Abstract
Изобретение относитс к литейному производству, в частности к сос тавам самотвердеющих противопригарных покрытий дл литейных форм и стержней , предназначенньпс преимущественно дл изготовлени стальных отливок. Цель изобретени - улучшение качества покрыти за счет повьпаени седиментаци- онной устойчивости состава, прочности на истирание и термостойкости, это достигаетс за счет того, что состав дл получени самотвердеющего противопригарного покрыти содержит в качестве отвердител жидкого стекла триацетин технический при следующем соотношении ингредиентов, мае. % : триацетин технический 2,1 - 2,4; жидкое стекло 37,5-41,0; цирконовьйг концентрат остальное. Такой состав самотвердеющего противопригарного покрыти позвол ет получать качественное литье за счет того, что состав с т желым наполнителем (цирконо- вый концентрат) имеет высокую седи- ментационную устойчивость, а само покрытие имеет большую прочность на истирание и высокую термостойкость. 2 табл. i (ЛThe invention relates to foundry, in particular, to compositions of self-hardening nonstick coatings for foundry molds and cores, which is intended primarily for the manufacture of steel castings. The purpose of the invention is to improve the quality of the coating by increasing the sedimentation stability of the composition, abrasion resistance and heat resistance, this is achieved due to the fact that the composition for preparing a self-hardening nonstick coating contains technical triacetin as a curing agent for liquid glass in the following ratio of ingredients, May. %: technical triacetin 2.1 - 2.4; liquid glass 37.5-41.0; zirconium concentrate the rest. Such a composition of a self-hardening nonstick coating allows to obtain high-quality casting due to the fact that the composition with a heavy filler (zirconium concentrate) has high sedimentation resistance, and the coating itself has greater abrasion resistance and high heat resistance. 2 tab. i (L
