Description
Изобретение относитс к производству св зующих материалов.This invention relates to the manufacture of bonding materials.
Известны способы получени св зующих растворением кубовых остатков производства синтетических жирных кислот (СЖК) в уайтспирите и в бензиновых фракци х углеводородов .Methods are known for producing binders by dissolving bottoms from the production of synthetic fatty acids (FFA) in white spirit and in gasoline fractions of hydrocarbons.
По предлагаемому способу с целью стабилизации и улучшени качества кубовые остатки св зующего от дистилл ции синтетических жирных кислот обрабатывают водой с температурой 80-90°С и последующей сушкой при 90-150 С.In the proposed method, in order to stabilize and improve the quality, the bottoms of the binder from the distillation of synthetic fatty acids are treated with water at a temperature of 80-90 ° C and then dried at 90-150 ° C.
Способ заключаетс в следующем.The method is as follows.
150 г кубового остатка с кислотным числом 40; 54 и Ь7 мг/КОН/г подвергают трехкратной обработке водой в соотношении i : 1 при температуре 80-90°С и с последующим отделением воды отстоем при и кубового остатка нагревом до 150°С.150 g VAT residue with an acid number of 40; 54 and 7 mg / KOH / g are subjected to three-fold treatment with water in the ratio i: 1 at a temperature of 80-90 ° C and with subsequent separation of water by sludge at the bottom residue by heating to 150 ° C.
На основе исходных и обработанных кубовых остатков готов т св зующее по известной технологии УСК-1.Based on the original and processed bottoms, a binder is prepared according to the known USK-1 technology.
Качественные показател) св зующих приведены в таблице.Qualitative indicators of the binders are given in the table.
Предмет изобретени Способ получени св зующего дл литейных форм и стержней на основе кубовых остатков от дистилл ции синтетических жирных кислот путем растворени последних в 15 растворителе, отличающийс тем, что, с целью стабилизации и улучшени качества св зующего, кубовые остатки от дистилл ции синтетических жирных кислот обрабатывают водой с температурой 80-90 С и последую;; ,ей сушкой при 90-150°С.The subject of the invention. A method for producing a binder for casting molds and cores based on bottoms from the distillation of synthetic fatty acids by dissolving the latter in 15 solvents, characterized in that, to stabilize and improve the quality of the binder, bottoms from the distillation of synthetic fatty acids treated with water with a temperature of 80-90 ° C and thereafter ;; , drying it at 90-150 ° C.
