Abstract
Official abstract text for this publication.
A fluorocarbon resin composite includes a fluorocarbon resin layer on a base, in which a fluorocarbon resin constituting the fluorocarbon resin layer is crosslinked by electron beam irradiation, and the base has a desired shape obtained by machining. The fluorocarbon resin is composed of a tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer, polytetrafluoroethylene, or a mixture of the tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer and polytetrafluoroethylene. A fluorocarbon resin composite, cookware, and a roller and a belt for use in office automation equipment are each produced by applying an uncrosslinked fluorocarbon resin on a base, subjecting the fluorocarbon resin to electron beam irradiation in a low-oxygen atmosphere to crosslink the fluorocarbon resin while the temperature of the fluorocarbon resin is maintained at a temperature equal to or higher than the melting point of the fluorocarbon resin, and machining the base into a desired shape. There is also provided methods for producing them.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a roller or a belt for use in office automation equipment, comprising the steps of placing a die of an extruder in a nitrogen gas atmosphere; extruding an uncrosslinked fluorocarbon resin from the die of the extruder onto a cylindrical base; and subjecting the fluorocarbon resin to electron beam irradiation in the nitrogen gas atmosphere to crosslink the fluorocarbon resin before the temperature of the fluorocarbon resin is decreased to a temperature equal to or lower than the melting point of the fluorocarbon resin. 2. The method for producing a roller or a belt for use in office automation equipment according to claim 1 , further comprising after the uncrosslinked fluorocarbon resin is heated to a temperature equal to or higher than the melting point of the fluorocarbon resin and then subjected to electron beam irradiation in a nitrogen gas atmosphere to crosslink the fluorocarbon resin, performing rapid cooling before the temperature of a layer located below the fluorocarbon resin reaches the decomposition temperature of the layer.
