METHOD FOR PRODUCING ACRYLIC RUBBER/FLUORO-RUBBER COMPOSITION, CROSSLINKED COMPOSITION, LAMINATE BODY, AND HEAT-RESISTANT AIR RUBBER HOSE

摘要

To provide a process for producing an acrylic rubber/fluorinated rubber composition, capable of forming a layer excellent in the interlayer-adhesion with a layer formed by crosslinking a fluorinated rubber. A process for producing an acrylic rubber/fluorinated rubber composition having particles of a crosslinked acrylic rubber (B) dispersed in a continuous phase of a fluorinated rubber (A), which comprises kneading a fluorinated rubber (A), a crosslinking agent for an acrylic rubber and a crosslinking coagent for an acrylic rubber to obtain a fluorinated rubber composition containing the crosslinking agent for an acrylic rubber and the crosslinking coagent for an acrylic rubber, and kneading under heating the obtained fluorinated rubber composition and an acrylic rubber (B) in a mass ratio of fluorinated rubber (A)/acrylic rubber (B)=5/95 to 50/50 to crosslink the acrylic rubber (B), and dispersing particles of the crosslinked acrylic rubber (B) in a continuous phase of the fluorinated rubber (A).
