Abstract
Przedmiotem zgłoszenia jest antykorozyjna kompozycja epoksydowo-poliuretanowa do wyrobu powłok lakierniczych na bazie mieszaniny izocyjanianów aromatycznych i cykloalifatycznych i sposób jej wytwarzania. Kompozycja epoksydowo-poliuretanowa według wynalazku charakteryzuje się tym, że zawiera żywicę epoksydową na bazie bisfenolu A w ilości od 8,0% do 30,0% wagowych, kwas rycynolowy w ilości od 11,5% do 38,0% wagowych, kwas benzoesowy w ilości od 0,5% do 7,0% wagowych, glikol poli(oksypropylenowy) i/lub oligowęglanodiol lub diol polibutadienowy w ilości od 5,0% do 50,0% wagowych, polimeryczny diizocyjanian 4,4'-metylenodifenylu (pMDI) w ilości od 9,0% do 36,0% wagowych, trimer heksametylenodiizocyjanianu (tHDI) w ilości od 1,0% do 11,0% wagowych, trimer izoforonodiizocyjanianu (tlPDI) w ilości od 1,0% do 10,0% wagowych, katalizator cynowy w ilości od 0,005% do 0,05% wagowych oraz napełniacze nieorganiczne w ilości od 5,0% do 30,0% wagowych. Sposób wytwarzania antykorozyjnej kompozycji epoksydowo-poliuretanowej według wynalazku polega na tym, że w temperaturze 90°C - 110°C prowadzi się proces reakcji żywicy epoksydowej, korzystnie jako żywicę epoksydową stosuje się żywice o liczbie epoksydowej od 0,41 do 0,54 mola grup epoksydowych na 100 g żywicy, z mieszaniną kwasów: rycynolowego i benzoesowego, korzystnie w stosunku molowym od 9:1 do 7:3, w ilości stechiometrycznej w stosunku do grup epoksydowych żywicy, w obecności katalizatora w postaci soli amoniowej, do momentu spadku liczby kwasowej poniżej wartości 5 mg KOH/g próbki, po czym dodaje poliol polieterowy w ilości od 10,0% do 50,0% wagowych i/lub oligowęglanodiol w ilości od 10,0% do 50,0% wagowych lub diol polibutadienowy w ilości od 10,0% do 50,0% wagowych oraz napełniacze nieorganiczne w ilości od 5,0% do 30,0% wagowych, poddaje się reakcji z mieszaniną diizocyjanianów aromatycznych i cykloalifatycznych, korzystnie w stosunku molowym od 9:1 do 7:3 w temperaturze otoczenia w obecności katalizatora cynowego, przy czym stosunek molowy grup hydroksylowych do grup izocyjanianowych wynosi 0,9 – 1,5.The subject of the application is an anti-corrosion epoxy-polyurethane composition for the production of paint coatings based on a mixture of aromatic and cycloaliphatic isocyanates and a method for its production. The epoxy-polyurethane composition according to the invention is characterized in that it contains an epoxy resin based on bisphenol A in an amount of 8.0% to 30.0% by weight, ricinoleic acid in an amount of 11.5% to 38.0% by weight, benzoic acid in an amount of 0.5% to 7.0% by weight, poly(oxypropylene) glycol and/or oligocarbonate diol or polybutadiene diol in an amount of 5.0% to 50.0% by weight, polymeric 4,4'-methylenediphenyl diisocyanate (pMDI) in an amount of 9.0% to 36.0% by weight, hexamethylenediisocyanate trimer (tHDI) in an amount of 1.0% to 11.0% by weight, isophoronediisocyanate trimer (tlPDI) in an amount of 1.0% to 10.0% by weight, a tin catalyst in an amount of 0.005% to 0.05% by weight and inorganic fillers in an amount of 5.0% to 30.0% by weight. The method of producing an anti-corrosion epoxy-polyurethane composition according to the invention consists in carrying out the reaction process of an epoxy resin at a temperature of 90°C - 110°C, preferably resins with an epoxy number of 0.41 to 0.54 moles of epoxy groups per 100 g of resin are used as the epoxy resin, with a mixture of ricinoleic and benzoic acids, preferably in a molar ratio of 9:1 to 7:3, in a stoichiometric amount in relation to the epoxy groups of the resin, in the presence of an ammonium salt catalyst, until the acid number drops below 5 mg KOH/g of sample, and then a polyether polyol is added in an amount of 10.0% to 50.0% by weight and/or an oligocarbonate diol in an amount of 10.0% to 50.0% by weight or a polybutadiene diol in an amount of 10.0% to 50.0% by weight and inorganic fillers in an amount of 5.0% to 30.0% by weight, are reacted with a mixture of aromatic and cycloaliphatic diisocyanates, preferably in a molar ratio of 9:1 to 7:3 at ambient temperature in the presence of a tin catalyst, the molar ratio of hydroxyl groups to isocyanate groups being 0.9 - 1.5.
