Abstract

1404335 Bitumen emulsion SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 2 Aug 1972 36027/72 Heading B1V [Also in Division F2] A composition for use in sealing leaks in gas pipes comprises an aqueous emulsion of blown bitumen and an emulsifier. Blown bitumen of softening point 50-140‹C and having a penetration between 3-60 dmm @ 25‹C may be present in an amount between 20-70% of the composition. Aromatic lubricating oil extract and an aromatic white spirit may be added to the bituminous phase. The emulsifier may be an alkali metal salt of an organic acid (e.g. potassium salt of wood rosin acid with or without lactic casein), a salt of fatty amine (e.g. alkylamine propylamines with 16-18 C atoms): a salt of a fatty amide or fatty amino acid; protein (e.g. lactic casein); colloidal clay (e.g. bentonite), or mixtures thereof. Preferably there is between 0.2-5% of emulsifier calculated on the aqueous phase. Preferably the emulsion is gelled by 0.1-5% of hydroxyalkylmethyl cellulose, or carboxymethylcellulose or cellulose, glue, lecithin or P.V.A.
