Definitions

  • the present invention relates to a kit for producing a coating compound, a method for producing a coating compound, and the use of a coating compound for filling, brushing, rolling or spraying a surface.
  • Coating compounds are widely used in the construction industry, in trade and in the DIY sector.
  • coating compositions are used to protect surfaces from wear and tear and environmental influences, to connect or glue objects/structures together, to fasten objects, to fill gaps, cavities or cracks, to level surfaces, to create certain surface structures or to give surfaces a certain appearance to lend.
  • the physical, mechanical, chemical, optical and haptic properties of coating materials play a decisive role, as do their processability, curing, durability, transportability and health aspects.
  • US 5,162,060 A describes a coating composition for coating Portland cement concrete or metal.
  • the coating composition includes a polymer latex having ureido functional groups, an amine functional epoxy hardener, a liquid epoxy resin, and hydraulic cement.
  • the Coating composition can be made from two components. One component is a dry mixture containing hydraulic cement and epoxy resin, the other component is a wet mixture containing the polymer latex and the amine hardener.
  • a disadvantage of this two-component coating composition is that mixing of the two components can result in the formation of dust and that there is a large volume shrinkage when the coating composition cures.
  • kits known from the prior art for producing a coating composition are that dust is formed when the components are mixed and that there is a large volume shrinkage when the coating composition cures.
  • a further complication is that mixing solids into liquids is always associated with increased attention to the formation of lumps.
  • kits known from the prior art for producing a coating composition are that the coating compositions do not have high water resistance and/or that the modeling ability, grindability and/or the covering power of the coating compositions are insufficient and/or that mechanical properties are lost after curing such as bending strength and compressive strength are insufficient.
  • the object of the invention was therefore to provide a kit for producing a coating composition which at least partially overcomes one or more disadvantages of the prior art.
  • the kit should combine the advantageous properties of organic systems (flexible, good binding, variety of colors thanks to organic pigments, easy processing, universal adhesion to various substrates, very dense film formation) and inorganic systems (hard, chemically hardening, little volume shrinkage, resistant).
  • organic systems flexible, good binding, variety of colors thanks to organic pigments, easy processing, universal adhesion to various substrates, very dense film formation
  • inorganic systems hard, chemically hardening, little volume shrinkage, resistant
  • a coating composition produced from the kit should have as little volume shrinkage as possible and, after curing, should have advantageous mechanical properties such as high flexural strength and compressive strength. Furthermore, a coating composition produced from the kit should have high water resistance. Finally, a coating composition produced from the kit should have good modeling ability, sandability and/or high hiding power.
  • a further object of the present invention was to provide a method with which a coating composition with the properties described can be produced.
  • the method should be fast and efficient.
  • kit according to claim 1 a method according to claim 36, a coating composition according to claim 39, a use according to claim 42 and a use according to claim 44.
  • the invention provides a kit for producing a coating composition containing a component 1 and a component 2, where component 1 contains at least 40% by weight inorganic filler, based on the total weight of component 1, epoxy resin hardener and water, and component 2 contains hydraulic Binding agent (particularly cement) and epoxy resin, components 1 and 2 being independently liquid or pasty at room temperature.
  • component 1 contains at least 40% by weight inorganic filler, based on the total weight of component 1, epoxy resin hardener and water
  • component 2 contains hydraulic Binding agent (particularly cement) and epoxy resin, components 1 and 2 being independently liquid or pasty at room temperature.
  • inorganic filler at least 40% by weight of inorganic filler, based on the total weight of component 1, means that the coating composition has particularly advantageous properties.
  • a proportion of inorganic filler ensures that there is little or no volume shrinkage during curing of the coating composition.
  • the structure, the filling effect, the surface structuring and the fastening properties of the coating compound are retained during curing.
  • such a proportion of inorganic filler ensures that the coating composition has high flexural strength and compressive strength after curing.
  • such a proportion of inorganic filler ensures that the coating composition has good modeling ability, grindability and high hiding power.
  • components 1 and 2 are each independently liquid or pasty at room temperature. This prevents the formation of dust when mixing component 1 and component 2, which can lead to health problems, cleaning effort and material loss.
  • epoxy resin refers here to one or more chemical compounds that carry at least one epoxy group and can be reacted with a hardener to form a plastic.
  • An epoxide group is understood to mean a three-membered ring in which, in comparison to cyclopropane, a methylene group is replaced by an oxygen atom. The carbons of the epoxide group can be substituted.
  • the term “epoxy resin” also includes, in particular, reactive diluents with at least one epoxy group.
  • the epoxy resin is preferably liquid.
  • epoxy resin hardener refers to one or more chemical compounds capable of curing the epoxy resin. This means that the epoxy resin hardener is able to react with the epoxy group(s) of the epoxy resin. In particular, the curing takes place by addition reactions.
  • Component 1 of the kit according to the invention preferably contains, in each case based on the total weight of component 1, 40% by weight to 95% by weight, in particular 50% by weight to 80% by weight or 65% by weight to 75% by weight, inorganic Filler, 0.05% to 5% by weight, in particular 0.1% to 3% by weight or 0.3% to 1% by weight, epoxy resin hardener, and 5% to 40% by weight wt.%, in particular 10 wt.% to 30 wt.% or 15 wt.% to 25 wt.%, water.
  • Such a composition ensures a particularly good combination of the properties of inorganic systems with those of organic systems and ensures high flexural strength and compressive strength with, at the same time, high elasticity of the coating composition.
  • the inorganic filler in component 1 is a silicate, carbonate, sulfate, oxide, hydroxide, or a mixture thereof, in particular a silicate, alkali metal carbonate, alkaline earth metal carbonate, alkali metal sulfate, alkaline earth metal sulfate, metal oxide, metal hydroxide, or a mixture thereof .

