textile material can not find a technically adequate and economically acceptable solution to the problem, these textiles are treated with water-repellent agents. For a long time, perfluorinated acrylate systems and the equipment based on them dominated the market. Such fluorine-containing surface treatments not only allow excellent water repellency, but also bring along oil and dirt repellent effects. Despite these technical properties, the perfluorinated coatings are now on withdrawal, since they are considered to be persistent and bioaccumulative (M. Santen, U. Kailee, Chemistry for Any Weather, Greenpeace eV, 2012, p. 5).
- anionic dispersions Most of the polyurethane dispersions on the market are anionic. These anionic dispersions carry, for example, carboxylate or sulfonate groups which are firmly polymerized into the polymer backbone and thus contribute to significantly worsening both the hydrophobicity of such dispersions on the textile and the washing permanence.
- cationic dispersions which have been dispersed with the aid of a volatile acid, this problem does not occur because the acid evaporates under normal drying conditions and the amino groups thus no longer exist in their protonated form.
- the term of the volatile acid is defined according to the invention in that they have a boiling point of up to 180 ° C, preferably up to 150 ° C at atmospheric pressure.
- WO 2012 058534 A with respect to, the benefits of Jeffcat ® DPA compared to N-methyl diethanolamine (NMDEA) dispersion stability of cationic polyurethane dispersions out.
- diol component polytetrahydrofurans, polypropylene glycols and a polyester diol based on hexanediol, neopentyl glycol and adipic acid were used.
- This application describes applications of such dispersions in ink jet printing, glass fiber and paper finishing and in electroplating. Applications on textiles were not mentioned.
- Nor are cationic polyurethane dispersions described which were prepared from highly hydrophobic polyester diols.
- US 6140412 A describes the use of cationic polyurethane dispersions for impregnating inkjet printer paper. According to the knowledge of the inventors at the time of application to textiles, the diol components described in this document can not be used to realize the required hydrophobizing effects. In addition, exclusively amines are used in the synthesis of the polymer whose tertiary amino groups are incorporated linearly into the polymer chain. As a result, coarse-particle dispersions are obtained with hydrophobic diols as starting material, which are not suitable for textile application. Examples with laterally arranged tertiary amino groups are not described.
- cationic polyurethane dispersions described in FR 293477 A are all hydrophilic for cosmetic applications.
- Hydrophobic polyester diols for the synthesis of polyurethane dispersions prepared from dicarboxylic acids and diols have long been known to the skilled person.
- EP 0740674 Bl describes, inter alia, the preparation of hydrophobic polyester diols based on dimeric fatty acids with butylethylpropanediol.
- anionic polyurethane dispersions prepared therefrom with the field of application in the lubricating oil sector are described in this document. Due to the anionic charge is to assume a poor wash permanence, making such products for the hydrophobization of textiles are less suitable.
- waxes are frequently applied with polymer dispersions.
- the use of fatty acrylate-based copolymers together with wax emulsions has been known for some time (C. Tomasino, Chemistry & Technology of Fabric Preparation & Finishing, pp. 158-171, web call dated 30.04.2013, http://infohouse.p2ric.org /ref/06/05815.pdf).
- Solvent-based polyacrylates are described in DE 1238215 A1, but due to their adverse process and environmental influences, such systems can not be used in the textile industry.
- EP 2 411 575 B1 mentions the use of terpolymers based on alkyl acrylates, chlorine-containing vinyl compounds and styrene derivatives in combination with waxes as aqueous dispersions.
- styrene-containing polymers is unsuitable due to the yellowing tendency of these compounds and also halogen-containing substances are undesirable for environmental reasons in the textile industry.
- Vinyl esters of the cooking acids as a constituent of copolymer wax dispersions were mentioned in EP 1 424 433 B1, but are unfavorable due to the high price.
- DE 10211549 B9 describes the preparation of reaction products of fatty acids or stearyl isocyanate with alcohols or amines. These are reacted in a second reaction step in solvent with isocyanate groups and then transferred in conjunction with waxes in dispersions. These dispersions are used as a hydrophobic surface finish. By using solvents that must be removed again, the process is complex and costly.
- the use of polyurethane coatings is described in DE 10 2009 014699 AI. However, the hydrophobicity described by the authors does not meet the requirements at the time of application, especially since only contact angles were checked and no washing tests were carried out. This is understandable in that comparatively large amounts of emulsifiers are required and they must first be removed.
- H-siloxanes for the hydrophobization of textiles is known for example from DE 1231663 AI.
- wrinkle-free equipment can be achieved at the same time (cf. US Pat. No. 3,032,442).
- these mentioned systems have the serious disadvantage that elemental hydrogen can be released during textile finishing, which represents a considerable process risk.
- they require anhydrous, flammable solvents and toxicologically questionable catalysts and are therefore not applicable in the textile industry.
- EP 2 152 957 B1 also uses the described component from DE 10211549 B9 in conjunction with alkyl-modified organosiloxanes. Inter alia, by the use of isopropyl acetate as a solvent, which must be removed again, the process is complicated and therefore costly.
