Flexible reinforced gasket

Abstract

A reinforced gasket material. A non-metallic scrim layer is interposed between layers of gasket material to provide strength to the gasket material. The layers of the gasket material can include binding agent to aid adhering to each other and to the non-metallic scrim layer. The non-metallic scrim layer can also be coated in binding agent. The layers of the gasket material can include high-temperature sealing material, compressed fiber, exfoliated graphite, or polytetrafluoroethylene.

1 . A reinforced gasket material comprising:
 a first gasket material layer;   a second gasket material layer; and   a non-metallic scrim layer interposed between the first gasket material layer and the second gasket material layer;   wherein the first gasket material layer and the second gasket material layer comprise high-temperature sealing material, compressed fiber, exfoliated graphite, or polytetrafluoroethylene.   
     
     
         2 . The reinforced gasket material as recited in  claim 1 , wherein the non-metallic scrim layer comprises fiber glass, ceramic fibers, aramid fibers, graphite fibers, carbon fiber, and polymeric fibers. 
     
     
         3 . The reinforced gasket material as recited in  claim 2 , wherein the non-metallic scrim layer comprises two or more non-metallic scrim layers. 
     
     
         4 . The reinforced gasket material as recited in  claim 1 , wherein the non-metallic scrim layer is a woven non-metallic scrim layer having a warp or weft of the mesh in the range of from 30 per inch to 2 per inch. 
     
     
         5 . The reinforced gasket material as recited in  claim 1 , wherein the non-metallic scrim layer has a thickness in the range of from 0.002 inches to 0.025 inches. 
     
     
         6 . The reinforced gasket material as recited in  claim 1 , wherein the first gasket material layer and the second gasket material layer further comprise binding agent. 
     
     
         7 . The reinforced gasket material as recited in  claim 6 , wherein the binding agent comprises organic binding agent. 
     
     
         8 . The reinforced gasket material as recited in  claim 1 , wherein the non-metallic scrim layer is densified and cured to the first gasket material layer and the second gasket material layer. 
     
     
         9 . The reinforced gasket material as recited in  claim 1 , wherein first gasket material layer and the second gasket material layer comprise a high-temperature sealing material, the high-temperature sealing material comprising:
 80 wt % or greater non-oxidizing high temperature filler;   20 wt % or less high temperature fiber; and   6 wt % or less binding agent.   
     
     
         10 . The reinforced gasket material as recited in  claim 9 , wherein the non-oxidizing high temperature filler comprises mica, vermiculite, talc, wallastonite, kaolinite, and pyrophyllite. 
     
     
         11 . The reinforced gasket material as recited in  claim 9 , wherein the high temperature fiber comprises ceramic fibers, mineral wools, or glass fibers. 
     
     
         12 . The reinforced gasket material as recited in  claim 9 , wherein the binding agent comprises NBR, SBR, natural rubber, neoprene, EPDM, or fluoroelastomers. 
     
     
         13 . The reinforced gasket material as recited in  claim 1 , wherein the first gasket material layer and the second gasket material layer comprise non-asbestos compressed fiber. 
     
     
         14 . The reinforced gasket material as recited in  claim 13 , wherein the non-asbestos compressed fiber comprises:
 80 wt % or less filler;   10 wt % or greater binding agent; and   2 wt % or more fiber.   
     
     
         15 . The reinforced gasket material as recited in  claim 14 , wherein the filler comprises wallasonite, kaolinite, talc, mica, vermiculite, or pyrophyllite. 
     
     
         16 . The reinforced gasket material as recited in  claim 14 , wherein the binding agent comprises organic binding agent. 
     
     
         17 . The reinforced gasket material as recited in  claim 16 , wherein the organic binding agent comprises styrene-butadiene resin or nitrile-butadiene resin. 
     
     
         18 . The reinforced gasket material as recited in  claim 14 , wherein the fiber comprises mineral wools, ceramic fibers, or glass fibers. 
     
     
         19 . The reinforced gasket material as recited in  claim 1 , wherein the non-metallic scrim layer is coated with a binding agent. 
     
     
         20 . The reinforced gasket material as recited in  claim 1 , wherein the reinforced gasket material comprises two or more non-metallic metal scrim layers interposed between the first gasket material layer and the second gasket material layer.
