Description

В насто щее врем  дл  эмалировани  электрических нроводоз используют электроизол ционные лаки на основе фенольных, меламинных и эноксидных смол, модифицированных алкидами.Nowadays, electrically insulating varnishes based on phenolic, melamine and enoxide resins modified with alcides are used to enamel electric nanowires.

Предложено в состав лахов дл  нокрыти  медных и других ироуюдов круглого и пр моугольного сечени  в качестве св зуюп1,сго вводить высокомолекул рную эпоксидную смо.ту, модифицированную блокированными днизоцианатами и себациновым полиэфиром.It has been proposed as a bond for copper and other round and rectangular sections as a bond, to introduce high molecular weight epoxy resin modified with blocked dicylocyanates and sebacin polyester.

Эта особенность дает возможность получать лаки, обладающие высокими электроизол ционными свойствами, водостойкостью, химической стойкостью, эластичностью и термостойкостью при тсмнературе .This feature makes it possible to obtain varnishes with high electrical insulating properties, water resistance, chemical resistance, elasticity, and heat resistance in the case of a chemical seal.

Получают лак следующим образом. Высокомолекул рную эпоксидную смолу и полиэфир на основе себациновой кислоты, диэтиленгликол  и глицерина раствор ют при нагревании в крезоле. К полученному раствору добавл ют монофенилдиизоцианат или фе П1Лэтилеидиизоциапат и нагревают при температуре 70-80 до полного растворени  изоциаиата . В результате получают ирозрачные, стабильные при храпении лаки с в зкостью раствора в крезоле через 20-25 мин около (по вискозиметру ВЗ-4 при 20С).Get varnish as follows. High molecular weight epoxy resin and polyether based on sebacic acid, diethylene glycol and glycerin are dissolved by heating in cresol. To the resulting solution is added monophenyl diisocyanate or Fe P1Letyleidiisozapat and heated at a temperature of 70-80 until the isocyanate is completely dissolved. As a result, lacquers that are stable when snoring with a solution viscosity in cresol are obtained in about 20-25 minutes (using the OZ-4 viscometer at 20 ° C).
