Description

[Technical Field]

[0001] The present invention relates to polysiloxanes having zwitterionic groups, their preparation, compositions containing such polysiloxanes, and the use of these polysiloxanes or compositions to treat substrates. [Background technology]

[0002] Polysiloxanes are used in a variety of ways to finish textile materials, and because of their flexible structure and ease of functionalization, they can be customized for many different applications.

[0003] Amino-modified polysiloxanes have long been used as softening agents. They are usually applied to textiles as liquid preparations in the form of aqueous emulsions. With the addition of emulsifiers, amino-modified polysiloxanes form stable emulsions in water at acidic pH values.

[0004] However, the described formulations have a number of drawbacks, such as low stability under alkaline conditions, high sensitivity to salts and anions, and poor resistance to shear stress during application in modern finishing machines. Another drawback is the pronounced susceptibility of treated substrates to thermal yellowing, especially at drying temperatures above 120°C.

[0005] However, many textile pretreatment processes require the use of high pH values ​​in aqueous treatment baths. For example, pretreatment, bleaching, and dyeing of cellulose substrates routinely require the use of large amounts of alkali. If such process steps are not adequately neutralized and carefully washed, alkaline components can be carried over to subsequent treatment baths containing softeners, which can lead to destabilization of emulsions of amino-functional polysiloxanes. Emulsion destabilization under alkaline conditions is due to deprotonation of the amino functional groups of the polysiloxane. Without a cationic charge on the polysiloxane, the microemulsion will coagulate. The resulting coagulum can deposit unevenly on the textile being treated, causing staining of the textile.

[0006] Emulsions of polysiloxanes bearing quaternary ammonium groups can at least partially overcome the aforementioned drawbacks. The preparation of diquaternary polysiloxanes is described, for example, in U.S. Patent No. 5,623,999. They are synthesized by reacting a polysiloxane having terminal epoxide groups with a tertiary amine in a ratio such that each epoxide group corresponds to at least one tertiary amino group. The reaction is carried out at elevated temperatures in the presence of an acid in an amount equivalent to the nitrogen atoms to be quaternized. Due to this special preparation method, the resulting diquaternary polysiloxanes have quaternary ammonium groups located only at the terminals. Compounds prepared in this manner are recommended for use in hair treatment products and cosmetics.

[0007] Ammonium-modified polysiloxanes and polyether-modified polysiloxanes are described in Patent Document 2. These polysiloxanes are prepared from epoxy-functional polysiloxanes by reacting the epoxy-functional polysiloxanes with amines and alkyl alcohol alkoxylates. This is followed by quaternization with an alkylating agent. These polysiloxanes are used to finish textile substrates and are characterized by high resistance to thermal yellowing. Due to the terminal polyether and ammonium groups, they also have good pH stability.

[0008] However, the above-mentioned advantages of polysiloxanes containing quaternary ammonium groups are offset under practical conditions by the drawback that they often exhibit poor resistance to phenolic yellowing, to anionic textile auxiliaries, to the addition of salts, and to the shear effects in the presence of anions and with the addition of salts, especially in jet processes.

[0009] In a jet dyer, the finish is subjected to strong dynamic loads due to high shear forces, which can destabilize the treatment and lead to the formation of undesirable stains, as mentioned above.

[0010] In the softening of dyed or optically brightened fabrics in a jet dyeing machine, where the fabric has already been dyed or optically brightened, it is important that, on the one hand, there is no undesired separation from the destabilized softening emulsion, and, on the other hand, the respective dyeing or optically brightening is not impaired. [Prior art documents] [Patent documents]

[0011] [Patent Document 1] U.S. Patent No. 4,891,166 [Patent Document 2] German patent no. 102005056864 Summary of the Invention [Problem to be solved by the invention]

[0012] The problem is therefore to provide an improved polysiloxane for soft-hand finishes that meets these requirements and overcomes the drawbacks of the prior art. In particular, polysiloxanes that have high emulsion stability against anions, salts, pH changes, and strong shear forces, as well as combinations of these influences, and that are resistant to thermal and phenolic yellowing, should be provided. [Means for solving the problem]

The polysiloxanes according to the invention are not only suitable as softening agents, but can also be added to paints, glazes, lacquers, and car care products, for example, to improve their wetting, spreading, and / or leveling properties.

[0080] In a preferred embodiment, the composition according to the invention further comprises (iv) at least one additive, for example a diluent, such as polyethylene glycol having a molecular weight of 200 g / mol to 10,000 g / mol, preferably 400 g / mol to 6,000 g / mol, and / or glycerol, and / or urea, and / or at least one acid, in particular an organic acid such as acetic acid or lactic acid. The stability of the composition can be further improved by protonating any tertiary amino groups present in the polysiloxane.

