Abstract

1401378 Coated asbestos fabrics JOHNSMANVILLE CORP 28 Feb 1973 [2 March 1972] 9890/73 Heading B2E [Also in Division D1] A coated fabric i.e., Fig 1 comprises: an open weave fabric layer 12, said fabric layer being made of blended strands comprising asbestos yarns intertwined with aromatic polyamide fibres or polyester fibres; and a layer of an elastomer 16 bonded to each side of the fabric with elastomer extending through the weave openings to adjoin the layers. The elastomer is preferably a fluoroelastomer applied as a composition comprising: fluoroelastomer 60 to 80 wt % (preferably 72.5); magnesium oxide 4 to 20 wt % (10.85); medium thermal carbon black 4 to 40 wt % (10.85); polyethylene 0.5 to 10 wt % (1.44); diamine 0.5 to 6 wt % (2.18); and polyester liquid 0 to 15 wt % (2.18). The preferred fabric is a woven fabric of a blended yarn having an aromatic polyamide or polyester core round which is wound asbestos fibres to form a sheath and finally the asbestos yarns have further yarn(s) of aromatic polyamide or polyester wound round them. The asbestos yarns may each comprise a cotton strand embedded in asbestos. The fabric is preferably primed with a cement comprising a dilute solution of the fluoroelastomer compositions by spraying or dipping. A first layer of the coating composition is then applied, Fig 4, by passing the composition in a plastic state through the nip of heated rollers 28, 30 then onto the fabric which passes from a roller 34 through heated rollers 30, 32. The composition is thereby pressed into the holes 18, Fig 1, between the yarns of the fabric. A further coating of the composition is then applied to the other side of the yarn in like manner, whereby the further coating reaches the first coating through the holes 18. The further coating is then dusted with mica powder before being fed to a takeup roll with a rubber sheet under tension, which causes the elastomer composition coatings to be squeezed together. After each coating step the elastomer is steam vulcanised.
