Definitions
- Associative thickeners have been known thickeners for aqueous systems for many years. They come u. a. used in dispersion-based aqueous paints and varnishes, but also other aqueous systems, e.g. Cleaning agents, cosmetics, stripping agents, aqueous pigment pastes, car paints, industrial paints, printing inks, lubricating greases, plaster and wall paints, textile coatings, pharmaceutical preparations, crop protection formulations, filler dispersions, adhesives, detergents, wax dispersions, polishes, aids for tertiary oil production etc. rheologically adjusted.
- associative thickeners consist of a water-soluble hydrophilic main part, ie a water-soluble polymer chain, which mostly consists of polyethylene glycol or also of cellulose derivatives, acrylate chains, polyether chains or polyester chains, hydrophobic groups being attached to these polymer chains. Both parts are bound to each other by the most diverse types of covalent bonds.
- the linkage can be brought about, for example, by urethane bonds, ester bonds, ether bonds, urea bonds, carbonate bonds or amide bonds.
- the usual production of the associative thickener takes place by the fact that e.g. bifunctional alcohols (usually polyethylene glycol) react with bifunctional reactants (usually diisocyanates) in a polyaddition reaction and the addition reaction is ended by adding monofunctional reactants (e.g. monofunctional alcohols such as nonylphenol ethoxylate).
- bifunctional alcohols usually polyethylene glycol
- bifunctional reactants usually diisocyanates
- monofunctional reactants e.g. monofunctional alcohols such as nonylphenol ethoxylate
- the hydrophilic part remains dissolved in the application system in the aqueous phase.
- the hydrophobic groups attach themselves to hydrophobic surfaces, for example to the dispersed or emulsified organic binders in an aqueous coating, for example an emulsion paint, to the hydrophobic surfaces of fillers, pigments etc.
- a thickener polymer normally has two terminal ends (or several additional) hydrophobic parts, it can attach to several dispersion particles at the same time. These are linked together using the hydrophilic base chain. This creates a thickening effect, which is based on the association of the hydrophobic or the less water-soluble components and the construction of a three-dimensional one Network by means of van der Waals' interactions in the aqueous system. Hence the name associative thicker.
- hydrophobic components but not only with the hydrophobic components e.g. in one color, associate.
- the hydrophobic groups also associate with one another in the absence of a dispersion or other hydrophobic constituents and form e.g. Micelles. This also leads to a thickening. This thickening also takes place when only the thickening polymer alone is dissolved in water. Since the usual form of delivery of the polymer is an aqueous solution, it is understandable that excessive thickening is not desirable here. This makes processing or handling more difficult or limits the maximum concentration of the soluble thickener polymer in water to small percentages.
- the rheological effects of the thickener can be adjusted by selecting the hydrophobic end groups and / or adjusting the molecular weight, so that Newtonian associative thickeners (B) or also relatively pronounced structurally viscous associative thickeners (A) are produced.
- B Newtonian associative thickeners
- A structurally viscous associative thickeners
- the thinning effect is essentially due to the fact that these solvents themselves have a typical surfactant-like structure with a readily water-soluble end (alcohol / glycol) and a water-insoluble fraction (butyl group, etc.).
- the polarity by addition of the hydrophobic alkyl group to the hydrophobic group of the Assoziati werdickermoleküls "reversed” and the intensive interaction of the thickener molecules suppressed to each other or reduced. This. .Is to recognize in some cases also to the phenomenon that such liquid set Verdickerl ⁇ sache on addition of water first become thicker because the water-soluble solvents are diluted and their effect is reduced.
- VOC volatile organic content
- EP-A-0 614 950 describes one way of achieving this.
- Cyclodextrin is used here to suppress the solution viscosity of strongly structurally viscous associative thickeners in the delivery form without using solvents.
- the hydrophobic parts of the thickener are adsorbed in the hydrophobic parts of the cyclodexrin and prevented from mutual interactions.
- the disadvantage is that the cyclodextrins remain in the system, for example in color, after the associative thickener has been released.
- DE-A-36 30 319 describes polyurethane thickeners based on polypropylene / polyethylene glycol copolymers.
- the intended thickeners themselves should be liquids, not solids, which should therefore be pourable directly in water without a previous solution and therefore should not be dissolved in water as the delivery form, but should be approximately 100% liquid as an active ingredient.
- the thickening profile in the application system can be varied by combining several thickeners. However, the influence of the mixture of thickeners or the influence of propylene glycol-polyethylene glycol copolymer components in the thickener on the reduction of the solution viscosity of the thickener polymers in water was not mentioned or recognized.
- the object of the present invention was therefore to provide an associative thickener which can be dissolved in water in as high a concentration as possible without having too high a viscosity due to intermolecular association. Furthermore, the viscosity should be reduced without the use of solvents or condensers that can get into the atmosphere according to the VOC guideline (ie substances with a boiling point ⁇ 250 ° C) or emit emissions, e.g.
