  • the formulated with lightweight fillers adhesive in their price of materials are also expensive.
  • tile adhesive For the installation of tile materials, however, such an adhesive is not suitable. Due to the high volume increase of more than 50% by volume, the stability of the tile adhesive required for the laying of tile materials is not achieved. So laid tiles would slip in the episode. It should also be noted that tile adhesives, once they have hardened, must have high intrinsic strengths in order to achieve the required bond strengths and bond tensile strengths with respect to the tile / substrate system. However, this is not possible with the high gas and volume fractions and the associated low intrinsic strengths of the mortars prepared and cured according to DE 10 2004 030 921.
  • tile adhesives of the present state of the art a maturation time of at most 5 minutes is required.

This is surprising inasmuch as starting from the prior art it was not to be assumed that the increase in volume of the adhesive according to the invention is already complete after 5 minutes of maturing time so that a laying of tile materials is possible. Furthermore, it was surprising that the tile adhesive produced and cured with this mixture has the required intrinsic strengths.

Abstract

L'invention concerne l'utilisation comme colle pour carrelage d'un mélange composé de a) un liant hydraulique à réaction alcaline, b) un éther de cellulose, c) un agent gonflant, d) une charge, caractérisée par le fait que l'agent gonflant c) est constitué de composés peroxo et/ou de percarbonates et/ou de poudre d'aluminium, et que le mélange de colle pour carrelage, après addition d'eau de gâchage, présente dans un délai de cinq minutes une augmentation maximale et stable de volume de 50 % en volume. Ce mélange, qui peut contenir en plus des quatre composants mentionnés d'autres additifs tels que, par exemple, des retardateurs, des agents antimousse et des poudres de polymères en dispersion, possède l'avantage que le produit gonflant utilisé, en 5 minutes, a presque totalement réagi et produit ainsi une augmentation du volume du mélange de colle pour carrelage d'un maximum de 50 % en volume. Après durcissement, le mélange présente une forte résistance propre, mais aussi une résistance composite et une caractéristique d'adhérence en traction suffisantes en ce qui concerne le système carrelage + support.
