Изобретение относитс к области литейного производства, в частности к составам разделительных покрытий дл модельной оснастки .FIELD OF THE INVENTION The invention relates to the field of foundry, in particular, to separation coating compositions for model tooling.
Известно покрытие дл модельной оснастки , состо щее из следующих компонентов, вес. %:A coating for model equipment is known, consisting of the following components, weight. %:
КеросинОсноваKeroseneBasic
Жирные кислоты30-20Fatty acids30-20
С целью улучщени качества и уменьшени брака форм и отливок в качестве жирной кислоты предлагаетс использовать олеиновую кислоту при следующем соотнощении компонентов , вес. %:In order to improve the quality and reduce the rejection of molds and castings, it is proposed to use oleic acid as a fatty acid at the following ratio of components, weight. %:
КеросинОсноваKeroseneBasic
Олеинова кислота 5-20Oleic acid 5-20
Вместо олеиновой кислоты могут быть использованы каприлова , миристинова , линолева , линоленова и другие жирные кислоты . Вместо керосина может быть использован уайт-спирит и другие углеводороды парафиноного р да.Instead of oleic acid, caprylov, myristic, linoleic, linolenic and other fatty acids can be used. White spirit and other paraffinone hydrocarbons can be used instead of kerosene.
Готов т покрытие путем растворени олеиновой кислоты или других в керосине. Полученное жидкое покрытие нанос т на поверхность модели с ломощью распыл ющих устройств до образовани равномерного тонкого сло . При однократном нанесении состава на модель возможно сн тие нескольких форм (до 5).A coating is prepared by dissolving oleic acid or others in kerosene. The resulting liquid coating is applied to the surface of the model with a spray of spray devices to form a uniform thin layer. With a single application of the composition to the model, it is possible to remove several forms (up to 5).
При использовании предлагаемого разделительного покрыти , значительно снижающего коэффициенты внешнего трени формовочной смеси о поверхность модельной оснастки, улучшаетс равномерность уплотнени форм и уменьшаетс прилипаемость смеси к модели. Применение покрыти позвол ет снизить брак форм ПО подрывам, брак отливок по подрывам формы, земл ным раковинам, раздутию, повысить весовую и размерную точность отливок.Using the proposed release coating, which significantly reduces the coefficients of the external friction of the molding mixture against the surface of the tooling, improves the uniformity of the molds and reduces the adhesion of the mixture to the model. The use of coating allows to reduce the defect of software forms for explosions, the loss of castings for mold explosions, earth shells, swelling, and to increase the weight and dimensional accuracy of castings.
