METHOD FOR APPLICATION OF COATINGS, GLUING AND CONNECTION OF MINERAL SURFACES Russian patent published in 2014 - IPC C09D175/04 C09J175/04 C04B41/48 C08G18/10 C08G18/12 C08G18/28 C08G18/38 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of applying coatings for gluing or connection of surfaces of mineral materials by means of synthetic resin, preferably the 2-component synthetic resin. The invention is used for the reinforcement of slopes, first of all, coastal slopes to regulate moving water flows. The method for applying coatings for gluing or connection of the surfaces of mineral materials by means of the 2-component synthetic resin is realised by the application of the said synthetic resin on a surface or by connection of the surfaces of mineral materials by means of the synthetic resin and solidification of the said synthetic resin, containing from 0.01 to 10 wt % of one or several hydroxy- or alcoxyaminosilane compounds of general formula

in which substitutents have the following values: X is independently on each other OH, CH₃, O[CH₂]_pCH₃; Y [CH₂]_t, [CH₂]_rNH[CH₂]_s; R, R' H, [CH₂]_tCH₃; t 0-10; n 1-3; p 0-5; m 4-n; r, s is independently on each other 1-10. The said synthetic resin represents a hydrophobic polyurethane resin, obtained by mixing a polyisocyanate component (i) with a polyol component (ii), with the polyol component (ii) containing one or several synthetic fatty polyols, obtained from vegetable oils and fats, with an alkoxyaminosilane compound being contained in the polyol component (ii).

EFFECT: invention makes it possible to increase the strength of the composition connection to the surface of mineral materials.
