Description

Изобретение относитс  к производству абразивного инструментаThis invention relates to the manufacture of abrasive tools.

Известна масса дл  изготовлю ни  абразивного инструмента на ор ганической св зке, состо ща  из & абразивных зерен, жидкого увлажнител , порошкообразного св зущего и наполнител .A known mass for the manufacture of an abrasive tool on an organic bond, consisting of & abrasive grains, liquid humidifier, powdered binder and filler.

Недостаток известной массы заключаетс  в том, что абразивный ю инструмент, изготовленный на ее основе, имеет сравнительно малую разрывную прочность.A disadvantage of the known mass is that the abrasive tool made on its basis has a relatively low tensile strength.

Предлагаема  масса отличаетс  от известной тем, что в нее в качестве св зующего ввод т аминометилированныи полиоксЕфенилметилен, а в качестве увлвжнител  - жвдкую резольную смолу с содержанием фенола до 20% и влаги 6-7. Увлажни- о тель и св зущее при этом берут в соотношении 1:3-1:4.The proposed mass differs from that known in that aminomethylated polyoxyphenylmethylene is introduced as a binder, and as a binder - a liquid resole resin with a phenol content of up to 20% and moisture 6-7. The humidifier and the binder are taken in a ratio of 1: 3-1: 4.

Это обеспечивает получениеIt provides

инструмента с высокой разрывной прочностью.tool with high tensile strength.

Абразивный инструмент из такой массы изготовл ют по ойцепригн той технологии.An abrasive tool of such a mass is manufactured according to an oyceptic technology.
