Изобретение относитс к литейному производству, в частности к составам холоднотвердеющих смесей на основе карбамидного св зующего дл изготовлени литейных форм и стержней при литье, например, магниевых сплавов.The invention relates to a foundry, in particular, to compositions of cold-hardening urea-based binder mixtures for the manufacture of casting molds and cores during casting, for example, magnesium alloys.
Цель изобретени - улучшение качества форм и стержней за счет повышени их прочности и уменьшени осыпаемости .The purpose of the invention is to improve the quality of the molds and cores by increasing their strength and reducing flaking.
Сущность изобретени заключаетс в следующем.The essence of the invention is as follows.
Дл использовани карбамидной смолы служит смола технической марки ВК-1 .For the use of carbamide resin is a resin technical grade VK-1.
В качестве ортофосфорной кислоты используют технический продукт,разбавленный водой до плотности 1 ,05 - 1,30 г/см3.As an orthophosphoric acid, a technical product is used, diluted with water to a density of 1.05 to 1.30 g / cm3.
Шунгит - природньй минерал,отход горнорудной промышленности, представл ет собой твердый раствор внедрени углерода (10 - 35 мас.%) в кварце.Shungite is a natural mineral, a waste of the mining industry, is a solid solution introducing carbon (10 - 35 wt.%) In quartz.
Составы предлагаемых смесей приведены в табл,1.The compositions of the proposed mixtures are given in table. 1.
Смеси готовили в бегунах с вертикально расположенными катками.Врем перемешивани компонентов 3-5 мин. Прочность образцов при сжатии и осыпаемость провер ли после выдержки при комнатной температуре в течение 24 ч на стандартных приборах.The mixtures were prepared in runners with vertically located rollers. The components were mixed for 3-5 minutes. Compressive strength and crushability of the specimens were tested after exposure at room temperature for 24 hours on standard instruments.
Физико-механические свойства предлагаемых смесей приведены в табл. 2.Physico-mechanical properties of the proposed mixtures are given in table. 2
