Graphene composite material applied in preparing spinning rubber covered roller and preparation method thereof

Abstract

The invention discloses a graphene composite material applied in preparing a spinning rubber covered roller and a preparation method thereof. The graphene composite material comprises, by weight, 100parts of polyurethane, 32 parts of graphene, 11 parts of zinc acetate, 8 parts of high-strength carbon fiber, 1 part of antimony dioxide, 1 part of cobalt aluminate, 2 parts of electrolyzed silver powder, 4 parts of allyl nitrile-styrene dipolymer, 3 parts of epoxy fatty acid methyl ester, 3-7 parts of SDS mineral powder, 1-3 parts of polymerized aluminum sulfate, 2-4 parts of cyclohexanone, 1-5 parts of 3-aminopropyl triethoxy silane and 1-3 parts of (3-lauroamide propyl) trimethyl ammonium sulfate. The graphene composite material is reasonable in component arrangement, the preparation methodis simple, and performances of the spinning rubber covered roller can be improved effectively; the graphene composite material has excellent wear resistance, so that strength of the rubber covered roller is enhanced, softness of the surface of the roller is ensured while the surface of the roller has certain friction coefficient, and static electricity and spinning burrs can be avoided effectively.

Description

technical field [0001] The invention relates to the technical field of carbon materials, in particular to a graphene composite material used in the preparation of textile rubber rollers and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional crystal that is exfoliated from graphite material and composed of carbon atoms with only one layer of atomic thickness. In 2004, Andre Geim and Konstantin Novoselov, physicists at the University of Manchester, successfully separated graphene from graphite and confirmed that it can exist alone. Bell Prize in Physics. Graphene is both the thinnest material and the strongest, with a breaking strength 200 times stronger than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is currently the thinnest and strongest material in nature. If a piece of graphene with an area of ​​1 square meter is used to make a hammock, it can bear a cat wei...
