Description
Известны св зующие дл формовочных и стержневых смесей, в состав которых входит касторовое масло и канифоль.Binders are known for molding and core mixtures, which include castor oil and rosin.
Предлагаемый способ св зывани формовочных и стержневых масс также использует касторовое масло и канифоль как св зующее, но отличаетс тем, что последние ввод тс в земли в виде водной эмульсии, полученной частичным омылением смеси касторового масла и канифоли.The proposed method of bonding molding and core masses also uses castor oil and rosin as a binder, but differs in that the latter are introduced into the earth in the form of an aqueous emulsion obtained by partially saponifying the mixture of castor oil and rosin.
Св зующее готовитс следующим образом. Касторовое маСло препарируетс при температуре 270-290° до в зкости по воронке НИЛКа - 25 минут.The binder is prepared as follows. The castor oil is prepared at a temperature of 270-290 ° C to a viscosity according to the NILK funnel - 25 minutes.
Затем к маслу добавл етс 30 вес. ч., по отношению к препарированному маслу, канифоли, и состав тщательно перемешиваетс .Then, 30 wt. in relation to the prepared oil, rosin, and the composition is thoroughly mixed.
По остывании до 130 добавл етс при тщательном перемешиванииUpon cooling to 130, it is added with thorough mixing.
3%- аммиачна вода в количестве 20%, затем добавл етс чиста вода, и состав вновь перемещиваетс .3% ammonia water in an amount of 20%, then pure water is added, and the composition is again moved.
Общее содержание влаги не должно быть более 45%.The total moisture content should not be more than 45%.
Предлагаемое св зующее при испытании дало сопротивление на разрыв в 8 KZjCMl в сухих образцах при содержании 2% св зующего .The proposed binder under test gave a tensile strength of 8 KZjCMl in dry samples with a binder content of 2%.
Предмет изобретени .The subject matter of the invention.
Способ св зывани формовочных и стержневых смесей с использованием касторового масла и канифоли, отличающийс тем, что землю смещивают с водной эмульсией касторового масла и канифоли, полученной частичным омылением смеси указанных ингредиентов.A method of bonding molding and core mixtures using castor oil and rosin, wherein the earth is biased with an aqueous emulsion of castor oil and rosin, obtained by partially saponifying the mixture of the above ingredients.