- JP 2006-124866 A1 reports on the use of a non-functionalized polydimethylsiloxane in compounds with crosslinking agents for the hydrophobicization of textile materials.
- the crosslinker is preferably based on a carbodiimide.
- EP 1 108 765 Bl describes carboxy-functional silicones as water repellents for furs and leather, optionally together with paraffins.
- the disadvantage is that they - applied to textile materials - would lose their water-repellent effect at the latest after a household wash with a commercial alkaline detergent, since the necessary acid groups are then deprotonated.
- the authors also describe a dispersion process in which the silicone is first reacted with a base, then dispersed in a mixture of water and an organic solvent, from which finally this solvent has to be removed by distillation.
- EP 1 035 200 A2 describes a wiper cloth finished with one or more hydrophobic components with the aim of producing a water-repellent film on an automobile surface treated therewith, the hydrophobic finish being transferred from the textile to the wiped surface.
- the authors also state that the amount of emulsifier must not be too high for such a system, since otherwise the hydrophobing effect is lost. Accordingly, the smallest possible amounts of surface-active substances are advantageous.
- compositions based on technical stearyl stearate (C18 / C18 with C16 fractions), which achieve good hydrophobing in combination with silicone waxes and optionally further waxes.
- the example compositions give only by addition of other substances, such as the formaldehyde-containing melamine resin Freepel ® 1200 (Example 1) or in the remaining examples by the addition of a blocked isocyanate sufficient hydrophobization.
- Formaldehyde is classified as carcinogenic at the time of filing in Europe; blocked Isocyanates are also toxicologically questionable.
- a typical representative of a blocking agent namely butanone oxime, is classified as cmr.
- fluorine-free cationic polyurethane dispersions are known as an additive in mixtures with fluorine-free wax and / or paraffin dispersions for impregnation and / or coating of fabrics, wherein the polyurethane is prepared by reaction of one or more hydrophobic diols and one or more Hydroxyl phenomenon- containing tertiary amino compounds, one or more diisocyanates, with or without addition of solvent and conversion of the resulting polymeric reaction product in water with the aid of volatile acid and suitable emulsifying agents.
- An essential component of the technical teaching here is the use of blocking agents, which usually have cmr properties and are therefore of toxicological concern. Since such blocking agents must be eliminated at high temperatures, use from an energetic point of view is also disadvantageous.
- cationic, fluorine-free wax and / or paraffin-containing dispersions can be markedly improved in their water-repellent effect when the cationic, fluorine-free polyurethane dispersions are added to them. This is all the more astonishing since no water-repellent effects can be achieved with the cationic polyurethane dispersions according to the invention alone. In addition, the cationic polyurethane dispersions significantly improve the washing permanence of the water-repellent effects.
- a first embodiment of the present invention relates to a fluorine-free cationic CMR-free polyurethane dispersion as additive in mixtures with fluorine-free wax and / or paraffin dispersions for impregnation and / or coating of fabrics, wherein the polyurethane is prepared by reaction of one or more hydrophobic polymeric diol with an average molecular mass of 1000 to 5000 g / mol and one or more hydroxyl-containing tertiary amino compound, one or more diisocyanates, with or without addition of solvent and conversion of the resulting polymeric reaction product in water with the aid of volatile acid and suitable emulsifying aids, in particular, if the Dispersion is free of pbt substances and / or free of blocking agents, in particular cmr blocking agents.
- the invention describes the chemistry of the fluorine-free cationic polyurethane dispersions and their preparation, which in combination with cationic, fluorine-free wax dispersions contribute to a significant improvement of the water-repellent effects while improving the washing permanence and thereby manages without the use of blocking agents.
- the cationic polyurethane dispersions are prepared by reacting one or more hydrophobic polymeric diols or one or more hydrophobic polyester diols with one or more Hydroxyl-containing tertiary amino compounds, one or more diisocyanates, with or without addition of solvent and the dispersion of the resulting polymeric reaction product in water with the aid of volatile acid and suitable emulsifiers.
- the dispersion in water can be carried out either by the "transfer process” known per se or by the use of solvents according to the "solvent process” known per se.
- chain extension may be achieved by reaction of still free isocyanate groups with amines, either in water or in solvent.
- diamines are used which carry two isocyanate-reactive amino groups, or three-dimensional crosslinking takes place by means of amines which contain at least three isocyanate-reactive amino groups.
- a chain extension also occurs when no amine is added since existing free isocyanate groups can hydrolyze to amino groups and then react with another free isocyanate group.
- amines which carry only one isocyanate-reactive, amino group can be brought as a chain terminator to the reaction.
- Suitable hydrophobic polymeric diols are commercially available hydrophobic silicone carbinols and polycarbonate diols. Furthermore, polycaprolactones and polytetrahydrofurans can also be used as starting material. Polyethylene glycols, polypropylene glycols and EO / PO block polymers, however, are unsuitable.