[0081] In a particularly preferred embodiment, the composition according to the invention comprises (i) at least one polysiloxane according to the invention, (ii) a solvent, in particular water, and (iii) at least one emulsifier; Includes.

[0082] In this case, the composition according to the invention is preferably an emulsion, in particular an oil-in-water emulsion, or a treatment liquid, in particular an aqueous treatment liquid. The preparation of the emulsion according to the invention is carried out according to methods known to those skilled in the art, for example at temperatures between 15°C and 70°C.

[0083] The emulsion preferably contains 5 to 60% by weight, and particularly preferably 10 to 40% by weight, of component (i) based on the total weight of the emulsion. The treatment liquid preferably contains 0.005 to 3.0% by weight, and particularly preferably 0.01 to 1.2% by weight of component (i) based on the total weight of the emulsion.

[0084] In a particularly preferred embodiment, the composition according to the invention comprises (i) at least one polysiloxane according to the invention, (ii) a solvent, in particular water, and (iv) at least one additive, in particular an acid.

[0085] In a particularly preferred embodiment, the composition according to the invention comprises (i) at least one polysiloxane according to the invention, (ii) a solvent, in particular water, (iii) at least one emulsifier, and (iv) at least one additive, in particular an acid.

[0086] In a further preferred embodiment, the composition according to the invention comprises (i) at least one polysiloxane according to the invention, (ii) a solvent, in particular water, (iii) at least one emulsifier, and (iv) at least one additive, in particular an acid, and / or at least one softening agent, preferably an organically modified polysiloxane.

[0087] Suitable softening agents are, for example, polysiloxanes having amino groups, quaternary ammonium groups (quat), polyether groups, and / or (poly)urethane groups, and combinations thereof.

[0088] The organomodified polysiloxane is different from the polysiloxane according to Formula A.

[0089] Surprisingly, the compositions, especially emulsions, are particularly stable to shear stress and anions, especially in the presence of salts, and are resistant to phenolic yellowing.This facilitates the uniform treatment of substrates, especially the uniform finishing of textiles with these compositions.High process stability is a great advantage, especially when finishing using jet processing, because, in addition to the other factors mentioned above, high shear stress often acts, which can have a strong destabilizing effect on emulsions.

[0090] Without being bound by any theory, it is assumed that the zwitterionic groups in the polysiloxanes according to the invention contribute significantly to stabilization against these effects.

[0091] A further aspect of the present invention relates to the use of a polysiloxane according to the invention or a composition according to the invention in the treatment of substrates or as an additive in paints, glazes, varnishes and / or car care formulations. Preferred substrates for use according to the present invention are textiles, leather, metal, glass, wood or plastics.

[0092] In a preferred embodiment, the composition according to the invention is an additive for paints, glazes, varnishes and / or car care formulations comprising at least one polysiloxane (i) according to the invention and an organic solvent, in which case the composition preferably comprises 0.1% to 99.9% by weight, particularly preferably 0.5% to 99% by weight, and most preferably 10% to 90% by weight of component (i), based on the total weight of the composition.

[0093] In car care and coating compositions, component (i) may be present from 0.1% to 5% by weight based on the total weight of the composition.

[0094] The use according to the invention for finishing textile substrates is preferred. In particular, the textile substrates can be woven, knitted, nonwoven, fiber, and / or leather products, or mixtures thereof. According to the invention, the textile substrates can comprise natural fibers, in particular cotton and / or wool, and / or synthetic fibers, in particular viscose, polyester, polyamide, and / or polyacrylonitrile.

[0095] The emulsions or aqueous dilutions of these emulsions, also known as treatment solutions, are preferably used to finish textile substrates.

[0096] Surprisingly, it has been shown that the polysiloxanes according to the invention allow for uniform application under all conditions when treating substrates. Due to their high emulsion stability, they allow for uniform finishing of the substrate even under conditions that would otherwise have a destabilizing effect on the emulsion, such as high pH values, the presence of salts, the presence of anions, and / or strong shear forces.

[0097] In a preferred embodiment, the polysiloxanes or compositions according to the present invention can be used to improve the softness and handle of textile substrates. Surprisingly, finishing with the polysiloxanes according to the present invention has been shown to produce excellent softness and handle in treated textiles without compromising hydrophilicity. Fabrics treated in this manner have also been shown to be stable to thermal and / or phenolic yellowing.

