Abstract

Изобретение относится к способу изготовления литейных стержней и литейных форм для литейной промышленности, в котором получают сыпучий огнеупорный формовочный материал; на сыпучий огнеупорный формовочный материал наносят кислоту, получая таким образом огнеупорный формовочный материал с покрытием из кислоты; на огнеупорный формовочный материал с покрытием из кислоты наносят кислотоотверждаемое связующее, получая таким образом огнеупорный формовочный материал с покрытием из связующего; из огнеупорного формовочного материала с покрытием из связующего формуют формованное изделие и отверждают формованное изделие; при этом кислота представляет собой смесь метансульфоновой кислоты и по меньшей мере одной дополнительной кислоты, не содержащей серу. Изобретение также относится к композиции формовочного материала, используемой в данном способе. С использованием данного способа или данной композиции можно изготовить литейные формы, которые в процессе литья демонстрируют сниженную эмиссию вредных для здоровья соединений.
