Abstract

1362174 Coated sheet materials T B A INDUSTRIAL PRODUCTS Ltd 26 Aug 1971 [21 Sept 1970] 44903/ 70 Heading B2E [Also in Division D1] A composite sheet for use as a gasket material comprising surface coatings of fibrereinforced elastomer bonded to both faces of a metal core is produced as shown in Figure 2 by simultaneously forming curable doughlike fibre reinforced elastomer composition into a sheet and applying the sheet to one face of the metal core of indefinite length by feeding the metal core 1 and, on one face of the metal core a dough-like composition containing fibre, elastomer, curatives, fillers and a solvent system including a volatile solvent for the elastomer and a non-solvent liquid through a nip between two calender rolls 12 to spread the elastomer composition over the metal core and apply it thereto to form one coating, the non-solvent liquid preventing adhesion of the composition to the rolls, passing the coated metal core to a drying device 14 to remove the solvent system from the composition, passing the dry, but uncured, coated metal core together with further dough-like composition on the other face of the core through a second nip between two calender rolls 16 to spread the composition over the other face of the core and applied thereto to form a second coating, passing the core with its second coating to a drying device 18 to remove the solvent system from the second coating, passing the core with its coating through a further nip between two calender rolls 20 to consolidate the coatings and bond the coatings to the core, and then passing the coated core into an oven 21 to cure the composition. Preferably the fibre in the composition is asbestos, the volatile solvent is a liquid hydrocarbon, e.g. toluene and the non-solvent liquid is water. The metal core may be of woven wire gauze or expanded metal, or a perforated sheet, or preferably a plain or an embossed sheet. The core may be coated with an adhesive by drawing through bath 7 and then upwards through solvent extraction tower 9 before the dough-like composition is applied to it, preferably an adhesive which is only partly soluble in the solvent system in the composition. The adhesive may be a solution of nitrile rubber and a phenolic resin. The elastomer in the dough-like composition may comprise a styrene-butadiene.