[0098] The use of the present invention to finish dyed or optically brightened articles offers unique advantages: the finishing can even be carried out in the same jet dyeing machine in which the fabric was dyed or optically brightened. Surprisingly, it has been shown that finishing with the polysiloxane or composition according to the present invention does not impair the coloring or optically brightening effect, respectively, while at the same time significantly improving the softness and handle of the fabric.

[0099] In a further preferred embodiment, the polysiloxanes or compositions according to the present invention can be used to improve the wetting, spreading, leveling, and / or foaming behavior of paints, glazes, varnishes, and / or car care formulations. The use of polysiloxanes according to the present invention can reduce the surface tension of these formulations, depending on their application, thereby allowing the formulation to flow more uniformly and / or wet the substrate better, thereby avoiding cratering. Additionally, the presence of polysiloxanes according to the present invention in the formulations can improve the surface smoothness of the treated material. In car care products, the compositions, among other things, prevent so-called sheeting, i.e., the spreading of (rain) water on the treated surface. This accelerates the breakdown of the water film, allowing the water to run off more easily and accelerating drying. Furthermore, the polysiloxanes according to the present invention can have a degassing and / or defoaming effect.

[0100] A further aspect of the present invention relates to a substrate, in particular a textile substrate, treated with the polysiloxane according to the invention. Preferably, the substrate according to the invention comprises 0.04 to 2.4% by weight, particularly preferably 0.08 to 1.2% by weight, of the polysiloxane according to the invention, based on the total weight of the textile substrate. The substrate is preferably one of the substrates described above.

[0101] In a particularly preferred embodiment, the substrate is a textile substrate as described above.

[0102] In an alternative embodiment, the substrate is a metal substrate.

[0103] Another aspect of the present invention is a method for producing a semiconductor device comprising: (i) providing a substrate; (ii) applying a polysiloxane according to the invention or a composition according to the invention to a substrate; (iii) optionally treating the substrate obtained after step (ii) at an elevated temperature; The present invention relates to a process for treating a substrate, comprising:

[0104] The substrate in steps (i) to (iii) is preferably one of the substrates described above. In a particularly preferred embodiment, the substrate is a textile substrate as described above.

[0105] The application of the polysiloxane according to the invention or the composition according to the invention to the substrate in step (ii) can preferably be carried out by padding, spraying, brushing, dipping, patting and / or exhaust processes, for example, a textile substrate can be finished with the polysiloxane according to the invention or the composition according to the invention by exhaustion in a jet.

[0106] In a preferred embodiment, in step (iii) of the process according to the invention, water is removed, preferably at a temperature between 110° C. and 150° C., optionally under reduced pressure. DETAILED DESCRIPTION OF THE INVENTION

[0114] Example 5 (according to the invention): 7.04 g (74.5 mmol) of chloroacetic acid was dissolved in 5.00 g of HO and 10.0 g of butyl glycol. To this solution, 5.96 g (74.5 mmol) of 50% sodium hydroxide solution was added with stirring. After stirring for 15 minutes, 100 g of Intermediate A from Example 2 (corresponding to 149 mmol of tertiary nitrogen) was added, and the mixture was stirred at 75° C. for 4 hours to yield a slightly yellowish organopolysiloxane.

[0116] Example 7 (according to the invention): 500 g of an α,ω-dihydrogen polydimethylsiloxane having 0.035 wt % Si-bonded hydrogen (corresponding to 176 mmol of Si—H) and an average chain length of 75 was added over 60 minutes to a solution of 26.3 mg of Karstedt catalyst in 26.1 g (229 mmol) of allyl glycidyl ether, previously adjusted to 135° C. After removal of excess allyl glycidyl ether by distillation, 33.0 g (176 mmol) of bis[3-(dimethylamino)propyl]amine was added slowly at 135° C. The catalyst was then cooled to 50° C. Then, the mixture was cooled to 50°C, and 896 mg of 1,4-diazabicyclo[2.2.2]octane and 38.1 g (172 mmol) of isophorone diisocyanate were added. The mixture was stirred at 70°C until the NCO band in the IR spectrum disappeared, yielding a yellowish organopolysiloxane (Polysiloxane Adduct C).

[0117] 75.1 g of polysiloxane adduct C (equivalent to 46.6 mmol of tertiary nitrogen) was heated with 5.00 g of HO, 10.0 g of butyl glycol, 2.64 g (28.0 mmol) of chloroacetic acid, and 2.24 g (28.0 mmol) of 50% sodium hydroxide solution to 75° C.

