Abstract
Composite article, and method of producing same, comprising a heat-resistant woven fabric substrate having a continuous heat and wear-resistant coating thereon for handling hot glass articles and the like without marring same. The heat-resistant flexible composite material is formed from a tightly woven fabric such as thermoset polyaramid fibers with a continuous imperforate coating of organic-inorganic silicone resin containing a filler of heat-resistant particulate material therein adapted to withstand extensive repeated contact with newly-formed hot glass articles. As required, the flexible composite material may be used alone or as a facing for a rigid structural member formed of metal.
Claims26
A heat-resistant flexible composite material adapted to handling hot glass articles, and the like, comprising a tightly interwoven fabric substrate formed from fibers selected from the group consisting of organic polyaramid fibers, inorganic ceramic fibers and carbon fibers, and a continuous heat-hardened coating of organic-inorganic polysiloxane resin having a finely-divided filler of heat-resistant particulate material therein extending over the glass-contacting surface of said substrate.
A heat-resistant flexible composite material adapted to use as conveyor belting, and the like, for handling newly-formed hot glass articles comprising a woven fabric substrate of substantial thickness consisting of tightly interwoven thermoset polyaramid fibers, and a continuous coating of essentially solventless silicone resin and an organic-inorganic polysiloxane resin having a filler of heat-resistant fine particulate material dispersed therein which is heat cured onto said substrate, said filler being selected from the group consisting of graphite, carbon and iron oxide.
A heat-resistant flexible composite material adapted to use in handling newly-formed hot glass articles, and the like, comprising a woven fabric substrate of substantial thickness consisting of tightly interwoven thermoset polyaramid fibers, and a continuous heat-cured coating of the following composition deposited on the glass-contacting surface of said substrate:
- 54 to 64 wt %--Methoxy Functional Reactive Intermediate Silicone Resin
- 16 to 30 wt %--Organic-Inorganic Polysiloxane Resin
- 14 to 23 wt %--Finely Divided Graphite
- 0 to 10 wt %--Finely Divided Iron Oxide.
A heat-resistant generally-flexible composite material adapted to use in handling newly-formed hot glass articles comprising a woven fabric substrate of tightly interwoven thermoset polyaramid fibers, and a continuous heat-cured coating of the following composition deposited on the glass-contacting surface of said substrate:
- 56 wt %--Methoxy Functional Reactive Intermediate Silicone Resin
- 24 wt %--Organic-Inorganic Polysiloxane Glass Resin
- 16 wt %--Finely-divided Graphite
- 4 wt %--Finely-Divided Red Iron Oxide.
The process of making a flexible composite material adapted to long-term use for handling hot glass articles, and the like, comprising the steps of taking a substrate of tightly woven fabric of thermoset polyaramid fibers of substantial thickness, applying a continuous coating of essentially solventless silicone resin having a heat-resistant filler therein uniformly over the glass-contacting surface of said substrate, and heating the filler-containing silicone resin coating and substrate to cure said resin and permanently affix the same to said fabric substrate.
The process of making a heat-resistant generally flexible composite material adapted to long-term use in handling hot glass articles, and the like, comprising the steps of severing to size and shape a substrate of tightly interwoven fabric of thermoset polyaramid fibers, applying at least one continuous coating of an essentially solventless methoxy functional intermediate silicone resin and an organic-inorganic polysiloxane resin having a finely-ground heat-resistant filler dispersed therein deposited uniformly as a thin layer over the glass-contacting surface of said fabric substrate to deeply penetrate the interstices between said fibers, and heat-curing the filler-containing resinous resin coating on said fabric substrate to permanently affix the same thereto.
