FIELD: refractory substances. SUBSTANCE: binding agent can be used for producing carbon-containing articles and masses. Agent has 60-95 wt.-% phenolic polymer as a product of polycondensation of total shale phenols with furfurol and formaldehyde where ratio of furfurol and formaldehyde polymers = (30: 70)-(70: 30) wt. -%, and 5-40 wt.-% plasticizer. EFFECT: enhanced strength, decreased porosity of refractory article and toxicity. 1 tbl, 6 ex |
