Definitions
- the present invention relates to an aqueous effect pigment paste comprising at least one effect pigment (a) and at least one polymer (b) which can be prepared by successive free-radical emulsion polymerization of three monomer mixtures (A), (B) and (C) of olefinically unsaturated monomers in water, an aqueous basecoat which can be prepared by admixing the effect pigment paste to at least one aqueous binder-containing component suitable for the preparation of the basecoat, a process for producing a multicoat system using this basecoat, and a use of the polymerizate (b) for dispersing effect pigments within an aqueous base effect pigment paste.
- Pigment pastes and polymers used therein are known in the art. Through the use of pigment pastes, the technically complex process of pigment dispersion is substantially facilitated in the paint industry, since it ensures, for example, dust-free processing of pigments during the formulation of paints.
- the pigments are optimally wetted by incorporation into the paste and very well dispersed, so that an improved distribution state is achieved in the resulting paint. This results in improved application-technological properties of the paint and the coating produced therefrom, for example, a particularly homogeneous color or color distribution of the paint.
- Effect pigment-containing pigment pastes are prepared separately for the same reasons prior to incorporation into a coating such as a water-based paint as an intermediate, since a direct incorporation of these pigments in the paint causes the above problems, especially with regard to insufficient dispersion and wetting the pigments in the case of direct addition.
- precisely matched polymers must be used as paste binders to obtain an optimally conditioned paste. Without an individual adaptation and accurate selection of the polymer, the respective pigment can usually not be optimally dispersed, so that the application-technological properties of the paint ultimately resulting therefrom are also not optimal.
- the corresponding paste binder does not always correspond to the main binder of the coating composition, so that a further binder component is introduced into the coating agent by the paste.
- the manufacturing process of the coating composition becomes more complex.
- other coating components must in turn also be matched to this polymer.
- there is less scope for the use of further additives and / or binder components in the coating since in particular the proportion of the primary binder of primary importance can be lowered too much.
- a polymer which corresponds to the main binder in the resulting coating composition, must usually compromise on the choice of the main binder and thus the quality of the resulting coating composition and the received with multi-layer coating produced, but this is undesirable.
- pigment pastes which are aqueous or have the lowest possible content of organic solvents.
- DE 103 50 719 A1 discloses effect pigment pastes which contain, in addition to an effect pigment, a (meth) acrylate copolymer present in a primary dispersion.
- these polymers described in DE 103 50 719 A1 have comparatively high glass transition temperatures, which may possibly lead to insufficient adhesion properties.
- aqueous pigment pastes which, in addition to a pigment such as an effect pigment, contain a polyurethane-based copolymer which can be prepared by copolymerization of a mixture of olefinically unsaturated monomers in the presence of a polyurethane.
- the pigment pastes disclosed in WO 2015/090811 A1 do not always lead to the desired pinhole robustness after incorporation into a coating agent such as a water-based paint.
- effect pigment pastes containing polyester and comparatively high amounts of organic solvents, such as butyl glycol, are known in the prior art.
- organic solvents such as butyl glycol
- a disadvantage of these effect pigment pastes is their low storage stability and their comparatively high solvent and polyester content.
- solvent-based effect pigment pastes are described, for example, in WO 92/15405 A1.
- EP 1 534 792 B1 discloses aqueous metal pigment pastes which are free of binders, including friction resins, but which, inter alia, must necessarily contain a non-associative (meth) acrylic copolymer thickener. From EP 1 504 068 B1 corresponding aqueous micapigment pastes are known.
- a disadvantage of these effect pigment pastes is that a thickening agent must necessarily be used for their preparation, which in the production of paints such as waterborne paints using these pastes a comparatively high amount of water is required to set a sufficient viscosity, which in turn leads to an undesirable reduction of Solid body of the resulting paint leads.
- aqueous effect pigment paste which can be used to prepare a basecoat and which has advantages over the effect pigment pastes known from the prior art.
- the aqueous basecoats thus prepared should optimally fulfill the required application-technological properties, in particular a good optical appearance, sufficient flop and good adhesion properties, if not improve them, but in no case worsen them.
- the mixture (B) contains at least one polyunsaturated monomer and a polymer which is prepared from the mixture (B), a
- a further subject matter of the present invention is an aqueous basecoat, wherein the basecoat is preparable by admixing at least one effect pigment paste according to the invention as component (1) to at least one aqueous component (2) suitable for the preparation of a basecoat which contains at least one polymer usable as a binder, wherein this polymer which can be used as a binder is the polymer (b) also present in the effect pigment paste and / or at least one polymer which is different therefrom.
- the basecoats of the invention differ by this specific preparation of basecoats of the same composition, but on other Ways have been made in their properties such as the appearance of specks.
