Description

POLYURETHANE ORGANOPOLYSILOXANES WITH CARBODIIMIDE GROUPS

The invention relates to polyurethane and / or polyorganosiloxane copolymer compounds and their salts, the carbodiimide structural units of the formula [I]

- N = C = N—; [I] included.

The invention further relates to processes for their preparation, precursors for their preparation and reactive compositions which contain such precursors and their use for fiber treatment or fiber finishing, including hair and wool, and for permanent finishing, treatment, impregnation of textiles and Leather or synthetic leather as well as other fibrous materials as well as fabrics and paper.

Aqueous and solvent-containing polyurethane and / or polyurea-polyorganosiloxane copolymer compounds have long been known extensively for the treatment of surfaces (WO 2008/060681).

The preparation of polysiloxane-carbodiimide copolymers has also been known for a long time and has been described in detail. (DE 26 02 413A1) It is also known that polysiloxanes and / or polyurethane-polyorganosiloxane copolymers containing amino groups are suitable as textile plasticizers (WO 2006/002910).

It is also known that the introduction of alkylene oxide units into such polymers can improve the hydrophilicity.

Furthermore, for example in WO 2008/060681 it was proposed to improve the substantivity of these products by introducing quaternary ammonium compounds into alkylene oxide-modified polysiloxanes and / or polyurethane-polyorganosiloxane copolymers.

However, this proposal does not provide a satisfactory solution to the problem that the systems mentioned for fiber treatment and for the permanent finishing, treatment, impregnation of textiles, paper, wool and leather or synthetic leather are exposed to repetitively aggressive environments during alkaline environments, oxidative conditions and during washing and thereby lose their effectiveness or even completely lapse.

One possibility of maintaining the effect of a plasticizer is dealt with in EP 0 933 399 A. In this case, aminosiloxanes are covalently crosslinked via Michael addition using polyfunctional acrylic acid derivatives which, however, do not bind covalently to the substrate, but only crosslink with themselves and thereby show a worse permanence.

A crosslinkable composition based on aminosilicon is also proposed by EP 0 563 961 A. The crosslinking takes place via anhydrides through an acylation reaction. However, the products described in this document no longer meet today's requirements in terms of permanence.

Quaternary aminosiloxanes terminated with silanols are described in DE 32 36 466 A, the crosslinking being carried out by condensation of the alkoxysilanes also contained and additional crosslinkable trialkoxysilanes with the respective alkanol being split off. The so obtained Products are characterized by a good soft feel, but their durability over several household washes no longer meets today's requirements.

The invention DE 10 2013 224 140 A deals with a further approach to the permanent initial finishing of a textile, in which a hydrophobic finishing agent is covalently bound to the textile fabric by a blocked isocyanate with elimination of the low molecular weight blocking agent. The disadvantage here, however, is the toxicologically questionable blocking agent, which is released during the crosslinking process and remains in part on the goods.

WO 2004/050472, on the other hand, describes a solution without such a questionable condensation process in which reactive amino or ammonium polysiloxane compounds are described, which can be covalently bound to the textile substrate via an isocyanate dimer, but have the disadvantage that they do not result in any aqueous, storage-stable systems can be produced since the isocyanate dimer hydrolyzes in an aqueous environment with elimination of carbon dioxide and thus loses its mode of action.

None of these treated products can therefore increase the permanence of hydrophilic plasticizers for fiber treatment and for permanent finishing, treatment, impregnation of textiles, paper, wool and leather or synthetic leather to a satisfactory result.

It is therefore an object of the invention to prepare permanent and thus significantly more efficient and toxicologically harmless and thus PBT and CMR-free amino and or quaternary amino functional preparations for fiber treatment or fiber finishing, including hair and wool, and for permanent finishing, treatment, impregnation of Textiles and leather or synthetic leather and other fibrous materials as well as fabrics and paper, based on polyurethane and / or polyurea-polyorganosiloxane copolymer compounds, which according to the present invention are generally represented by the formula leave described, where Ri of the structure

obeyed and which also contain at least one carbodiimide function of the formula [I], in particular as a wash-permanent plasticizer for textile finishing, the characteristic softness of such compounds also being obtained by recurring washing processes using anionic, cationic, amphoteric or nonionic Detergents are hardly affected.

It is known that carbodiimides of the formula [I] can be incorporated into the structures [II] and [III] according to the invention by, when building up the polyurethane and / or polyurea-polyorganosiloxane copolymer compounds, diisocyanates of the general formula [ IV] used. (DE 197 33 044 A)

Compounds with an average molecular weight of 250 to 100,000 / mol, but in particular with a molecular weight of 500 to 4,000 g / mol, are particularly preferred.

