| 摘要 |
This invention relates to a method of reinforcing rubber with cellulose fibers which have been modified by graft copolymerization, and a fiber reinforced rubber product. Discontinuous cellulose fibers modified by graft copolymerisation are admixed into a conventional vulcanizing rubber mixture of a natural rubber or a synthetical rubber before vulcanization. Said cellulose fibers have been modified by graft copolymerization with at least a monomer of alkyl or alkenyl acrylate, alkyl or alkenyl methacrylate or a copolymer of two or more of said monomers. Compared to untreated cellulose fibers the modified cellulose fibers have a higher adhesion to the rubber matrix. The fiber reinforced rubber product has high strength and modulus. |
