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.
Claims20
A method for preparing a rubber-based composite material, comprising:
- polymerizing a hydrocarbon monomer composition by an atmospheric-pressure glow discharge plasma polymerization technique so as to form a polymerized film containing unsaturated bonds therein on the surface of a base material;
- and
- bonding a rubber composition to said polymerized film by heat pressure bonding so as to join said base material and said rubber together and thereby form said rubber-based composite material;
- wherein said monomer composition is diluted with a gas selected from the group consisting of He, Ar, Ne, N.sub.2, H.sub.2 and O.sub.2 and said plasma is generated by a high-frequency plasma discharge device having external electrodes that are coated with an insulator.
A method of making a rubber-based composite material, which comprises:
- forming a polymerized film having unsaturated bonds therein on the surface of a base material by polymerizing at least one monomer selected from the group consisting of saturated hydrocarbons, unsaturated hydrocarbons, and halogen-substituted derivatives thereof, by an atmospheric-pressure glow discharge plasma polymerization technique;
- and
- bonding a rubber composition directly to said polymerized film without the use of an adhesive by heat pressure bonding such that said rubber composition is internally cross-linked and cross-linking exists between said rubber composition and said unsaturated bonds contained in said polymerized film to thereby form said rubber-based composite material;
- wherein said base material is selected from the group consisting of plastics, rubbers, metals and ceramics.
