Embodiment Construction

[0061] Dispersion pigments having the following formulations shown in Table 1 were produced by mixing the components shown in Table 1, the amounts in each being % by weight.

[0062] Table 1

[0063] components Formula A Formula B Titanium dioxide 6 11 Styrene Acrylate (50% by weight in water) 19 11 Potassium methyl silicate 1 1.5 calcium carbonate 21.7 32.5 Kaolin 20.8 8 basic compound 0.05 0.5 Defoamer 0.2 0.28 thickener 0.5 0.75 humectant 0.46 0.3 water 30.29 34.17 pH value 11.3 11.4

[0064] Formulations A and B showed storage stability over 6 months without discoloration and processed well. These formulations in particular exhibit good processability and produce surfaces with a homogeneous overall appearance after application. After 6 months the pH of Formulation A was 11.3 and that of Formulation B was 11.4.

Abstract

The present invention relates to a dispersion pigment, which comprises, based on the total weight of the dispersion pigment, a) 1 to 15% by weight of pigment, b) 30 to 60% by weight of filler, c) 1 to 25% by weight of Polymer, d) 0.1 to 3.5% by weight of an alkali metal alkyl siliconate, e) 25 to 70% by weight of water, wherein the pH of the dispersion pigment is 10 to 12. In addition, the production method of the dispersion pigment is described. The dispersion pigments are suitable for use in interior or exterior areas.

Description

technical field [0001] The present invention relates to a dispersion pigment, a method for producing the dispersion pigment, the use of the dispersion pigment and the use of an alkali metal alkyl silicon alkoxide for stabilizing the dispersion pigment. Background technique [0002] Various coating agents are known for the coating of substrates. In addition to silicate pigments, there are dispersion silicate pigments and artificially synthesized dispersion pigments. [0003] Silicate pigments are two-component pigments that contain no organic components. The two main components of silicate pigments are the pigments of water glass and water resistant glass. Silicate pigments are usually mixed by bringing the two main components together directly before application. Silicate pigments therefore require several working steps and their processing is often difficult and requires a great deal of experience. [0004] In the dispersed silicate pigments according to DIN 18363, a ma...
