Definitions
- the present invention relates to a process for the preparation of pigment and / or filler-containing formulations using aqueous cationically stabilized primary dispersions containing polymer particles having an average particle diameter of 5 to 500 nm (so-called polymerized "miniemulsions”) the
- pigment pastes or filler pastes which contain pigments in high concentration in predispersed form.
- Predispersion is generally carried out using polymeric binders which, on the one hand, are intended to wet the pigment surfaces and, on the other hand, have good compatibility with the coating systems in which the pastes are used later.
- the binders used to prepare the pigment and / or filler preparation correspond to the principal binders of the paint systems in which they are used.
- the principal binders of the pigmented and / or filler-containing paint systems are unsuitable for effectively disaggregating the pigments and / or fillers and preventing reagglomeration.
- the use of so-called special friction resins in the preparation of the pigment and / or filler preparations is recommended.
- the amine-modified aromatic epoxy resins frequently used as main binders in the production of electrodeposition paints are less suitable in terms of their wetting properties to wet pigment and / or filler surfaces.
- Reibharze be used.
- Electrocoating lacquers are aqueous coating agent systems which are applied cathodically or anodically, preferably cathodically, by the process of electrocoating.
- the main binders used in cathodically depositable electrodeposition paints are generally aqueous dispersions based on epoxy-amine resins. In some cases, however, amine-functionalized acrylate resins are also used
- WO 82/00148 discloses the preparation of cathodically depositable primary dispersions using cationically adjustable emulsifiers.
- the emulsifiers can carry reactive groups, by means of which they can be incorporated into the polymeric resin system during the crosslinking reaction.
- Explicit examples of emulsifiers are the acetic acid salts of fatty mono- and diamines such as primary tallow and oleylamines or the acetic acid salts of tallow and oleyl diamines. Tallow and oleylamines contain hydrocarbon chains having at least one carbon-carbon double bond. Also polymers
- Emulsifiers can be used, such as an epoxy-phenol adduct which has been reacted with diethanolamine and cationically adjusted with acetic acid.
- Ethoduomeen TM T13 is used, which is a tertiary amine with unsaturated
- Mini-emulsions are dispersions of water, an oil phase and one or more surface-active substances, wherein the dispersed particles present have an average particle diameter of 5 to 500, preferably 25 to 500 and particularly preferably 50 to 500 nm. Mini-emulsions are considered to be metastable (See Emulsion Polymerization and Emulsion Polymers, Editors, PA Lovell and Mohamed S.

- the monomers can be copolymerized in the presence of different low molecular weight, oligomeric or polymeric hydrophobic substances or co-stabilizers (cf DE 196 28 142 A 2).
- hydrophobic, sparingly soluble in water, organic aids such as plasticizers, film-forming aids such as coalescing agents, or other organic additives can be incorporated into the monomer droplets of the miniemulsion (see DE 196 28 143 A1).
- WO 82/00148 describes the use of emulsifiers for stabilizing the emulsions disclosed therein.
- Aminoethylmethacrylat monomers wear a positive surface charge and thereby stabilized in the dispersion.
- the saturated cetyl methylammonium bromide can be used, which has a quaternary nitrogen atom and therefore carries a permanent positive charge. The positive charge is compensated in both cases by halide anions.
- An object of the present invention is to provide a process for preparing a pigment and / or filler-containing formulation.
- the formulations containing the pigment and / or filler obtainable by the process should be usable in aqueous coating compositions and give them improved long-term stability.