A, w-primary or secondary amino- or hydroxyalkyl- or hydroxypolyetheralkyl-functionalized polyorganosiloxanes having the structure [VII] are very particularly suitable for the purpose according to the invention. in which s = 2 to 500, but more preferably 5 to 200, D and D 'is a primary or secondary hydroxyl- or aminoalkyl- or hydroxypolyether-terminated organic radical of up to 200 carbon atoms, which leads to a chemical addition reaction is capable of isocyanates and can be prepared, for example, by a hydrosilylation reaction according to the prior art, D and D 'can also be the same or different and R ^{x is} a straight-chain, branched, cyclic, saturated, unsaturated, aromatic, substituted or unsubstituted ter Is hydrocarbon residue with up to 20 hydrocarbon atoms, which can also carry amino, or quaternary ammonium compounds or hydroxyalkyl or hydroxypolyetheralkyl groups, whereby a comb-like structure can be obtained. In addition, especially monofunctional polyorganosiloxanes of structure [VIII] and [IX]

for the construction of suitable polyurethane and / or polyurea-polyorganosiloxane copolymer compounds according to the invention, the carbodiimide Functions contain suitably, where R ^x and D are as described above and s'> / = 1, but in particular 1.

In order to achieve formulations according to the invention of the polyurethane and / or polyurea-polyorganosiloxane copolymer compounds in water, isocyanate-terminated precursors of the structure -V- with Zerewinowow-active monomers of the formula can be used are brought to reaction which have one or more hydrophilic groups -J- or can be converted into hydrophilic groups by suitable means.

The hydrophilic or hydrophilizable groups are anionic or preferably groups of cationic or nonionic nature.

The nonionic hydrophilic groups used are hydrophilic polyalkylene oxides with a functionality of 1 to 3, in particular, however, polyethylene glycol diols or monols with 5 to 100, but preferably 10 to 50, repeating sequences, the proportion of which is preferably 0 to 15% by weight, but especially 2 to 10 wt .-% based on the weight of the monomers of the composition according to the invention.

Suitable ionic hydrophilic groups are, for example, anionic groups, in particular carboxylate, sulfonate or phosphonate groups, preferably for fiber treatment or fiber finishing, including hair and wool, and for permanent finishing, treatment, impregnation of textiles and leather or synthetic leather and other fibrous materials and fabrics and Paper, on the other hand, cationic groups, especially ammonium groups, protonated tertiary amino groups or quaternary ammonium groups, which can be converted into your salts by simple neutralization, hydrolysis or quaternization reactions. Monomers with carboxyl, sulfonic acid groups or phosphoric acid groups which can be converted to their anions by bases are usually aliphatic, aromatic or cycloaliphatic in nature and also carry at least one Zerewitinow-active group of the general functionality (VI), preference being given to dihydroxysulfonic acids, dihydroxyphosphonic acids such as 2,3-dihydroxypropanephosphonic acid or dihydroxycarboxylic acids such as dimethylolbutanoic acid, but especially dimethylolpropionic acid (bis-MPA) is used. The conversion of the carboxyl, sulfonic acid groups or phosphoric acid groups into their salts preferably takes place with a cation of an alkali metal or an ammonium ion as the cation. Amines, in particular triethylamine, dimethylethanolamine, trimethylamine or ammonia, are particularly preferred.

Alternatively, it is also possible to use monomers with amino groups reactive towards isocyanates, such as amino acids, in particular lysine, or alanine, but mainly compounds of the structure [XI]

NH ₂ - K— NH— K'— A _[XI]

In which K and K 'independently of one another represent a straight - chain, branched, cyclic, saturated, unsaturated or aromatic hydrocarbon radical with up to 20 carbon atoms, preferably a Ci to C5 alkyl unit, in particular ethylene and A is COOH or S0 ₃ H, or their alkali metal salts or ammonium salts, Na being particularly preferred as a cation and very particularly preferably N- (2-aminoethyl) -2-aminoethanesulfonic acid.

Compounds with tertiary amino groups, for example tris (hydroxyalkyl) amines, N, N'-bis (hydroxyalkyl) alkylamines, N-hydroxyalkyl dialkylamines, tris (aminoalkyl), are particularly suitable as potentially cationic monomers according to the invention. amines, N, N'-bis (aminoalkyl) alkylamines, N-aminoalkyl-dialkylamines or their quaternary ammonium compounds obtained by suitable quaternization reactions, their Al- alkyl radicals straight-chain, branched, cyclic, saturated, unsaturated or aromatic hydrocarbon radicals with up to 20 carbon atoms, which may also contain several groups of -0-, -C (O) -, -NH-, tertiary amines or quaternary ammonium compounds. Aliphatic hydroxyl compounds such as N, N-dimethylethanolamine, N, N, N'-trimethyl-N'- are preferred.

