Изобретение относитс  к способам получени  алкидных смол.This invention relates to methods for producing alkyd resins.

Известен способ получени  алкидной смолы нутем полиэтерификации фталевого ангидрида и пантаэритрита в присутствии синтетических жирных кислот (СЖК) с числом углеродных атомов 10-16. Однако лаки на основе полученной смолы образуют невысыхающие нри 18-20° С покрыти  и поэтому используютс  дл  эмалей гор чей сушки.A known method for producing an alkyd resin with chute polyesterification of phthalic anhydride and pantaerythritol in the presence of synthetic fatty acids (FFA) with a carbon number of 10-16. However, lacquers based on the obtained resin form non-drying nir 18-20 ° C coatings and therefore are used for hot-drying enamels.

Целью изобретени   вл етс  получение высыхающего при 18-20° С лака на основе алкидной смолы. Поставленна  нель достигаетс  тем, что в исходную смесь ввод т пирослизевую кислоту в количестве 13,1 -15,1% от веса исходной смеси.The aim of the invention is to obtain an alkyd resin-based lacquer drying at 18-20 ° C. The supplied nel is achieved by introducing pyrosyl acid in the amount of 13.1 -15.1% of the weight of the initial mixture.

Пример. В трехгорлую круглодонную колбу, снабженную механической мешалкой, термометром и ловущкой Дина-Старка с обратным холодильником дл  азеотронной отгонки воды, загружают 33 вес. ч. СЖК с числом атомов углерода 10-16, 13,1 вес. ч. пирослизевой кислоты, 27,84 вес. ч. фталевого ангидрида и 26,06 вес. ч. пентаэритрита. К смеси добавл ют 5% ксилола дл  осуществлени  азеотропной отгонки воды.Example. In a three-necked round-bottomed flask equipped with a mechanical stirrer, a thermometer, and a Dean-Stark trap with a reflux condenser for azeotronic distillation of water, load 33 wt. h. FLC with the number of carbon atoms 10-16, 13.1 weight. including pyroslic acid, 27.84 wt. including phthalic anhydride and 26.06 weight. h pentaerythritol. To the mixture is added 5% xylene to effect azeotropic distillation of water.

Процесс полиэтерификации провод т при 210-220° С до достижени  кислотного числа 20 мг КОП/Г в течение 7-8 час. Смолу уплотн ют до в зкости 50-60 сек по воронкеThe polyesterification process is carried out at 210-220 ° C until an acid number of 20 mg CPC / G is reached for 7-8 hours. The resin is compacted to a viscosity of 50-60 seconds through a funnel.

ВЗ-4 (50%-ный раствор в ксилоле). По окончании процесса синтеза смолу охлал дают до 150° С, раствор ют в кснлоле до в зкости 50 сек по ВЗ-4.VZ-4 (50% solution in xylene). At the end of the synthesis process, the resin is cooled to 150 ° C, dissolved in xnolol to a viscosity of 50 sec according to VZ-4.

Полученный лак с добавкой 6% сиккатива N° 63 при нанесении на металлическую подложку ирактическн высыхает при 18-20° С за 24 час и имеет при толщине покрыти  20- 22 мк следующие физико-механические свойства: твердость по ма тниковому прибору 0,43, изгиб по щкале гибкости 1 мм, удар 50 кгс. см, адгези  по методу решетчатого надреза 1.The resulting lacquer with the addition of 6% desiccant N ° 63 when applied on a metal substrate and dries at 18–20 ° C in 24 hours and has a physical and mechanical properties with a coating thickness of 20-22 μm: bending along the flexing plate of 1 mm, impact of 50 kgf. cm, adhesion by the method of lattice cut 1.
