Definitions

  • the present invention relates to a dispersion-based coating using calcium hydroxide for pH control.
  • Pure silicate dyes are two-component colors that contain no organic components.
  • the two main components are water glass and water glass resistant pigment and fillers.
  • Dispersion silicate dyes according to DIN 18363 contain, in addition to the water glass and the pigment / filler mixture, up to 5% by weight of organic constituents, based on the total amount.
  • Emulsion paints usually contain resin dispersions for setting. In order to ensure a sufficient Lagerstabili ity require emulsion paints Topfkonser multungsstoff, in which case the use of isothiazolinones is common. These can cause irritation and irritation of the skin in susceptible persons.
  • the publication DE 10 2016 002 221 A1 describes a combination of 1 to 15% by weight of pigment with 30 to 60% by weight of filler, 1 to 25% by weight of polymer, 0.1 to 3.5% by weight.
  • German Offenlegungsschrift DE 10 2014 013 455 A1 finally describes a preservative-free dispersion paint based on siliconate, the proportion of the silicic acid being between 0.5 and 5%, preferably between 1 and 3%, and thus no preservatives are required in the still good ones Storage stability of over 6 months, even if the silicone additive is in the lower range.
  • the object of the present invention is to formulate a Beschich tion on a dispersion basis covering the entire gloss range of the dispersion coatings, this is free of preservatives and at the same time has a very good shelf life and processing properties.
  • the inventive coating on Dispersionsba sis has a pH of 10.5-12 and contains based on the total recipe the following components: a) 0.1 to 30% by weight of pigment, b) 15 to 65% by weight of filler, c) 1 to 35% by weight of polymer, d) 0.01 to 1% by weight of calcium hydroxide e) 5 to 70% by weight of water.
  • the coating according to the invention contains on dispersion basis 0.1 to 30 wt .-% pigment.
  • a pigment here are various substances in question.
  • the pigment is selected from the group consisting of titanium dioxide, iron oxide yellow, bismuth vanadate, rutile tin zinc, quinacridones, iron oxide red, phthalocyanine blue, dioxazine, cobalt blue, ultramarine blue, phthalocyanine green, chrome oxide green, cobalt green, color black, iron oxide black, pyrazolo quinazolone, monoazo pigment and mixtures thereof.
  • the coating according to the invention contains 10 to 65% by weight of filler based on dispersion.
  • filler consisting of dolomite, barium sulfate, feldspar, quartz, calcium carbonate, mica, kaolin, calcined kaolin, talc, diatomaceous earth and mixtures.
  • the dispersion-based coating contains 1 to 35% by weight of polymer, based on the total recipe.
  • the information relating to the content of polymer relate in each case to the polymer as a solids content.
  • the polymer is preferably added during the preparation in the form of a dispersion.
  • the polymer of the coating according to the invention preferably comprises at least one polymer and / or copolymer based on at least one monomer selected from the group consisting of acrylic acid, acrylic acid derivatives, acrylic esters, methacrylic acid, methacrylic acid derivatives, methacrylic acid esters, styrene, styrene derivatives, N-vinylpyrrolidone, acrylonitrile , Vinyl acetate, vinyl propionate, ethylenically unsaturated carboxylic acids, ethylenically unsaturated carboxylic acid esters, ethylenically unsaturated carboxylic acid anhydrides, ethylenically unsaturated carboxylic acid amides and carboxylic acid vinyl esters.
  • Dispersionsba sis may also contain as further additives dispersants, wetting agents, thickeners, stabilizers, defoamers and / or Hydropho b istsstoff.
  • thickeners are alcohol alkoxylates, ethylene oxide-propylene oxide copolymers, maleic anhydride-diisobutylene copolymers, polyacrylic and polymethacrylic acid and salts thereof, methylcelluloses, carboxymethylcelluloses, hydroxymethylcelluloses, polyurethanes, alkali metal phosphates and salts of modified phosphoric acids , as well as their mixtures.
  • defoamers are polyglycols, triglycerides, polysiloxane-polyether copolymers and silicone oils.
  • water repellents are in particular oligomeric and polymeric siloxanes and silicone resins.
  • the coating according to the invention on Dispersionsba sis is suitable for a variety of uses. In particular, it is suitable for use in the interior and / orjonbe rich and on different substrates.
  • the dispersion-based coating thus obtained covers the entire gloss range of the dispersion coatings, is free from preservatives and also has a very good shelf life and processing properties.
