Description
Известно, что дл получени электроизол ционных кле щих лаков класса нагревостойкостн «f нримен ютс различные полиэфирноэпоксидные композиции.It is known that various polyester epoxy compositions are used to produce electrical insulating adhesive varnishes of the heat resistance class f.
С целью расширени ассортимента электроизол ционных кле щих лаков класса нагревостойкости «F и использовани менее дефицитного сырь , нредлол ен способ получени полиэфирно-эноксидного электроизол ционного кле щего лака, состо щий в том, что полиэфирную глифталевую смолу, вход щую в состав полиэфирно-эноксидного лака, модифицируют синтетическими жирными кислотами фракции Ci7-Czu, адининовор кислотой и моноэтиланилином.In order to expand the range of electrically insulating adhesive varnishes of heat resistance class "F and using less scarce raw materials, a method of producing polyester-enoxide electrically insulating glue varnish, consisting in that polyester glyptal resin, which is part of polyester-enoxid varnish Synthetic fatty acid modifies fractions of Ci7-Czu, adinonovor acid and monoethylaniline.
Полученный лак может быть отвержден тетраэтоксисиланом.The resulting varnish can be cured with tetraethoxysilane.
Пример. Полиэфирную глифталевую смолу изготовл ют при температуре 180-190° до времени желатировани 1 г смолы 3-5 мин (при температуре 250°) и кислотного числа менее 30 мг по следующей рецептуре (в %):Example. Polyester glyphthalic resin is made at a temperature of 180-190 ° up to the time of gelatinization of 1 g of resin for 3-5 minutes (at a temperature of 250 °) and an acid number of less than 30 mg according to the following recipe (%):

Затем готов т лак, раствор полиэфирную смолу (35,7%) в органическом растворителе, представл ющем смесь толуола и ксилола в отношении 1 : 1 (46,4%) и добавл к раствору эпоксидную смолу (14,) и отвердитель тетраэтоксисилан (3,6Vo)Предмет изобр.етени Then a lacquer, a solution of polyester resin (35.7%) in an organic solvent, which is a mixture of toluene and xylene in a ratio of 1: 1 (46.4%), is prepared and added to the solution epoxy resin (14) and a hardener tetraethoxysilane (3 , 6Vo) The subject of the image of the shadow