- VOC all organic substances which by total evaporation and subsequent gas chromatographic analysis to Retentionszei 'of the substance tetradecane t (boiling point: 252, 6 ° C) elute on a non-polar column.
- An associative thickener is said to be Newtonian (B) if its solution viscosity in 20% aqueous solution is less than 20,000 mPas (Brookfield viscometer, 20 rpm).
- an associative thickener In order to really be called an associative thickener and to ensure a clear differentiation from low molecular weight surfactants, this should at the same time cause a thickening in an emulsion system.
- 2.5 parts of the thickener are mixed into a mixture of 100 parts by weight of Acronal 290D (BASF, aqueous styrene-acrylate dispersion), 30 parts by weight of deionized water and 0.3 part by weight of defoamer ADDID 800 (Wacker, silicone defoamer for aqueous dispersions) stirred in homogeneously.
- Acronal 290D BASF, aqueous styrene-acrylate dispersion
- deionized water aqueous styrene-acrylate dispersion
- defoamer ADDID 800 Widecker, silicone defoamer for aqueous dispersions
- the viscosity at 10,000 sec "1 (Bohlin viscometer) after 4 hours of ripening is at least 50% higher than that of the blank sample.
- the molecular weight should be above 2500 g / mol, in particular above 1000 g / mol.
- An associative thickener is referred to here as shear thinning (A) if its solution viscosity in 20% aqueous solution is more than 100,000 mPas and the viscosity in the Acronal Test System at a shear rate of 1 sec "1 is more than 10,000 mPas (zu In this measurement, the structurally viscous associative thickener is mixed with 16% by weight butyl diglycol as a viscosity-reducing substance in order to be processable: 20% by weight thickener + 16% by weight butyl diglycol + 64% by weight water).
- the combination according to the invention of structurally viscous associative thickener (A) and Newtonian thickener (B) or / and plasticizer must have a low shear thickening at 1 sec "1 of at least 10,000 mPas in the acronal system " as a structurally viscous and 2.5 g of the thickener are homogeneously stirred into a mixture of 100 g of Acronal 290D (BASF), 30 g of deionized water and 0.3 g of defoamer ADDID 800 (Wacker) and measured after a rest period of 4 hours.
- BASF Acronal 290D
- deionized water deionized water
- ADDID 800 defoamer ADDID 800
- the invention further relates to a method for producing the above-defined association of thickener preparation, which is characterized in that
- A dissolves in water together with at least one Newtonian associative thickener (B);
- A dissolves in water together with at least one Newtonian associative thickener (B) and at least one plasticizer (C);
- (A) dissolves in water and adds at least one plasticizer (C);
- the invention furthermore relates to the use of the above-defined association of thickener preparation for adjusting the rheology of dispersion-bound aqueous paints and varnishes or other aqueous systems from the group of cleaning agents, cosmetics, stripping agents, aqueous pigment pastes, car paints, industrial paints, printing inks, greases, cleaning agents and Wall paints, textile coatings, pharmaceutical preparations, crop protection formulations, filler dispersions, adhesives, detergents, wax dispersions, polishes and auxiliaries for tertiary oil production.
- Aqueous solutions of a structurally viscous associative thickener (A) without the addition of solvents or plasticizers were prepared. provides. The concentration was gradually reduced from 20% by weight. A concentration was determined at which the solution viscosity was lower than 25,000 mPas. The amount of undissolved 100% Newtonian associative thickener (B) missing to 20% was now added to this solution. In the cases mentioned in the examples, the solution viscosity was in no way increased in the same ratio as Newtonian thickener was added. In most cases, the viscosity remained alone at or below the value of the viscosity of the pseudoplastic thickener, even though the total polymer content of associative thickeners was increased up to 5 times. Usually, the viscosity increases when thickeners are added to the individual thickener in the nonlinear additive range, in the relevant viscosity range of 2,000 to 25,000 mPas, almost exponentially.
- a Newtonian thickener (B) to a structurally viscous associative thickener leads to an increased thickening effect in the application system.
- the addition of the Newtonian thickener (B) only results in a subadditive increase in the solution viscosity or even a reduced viscosity compared to that of the pseudoplastic thickener portion alone.
- the pseudoplastic associative thickener (A) may be a special one Newtonian associative thickener (B) necessary to reduce the viscosity particularly well.
- the viscosity of an aqueous solution of e.g. pseudoplastic thickener (A) in water can also be suppressed by special plasticizers (C), e.g. by the copolymers described in more detail below.
- C plasticizers
- the alternating hydrophilic / hydrophobic co-poly can be produced by the co-condensation or co-polymerization of hydrophilic molecules or oligomers (D) with hydrophobic molecules (E).
