Abstract
Disclosed is an aqueous gel lubricant, and a method for formulating the lubricant, the lubricant having, as its basic and essential components, a major proportion of water, an effective gelling amount of an anionic heteropolysaccharide, and an effective lubricating amount of an anionic emulsion of a polysiloxane polymer. Additions of effective lubricating amounts of suspended microspherical beads enhance the lubricity and a suitable anti-freeze agent enhances the lubricant's effectiveness for low temperature applications. The lubricant is particularly adapted to facilitate the installation of cables within outer ducts or conduits.
Claims8
An aqueous gel lubricant, comprising:
- (a) a major proportion of water;
- (b) an effective gelling amount of an anionic heteropolysaccharide;
- and
- (c) an effective lubricating amount of an anionic emulsion of a polysiloxane polymer.
A method for reducing the coefficient of friction between a cable and an outer conduit through which the cable is pulled, comprising:
- preparing an aqueous gel lubricant of a major proportion of water, an effective gelling amount of an anionic heteropolysaccharide, and an effective lubricating amount of an anionic emulsion of a polysiloxane polymer;
- and
- applying said aqueous gel lubricant at the interface of the outside surface of said cable and the internal surface of said outer conduit.
