Embodiment

[0122] 1) Preparation of styrene oxide-containing polyoxyalkylene (component I.A))

[0123] 336.4 g (2.34 mol) of trimethylcyclohexanol and 16.3 g (0.23 mol) of potassium methoxide were charged into a reactor. After careful purging with pure nitrogen, the initial charge was heated to 110° C. and then 308.2 g (2.554 mol) of styrene oxide were added over a period of 1 h. After a further 2 h, the addition of styrene oxide was complete, as indicated by gas chromatography with a residual styrene oxide content of less than 0.1 wt%. Subsequently, 339.2 g (7.71 mol) of ethylene oxide were rapidly metered into the reactor at such a rate that the internal temperature did not exceed 120° C. and the pressure did not exceed 6 bar. After the introduction of ethylene oxide was complete, the temperature was maintained at 115°C until a constant gauge pressure indicated the end of the subsequent reaction. Finally, at 80-90°C, unreacted residual monomers were removed under vacuum. The product...

Abstract

The invention relates to novel universal pigment preparations with an extremely good thermal resistance and weather resistance, used as practically foam-free aqueous pigment preparations that contain or are devoid of solvents. The invention also relates to the use of said preparations in aqueous coating substances that contain or are devoid of solvents, such as for example, paints, lacquers, adhesives, inks or printing inks and for colouring synthetic materials.

Description

technical field [0001] The present invention relates to a new universal pigment preparation with very good thermal and weather stability as a practically foam-free aqueous as well as solvent-containing and solvent-free pigment preparation and to its use in aqueous, solvent-containing or solvent-free In coatings, for example, dyes (Farben), lacquers, adhesives, inks or printing inks, and for the coloring of plastics. Background technique [0002] Dispersion of fillers and pigments in liquid media is usually achieved with the use of dispersants in order to reduce the mechanical shear forces required for effective dispersion of solids while also achieving the highest possible filling levels. Dispersants aid in the breakdown of agglomerates, act as surface-active compounds to wet and / or coat the surface of the particles to be dispersed, stabilize these particles and prevent unwanted re-agglomeration. [0003] In the production of dyes (Farben) and lacquers, wetting and dispersi...
