The invention discloses a preparation method of a graphene elastic screen cloth enhanced carbon fiber fishing rod, and belongs to the technical field of polymer materials. The preparation method is characterized in that at first, expanded graphite is peeled to form a graphene dispersion liquid, then the graphene dispersion liquid is spray-dried to prepare graphene micro-sheet powder, the graphenemicro-sheet powder is dispersed into single component thermoplastic elastic polyurethane resin to prepare slurry, the slurry is sprayed or painted on a latticed PP board, after the slurry is completely dried, graphene elastic screen cloth is obtained; then the graphene elastic screen cloth is combined with carbon fibers to prepare carbon fiber prepreg, and finally the prepreg is cut and rolled toprepare the fishing rod. According to the preparation method, graphene is dispersed into thermoplastic elastic polyurethane resin in advance, then graphene elastic screen cloth with a small thicknessis prepared by a spraying or painting technology, finally the graphene elastic screen cloth is combined with carbon fibers, the problem that the agglomeration of graphene in resin happens easily whengraphene is directly dispersed in resin for preparing carbon cloth is solved, the situation that the distribution of graphene in carbon cloth is uneven is improved, the stress defects are reduced, andthe bearing force of the fishing rod is obviously enhanced.
