METHOD OF PREPARING REFRACTORY COMPOUND Russian patent published in 2000 - IPC

FIELD: manufacture of graphite-containing refractory materials in various industries, predominantly in production of metals. SUBSTANCE: method comprises mixing sintered granular refractory filler with liquid synthetic resin, then with graphite, then with finally divided refractory filler premixed with antioxidant which prevents oxidation of graphite during service of products, subsequently adding solid synthetic resin and finally mixing the components, and technological operation of mixing sintered granular refractory filler with synthetic resin is carried out under conditions when rarefaction of at least 0.8 atm gauge is created mixer, liquid resin being fed into mixer after granular filler is maintained at above-mentioned rarefaction for at least 5 minutes. Operation of mixing granular refractory filler with liquid synthetic resin is carried out in individual container in which rarefaction of at least 0.8 at m gauge is created therein, and mixed components are fed into mixer to be finally mixed with other components. EFFECT: more efficient preparation method. 3 cl, 1 ex
