Title:
GRAPHITE CLAY COMPOSITE, PROCESS FOR PRODUCING THE SAME, GASKET OR PACKING BASED ON THE COMPOSITE, AND CLAY DISPERSION LIQUID USED FOR THE COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2007/114443
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a composite that can find application to various uses
in a wide spectrum of fields, for example, sealing members, such as a joint sheet,
a gasket and a packing, for use in junction portions, etc. of pipings of power plant
and chemical plant, radiation sheets, electromagnetic wave shielding members,
soundproof sheets, etc., and provide a process for producing the composite;
a gasket or packing based on the composite and a clay dispersion liquid used for
the composite. [MEANS FOR SOLVING PROBLEMS] There is provided a composite composed
mainly of graphite and clay and having the structure of graphite laminated with
and/or impregnated with clay. The composite is produced by subjecting an exfoliated
graphite sheet or film or a molding therefrom to coating with and/or immersion
in a clay dispersion liquid with clay particles dispersed therein, or by laminating
together of an exfoliated graphite sheet and/or film and a sheet and/or film composed
mainly of clay. Further, a gasket or packing is produced by molding the composite.
