METHOD FOR MAKING COMBINATION TYPE GAS BOTTLE Russian patent published in 2003 - IPC

FIELD: manufacture of gas bottles. SUBSTANCE: method comprises steps of applying onto metallic carcass sealing layer of crude rubber mixture; winding upon said layer reinforcing layer of fiber glass reinforced plastics; simultaneously performing vulcanization of rubber mixture layer and polymerization of reinforcing envelope; making sealing layer of rubber mixture on base of butadiene-acrylonitrile rubber containing as vulcanizing system 2.5-Bis(tret-butylperoxyisopropyl)benzene, triethylene glycol dimetacrylate and N, N' metaphenylenedimaleide at next relation of ingredients (mass.p.): butadiene-acrylonitrile rubber, 100; 2.5-Bis(tret-butylperoxyisopropyl)benzene, 2.5 - 4.0; N,N'metaphenilenedimaleimide, 0.8 - 2.0; triethylene glycol dimetacrylate, 10 - 15; antiager, 0.5 -3.0; zinc oxide, 3 - 5; stearic acid, 1 - 3; technical carbon, 60 - 90. EFFECT: enhanced fluid tightness, strength, heat- and cold resistance of sealing layer. 2 dwg, 3 tbl