- the hydrophobic portions (E) can be selected from XRX 2 , where R is a saturated or unsaturated aliphatic or cycloaliphatic radical having 2 to 12 carbon atoms, preferably having 3 to 6 carbon atoms, or an aromatic radical having 6 to 12 carbon atoms. Atoms, or a mixed aromatic / aliphatic radical having 6 to 17 carbon atoms and X and X 2 , which are the same or different and mean a function which can be reacted with Z and Z 2 , for example a carboxylic acid, carboxylic anhydride, carboxylic acid chloride , Ester, isocyanate, epoxy group or a halogen ion.
- Adipic acid, phthalic anhydride or dimethyl terephthalate are preferably used.
- the ratio of D / E is approximately 6: 5 to 5: 6, preferably approximately 3: 2 to 2: 3, in particular approximately 2: 1 to 1: 2.
- these materials also differ significantly from the usual materials used as plasticizers in accordance with VdL-RL 01 (Guideline for the Declaration of Ingredients in Architectural Coatings, Architectural Paints and Related Products, revised edition from April 2000), for example di-n-octyl phthalate , Di-n-butyl phthalate etc. are listed. In contrast to the plasticizers mentioned above, these materials do not contain any hydrophilic components.
- dibasic esters of adipic acid are proposed as film-forming aids or VOC-free solvents because of their high boiling point and low vapor pressure.
- Copolymers of diacids with polyethylene glycols are not mentioned.
- the use as a plasticizer (C) in associative thickener preparations accordingly also saves the addition of film auxiliaries or reduces their use.
- one or two terminating end groups with only one reactive function Z, Z 2 , X, or X 2 can be included.
- the statistical copolymers are preferred here over the block copolymers.
- the copolymer can be added to the thickener as a pure condenser or can be covalently incorporated into the thickener.
- the pure admixture of polypropylene glycol / polyethylene glycol copolymers also lowers the aqueous solution viscosity of the thickener.
- the molar proportion of propylene glycol and / or butylene glycol in the polyethylene glycol is ideally between 10 and 60 mol%.
- Pure polypropylene glycols are too poorly water-soluble and show less condensing action, as are pure polybutylene glycols.
- relatively short chain propylene or butylene glycols can be used, are water soluble and have a plasticizing effect.
- These are preferably oligomeric propylene or butylene glycols with up to 10 monomer units.
- the propylene glycols preferably have a molecular weight of up to about 700 g / mol, the butylene glycols of up to about 500 g / mol.
- Block copolymers such as PEG-PPG-PEG (polyethylene glycol-polypropylene glycol-polyethylene glycol) are usually less effective. Polyethylene glycol polymers are readily soluble, but their effect is insufficient.
- Hexanediol can also be used. This has a boiling point of over 253 ° C and is therefore not a VOC; it also has the additional advantage that it is solid at room temperature and therefore does not increase the stickiness and dirt absorption of the paint film.
- hydrophobically modified, ethoxylated aminoplasts i.e. the pure 100% solid polymers (without water and butyl diglycol) of the following commercial products from Süd-Chemie AG are used.
- the solid polymers can be obtained from the commercial products by evaporating off the solvents; however, the polymers can also be used directly after preparation, before they are dissolved:
- Hydrophobically modified ethoxylated aminoplasts i.e. the pure solid polymers (without water) of the following commercial products from Süd-Chemie AG are used:

- the liquefiers (C) were produced as follows:
- 101 g of tetraethylene glycol (0.5 mol) are dried for 2 hours at 100 ° C and 20 hPa. Then 90 g of dimethyl adipate (0.5 mol) and then 1 g of 30% methanolic solution of NaOMe are added. The methanol formed is removed in vacuo at 100 ° C. with stirring until the bubbles have stopped. Then the vacuum is broken and 0.3 g of glacial acetic acid (equimolecular to the NaOMe used) is stirred in.
- the X, X 2 ester on the hydrophobic part (E)
- the reaction is carried out under toluenesulphonic acid catalysis at about 120-220 ° C under vacuum and ended as soon as most of the theoretically calculated water has been removed in vacuo and is deposited in the cold trap.

- Table V shows an example of the use of a statistical hydrophilic-hydrophobic copolymer as part of the associative polymer thickener (example 67) in comparison to otherwise comparable thickeners which, as usual, contain the hydrophilic homopolymer polyethylene glycol (examples 68 to 71). If the viscosity in water is acceptable, the thickening effect in the test binder is roughly comparable to that of the corresponding comparison substances.
- Table VI lists examples in which combinations of pseudoplastic (A) and Newtonian thickeners (B) are additionally mixed with the plasticizers (C). This can further reduce the viscosity in water or increase the solids content of the pseudoplastic thickener.
