AI Technical Summary
Existing formulations using silane-terminated polyether and polysiloxane with mineral fillers are limited to a maximum thickness of 200 µm due to the formation of a crust on the surface, necessitating restarts when thickness exceeds this limit.
Replacing mineral fillers with plant-derived fillers containing cellulose, hemicellulose, and lignin, which react with silane functions to achieve coatings up to 2 cm thick by utilizing the OH functions of these components in the resin composition.
Enables coatings up to 2 cm thick with improved hardness and flexibility, overcoming the thickness limitations of traditional mineral filler-based compositions.
Abstract
Description
Title of the invention: Formulation for a floor covering and floor covering obtained from it
[0001] The present invention relates to a formulation for the production of a floor covering as well as a covering obtained from this formulation.
[0002] Floor coverings obtained by the process of: • mix a silane-terminated polyether-based resin composition and polysiloxane with a mineral filler such as kaolin or calcium carbonate; • spread the resulting mixture onto the floor to be coated, which may have been previously coated with a primer film; and • allow the layer thus formed to harden.
[0003] Such coatings cannot be obtained in a thickness exceeding 200 µm. Beyond this thickness, a crust forms on the surface of the applied layer, beneath which the layer remains in a liquid to pasty state. Under these conditions, the coating operations must be completely restarted, respecting the maximum thickness.
[0004] The applicant sought to overcome the drawback of limiting the possible thickness of a coating by using a resin composition based on silane-terminated polyether and polysiloxane, which is curable at room temperature. Its work led to the discovery that by replacing the mineral filler with a filler of plant origin, whose natural cellulose, hemicellulose, lignin, and moisture content makes it possible to obtain coatings up to 2 cm thick, or even more, for example, coatings from 2 mm to 2 cm thick.
[0005] The originality of this new formulation for floor coating lies in the behavior of the filler as a true component of the coating actively participating in its hardening due to the reaction of the OH functions of cellulose, hemicellulose and lignin and residual moisture with the silane functions of the resin.
[0006] The present invention therefore relates firstly to a formulation for a floor covering, characterized in that it comprises, per 100 parts by weight: A. 60 to 85 parts by weight of a moisture-curable resin composition based on at least one silane-terminated polyether (A1), at least one polysiloxane (A2), and at least one aminosilane co-crosslinking agent (A3); and B. 40 to 15 parts by weight of at least one hygroscopic powder of vegetable origin, containing cellulose, hemicellulose, lignin and residual moisture, and capable of reacting by the OH functions it contains with the silane functions of the constituents (Al), (A2) and (A3) of (A).
