Liquid fluorine-containing composition for surface treatment of mineral and non-mineral substrates

摘要

The invention relates to liquid fluorine-containing compositions which have a fluorine content, based on the solid resin, of approximately 5 to 75 % by weight, for the permanent treatment of porous and non-porous substrates. The inventive compositions are obtainable by a) producing a perfluoroalkyl component (A), b) dissolving approximately 5 to 100 parts by weight of the perfluoroalkyl component (A) obtained in step a) prior, during or after reaction in approximately 0 to 100 parts by weight of a solvent component (K), cSUB1/SUB) optionally (partially) hydrolyzing or silanolizing the perfluoroalkyl component (A) obtained in steps a) or b) in the presence of approximately 0 to 50 parts by weight of an aminoalkylalkoxysilane component (E)(i) and/or aminosilane component (E)(ii) with approximately 1 to 50 parts by weight of water, cSUB2/SUB) quaternizing the aminofunctional adduct with approximately 5 to 50 parts by weight of an acid component (L) (direct neutralization), cSUB3/SUB) optionally removing the released alcohol and/or the solvent component (K), dSUB1/SUB) dissolving the reaction product obtained in step c) subsequently or simultaneously in approximately 50 to 1000 parts by weight of water and oligomerizing it, dSUB2/SUB) optionally removing the released alcohol and/or the solvent component (K), e) whereby optionally during or after steps a) and/or b) and/or c) and/or d) approximately 0 to 50 parts by weight of a formulation component (M) can be added in any manner and/or approximately 0 to 50 parts by weight of a functionalization component (N) are added and/or co-reacted. The invention makes available vapor-permeable coating systems for permanently treating the surfaces of mineral and non-mineral substrates with oil, water and dirt-repellent surface agents or for modifying them. The inventive liquid fluorine-containing compositions have substantially improved properties of application at the same or lower fluorine content as conventional products.
