FIELD: impregnating materials. SUBSTANCE: invention aims, in particular, at protecting wood crosssites and bars against fungal and bacterial rot. Antiseptic contains alkylbenzene-processing high-viscosity tar mixed with low-viscosity ethylbenzene tar, 60-80 and 20-40 wt.-%, respectively, and 40-50% in common based on antiseptic weight) and wide oil fraction 220-450 C from thermal process mixed with medium-distillate fraction 180-350 C from thermal catalytic process 80-85 and 15-20 wt.-%, respectively, and 50-60 wt. -% in common. EFFECT: achieved high fungicidal and impregnating capability with high aggregating stability and low toxicity. |