Hydroxyethylbisaminoethylether (Jeffcat® ZF-10), N, N-Bis (3-dimethylaminopropyl) -N-isopropanolamine (Jeffcat® ZR50), 2- (2-

Dimethylaminoethoxy) ethanol (Jeffcat® ZR-70), N, N, N'-

Trimethylaminoethylethanolamine (Jeffcat® Z 110). N-methyldiethanolamine, N-methyldipropanolamine or ethoxylated N-methyldiethanolamine are particularly preferred. Very particularly preferred are compounds which, in addition to 2 hydroxyl groups, also contain at least one tertiary amino group which is not built into the polymer backbone but always remains on the sides. Examples include N- (3-dimethylaminopropyl) -N, N-diethanolamine), N- (3-dimethylaminopropyl) -N, N-diisopropanolamine

(Jeffcat® DPA), or N, N bis (2-hydroxyethyl) isonicotinamide.

These tertiary amines are converted into their corresponding salts with acids, preferably volatile organic and / or inorganic acids being used, since the evaporation of the acid at customary drying temperatures can significantly increase the hydrophobicity and permanence. Preference is therefore, for example, formic acid, propionic acid, hydrochloric acid, phosphoric acid, lactic acid, citric acid and acetic acid is very particularly preferred for the purposes of the invention.

So-called chain extenders -U- according to the prior art are also common in the aqueous medium. These are preferably polyfunctional amines with a molecular weight between 32 g / mol and 1000 g / mol. Examples include hydrazine, ethylenediamine, diaminopropane, diaminobutane, hexamethylene diamine, piperazine, isophoronediamine (IPDA), or higher-functional amines such as diethylenetriamine or triethylenetetramine. However, monofunctional amines which are used as chain terminators, for example diethanolamine and / or which simultaneously carry a hydrophilic group, are particularly preferred according to the invention, eg 3-dimethylaminopropylamine. Furthermore, amino-functional polyethers with 2 to 100 repeating sequences of linear, mono- or bifunctional homopolymers or randomly distributed polymers or block copolymers of butylene oxide, styrene oxide and in particular ethylene oxide, tetrahydrofuran, propylene oxide or mixtures of these can also be used here, since they increase the elasticity of the polymer obtained therefrom and, if ethylene oxide is present as a monomer, can contribute to the water dispersibility of the preparation. These polyetheramines are available, for example, as Jeffamine ®. Furthermore, the addition of chain extenders can also be dispensed with entirely. The chain extension then takes place via the partial hydrolysis of remaining isocyanate groups to amino groups.

Aprotic solvents which cannot react with isocyanates are used as solvents. 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, butyl acetate, methoxypropyl acetate (Dowanol® PMA) and dipropylene glycol methyl ether acetate (Dowanol® DPMA) and dibasic esters. An example of ether is dipropylene glycol dimethyl ether (Propylene Glycol® DME, Proglyde® DMM), or end-capped polyethylene glycols, such as Polyglycol DME 500.

To accelerate the reaction of the isocyanates with Zerewitinow-active compounds, the customary catalysts according to the prior art, such as dibutyltin dilaurate (DBTL), tin-II-octoate, 1,4-diazabicyclo- (2,2,2) - octane (DABCO), diazabicycloundecene (DBU) and compounds of transition metals, especially bismuth compounds such as Bismuth neodecanoate or zinc compounds such as zinc ethyl hexanoate.

The compositions according to the invention can be in the form of a colloidal two-phase system, dispersion aids of anionic, cationic or nonionic nature being used to prepare these dispersions, emulsions or microemulsions, where as nonionic emulsifiers, in particular alkyl polyglycol ethers, alkylaryl polyglycol ethers which contain 8 to 30 carbon atoms and 5 to 80 ethylene and / or propylene oxide units, block copolymers of ethylene oxide and propylene oxide, preferably with 5 to 40 EO or PO units, natural products and their derivatives from lecithin, sapione, cellulose, cellulose alkyl ether and carboxyalkyl celluloses as well as linear or branched (poly) dimethylsiloxanes with alkoxy groups of up to 50 EO or PO groups and 3 to 20 silicone units can be used. Furthermore, alkyl sulfates, alkyl ether sulfates, alkyl sulfonates, alkylarylsulfonates with a chain length of 8 to 22 carbon atoms in the hydrophobic radical and 1 to 40 ethylene or propylene oxide units, alkali or ammonium salts of carboxylic acids with 10 to 22 carbon atoms in the lipophilic radical and the Salts of partial phosphoric acid esters with 10 to 22 carbon atoms in the alkyl or alkaryl radical and with up to 40 EO units. The salts of primary, secondary and tertiary fatty amines and quaternary ammonium compounds having 10 to 22 carbon atoms are preferably used as cationic dispersing agents, with salts of those of formic acid, acetic acid, lactic acid or other organic and inorganic acids being conceivable, as well as in the case of the quaternary ones Ammonium compounds, their halides, sulfates, phosphates or acetates.
