Patent Office: United States of America Patent and Trademark Office. Granted Patents (USPTO) Title: Aqueous siloxane bag lubricant for tire molding
Application No: 05/215,642 Publication No: 3713851 Application Date: 1972-01-05 Publication Date: 1973-01-30
Abstract A composition useful as a bag lubricant in tire manufacturing is disclosed which composition consists essentially of (A) 1 to 20 percent by weight of an alkylmethyl-siloxane fluid having from one to 20 carbon atoms in the alkyl group and at least 1000 cs. viscosity at 25.degree. C., (B) 2 to 20 percent by weight of a material selected from the group consisting of (1) polyalkylene glycols having a molecular weight of at least 500 in which the alkylene oxide units are ethylene oxide units, propylene oxide units or combinations of ethylene oxide and propylene oxide units and (2) copolymers of alkylmethylsiloxanes and polyalkylene glycols in which the alkylene oxide units are ethylene oxide units, propylene oxide units or combinations of ethylene oxide and propylene oxide units, said copolymers having a viscosity of at least 200 cs. at 25.degree.C. and containing from 5 to 50 percent by weight of the alkylmethylsiloxanes, (C) 25 to 50 percent by weight of mica of 75 to 600 mesh, (D) 0.1 to 5 percent by weight of a material selected from the group consisting of (1) finely divided magnesium silicate, (2) carboxymethyl cellulose and (3) carboxyethyl cellulose, (E) 0.1 to 5 percent by weight of lecithin, and (F) 15 to 55 percent by weight of water. Alternative formulation is a copolymer of an alkylmethyl siloxane and a polyalkylene glycol in lieu of components (A) and (B) in the preceding composition.
