(57) Abstract:Usage: to obtain a binder based on Uralkalij resins intended for the surface treatment and finishing of various materials on a paper basis. Essence: vegetable oil or fatty acid modified with polyol, then the product modification process dicarboxylic acid or its anhydride and ester of rosin acid number 120-130 mg/COM, and so pl. 130-145oWith the amount of 5-30 wt.% by weight carboxyl-containing oligoarticular, and then di - or polyisocyanate in the environment of an organic solvent. table 2. The invention relates to the technology of binders based Uralkalij products intended for use as paints and other coatings for the surface treatment and finishing of various materials based on paper (decorative, label paper, Wallpaper, securities and so on).A method of obtaining a binder for various coatings, the interaction of oligoester modified castor oil with the isocyanate component in the presence of a mixture of N, N' substituted aliphatic amine with an aliphatic alcohol WITH4-C9when bootslove Uralkali resin, providing coating compositions for paper with their use of indicators on the speed of drying, hardness and protective properties, not gives them the print properties.Also known is a method of obtaining a binder for paints paper, including the interaction of the oil, preferably coconut, lead oxide and trimethylolpropane with stirring, cooling the obtained product and the processing of the received oligoarticular polyisocyanate, mainly isophorondiisocyanate, in the presence of dibutyltindilaurate tin in the environment of an organic solvent, such as ethanol 
The obtained binder is a non-drying walkydog resin used in the manufacture of printing inks for paper with high printability and improving wettability of the pigment, which in turn contributes to the increase of the degree of gloss and resistance to abrasion of printed materials.However, the use of such a binder for coating compositions for paper leads to insufficient chemical resistance of coatings.The closest analogue of the invention is a method for preparing a binder for paper coating by modifying what LOTOS or its anhydride and manifastation the treatment product obtained carboxyl-containing oligoarticular the isocyanate in the medium of organic solvent 
According to the method as infolistidega product using a modified rosin phenolic resin.The obtained binder is a product of the interaction of plant oils, such as soybean, with a dicarboxylic acid, for example, isophthalic, modified rosin phenolic resin and isocyanate, for example, colordistance.However, with a sufficiently high printing qualities, the composition of the paint coating obtained using a prepared binder, does not provide high speed drying of coatings on paper and to provide a relatively quick time full consolidation.The aim of the invention is to improve the printing properties of paper and its operating characteristics by increasing the speed of drying of coatings on paper and reduce the time of their full consolidation while maintaining high chemical resistance of the coating.This is achieved in that in a method of producing a binder for paper coating by modifying polyol vegetable oil or fatty acid, the interaction of product modification with a dicarboxylic acid or its anhydride and manifolding the anatomist in the environment of an organic solvent, as infolistidega product use ester of rosin acid value of 120-150 mg KOH/g and a melting point 130-145oWith the amount of 5-30% by weight of carboxyl-containing oligoarticular.At the same time as the polyol (polyhydric alcohol) use pentaerythritol, dipentaerythritol, trimethylolpropane or mixtures thereof. As vegetable oils used linseed, soybean, cottonseed, sunflower, and fatty acids of tall oil; as dicarboxylic acids and their anhydrides, use of phthalic, isophthalic, tetraisopropyl. As di - or MDI use of 2,4-toluylenediisocyanate, mixture of isomers 2,4 - and 2,6-toluylene diisocyanate and/or a ratio of 80/20 and 65/35 respectively, 4,4-diphenylmethanediisocyanate, polyphenylisocyanate. As infolistidega product use rosin esters with a melting point 130 - 145oC and an acid number of 120-150 mg KOH brand RC-12 (the product of the interaction of rosin, fumaric acid and pentaerythritol) and brand RC-15 (product of the interaction of rosin, maleinovogo anhydride and pentaerythritol).Offer oracene binder modified manifastation product, get sladkovo soda in a stream of carbon dioxide to 245-265oC. Then, at this temperature, load polyol and maintain the reaction mass until complete solubility product of the interesterification in ethanol at a ratio of 1:5. Then the reaction mass is cooled to 150-180oSince, at this temperature, enter RC-15 and incubated for 1 h then the reaction mass is then cooled to 130oTo download phthalic anhydride and withstand received oligoarticular, modified RC-15, up to an acid number of 55-65 mg KOH/gIn the case of fatty acids of vegetable oils stage interesterification is excluded. In this case, the receiving oligoarticular is the interaction of fatty acids with an excess of polyol with a subsequent interaction with a dicarboxylic acid or its anhydride and the introduction of the ester of rosin.To remove traces of water hold the azeotropic distillation of traces of water with toluene at 80-110oAnd vacuum 600-650 mm RT.article.Thus obtained carboxyl-containing oligoarticular dissolved in hydrocarbon solvents (white spirit, undecane or their mixtures), heated to 75 - 80oWith, then download isocyanate within 2-6 hours.The temperature of the reaction mass the side at the same temperature until the content of isocyanate groups of no more than 0.5% then enter N, N'- substituted aliphatic amine to stabilize the resin.Thus obtained Uralkaliy resin, modified ester of rosin (RC-15) has a molecular weight of 2,000-2,500, the content of carboxyl groups 50-65, the content of the adduct of rosin 5-30% To determine the properties of time fixing, speed drying time fixing and chemical resistance paper prepared printing ink in the traditional way.In a solution of binder (Uralkali resin) is injected pigments, fillers, driers, additives and solvents. The mixture is stirred first at dissolvere, and then fray on a three-roll kraskoterke drive to the milling degree of 10-15 μm.In table. 1 presents examples of the method of obtaining a binding Uralkali resins, including their composition, test cases (5 and 6) and the prototype. In table. 2 presents the formulations of paints and data on the properties of coatings based on Uralkalij resins.As a binder take the reaction product of a modified soybean oil alkyd resin based on isophthalic acid and pentaerythritol, optionally modified rosin-maleic resin with a diisocyanate (see example 4 of U.S. patent N 4148767).From Taba paper, in particular, in printing inks, paper provides improved printing properties and other operational characteristics by reducing the time of fixing the ink on the paper, accelerate the complete drying of the paint, but also enhance chemical resistance. The way to obtain a binder for paper coating by modifying polyol vegetable oil or fatty acid, the interaction of product modification with a dicarboxylic acid or its anhydride and manifastation product and subsequent processing of the obtained carboxyl-containing oligoarticular di - or polyisocyanate in the environment of an organic solvent, characterized in that as infolistidega product use ester of rosin with an acid number of 120 to 150 mgKOH/g and a melting point 130 - 145oWith the amount of 5 to 30 wt. carboxyl-containing oligoarticular.
