Abstract

Bituminous covering composition for cable, which is used for electrical insulation, water-resistante, and weather-resistance was prepd. by mixing air blown asphalt 70% with tallowy pitch 20%, rosin(rice bran oil) 6%, polybren 630>C.S.T 2%, and polypropylene 2% at 100≰C in a cylindrical heating tank, heating at 180-200≰C for 4 hr and cooling by immediately immersing in the cooling tank.
