Изобретение относитс  к литейному производству .The invention relates to foundry.

Известны смеси дл  изготовлени  литейных форм и стержней, содержащие огнеупорный наполнитель, например .кварцевый песок, едкий натр, полимерное соединение типа стирола-полистирол и жидкое стекло.Mixtures for the manufacture of casting molds and cores are known, which contain a refractory filler, for example, quartz sand, caustic soda, a styrene-polystyrene polymer compound and liquid glass.

Однако эти смеси имеют недостаточную выживаемость.However, these mixtures have insufficient survival.

Цель изобретени  - улучшить выбиваемость смеси.The purpose of the invention is to improve the blendability of the mixture.

Это достигаетс  тем, что в состав смеси введен латекс СКС 65-ГП (ГОСТ 10564-63), при следующем соотношении ингредиентов, вес. %:This is achieved by the fact that the latex SKS 65-ГП (GOST 10564-63) is introduced into the mixture, with the following ratio of ingredients, weight. %:

Огнеупорный наполнительОсноваRefractory fillerBased

Едкий натр плотностью 1,2г/см. 1,0-1,2 Латекс (ГОСТ 10564-63)1,0-1,2Caustic soda with a density of 1.2 g / cm. 1.0-1.2 Latex (GOST 10564-63) 1.0-1.2

Жидкое стекло5,0-6,0Liquid glass5.0-6.0

Смесь готов т следуюш,им образом.The mixture is prepared in the following way.

В бегуны загружают огнеупорный наполнитель и едкий натр и перемешивают их 1 мин, лосле чего ввод т предварительно смешанные жидкое стекло и латекс и ведут перемешивание до получени  сырой прочности смеси 0,08-0,1 кг/см.Runners are charged with refractory filler and caustic soda and mixed for 1 minute, which is pre-mixed with liquid glass and latex and mixed until the raw mixture strength is 0.08-0.1 kg / cm.

В таблице приведены физико-механические свойства следующих составов смесейThe table shows the physico-mechanical properties of the following mixtures
