Composite material comprising flourine-containing rubber, fuel-impermeable sealing material comprising same, and process for preparing composite material
摘要：
The present invention provides a novel fluorine-containing rubber composite material having both of excellent fuel impermeability and excellent cold resistance, a fuel impermeable sealing material comprising the composite material and a process for preparing the composite material. The fluorine-containing rubber composite material comprises crosslinked particles of fluorine-containing silicone rubber dispersed in a fluorine-containing rubber. It is preferable that the fluorine-containing rubber comprises a vinylidene fluoride/tetrafluoroethylene/perfluoro vinyl ether copolymer, and the composite material has cold resistance of not more than −35° C. and fuel permeability of not more than 500 g·mm/m2·day. The fuel impermeable sealing material comprises the composite material. The process for preparing the composite material comprises a step for co-coagulation of a fluorine-containing rubber emulsion and an emulsion of crosslinked fluorine-containing silicone rubber.
