Abstract
1,216,937. Moulding disc friction elements. JOHNS-MANVILLE CORP. 13 Dec., 1968, No. 59283/68. Heading B5A. A disc friction element is made by impregnating an asbestos yarn with a rubber composition, coiling the yarn to form a blank disc and pressing the disc in a direction parallel to its axis at a high pressure and temperature to consolidate the yarn and cure the rubber composition. This composition comprises (in parts by weight), rubber 16-24%; thermosetting resin 18-30%; zinc oxide 10-20%; carbon black 12-20%; sulphur 6-14%; barytes 13-22% and rubber accelerator 0À5-1%, dissolved in a volatile rubber solvent, e.g. gasoline. Preferably the rubber composition forms 40-60 wt. per cent of the impregnated yarn, the rubber is a butadiene styrene copolymer, the resin is a phenol-formaldehyde resin, the pressure is about 3000 p.s.i. and the temperature is between 350‹ and 400‹ F.
