Definitions
- the invention relates to a polymer which can be used as a dispersant, a process for the preparation of the polymer and the use of the polymer as a dispersant, in particular for pigments and fillers, for example.
- pigment pastes and coating compositions such as paints and varnishes.
- pigment particles which are contained in these must form a stable dispersion, ie be distributed homogeneously and as small as possible primary particles.
- the dispersed pigment particles on the one hand must be well wetted by the solvent, on the other hand, the pigment particles must be prevented from re-agglomeration, so that formation of larger agglomerates is suppressed, which would rapidly decrease in the solvent.
- the surface of pigment particles or of the fillers used in the coating composition can range from very polar to very nonpolar. In order to achieve compatibilization of the particles with the solvent or binder, therefore, dispersants are used. These must be on the one hand with the surface - -
- the dispersant must therefore have in the molecule areas that are well compatible with the solvent or binder. If organically based systems are used, for example hydrophobic structures, such as alkyl, polyester or aryl groups, can be provided in the molecule of the dispersant.
- the compatibilizing portion is usually composed of polyethylene glycols or of polymerized monomers having (salified) carboxylic acid groups.
- the polar surface of an inorganic pigment particle may be coated with a polymer having polar portions that bind to the polar surface of the particle, as well as nonpolar portions that provide compatibility with the solvent.
- Polar regions can be generated, for example, by providing in the polymer (tertiary) amino groups, phosphoric acid ester groups or carboxylic acid groups.
- the polar surface of the pigment particle is therefore coated with a shell, which has more non-polar properties compared to the surface of the pigment particle.
- the surface of the pigment particles thus becomes more similar in polarity to that of the solvent or binder. In this way, the pigment particles can be wetted by the solvent and dispersed so that they are homogeneous and finely divided, do not float on the solvent and do not settle.
- the polymer also contains sterically demanding groups which hinder the individual pigment particles from agglomerating due to steric hindrance.
- EP 1197 536 A2 describes a composition which can be used as a dispersant for pigments.
- the composition contains a graft polymer having an average molecular weight of about 5,000 - 100,000 and that Polymer backbone, as well as derived from the backbone anionic and nonionic hydrophilic side chains. Compared to the side chains, the polymer backbone has hydrophobic properties and contains polymerized ethylenically unsaturated hydrophobic monomers and, based on the total weight of the polymer backbone, in an amount of up to 30% by weight of polymerized ethylenically unsaturated monomers carrying functional groups can increase the binding power of pigments.
- the anionic side chains are formed by hydrophilic macromonomers prepared from polymerized ethylenically unsaturated monomers and containing, based on the total weight of the anionic side chain, 2-100% by weight of a polymerized ethylenically unsaturated acidic monomer.
- the nonionic side chains are formed by hydrophilic ethylenically unsaturated macromonomers containing polyalkylene glycols.
- EP 1 293 523 A2 describes a water-based pigment dispersion which can be used for the production of aqueous compositions for coatings and which contains a dispersed pigment, an aqueous carrier and as dispersant a branched polymer.
- the polymer used as a dispersant has a weight average molecular weight of about 5,000 to 100,000 and comprises 20 to 80% by weight of a hydrophilic backbone and 80 to 20% by weight of macromonomer side chains.
- EP 0 311 157 A1 describes a polymer which can be used as a dispersant. It is composed of (A) 0 to 80 mol% of a styrene derivative, (B) 0 to 70 mol% of an acrylate or methacrylate derivative, (C) 5 to 50 mol% of a monomer containing a heterocyclic group containing at least one basic nitrogen atom in the ring, (D) 0-10 mol% of a monomer comprising a group capable of causing cross-linking or coupling, and 0 to 20 mol% of a monomer not included in the groups (A ) to (D), wherein the proportion of the monomers of group (A) and the monomers having an acrylate group at least 20 mol%.
- R> 5 H or an alkyl group having 1 to 6 carbon atoms
- Non-polar groups are introduced into the polymer via the repeating unit indicated by the index b via the group R 3 .
- An aralkyl group is understood as meaning an aryl group which is substituted by at least one alkyl group or alkylene group, such as a methyl group or a methylene group.
- R 3 is particularly preferably a phenyl group or a phenyl group substituted by one or more methyl or isobutyl groups.
- R 1 , R 2 , R 3 , R 4 , a, b and c have the abovementioned meaning.
- the polymerization can be carried out batchwise, d. H. the starting materials are initially charged in a reaction vessel and the reaction started by addition of a radical initiator. However, it is also possible to carry out the reaction in the feed process, all or part of the educts being introduced into the reaction vessel during the reaction.
- Fig. 3 is a graphical representation of the orientation parameters for Iriodin 225 ® in an aqueous acrylate paint upon addition of the polymer of the invention
- Fig. 4 is a graphical representation of the orientation parameters for Iriodin 225 ® in a solvent-based polyurethane paint upon addition of the polymer of the invention.
- the sedimentation of the pigments could be slowed down.
- the degree of stabilization also depends on the concentration of the polymer.
- the orientation parameter L25 / L75 was used, wherein L25 and L75 were determined colorimetrically at the angles 25 ° and 75 ° in the gyroscopic method. The larger and more uniform the orientation parameter, the better the horizontal orientation of the pigment particles. Ideally, the values of the orientation parameter form a circle. The results of the measurements of the orientation parameter are shown in FIGS. 3 and 4.
