Изобретение относитс  к литейному производству , в частности к составам св зующих.This invention relates to foundry, in particular, to binder compositions.

Известно св зующее дл  литейного производства , представл ющее собой водный раствор поливинилового спирта. Однако стержни и формы, изготовленные из смесей на этом св зующем, имеют недостаточио высокую прочность и высокую гигроскопичиость.A foundry binder is known, which is an aqueous solution of polyvinyl alcohol. However, rods and molds made from mixtures on this binder have insufficient strength and high hygroscopicity.

с целью повышени  технологических и физико-механических свойств смеси, в состав известного св зующего введена полисилоксанова  жидкость при следуюн1ем соотнощеннп компонентов, (вес. ч.);in order to improve the technological and physicomechanical properties of the mixture, a polysiloxane fluid was introduced into the composition of a known binder at the next ratio of components, (weight h);

Водпы поливинилового спирта99-100 Полисилоксаиова  жидкость 0,1-0,5Polyvinyl alcohol vodpy 99-100 Polysiloxa liquid 0.1-0.5

В качестве полисилоксаиовой жидкости может быть использована полисилоксаиова  жидкость ПСЖ-5 и силиконовое масло ПФМС-4.PSG-5 polysiloxaic fluid and PFMS-4 silicone oil can be used as polysiloxaic fluid.

Готов т св зующее следующим образом.Prepare the binder as follows.

В 7,5-10%-11ый водиый раствор 1)юливинилового спирта ввод т полисплоксановую жидкость и перемещивают, например, в UGщалке при 1500-30GO об/мин в теченаю 1,5- 2 мин.In a 7.5-10% -11th aqueous solution of 1) ylivinyl alcohol, a polysloxane liquid is introduced and transferred, for example, in a UG pincer at 1500-30GO rpm for 1.5-2 minutes.

Примерные составы и свойства формовочных смесей на предложенном св зуюн1,ем по15 казаны в таблице.The approximate compositions and properties of the molding mixtures on the proposed binder 1, is indicated in the table below.
