(54) АБРАЗИВНАЯ МАССА ДЛЯ ИЗГОТОВЛЕНИЯ ШЛИФОВАЛЬНОГО(54) ABRASIVE MASS FOR THE MANUFACTURE OF GRINDING
ИНСТРУМЕНТАTOOLS
1one
Изобрйтеиие относитс к производству абразивных инструментов предназначенных дл механической обработки стекла и др. хрупких материалов .The invention relates to the production of abrasive tools for the machining of glass and other fragile materials.
Известны абразивные инструменты, содержащие абразив и в качестве св зующего полистирол 1.Abrasive tools are known that contain abrasive and polystyrene 1 as a binder.
Однако и})струмент, изготовленный на известной св зке, при обработке хрупких неметаллических материалов имеет низкую износостойкость, низкие скорости щлифовани и не обеспечивает требуемого качества обработки поверхности.However, even}) the fabric made on the well-known bond, when processing fragile non-metallic materials, has low wear resistance, low grinding speeds and does not provide the required quality of surface treatment.
Цель изобретени - повышение износостойкости инструмента.The purpose of the invention is to increase the tool durability.
Указанна цель достигаетс тем, что абразиГНа масса дополнительно содержит 1к.либутадиеновый каучук при следующем соочиошении компонентов,This goal is achieved by the fact that the abraziGNa mass additionally contains 1k.libutadiene rubber at the next combination of components,

В качестве абразива масса содержит карбид бора.As an abrasive mass contains boron carbide.
Кроме того,св зующее введено в виде сополимера стирола с полибутадиеновым каучуком.In addition, the binder is introduced in the form of a copolymer of styrene with polybutadiene rubber.
Модифицированный полибутадиеновый Modified polybutadiene
to каучук полистирола имеет высокую адгезию к карбиду бора, обеспечива при этом высокую износостойкость инструмента . Хороша адгези дает возможность вводить в массу больщое коли15 чество абразивных зерен, что обеспечивает высокую шлифующую способность инструмента.Polystyrene rubber has a high adhesion to boron carbide, while providing high tool durability. Good adhesion makes it possible to introduce into the mass a large amount of abrasive grains, which ensures a high grinding ability of the tool.
Инструмент изготавливают следующим образом.The tool is made as follows.

Предварительно гранулированный полистирол развальцовывают на гор чих валках вальцев, нагретых до 100120 С, н по получении рачвальцонанной пленки nojniCTnp.)jra постепенно ввод т в нес порошок карбида бора и провальцовываюг до получени гибкой гомогепной шкурки. Из шкурки на прессах с помощью пресс-формыPre-granulated polystyrene is flared on hot rolls of rollers heated to 100120 ° C, according to the nojniCTnp.) Jra film, which is gradually introduced into the boron carbide powder and rolled up to obtain a flexible homogenous skin. Pelt on the presses using the mold