- Another object of the present invention is a process for producing a multi-layer coating, in which
- the substrate used in step (1a) preferably has an electrodeposition coating layer (ETL), more preferably an electrodeposition coating layer applied by cathodic deposition of an electrodeposition coating, and the basecoat used in step (1a) is applied directly to the ETL-coated substrate. wherein the electrodeposition coating layer (ETL) applied to the substrate is preferably cured when performing step (1a).
- ETL electrodeposition coating layer
- a further subject of the present invention is a use of the polymer (b) mentioned in connection with the first subject, ie a polymer having an average particle size in the range from 100 to 500 nm, preparable by successive free-radical emulsion polymerization of three monomer mixtures (A), ( B) and (C) of olefinically unsaturated monomers in water, wherein the mixture (A) contains at least 50% by weight of monomers having a solubility in water of less than 0.5 g / l at 25 ° C, and a polymer prepared from the mixture (A) has a glass transition temperature of from 10 to 65 ° C,
- the mixture (B) contains at least one polyunsaturated monomer and a polymer which is prepared from the mixture (B), a
- aqueous effect pigment paste according to the invention is distinguished by excellent storage stability and is therefore particularly suitable for use in automated production.
- the polymer (b) present in the aqueous effect pigment paste of the invention can be used not only as the main binder in aqueous basecoats, but can also be used as a paste binder in an aqueous effect pigment paste.
- improved formulation freedom is achieved since the other coating components of the basecoat do not have to be matched to a further paste binder other than the polymer (b) due to the now permitted use of the polymer (b) in the effect pigment paste.

- the individual polymerization stages in the preparation of the polymer (b) can be carried out, for example, as so-called “starving polymerizations” (also known as “starve feed”, “starve fed” or “starved feed” polymerizations).

In this case, a sample of the reaction solution is cooled immediately after sampling with liquid nitrogen and treated with 4-methoxyphenol as an inhibitor. In the next step, the sample is dissolved in tetrahydrofuran and then n-pentane is added to precipitate the polymer formed at the time the sample is taken.
- the liquid phase (supernatant) is analyzed by gas chromatography using a polar and a nonpolar column to determine the monomers and a flame ionization detector is used.
- Typical parameters for the gas chromatographic determination are the following: 25 m silica capillary column with 5% phenyl, 1% vinyl methyl polysiloxane phase or 30 m silica capillary column with 50% phenyl 50% methyl polysiloxane phase, carrier gas hydrogen, split injector 150 ° C, oven temperature 50 to 180 ° C, flame ionization detector, detector temperature 275 ° C, internal standard isobutyl acrylate.
- the determination of the concentration of the monomers is carried out in the context of the present invention preferably by gas chromatography, in particular while maintaining the above-mentioned parameters.
- the proportion of free monomers can be controlled in different ways.
- One way to keep the proportion of free monomers low is to choose the dosing of the mixture of olefinically unsaturated monomers to the actual reaction solution in which the monomers come into contact with the initiator, very low. If the metered addition rate is so low that all monomers can react almost instantly when in the reaction solution, it can be ensured that the proportion of free monomers is minimized.
- the metered addition rate is so low that all monomers can react almost instantly when in the reaction solution, it can be ensured that the proportion of free monomers is minimized.
- the reaction conditions are preferably to be selected so that the initiator feed is started even before the beginning of the metering of the olefinically unsaturated monomers.
- the dosage is started at least 5 minutes before, more preferably at least 10 minutes before.
- at least 10% by weight of the initiator particularly preferably at least 20% by weight, very preferably at least 30% by weight of the initiator, in each case based on the total amount of initiator, is added before starting the metering of the olefinically unsaturated monomers. It is preferable to choose a temperature which allows a constant decomposition of the initiator.
- the amount of initiator is also an important factor for the sufficient presence of radicals in the reaction solution. The amount of initiator should be chosen so that sufficient free radicals are available at all times so that the added monomers can react. If the amount of initiator is increased, even larger amounts of monomers can be reacted at the same time.
- the control of the proportion of free monomers can be controlled by the interaction of amount of initiator, rate of initiator addition, rate of monomer addition, and choice of monomers. Both the slowing of the dosage, as well as the increase in the amount of initiator, as well as the early start with the addition of the initiator serve the goal of keeping the concentration of the free monomers below the limits mentioned above.
- the concentration of the free monomers can be determined by gas chromatography as described above. Should this analysis determine a concentration of free monomers approaching the limit of starvation polymerization, for example due to low levels of highly reactive olefinically unsaturated monomers, the above parameters may be used to control the reaction.
- the metering rate of the monomers can be reduced or the amount of initiator can be increased.
- at least the polymerization stages ii. and iii. be carried out under starving conditions. This has the advantage of effectively minimizing the formation of new particulate matter in these two stages of polymerization.
