  • Method for preparing a rubber-based composite material
    Patent number: 5290378
    Abstract: A method for preparing a rubber-based composite material by joining a base material and a rubber composition together by heat pressure bonding can achieve strong bonding without using any adhesives, wherein a monomer is polymerized by atmospheric-pressure glow discharge plasma technique to form a polymerized film having unsaturated bonds on the surface of the base material and then the rubber composition is bonded to said polymerized film by heat pressure bonding to join the base material and the rubber together.
