Definitions

  • the invention relates to the use of a fluorine-free coating composition, a fluorine-free coating composition and a floor covering coated with the coating composition.
  • oils or waxes are therefore used as impregnating agents for floor coverings, which in particular repel water or aqueous solutions.
  • these materials do not dry completely, only offer superficial protection or are not long-lasting.
  • waxes are very difficult to apply. The result is high layer thicknesses, meaning that the individual panels cannot be properly connected to each other.
  • the materials used often contain fluorine, which is harmful to both the environment and users.
  • the coating agent for floor coverings, especially for interior areas, which can be applied to the edge area of floor covering elements or over the entire surface and offers sufficient protection against water and cleaning chemicals.
  • the coating materials should be fluorine-free for environmental reasons. They should be easy to apply and penetrate the soil material sufficiently.
  • This problem could be solved by using a fluorine-free coating composition to impregnate floor coverings.
  • This contains at least one polycarbodiimide compound a, preferably the at least one polycarbodiimide compound having at least two hydrocarbon groups, each of which has at least 4 carbon atoms, preferably at least 12 carbon atoms, preferably at least 16 carbon atoms.
  • composition used according to the invention is used to increase the water-repellent effect of substrates.
  • a “fluorine-free” coating composition means that a composition used for waterproofing contains less than 1% by weight (1% by weight) of fluorine in a composition.
  • a “fluorine-free” coating composition means that a coating composition preferably contains less than 0.5% by weight, less than 0.1% by weight or less than 0.01% by weight.
  • the fluorine can be in the form of organic or inorganic fluorine-containing compounds.
  • the polycarbodiimide compounds have at least two hydrocarbon groups, each containing at least 4 carbon atoms.
  • the at least one polycarbodiimide compound is derived from a carbodiimidization reaction of a carbodiimidization reaction mixture comprising at least one oligomer, the oligomer comprising at least one isocyanate end group and at least two repeating units, each of the at least two repeating units having at least one hydrocarbon group of at least 4 includes carbon atoms.
  • the polycarbodiimide compound is derived from a carbodiimidization reaction of a carbodiimidization reaction mixture comprising 4,4'-methylene bis(phenyl isocyanate) and an acrylate oligomer in a molar ratio of 2:1 to 10:1, wherein the acrylate oligomer is derived by reacting an oligomerization reaction mixture comprising mercaptoethanol and octadecyl acrylate in a molar ratio of 1:4 to 1:20, or an oligomerization reaction mixture comprising mercaptoethanol and a reaction product of octadecyl isocyanate with 2-hydroxyethyl (meth)acrylate or octradecyl isocyanate with 2-isocyanatoethyl (meth)acrylate, where the mercaptoethanol and the reaction product are reacted in a molar ratio of 1:4 to 1:20.
  • Oligomers include compounds with at least 2 and up to 20 repeating units. According to a particular embodiment, the oligomer has 3 to 15 repeating units. According to another embodiment, the oligomer has 4 to 15 repeating units. In certain embodiments, an oligomer has a weight average molecular weight of up to 50,000 g/mol.
  • the composition comprises at least one paraffin wax b.
  • the paraffin wax has a melting point of 40°C to 75°C.
  • the paraffin wax has a melting point of 60°C to 75°C.
  • the mass ratio of paraffin wax b to polycarbodiimide a is preferably 3:7 to 7:3, preferably 5:5 to 7:3.
  • the proportion of polycarbodiimide compound and paraffin wax in the composition is preferably 1 to 20% by weight, based on the total weight of the composition.

  • the proportion of the polymer is preferably 5 to 40% by weight, based on the total weight of the composition.
  • the polymers can carry anionic groups, for example sulfonic acid groups.
  • the alkyd resin can be, for example, a long oil or medium oil alkyd.
  • Long oil alkyds are alkyd resins with a fatty acid content of more than 60%; Middle oil alkyds contain 40 to 60% fatty acids. Suitable fatty acids are, for example, vegetable fatty acids.
  • the acid number is preferably less than 20 mg KOH/g; the iodine number is preferably less than 20.
  • the alkyd resin may or may not be urethane or isocyanate modified to promote water resistance.
  • the advantage is threefold: In addition to the price advantage, the alkyd not only ensures increased viscosity, but especially with a medium or long chain resin, it penetrates less deeply into the wood and can create an initial barrier due to its low dispersion.
  • the resin forms an outer film. Since a relatively thin layer is applied, the coating does not need to be dried in order to comply with current ecological standards (AgbB, etc.).
  • Acrylate resins can include pure acrylates or styrene acrylates. Suitable monomers are, for example, methyl methacrylate, styrene, acrylonitrile, butyl methacrylate, ethyl acrylate, buthyl acrylate or ethylhexyl acrylate.

They can carry alkyl, alkenyl such as vinyl, aryl such as phenyl, amino, alkoxy or H groups in the side groups. The alkyl groups are preferred, with methyl (polydimethylsiloxane PDMS), methoxy or ethoxy groups being particularly preferred.
  • Suitable siloxanes are offered, for example, by Dow Corning (USA) - Dowsil products, Evonik (Germany) - Tegophobe 6600, Wacker (Germany) - TES28, Momentive (USA) - Silquest products. The aforementioned polymers can be used in particular in the form of solutions or dispersions.
  • the mass ratio of (polycarbodiimide compound a + paraffin wax b): polymer c is 10:90 to 90:10, preferably 70:30 to 95:5.
  • the coating composition preferably comprises at least one solvent d.
  • solvent d include both water and organic solvents, with water or aqueous mixtures being preferred.
  • Water and aqueous mixtures are advantageous because they are particularly environmentally friendly.
  • Solvent mixtures are preferably homogeneous. Suitable organic solvents are alkanes including branched alkanes, preferably with 10 to 20 carbon atoms, alcohols with 1 to 6, preferably 1 to 4 carbon atoms and esters such as acetates from alcohols with 1 to 10 carbon atoms. Ethyl acetate is less preferred because it is explosive. Hydrophilic organic solvents that are miscible with water, such as alcohols, are particularly suitable for aqueous mixtures. The proportion of solvent is preferably 20 to 95% by weight, based on the total weight of the composition.
  • Alkyd resins, silanes or siloxanes are particularly chosen as polymers for water-free coating agents.
  • Aqueous coating compositions preferably contain acrylate resins, polyurethane-modified polyesters, silanes or siloxanes as polymers.
  • the coating composition may contain adjuvants such as surfactants, surface-active agents, coalescing solvents, antifreezes, emulsifiers or stabilizers against one or more microorganisms. Suitable aids are disclosed in US 11124918 B2. It is preferred that the coating composition is homogeneous. The proportion of auxiliaries is preferably 0.1 to 20% by weight, based on the total weight of the composition
  • the coating composition may contain 1 to 10% by weight, based on the total weight of the composition, of colorants such as dyes or pigments. These can, for example, cover up the lines created during milling or the appearance of different materials. In particular, these colorants should have no influence on water resistance and repellency.
  • the individual components can be added and mixed together, for example using a stirrer.
  • the individual components can be dissolved in suitable solvents beforehand.
  • Suitable substrates are floor coverings, with indoor coverings being preferred. These include homogeneous or heterogeneous plastic coverings, for example comprising polyvinyl chloride, polyolefins, rubber, linoleum or quartz vinyl. Cork is also suitable. The previously mentioned coverings are elastic coverings. Laminate floors, parquet including finished parquet and plank floors can also be included. The latter are hard surfaces.
