Description
В литейном производстве при изготовлекии форм и стержней примен ютс так называемые крепители , которые вл ютс св зуюншми дл формовочных материалов и после сушки или отвердени обеспечивают получение литейных форм и стержней с необходимыми технологическими свойствами.In the foundry industry, molds and cores are made using so-called binder, which are bonded to molding materials, and after drying or curing, they produce casting molds and cores with the necessary technological properties.
Известен р д крепителей на различных масл ных и безмасл ных основах.A number of fasteners are known on various oil and non-oil bases.
Особенностью описываемого св зующего вл етс то, что с целью удешевлени последнего, в его состав ввод т: 40-60% маточного раствора, вл ющегос отходом от производства многоатомного спирта пентаэритрита, 30-20% солейThe peculiarity of the described binder is that in order to reduce the cost of the latter, 40-60% stock solution is introduced into its composition, which is a waste from the production of pentaerythritol polyhydric alcohol, 30-20% salts
смол ных и ;кирных кислот и 30- 20% раствор 1ггел , например, уайтспирита .resin and acid acids and 30–20% solution of 1ggel, for example, white spirit.
Предлагас.мый безмасл ный крепитель получают путем обработки предварительно упаренного маточного раствора производства многоатомного синрта-нентаэритрита- со.ч ми смол ных, жирных или нафтеновых кислот. В качестве последних могут быть применены, например , кальцевые п другие соли окисленного петралатума и кальцевые н другие соли таллового масла. В качестве растворител примен етс уайт-спирит.Our oil-free binder is obtained by treating a pre-stripped mother liquor of the production of polyatomic syn-nentaerythritol with resin, fatty, or naphthenic acids. As the latter, for example, calcic n other salts of oxidized petrolatum and calcinic n other tall oil salts can be used. White spirit is used as a solvent.
Литейные формы и стержни, нзготовленные с предлагаемым св зующим , по физико-механическим № 109815 свойствам и технологическим паказател м обеспечивают хорошую поверхностную прочность при высокой удельной прочности. Предмет изобретени Св зующее дл изготовлени литейных форм и стержней, отличающеес тем, что, с целью удешевлени , в его состав ввод т: маточного раствора, вл ющегос отходом от производства многоатомного спирта пентаэритрита, 40 - 60%, солей смол ных и жирных кислот 30 - 20% и растворител (например уайт-спирита) 30- 20%.Molds and cores prepared with the proposed binder, according to the physicomechanical property No. 109815 and technological factors, provide good surface strength with high specific strength. BACKGROUND OF THE INVENTION A binder for the manufacture of casting molds and cores, characterized in that, in order to reduce the cost, it consists of: a stock solution that is a waste from the production of pentaerythritol polyhydric alcohol, 40-60%, salts of resin and fatty acids - 20% and solvent (for example white spirit) 30-20%.
