Definitions
- the present application relates to aqueous dispersions which contain fluorine-containing and fluorine-free poly (meth) acrylates and the use of such dispersions for the hydrophobic finishing of fibers and textile fabrics.
- the present invention thus relates to aqueous dispersions which comprise at least: a) a copolymer of compounds of the formula (I) (I) in which R 1 is a branched or unbranched alkyl radical having 8 to 22 carbon atoms and R 2 is a hydrogen atom or an alkyl radical having 1 to 4 carbon atoms, with
- Formula (Ia) stands, and c) emulsifiers with the proviso that the weight ratio between the copolymers to a) to the copolymers to b) is 10: 1 to 1:10.
- the perfluorinated compounds of the formula (II) are generally prepared on the basis of tetrafluoroethane, which is polymerized and iodinated and, in the course of a Grignard reaction, is reacted with ethylene oxide to give a perfluorinated alcohol. In a final reaction step, this is reacted with acrylic acid or methacrylic acid to give the desired perfluorinated acrylates or methacrylate esters.
- the index n is a number from 6 to 10.
- the compounds of the formula (I) are likewise known esters of acrylic or methacrylic acid with fatty alcohols, the fatty alcohols having to have 8 to 22 carbon atoms.
- the monomers of the formulas (I) and (II) are reacted independently of one another with the acrylic or methacrylic acid esters of the formula (Ia), as a rule by copolymerization in an aqueous medium to give copolymers, emulsifiers c) being used, and then the two components a) and b), which for production reasons already contain the emulsifiers, are mixed to give the dispersions according to the invention.
- Emulsion polymerization is a special method of polymerization in which water-insoluble monomers are emulsified in water with the aid of emulsifiers and polymerized using water-soluble initiators (e.g. potassium persulfate; redox initiators).
- water-soluble initiators e.g. potassium persulfate; redox initiators.
- Particularly preferred monomers of the formula (Ia) are selected from the group consisting of the group consisting of methyl, ethyl, n-propyl, i-propyl and / or butyl esters of acrylic or methacrylic acid.
- the compounds of the formula (Ia) can be used independently of one another for the preparation of the polymer dispersions a) and b).
- the proportion of monomers of the formulas (I) or (II) in relation to the comonomers (Ia) is at least 50% by weight, preferably at least 70% by weight. % is. It is also possible to polymerize only monomers of the formulas (I) or (II). However, the proportion of comonomers of the formula (Ia) in the polymerization is preferably at least 5% by weight.
- the weight ratio between components a) and b) is in the range from 10: 1 to 1:10, but preferably in the range from 5: 1 to 1: 3.
- the ranges 3: 1 to 1: 1 are particularly preferred.
- the dispersions according to the invention necessarily contain emulsifiers c) for stabilization.
- the emulsifiers are preferably selected from the nonionic and / or cationic emulsifiers.
- the emulsifiers are particularly preferably the cationic emulsifiers, which are compounds which contain a positive charge in the form of a quaternized ammonium group or a charge-neutral amine group which change to the ionically protonated form when the overall system is acidified. Examples of such cationic compounds can be found in WO 88/00991 on pages 2 and 3. But also other quaternized compounds known to the person skilled in the art, in particular so-called esterquats, i.e. H. quaternized alkylammonium compounds which carry at least one ester group in the alkyl group are suitable for stabilizing the dispersions according to the invention.
- the aqueous dispersions according to the present teaching according to the invention contain components a) and b) in total in amounts of 0.1 to 50% by weight, preferably in amounts of 1 to 35% by weight, in each case based on the total weight of the aqueous dispersion.
- the emulsifiers c) are present in amounts of 0.1 to 10% by weight, preferably 0.5 to 5% by weight, in each case based on the total weight of the dispersion. It may be advantageous to use water-miscible organic solvents in addition to components a) and b) and the emulsifiers c).
- polyols with 2 to 6 carbon atoms and 2 to 6 hydroxyl groups, the alkyl ethers or Partial alkyl ethers of these polyols or the fully or partially alkoxylated derivatives of the polyols or around acetone.
- the dispersions according to the invention are produced by first mixing an aqueous, cationically or nonionically stabilized dispersion a) with an aqueous, cationically or nonionically stabilized dispersion b). The mixture contained in this way can then be applied to textiles and fibers in a manner which is suitable and known per se. Suitable textile materials are cotton as well as polyester or polyamide fibers as well as blended fabrics.
- the aqueous dispersions according to the invention are applied to the fibers or the fabric by means of common application technology, for example a padder roller.
- the active ingredient concentration is preferably between 1 to 5 g per liter, based on the liquor.
- Another object of the present invention relates to the use of aqueous dispersions, as described above, for the hydrophobic finishing of fibers and textile fabrics.