  • Such an inorganic filler ensures that there is little or no volume shrinkage during curing of the coating composition. As a result, the structure, the filling effect, the surface structuring and the fastening properties of the coating compound are retained during curing.
  • such an inorganic filler ensures that the coating composition has high flexural strength and compressive strength after curing. Furthermore, such an inorganic filler ensures that the coating composition has good modeling ability, grindability and high hiding power.

  • a lower proportion of inorganic filler increases the volumetric shrinkage during curing of the coating composition.
  • a small proportion of inorganic filler reduces the flexural strength and compressive strength of the cured coating composition and leads to reduced hiding power.
  • a higher proportion of inorganic filler can lead to hardening incomplete. Furthermore, adhesion to substrates/surfaces and general workability could be impaired by a higher proportion of inorganic filler.
  • the epoxy resin hardener in component 1 is an amine, in particular an amine with several N-H bonds and/or a polyamine polymer.
  • an epoxy resin hardener is particularly suitable for curing the epoxy resin.
  • the amino groups can react with the reactive epoxy groups of the epoxy resin in an addition reaction and thus crosslink it. This gives the coating mass a particularly high level of stability.
  • Several functional amino groups within the epoxy resin hardener ensure greater cross-linking and thus greater stability and improved mechanical properties of the cured coating composition, such as greater flexural strength and compressive strength with high elasticity at the same time.
  • the epoxy resin hardener in component 1 is a polyoxyalkylene polyamine, an arylene polyamine, a cycloaliphatic polyamine, a poly-aza-alkane, a Mannich base or a mixture thereof.

  • Equivalent mass ratio means the ratio of the total number of reactive groups of the epoxy resin hardener to the total number of reactive groups of the epoxy resin. For example, with an equivalent mass ratio of 1:1, there is exactly one reactive group in each case Epoxy resin hardener (e.g. amino group) per reactive group of the epoxy resin (epoxide group).
  • the epoxy resin hardener in component 1 has an equivalent mass ratio to the epoxy resin in component 2 of from 1:10 to 10:1, in particular from 1:2 to 2:1 or from 1:1.2 to 1.2:1 or from about 1 :1, particularly good and uniform crosslinking and curing of the coating composition can occur. If the equivalent weight ratio is too high or too low, crosslinking and curing are incomplete, with the result that the mechanical properties and adhesion of the coating composition deteriorate.

  • epoxy resin hardener enables the coating composition to harden particularly well. Too little epoxy resin hardener leads to incomplete curing of the coating composition and thus to poorer mechanical properties and poorer adhesion. Too much epoxy resin hardener will result in lower flexural strength and compressive strength of the cured coating.
