Definitions
- the present invention is a dispersant, a process for its preparation and its use.
- Polycarboxylates in particular in the form of polycarboxylate ethers are - in addition to polyacrylates, lignosulfonates, melamine sulfonates and naphthalenesulfonates - very widely used as dispersants (flow agents) for construction chemical preparations to reduce the water claim with otherwise the same composition or the processability at otherwise the same Improve composition.
- All of the dispersants mentioned are polyelectrolytes which, because of their charge carriers in the polymer, adsorb to the surfaces of the hydrating inorganic binders (for example cement, but also gypsum and anhydrite) and thereby alter the surface charge of the mineral particles (electrostatic dispersing mechanism).
- the hydrating inorganic binders for example cement, but also gypsum and anhydrite
- Comb polymers consist of a main chain ("backbone") along which the adsorptive functional groups - usually carboxylates - are arranged, and - in contrast to the other dispersants mentioned - from side chains, for example, from uncharged hydrophilic ethylene oxide These side chains have a large space requirement (sterically demanding) and thus additionally influence the dispersing action (steric dispersing mechanism) .
- the polymers adsorb via their anionic groups onto the positively charged areas of the binder particles, while the side chains in the mixing water
- the dispersing effect of the dispersants eg measurable by flow dimensions
- saturation dosage increases
- the dispersing effect of the dispersing agent increases (b) due to steric hindrance between the adsorbed amount of polyelectrolyte.
- polycarboxylate ethers in particular react very sensitively to changes in the mortar and concrete formulations, which has led to corresponding fine variations in the molecular structure and thus also to the known variety of suitable dispersants.
- Knowledge of the structure-activity relationship made it possible to produce a wide variety of tailor-made additives with a dispersing effect.
- compositions of the dispersants have different effects on the rheology of the building material mixtures and the hydration kinetics of the inorganic binder result.
- the temperature and the chemical composition of the construction mixture preparation influence the dispersion of the particles and, for example, the processability of a fresh mortar.
- the charge density of the flow agent must be comparatively high in order to be fully effective after a short time.
- the duration of the influence on the rheology with comparatively high charge density of the dispersant can be extended by increasing the total dosage of the dispersant. Under certain circumstances (with dispersant concentrations well below the saturation dosage), however, the initial flow rate is then also increased at the same time. On the other hand, the post-liquefaction can not be eliminated by increasing the fluid dosage.
- a disadvantage of the dispersants and dispersant combinations known hitherto is that the extent of dispersion can be controlled only with great difficulty, and the workability duration of the prepared construction-chemical compositions, as they are, for example, fresh mortar, can still be improved.
- This object has been achieved with a dispersant containing, as a dispersing component, the combination of
- (C) at least one representative of the uncharged copolymers in a proportion by weight of 0.1 to 20%.
- component (a), (b) and (c) representatives as dispersants is well known in particular from construction chemical applications. Also, the individual representatives are already extensively described as state of the art.
- the polycarboxylate ethers provided as component (a) are present as copolymers, for example in DE 10 2006 027 035 A1, US Pat. No. 7,070,648 B1 and WO 2006/133933 A2.
- the content of WO 2006/133933 A2 is a substantial part of the present disclosure with respect to the copolymers described therein.
- polycarboxylate ester variants (b) and their design options reference is made in particular to EP 0 753 488 B1, the content of which with respect to the dispersants described there is also a substantial part of the present disclosure.
- the third component, namely representatives of variant (c) can be found in the international patent application published as WO 2009/153202. The content thereof is also a substantial part of the present disclosure with respect to the dispersants described therein.
- polyacrylic acid derivatives which may have side chains, have initially no charge in pH-neutral aqueous solution and therefore do not adsorb to charged surfaces in a neutral solution, now also in dispersants in combination with other dispersing components can be used.
- the present invention also encompasses the use of uncharged components (c), such as, for example, polyacrylic acid derivatives alone or in combination with conventional polycarboxylates and / or polycarboxylate ethers and / or other dispersants (such as melamine sulfonates or naphthalenesulfonates) for construction chemical preparations (eg dry mortar based on inorganic binders such as Portland cement, Portland composite cement, alumina cement).
- inorganic binders such as Portland cement, Portland composite cement, alumina cement
- it is also conceivable to disperse other solids in basic solution eg, alkali-promoted granulated slag sand or anhydrite or pigments in alkaline solution.
- an advantage of the invention is that in this way the degree of dispersion can be controlled in several stages (eg, with simultaneous use of HPA and HEA).
- the dispersant combination according to the invention makes it possible initially to meter a flow agent outside of the saturation dosage and to compensate for the loss of processability inevitably due to the low dosage due to the onset of saponification of the initially uncharged component. As a result, a long-lasting uniform processability is achieved even at a moderate level with suitable flow agent formulation. The variety of advantages of the present invention was thus unpredictable.
- the dispersant according to the invention is preferably in powder form and in particular as a water-soluble powder.
- the water-soluble variant should be the rule.
- a "water-soluble powder” is understood to mean a powder from which at least 0.01% by weight dissolves in water at room temperature and which is preferred up to a concentration of 60% by weight in water 40 wt .-% in water, a clear single-phase solution without significant turbidity forms.When turbidity occurs in the water-soluble variant, these are usually drug-related or due to the polymers.
