Изобретение относитс  к керамическим св зкам дл  абразивного инструмента.The invention relates to ceramic binder for an abrasive tool.

Известна керамическа  св зка дл  изготовлени  шлифовального инструмента на основе двуокиси кремни .Ceramic bonding for the manufacture of a silicon dioxide grinding tool.

Однако эта св зка обладает пониженной адгезией к абразивному зерну.However, this bond has reduced adhesion to the abrasive grain.

Целью изобретени   вл етс  повышение адгезии св зки к зернам абразива.The aim of the invention is to increase the adhesion of the bond to the abrasive grains.

Дл  этого в состав св зки введена окись лити , а компоненты вз ты в следующем соотношении , вес.%:For this purpose, lithium oxide was added to the binder, and the components were taken in the following ratio, wt.%:

SiOa61-69SiOa61-69

ВаОз3,6-9,0VaOz3,6-9,0

LiaO1,0-4,0LiaO1.0-4.0

NaaO3,0-10NaaO3,0-10

К2О1,1-2,0.K2O1.1-2.0.

Введение окиси лити  в св зку уже в незначительных количествах снижает в зкость, повышает поверхностное нат жение и улучшает адгезию силикатных расплавов к абразиву.The introduction of lithium oxide in small amounts already in insignificant amounts reduces viscosity, increases surface tension and improves adhesion of silicate melts to abrasive.

Св зка с окисью лити  имеет низкий коэффициент термического расширени  и высокую механическую прочность. Кроме того, более низка  огнеупорность этой св зки позвол ет снизить температуру обжига абразивных изделий .Binding to lithium oxide has a low coefficient of thermal expansion and high mechanical strength. In addition, the lower refractoriness of this binder reduces the firing temperature of abrasive products.

Предмет изобретени Subject invention

Керамическа  св зка дл  изготовлени  абразивного инструмента на основе двуокиси кремни , включаюш,а  окислы алюмини , бора , кальци , магни , кали  и натри , отличаюш;а с  тем, что, с целью увеличени  ,адгезии св зки к зернам абразива, в ее состав введена окись лити , а компоненты вз ты в следуюш.ем соотношении, вес.%:The ceramic bond for the manufacture of silica-based abrasive tools, including, and the oxides of aluminum, boron, calcium, magnesium, potassium and sodium, is different from the fact that lithium oxide is introduced, and the components are taken in the following ratio, wt%:
