Description
Известные св зующие дл оболочковых форм и стержней содержат фенол-формальдегидные смолы, вл ющиес дорогими материалами .Known binders for shell forms and rods contain phenol-formaldehyde resins, which are expensive materials.
Описываемое св зующее значительно дещевле указанных. В качестве него предлагаетс феноло-лнгнин-альдегидна смола, вл юща с продуктом конденсапии щелочного сульфатного лигнина с фенолом и формальдегидом в присутствии катализатора-серной кислоты.The described binder is significantly more specified. It is proposed to use a phenol-lngnine-aldehyde resin, which is a condensation product of an alkaline sulfate lignin with phenol and formaldehyde in the presence of a sulfuric acid catalyst.
При измельчении она смешиваетс с 10% уротропина.When milled, it is mixed with 10% hexamine.
Щелочной сульфатный лигнин, используемый в качестве заменител фенола в фенол-альдегидной смоле, вл етс отходом сульфатно-целлюлозного производства.The alkaline sulphate lignin used as a substitute for phenol in the phenol-aldehyde resin is a waste from sulphate-pulp production.
Смесь на основе феноло-лигнин-альдегидной смолы имеет следующий состав (в весовых %):A mixture based on phenol-lignin-aldehyde resin has the following composition (in weight%):
кварцевого песка96,7-91,5;quartz sand 96,7-91,5;
увлажнител (керосин, фурфурол и др.)0,3- 1,2;humidifier (kerosene, furfural, etc.) 0.3-1.2;
феноло-лигнин-альдегидной смолы3-8%.phenol-lignin-aldehyde resin 3-8%.
Предмет изобретени Subject invention
Св зующее дл оболочковых форм и стержней, о т л и ч а ю HI; е е с тем, что, с целью экономии фенола и снижени стоимости, в качестве св зующего примен ют феноло-лигнин-альдегидную смолу, вл ющуюс продуктом конденсации щелочного сульфатного лигнина с фенолом и формальдегидом в присутствии катализатора - серной кислоты.Binder for shell molds and rods, HI; This is because, in order to save phenol and reduce the cost, a phenol-lignin-aldehyde resin is used as a binder, which is a condensation product of an alkaline sulfate lignin with phenol and formaldehyde in the presence of a catalyst — sulfuric acid.