- the hydrophobic polyester diols used particularly preferably for this invention have themselves been synthesized by an acid esterification of one or more dicarboxylic acids with one or more diols and consist of monomeric units either on the diol and / or on the dicarboxylic acid side have at least 9 carbon atoms and thus a relatively low density of ester groups.

- Suitable diols are aliphatic, cycloaliphatic and aromatic diols having a total of at least 4 carbon atoms. Particular preference is given to butanediol, pentanediol, hexanediol, octanediol, nonanediol, decanediol, undecanediol, dodecanediol, tridecanediol, tetradecanediol, hexadecanediol, dimeric fatty alcohols, cyclohexanedimethanol, butylethypropanediol, 1,2-benzenedimethanol, 1,3-benzenedimethanol and 1,4-benzenedimethanol.
- the hydrophobic polyester diols prepared by the prior art by means of acid esterification from the abovementioned dicarboxylic acids and diols have a calculated (average) molecular mass of ⁇ 7000 g / mol, preferably from 1000 to 5000 g / mol.
- the isocyanates used are of the general formula X (NCO) 2 , where X is 4 to 12 carbon atoms in the case of an aliphatic hydrocarbon radical, 6 to 25 carbon atoms in the case of a cycloaliphatic hydrocarbon radical or 6 to 15 in the case of an aromatic hydrocarbon radical Carbon atoms can be.
- diisocyanates examples include tetramethylene diisocyanate, hexamethylene diisocyanate, dodecane methylene diisocyanate, 1,4-diisocyanato-cyclohexane, 3-isocyanatomethyl-3,3,5-tri-methylcyclohexylisocyanate (isophorone diisocyanate), 4,4 'diisocyanatocyclohexylmethane, 4,4' diisocyanato-3,3 '-dimethyl-dicyclohexylmethane, 4,4' diisocyanatocyclohexyl propane - (2,2), 1,4 diisocyanatobenzene, 2,4 or 2,6 diisocyanatotoluene or mixtures of these isomers, 4,4'-2,4 ', or 2 , 2 'Diisocyanatodiphenylmethan or mixtures of these isomers, 4,4' diisocyanate,
- catalysts have been selected according to the prior art as well as their toxicological properties. Preference is given to catalysts based on tertiary amines such as, for example, 1,4-diazabicyclo [2.2.2] octane (DABCO) and diazabicycloundecene (DBU) and also compounds of transition metals. Mentioned here are bismuth compounds such as Bismuth neodecanoate, manganese or zinc compounds such as zinc ethylhexanoate.
- DABCO 1,4-diazabicyclo [2.2.2] octane
- DBU diazabicycloundecene
- transition metals Mentioned here are bismuth compounds such as Bismuth neodecanoate, manganese or zinc compounds such as zinc ethylhexanoate.
- Amine alcohols having a tertiary amino group are incorporated during the synthesis of the polyester polyurethane in order to achieve a good dispersion quality with the smallest possible particle size when transferred to water.
- What is needed are amines having at least one tertiary amino group, which is converted by protonation with a preferably volatile acid into an ionic group and decisively contributes to a good dispersion quality.
- Preference is given to aliphatic hydroxy compounds such as N, N-dimethylethanolamine, ⁇ , ⁇ , ⁇ '-trimethyl-N'-
- Trimethylaminoethylethanolamine (Jeffcat ® Z 110).
- aliphatic N-alkyl dialkanolamines such as N-methyldiethanolamine, N-methyldipropanolamine, or ethoxylated N-methyldiethanolamine.
- acids for protonation of the amino groups are preferably volatile organic and / or inorganic acids are used, since the hydrophobicity and permanence can be significantly increased by the evaporation of the acid in conventional drying processes.
- formic acid, propionic acid or hydrochloric acid are preferred, and acetic acid is very particularly preferred for the purposes of the invention.
- Chain extenders are used according to the state of the art according to diamines. These are preferably aliphatic and / or cycloaliphatic diamino compounds.

- cycloaliphatic diamino compounds are examples of cycloaliphatic diamino compounds.
- Chain extension then occurs via partial hydrolysis of free isocyanate groups to amino groups.
- Suitable solvents are only aprotic solvents which can not undergo reactions with isocyanate. They are preferably ketones, esters and ethers. Examples of ketones are acetone, methyl ethyl ketone, methyl isobutyl ketone and cyclohexanone. Examples of esters are isopropyl acetate, Butylactetat, methoxypropyl (Dowanol ® PMA) and dipropylene glycol methyl ether acetate (Dowanol ® DPMA). One example of ether is dipropylene (propylene glycol ® DME, Proglyde ® DMM).
- Suitable dispersing agents must not have any significant surface activity and thus no good wetting effect. Preference is therefore given to longer-chain, hydrogenated fatty alcohols higher degree of ethoxylation, such as stearyl alcohol x 25 EO (Lutensol® AT 25) or ethoxylated fatty acid ester such as hydrogenated castor oil 60 EO x (Simulsol 1294 ®) or C30 wax alcohol x 40 EO (Unithox ® 480)
