Description
Vynález sa týká lakovej kompozície pre povrchová úpravu usní, zvlášť prírodných, pozostávajúce]' z nitrocelulózy, polyměrneho zmákčovadla, látky znižujúcej povrchové napatie a zmesi organických rozpúšťadiel.The invention relates to a lacquer composition for the treatment of leather, in particular natural leather, consisting of nitrocellulose, a polymeric wetting agent, a surface tension reducing agent and a mixture of organic solvents.
Lakové kompozície obsahujúce nitrocelulózu sú bežne používané ako ochranné nánosy pri povrchovej úpravě usní. Je známa filmotvorná apretúra tvořená nitrocelulózou a polymetanovým produktom v pomere 100 :140 hmot. dielov, namákčená nízkomolekulovými zmakčovadlami typu dibutylftalátu a dioktylftalátu alebo dibutyladipátu a diaktyladipátu. Známa je nátěrová kompozícia na báze nitrocelulózou modifikovaného uretánu, ktorá sa používá pre konečnú úpravu usne. Iná známa laková kompozícia obsahuje nitrocelulózu, polyuretán terminovaný izokyanátovými skupinami uvolněnými reakciou polyizokyanátu s alifatickým polyolom. Ďalej je známy lak na báze nitrocelulózy, ktorý obsahuje v rozpúšťadlovom systéme metyléntetrahydropyrán. DQležitým ingradientom v uvedených lakových kompozíciach sú plastifikátory. Okrem už spomínaných ftalátových sú známe plastifikátory, ako sú ricínový a vařený lanový olej. Nevýhodou týchto typov je tendencia migrovat do usne počas skladovania, čím sa povrchový nános stává křehkým a znižuje sa odolnost voči oderu. Niektoré typy lakov si vyžadujú špeciálny rozpúšťadlový systém obmedzene miešatetný s rozpúšťadlami pre nitrocelulózu, a tým je laková kompozícia málo stabílná. Hodnoty pevnosti a ťažnosti sú radové odlišené a pri jednotlivých typoch je nevýhodou, že převláda vždy jedna z nich.Nitrocellulose-containing lacquer compositions are commonly used as protective coatings in the coating of leather. A film-forming finish consisting of nitrocellulose and a polymethane product in a ratio of 100: 140 wt. parts soaked with low molecular weight plasticizers of dibutyl phthalate and dioctyl phthalate type or dibutyl adipate and diactyl adipate. Known is a coating composition based on nitrocellulose-modified urethane, which is used for finishing leather. Another known lacquer composition comprises nitrocellulose, a polyurethane terminated by isocyanate groups released by the reaction of the polyisocyanate with an aliphatic polyol. Furthermore, a nitrocellulose lacquer is known which contains methylene tetrahydropyran in a solvent system. An important inhibitor of these coating compositions are plasticizers. In addition to the phthalate salts mentioned above, plasticizers such as castor oil and boiled rope oil are known. A disadvantage of these types is the tendency to migrate into the leather during storage, thereby making the surface coating brittle and reducing the abrasion resistance. Some types of lacquers require a special solvent system that is limited to the miscibility with nitrocellulose solvents, and thus the lacquer composition is poorly stable. The values of strength and ductility are in-line different and for each type it is disadvantage that one of them prevails.
Uvedené nedostatky odstraňuje laková kompozícia, ktorej podstata spočívá v tom, že obsahuje, vztahované na celkové množstvo lakovej kompozície, 7 až 10 % hmot. nitrocelulózy, 3 až 7 % hmot. nasýteného lineárneho polyesteru na báze kyseliny adipovej a dietylénglykolu terminovaného hydroxylovými a karboxylovými skupinami, s číslom kyslosti 43 až 60 mg KOH/g, o viskozite 0,15 až 20 Pa . s pri 25 QC, 0,5 až 2,5 % hmot. neiónového produktu znižujúceho povrchové napátie připraveného polyadíciou etylénoxidu s ricínovým olejom, s povrchovým napátím 35 až 38 nM/m, jódovým číslom 22 až 28, rozpuštěných v zmesi organických rozpúšťadiel.These drawbacks are overcome by a lacquer composition comprising 7 to 10% by weight, based on the total amount of the lacquer composition. % nitrocellulose, 3 to 7 wt. of a saturated linear polyester based on adipic acid and diethylene glycol terminated with hydroxyl and carboxyl groups, with an acid number of 43 to 60 mg KOH / g, with a viscosity of 0.15 to 20 Pa. s at 25? C, 0.5 to 2.5% by weight. a nonionic surface tension reducing product prepared by polyaddition of ethylene oxide with castor oil, with a surface tension of 35 to 38 nM / m, an iodine number of 22 to 28, dissolved in a mixture of organic solvents.
Technický účinok vynálezu spočívá v tom, že sa výhodné optimalizujú hodnoty pevnosti a ťažnosti nánosu laku vytvořeného striekaním na povrchu usne. Laková kompozícia zabezpečuje optimálnu flexibilitu, odolnost voči stieraniu za sucha aj za mokra a odolnost voči opakovanému ohybu. Laková kompozícia je stabílná a pri znížených teplotách, je 1'ahko rieditelná a aplikovatelná běžnými nanášacími zariadeniaml. Jej příprava je jednoduchá a nevyžaduje si speciálně zariadenia ani viacstupňové technologie.The technical effect of the invention is to optimize the strength and ductility values of the spray coating on the leather surface. The varnish composition provides optimum flexibility, resistance to dry and wet wiping and repeated bending resistance. The coating composition is stable and at reduced temperatures, is readily dilutable and can be applied by conventional coating equipment. Its preparation is simple and does not require special equipment or multi-stage technology.
