Abstract
A moulded material for friction linings for brakes, clutches, &c. consists of a fibrous material and a binding agent with or without fillers, and molybdenum disulphide homogeneously dispersed therethrough, in amount, e.g. of 0.1 to 10 per cent by weight of the material. The binder is preferably a mixture of 5 parts (by weight) of natural rubber and 3 parts of a thermosetting phenol-formaldehyde resin. In the example, two cold solutions of natural rubber and asphaltic bitumen (as plasticizer) in trichlorethylene are mixed together; the fillers carbon black, graphite, sulphur and litharge are then stirred in, followed by the molybdenum disulphide and chopped wire yarn (i.e. asbestos and cotton-covered wire) and finally by the phenol-formaldehyde resin. The resulting paste is extruded in the cold, and after alternate drying and compressing operations is moulded into the desired shape and baked.ALSO:A friction lining composition consists of a fibrous material and a binding agent with or without fillers, and molybdenum disulphide homongeneously dispersed therethrough in amount, e.g. of 0.1 to 10 per cent by weight of the composition.
