Definitions

  • Epoxy resin has the property of reacting very quickly. For this reason, one must work very carefully on the one hand, i.e. care must be taken to ensure that the epoxy grout only reaches the joint to be processed and not the tiles immediately adjacent to it. If the grout is still on the tile, it must be removed immediately, because otherwise it can no longer be removed or only with great effort. But even if the processor responds immediately, removal is only possible with great difficulty.
  • CH-PS 670 832 describes an organic, chlorohydrocarbon-free stripping, solvent and paint remover which is composed of a resin solvent from the group of the esters, a swelling agent from the group of oxygen heterocycles, a solvent for surfactants and thickeners, one or more surfactants from the group of alkylbenzenesulfonates and one or more thickeners from the group of alkylhydroxyalkylcelluloses, the agent containing one or more aprotic or non-aprotic polar solubilizers. Only organic solvents or solubilizers are used to achieve homogeneous mixing of the components. However, these organic solvents are undesirable for reasons of environmental protection and efforts are being made in the development of cleaning agents to greatly reduce their proportion or to dispense with them entirely.
  • US-A-2,064,725 relates to an aqueous detergent composition which contains a soap and at least one organic solvent, for example ethyl acetate, butyl acetate, pentyl acetate, which serves as a paint solvent.
  • This detergent composition is suitable for removing cellulose lacquer layers, paints, enamel lacquers, glazes, printing inks and similar materials from the skin without affecting them too much when the agent is used.
  • the composition In order to achieve a suitable cleaning effect, the composition must additionally contain an abrasive.
  • Such an abrasive-containing detergent composition can only be used for purposes in which the abrasive effect of the abrasive cannot cause any damage to the surface to be cleaned.
  • the invention has for its object to facilitate the cleaning of smeared with epoxy resin tiles.
  • aqueous emulsion which contains a soap and a suitable organic solvent for hardened epoxy resins, the proportion of the soap being 10 to 30% by weight, based on the organic solvent.
  • esters of lower fatty acids with lower alcohols are preferred.
  • Butyl acetate proved to be particularly suitable.
  • Soaps suitable for the purposes of the invention are the sodium or potassium salts of saturated and unsaturated higher fatty acids, resin acids, rosin and naphthenic acids, which are commercially available as solid or semi-solid mixtures.
  • the potassium salts of higher fatty acids, the so-called soft soaps or potassium soaps have proven to be particularly suitable. Their proportion is significantly higher than is necessary only for the emulsification of the organic solvent and is about 10 to 30%, in particular 15 to 25% by weight of the amount of the organic solvent.
  • a mixture which has been found to be very suitable for removing epoxy resins from plates or tiles has been obtained by diluting a mixture of 100 liters of butyl acetate and 20 kg of soft soap with 500 liters of cold water.
  • the product thus produced can be filled into canisters and is ready for use in this form.
  • epoxy resins can be removed easily and effectively without any residues and thus free of fog. It can also be used to remove spots that were discovered afterwards. This removal of any residues of epoxy grout is achieved in a much shorter time than with the previously known methods. The time saved compared to the conventional way of working is more than 50%.