[0118] Emulsion example General emulsification instructions: The specified amount of emulsifier was added to the organopolysiloxane to be emulsified at room temperature and stirred with a wall-mounted anchor-type stirrer until a uniform mixture was obtained. H2O was added in portions to the mixture and stirred until all of the water was absorbed.

[0119] [Table 1]

[0120] Application Examples Soft grip evaluation Slices of non-optically brightened cotton terrycloth were finished in a Mathis Labomat at a bath ratio of 1:10 for 20 minutes at 40°C using an aqueous treatment solution containing 20 g / l of the emulsion prepared according to the examples and adjusted to pH 5 with 60% acetic acid. Excess treatment solution was then squeezed out using a laboratory padder at 3 bar, followed by drying at 140°C for 2 minutes. The circulation speed was 45 rpm.

[0121] The gripping properties of the emulsion-treated test fabrics were then evaluated. This is subject to subjective criteria that vary from person to person, and evaluations by at least five testers are required to obtain meaningful results. Results were analyzed using statistical methods, with a rating of 1 representing the softest, most comfortable grip in the test series and a rating of 3 representing the hardest, least soft, and most uncomfortable grip.

[0122] [Table 2]

[0123] hydrophilic The hydrophilicity of cotton terry fabrics finished for soft handling evaluation was evaluated according to the TEGEWA drop test method (Melliand Textilberichte 68 (1987), 581-583).

[0124] [Table 3]

[0125] Anion Stability 100 ml of the emulsion to be tested was prepared in each of two beakers at a concentration of 40 g / L in water. To the first beaker was added 100 ml of a 4 g / L solution of VEROLAN™ NEW (an organic dispersant containing polyacrylate and alkyl phosphonate, anionic active). To the second beaker was added 100 ml of a 12 g / L solution of RUCO-BLANC™ AMA (a whitening agent, stilbene derivative, anionic active). The treatment solution was adjusted to pH 5 with 60% acetic acid.

[0126] After a standing time of 6 hours, the evaluation was carried out according to the following grading system: 1. The processing solution is transparent 2 The treatment solution is cloudy or "slightly cloudy" 3 The treatment solution is flocculated or has a precipitate that can be reconstituted by stirring (does not flocculate again within 1 minute). 4 Formation of large flakes or precipitate that can no longer be stirred 5 Oily deposits on the surface of the treatment liquid or beaker

[0127] If the grade is no worse than "3", the exam is considered passed.

[0128] [Table 4]

[0129] heat yellowing Sections of bleached, non-fluorescently whitened cotton modal knit fabric were impregnated in a lab foulard with an aqueous treatment solution containing 20 g / l of the emulsion prepared according to the examples and 0.5 g / l of 60% acetic acid at 80% wet absorption, dried for 2 minutes at 120° C., and then heat-set for 2 minutes at 170° C. The whiteness of the samples was then measured with a whiteness meter "texflash 2000" from "datacolor international" (Switzerland) according to Ganz (Applied Optics 15 (1976) 9, 2039-2058).

[0130] [Table 5]

[0131] The preparations according to the invention do not cause yellowing of the textile substrates, and the whiteness of the substrates treated with the preparations according to the invention corresponds to the whiteness of the untreated textiles.

[0132] Phenol yellowing Sections of bleached, non-fluorescently whitened cotton Modal knitted fabric were impregnated in a laboratory foulard with an aqueous treatment solution containing 40 g / l of the emulsion prepared according to the examples and 0.5 g / l of 60% acetic acid at a wet absorption of 80% and then dried for 2 minutes at 120° C. Yellowing was then assessed using the sandwich test (DIN EN ISO 105-X18).

[0133] Each test sample and control tissue is individually placed between two horizontally stacked glass plates, between the folded test paper, and the stack of plates, test paper, test sample, and control tissue is then airtightly wrapped and incubated in a heating cabinet at 50°C for 16 hours.

[0134] After opening the packaging, any possible color changes are immediately assessed using a gray scale on a scale of 1 to 5 according to ISO 105-A01.

[0135] The higher the value on the grey scale, the less yellowing the textile.

[0136] [Table 6]

[0137] Jet Stability In a beaker, 400 mL of a treatment solution containing 4 g / L sodium sulfate and 5 g / L of the emulsion to be tested in water was adjusted to pH 4.5 with 60% acetic acid. The aqueous treatment solution was then heated to 40° C. and stirred at this temperature for 20 minutes at 2000 revolutions per minute using a pitched blade stirrer. At the end of this time, the stirrer was turned off and the solution was evaluated for separation after a one-hour settling period. This test is intended to simulate the mechanical forces of the jet process in the presence of textile auxiliaries remaining on the textile from the previous finishing step.
