Description

Coating compositions based on universal pigment preparations

The invention relates to coating compositions comprising at least one solvent-containing binder, an aqueous universal pigment preparation and optionally auxiliaries and additives.

The coating compositions are used as paints, varnishes, adhesives, inks or printing inks for the coating of objects from e.g. As metals and plastics. The coating compositions are suitable for all customary application methods which are used in modern metal and plastic coating and the printing ink industry, such as, for example, As the spray application, the electrostatic spray application and printing by means of various printing processes.

Usually, colored coating materials are prepared in such a way that first a pigment preparation is produced, which is then lacquered with a base lacquer.

In the preparation of pigment preparations, fillers and pigments are dispersed in liquid media. For this purpose, it is generally used dispersants, so as to reduce the mechanical shear forces required for effective dispersion of the solids and at the same time to achieve the highest possible fill levels. The dispersants promote the breaking up of agglomerates, wet and / or occupy the surface of the particles to be dispersed as surface-active compounds and stabilize them against undesired reagglomeration.

Wetting agents and dispersants facilitate the incorporation of pigments and fillers in the production of paints and varnishes, which, as important formulation constituents, improve the visual appearance and the physico-chemical properties Significantly determine the properties of coatings. For optimum utilization, these solids must be evenly distributed in paints and varnishes, on the other hand, the distribution once achieved must be stabilized. The stabilizing component is also often perceived by binder components. Such binders are also valuable components for coating materials because they contribute to faster drying and increasing the hardness of the resulting films.

For solvent-based coating materials usually solvent-based pigment preparation based on various wetting and dispersing agents are prepared, which are dissolved with various solvent-based masterbatches. For aqueous coating materials, it is customary to prepare aqueous pigment preparations based on various wetting agents and dispersants, which are then dissolved with various aqueous masterbatches.

It would be desirable to have universal pigment preparation to avoid the high cost of producing and storing many pigment preparations.

First of all, a universal compatibility with other binders is important for use in universal pigment preparations. B. with the significant Langölalkydharzen, vegetable oils, hydrocarbon resins, acrylate resins and polyamides - secondly, and a universal solubility in organic solvents such. B. in the often used for ecological and toxicological reasons pure aliphatics and white spirits. Such binders which can be used in pigment preparations with universal compatibility and solubility are described, for example, in US Pat. As described in DE 44 04 809.

As dispersants for universal pigment preparations, in particular alkylphenol ethoxylates or fatty alcohol alkoxylates are used which form a steric

Stabilization of achieved pigment distributions contribute. The very powerful Alkylphenol ethoxylates have come under criticism for ecotoxicological reasons. Their use in detergents and cleaners is already banned in many countries. Similar things are expected for the paint and paint industry. In many cases, fatty alcohol ethoxylates do not achieve the good pigment-wetting properties of the alkylphenol ethoxylates because they lack adsorptive groups. In particular, the non-adsorbed part of this product group also undesirably stabilizes the foam in aqueous pigment preparations.

Block Copolymers Polyalkylene oxides are toxicologically harmless, strongly adsorptive but less foam-stabilizing. They are z. B. in the

EP 1 078 946. However, a complete precipitation of the foaming can not reach these products. Therefore, the aqueous

Pigment preparations are added here also defoaming active substances. However, these substances have other negative side effects, such as unwanted surface defects. The use of many dispersing additives is ruled out since the water resistance or the light resistance of coatings is adversely affected.

PCT / EP2006 / 050437 describes pigment preparations based on the combination of block copolymers, styrene oxide-containing polyalkylene oxides and ketone-aldehyde resins, which have a broad compatibility with binders used and solubility in organic solvents used and in water, wherein the foaming is suppressed in aqueous pigment preparations , Such solvent-containing pigment preparations are outstandingly suitable for the preparation of solvent-containing and-when using suitable solvents, such as glycols-aqueous coating materials. In addition, PCT / EP2006 / 050437 describes the use of aqueous pigment preparations for the production of purely aqueous coating materials with outstanding properties.

The present invention therefore an object of the invention to find coating compositions, which by the use of solvent-containing, pigmented or unpigmented masterbatches and an aqueous Universalpigmentpäparation be prepared.

Thus, the known good technical properties of solventborne binders could be made more environmentally friendly by the use of aqueous pigment preparations.
