Abstract

1,075,473. Laminates; moulding in stages. DURIRON CO. Inc. July 30, 1964, No. 30253/64. Headings B5A and B5N. [Also in Division F2] A laminate comprises a flexible backing member 22 of rubber or synthetic plastics having a plurality of recesses on one surface thereof and a sintered plastics layer 24, e.g. of polytetrafluorethylene, having a plurality of integral projections 25 on one surface meshing with the recesses in the backing member and secured thereto by adhesive. Each projection may taper from base and tip towards the centre (Fig. 5, not shown). To form the laminate, powdered plastics material is placed on a perforated metal plate (31) (Fig. 2, not shown) in a mould (30) and is compacted by a plunger (34) and heated to sinter it. The layer formed is then stripped from the metal plate, placed in a mould with the projections upwards, coated with adhesive, and a mass of uncured rubber, or thermosetting or thermoplastic material, placed thereon and the whole cured under heat and pressure. The mould may be shaped to form an article such as a diaphragm or piston (Figs. 7-11, not shown). Before lamination the plastics sheet 24, if of P.T.F.E., may be degraded by treatment with a solution of sodium in anhydrous liquid ammonia. The backing member 22 may be of silicone rubber, polyurethane, styrene-butadiene copolymer, epoxy resin, butadiene-acrylonitrile copolymer, polythene, polypropylene, polystyrene, a vinyl polymer or copolymer, or chlorinated rubber. The adhesive used may comprise an epoxy resin or a conventional rubber adhesive.
