| titleOfInvention | WATERPROOF POLYURETHANE RESINS STABILIZED ELECTROESTHRICALLY, PROCEDURE FOR OBTAINING AND EMPLOYMENT. |
| abstract | Aqueous dispersions of polyurethane, anionically modified, stabilized in an electro-sterile manner, which can be obtained by means of a) the preparation of a hydrophilic and solvent-free macromonomer (A) (ii) with a monomodal distribution of molecular weights, in that a1) between 50 and 100 parts by weight of an alkylpolyalkylene glycol and / or an arylpolyalkylene glycol, hydrophilic, (A) (i) are reacted with a group of primary and / or secondary and / or tertiary hydroxyl type, which is reactive against isocyanate type groups and with a molecular weight between 250 and 5,000 Daltons, with 1 to 100 parts by weight of a polyisocyanate (B) (i), which is constituted by at least one diisocyanate, a polyisocyanate , a polyisocyanate derivative or by polyisocyanate homologs, with two or several aliphatic or aromatic isocyanate (cyclo) groups, with an identical or different reactivity, if necessary in the presence of a catalyst a2) is reacted ar the product, which comes from step a1), completely with 0.5 to 200 parts by weight of a compound (C) with two or several amino-type groups and / or hydroxyl-type groups, primary or secondary, which they are reactive against isocyanate type groups, and with a molecular weight between 50 and 500 Daltons, the reaction conditions and the selectivity of component (C) being chosen in such a way that only a reactive group of component (C) reacts ) with the group (s) of the free isocyanate type (s) of the pre-addition product, as well as b) by means of obtaining the polyurethane dispersion, reacting b1) between 2 and 50 parts by weight of the macromonomer (A) (ii) hydrophilic and solvent-free, with a monomodal distribution of molecular weights, with two or several hydroxyl groups, which are reactive against isocyanate groups and with a molecular weight between 500 and 5,500 Daltons, with 25 to 250 parts by weight of a polyisocyanate (B) component (ii), which is constituted by at least one polyisocyanate, a polyisocyanate derivative or by polyisocyanate homologs, with two or several aliphatic or aromatic (cyclo) isocyanate-type groups , if necessary, with a contribution of 0 to 50 parts by weight of a solvent component (C) and, if necessary, in the presence of a catalyst, b2) the polyurethane pre-addition product is reacted, which comes from the step b1), with 50 to 100 parts by weight of a polymer polyol (A) (iii) with two or several hydroxyl type groups, which are reactive against isocyanate type groups, and with a molecular weight between 500 and 5,000 Daltons and, if appropriate, with 0.5 to 10 parts by weight of a polyol component (A) (vi), of low molecular weight, with 2 or with several hydroxyl groups and with a molecular weight between 50 and 499 Daltons, if necessary in the presence of a catalyst, b3) the product is reacted pre-addition to polyurethane, which comes from step b2), with 2 to 20 parts by weight of a polyol component (A) (v), of low molecular weight, and modified anioincaly, with one, with two or with several hydroxyl groups, which are reactive against isocyanate groups, and with one or more inert groups of carboxylic acid and / or sulfonic acid, which can be partially or totally transformed with the aid of bases in carboxylate groups either in sulfonate groups or in the form of carboxylate groups and / or sulfonate groups, and with a molecular weight between 100 and 1,000 Daltons, if necessary in the presence of a catalyst, b4) the polyurethane prepolymer, which precedes stage b3), before or during water dispersion, to carry out partial or complete neutralization of the acid groups, with 2 to 20 parts by weight of a neutralization component (E), b5) the polyurethane prepolymer, if necessary neutralized (in part), which comes from step b4), it is dispersed in 50 to 1,500 parts by weight of water, which, if necessary, also contain from 0 to 100 parts by weight of a formulation component (F) and, finally b6) the neutralized polyurethane prepolymer dispersion (partly, which comes from step b5) is reacted, with 3 to 60 parts by weight of a component for the extension of the chains (G) as well as below , or simultaneously, with 0 to 30 parts by weight of a component for stopping the chains (H). |
