Изобретение относитс  к литейному производству , а именно к составам дл  изготовлени  литейных форм и стержней.This invention relates to a foundry, namely, compositions for the manufacture of foundry molds and cores.

Известны смеси дл  изготовлени  литейных форм и стержней, содержащие огнеупорный наполнитель, гидролизованный раствор этилсиликата , водный раствор аммиака, графит и электродный бой, основой которого  вл етс  также графит.Mixtures for the manufacture of foundry molds and cores are known, containing a refractory filler, a hydrolyzed ethyl silicate solution, an aqueous ammonia solution, graphite, and electrode strikes, which is also based on graphite.

Однако такие смеси не обеспечивают достаточно чистой поверхности отливок, а вводимый в состав смеси электродный бой требует измельчени .However, such mixtures do not provide a sufficiently clean surface of the castings, and electrode strike introduced into the mixture requires grinding.

Цель изобретени  - уменьшение трудоемкости приготовлени  смеси и улучшение чистоты поверхности отливок.The purpose of the invention is to reduce the labor intensity of the mixture preparation and improve the cleanliness of the surface of the castings.

Эта цель достигаетс  тем, что электродный бой замен ют графитом, а компоненты смеси берут при следующем соотношении, вес. %: Огнеупорный наполнитель Основа Гидролизованный растворThis goal is achieved by replacing electrode strike with graphite, and the components of the mixture are taken in the following ratio, weight. %: Refractory filler Base Hydrolyzed solution

этилсиликата1,0-35,0ethyl silicate1.0-35.0

2-3%-ный водный раствор2-3% aqueous solution

аммиака0,1- 6,0ammonia0.1-6.0

Графит1,0-22,0Graphite1.0-22.0

В качестве огнеупорного наполнител  в составе смеси примен ют маршалит, пылевидный кварц, электрокорунд, циркон, дистенсиллиманит .Marshalite, powdered quartz, electrocorundum, zircon, and distensillimanite are used as a refractory filler in the mixture.

Дл  повышени  газопроницаемости смеси 50% этого огнеупорного наполнител  может быть заменено более крупнозернистым компонентом , например кварцевым, шамотным,To increase the gas permeability of the mixture, 50% of this refractory filler may be replaced by a more coarse-grained component, for example, quartz, chamotte,

оливковым или цирконовым песками.olive or zircon sand.

Дл  повышени  кроющей способности в состав смеси может быть введено 0,01 -1,0% поверхностно-активных веществ, например натриевых солей эфиров сульфо нтарной кислоты , синтамид-5, катамин, синтанолы, ОП-7 и т. д.To increase the coating ability, 0.01-1.0% of surfactants can be added to the mixture, for example, sodium salts of sulphatic acid esters, syntamide-5, catamin, syntanols, OP-7, etc.

Предмет изобретени Subject invention

Смесь дл  изготовлени  керамических литейных форм и стержней, преимущественно по посто нным модел м, включающа  огнеупорный наполнитель, гидролизованный раствор этилсиликата, водный раствор аммиака и графит , отличающа с  тем, что, с целью уменьшени  трудоемкости ее приготовлени  и улучшени  чистоты поверхности отливок, она содержит указанные компоненты при следующем соотнощении, вес. %:A mixture for the manufacture of ceramic molds and cores, mainly in permanent models, including a refractory filler, a hydrolyzed ethyl silicate solution, an aqueous ammonia solution and graphite, which in order to reduce the complexity of its preparation and improve the cleanliness of the surface of the castings, it contains these components in the following ratios, weight. %:
