Definitions

  • the present invention relates to an aqueous agent which can be used in the diluted state for cleaning and maintaining hard surfaces, in particular floors.
  • the selection of the agents is essentially determined by whether cleaning or preservation of the surface is to be achieved as a matter of priority.
  • those agents are used which produce more or less hard, resistant films.
  • the compositions usually contain, in emulsified form, waxes or film-forming polymers and crosslinking agents, as a rule heavy metal salts which, after drying, form self-glossy or polishable films on the treated surfaces. In this way, long-lasting preservation of the surfaces can be achieved, with strong mechanical stresses being well tolerated, depending on the quality of the film.
  • the invention relates to an aqueous floor cleaning agent in the form of a dispersion which contains surfactant, film-forming polymer and plasticizer and, if appropriate, further constituents customary in wiping care products and which is characterized in that it is both a high molecular weight polymer which has a pH of 12 is not water-soluble, and also contains a low molecular weight polymer which is water-soluble at a pH of 9.
  • the new agent has excellent cleaning properties and gives the floor surface a very uniform, clear shine after drying, which increases with repeated use. Nevertheless, the tendency towards re-soiling of the floors cleaned in this way is extraordinarily low. It is particularly noteworthy that the glossy film is obtained without the use of heavy metal salts as the crosslinking component.

Abstract

L'agent de nettoyage selon l'invention se présente sous la forme d'une dispersion aqueuse et contient un tensioactif, un polymère filmogène et un adoucissant. Ledit polymère filmogène est un mélange de deux polymères de différentes masses moléculaires. Le polymère ayant la masse moléculaire la plus élevée n'est pas soluble dans l'eau à un pH de 12, tandis que celui ayant la masse moléculaire la plus basse est soluble dans l'eau à un pH de 9. Après dilution, les agents selon l'invention sont utilisés pour le nettoyage et l'entretien de sols de tous types. Ces agents se caractérisent par une grande efficacité de nettoyage et par le fait qu'ils confèrent aux sols un brillant homogène et empêchent qu'ils se ressalissent facilement.
