Preparation method of graphene elastic screen cloth enhanced carbon fiber fishing rod

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a method for preparing a graphene elastic mesh cloth reinforced carbon fiber fishing rod. Background technique [0002] The existing carbon fishing rods are made of different grades of carbon fiber cloth and fixed on the set mold through the coiling machine, and are cured at high temperature per unit time. The carbon fiber cloth is usually pre-impregnated with carbon fiber tow. made of resin. The fishing rod made by this technology has the characteristics of lightness, stiffness and good resilience. Most of the high-end fishing rods at home and abroad use this technology; The hanging strength within 45 degrees is better, but the twisting strength at 90 degrees is lower. [0003] The current ordinary fishing rod is used under long-term high-strength and high-frequency conditions, and its strength and toughness will decrease relatively quickly, and its resistance to ins...

Problems solved by technology

However, the preparation method also has the following problems when applied to the production of fishing rods: the method uses graphene to be dispersed in the resin and then composited with carbon fibers. The distribution in the carbon cloth is uneven, the overall strength of the fishing rod is uneven after being made into a fishing rod, and the local fracture situation still cannot be solved; in addition, the barrier effect of the graphene sheet will prevent the resin in the carbon cloth from being able to communicate between the carbon fiber and the graphene. The circulation between the graphene and the carbon fiber layer even hinders the circulation of the resin between the carbon fiber layers, resulting in insufficient connection force between the graphene and the carbon fiber. After being made into a fishing rod, it is very easy to break under high-frequency and high-strength use.

[0005] The Chinese invention patent application with the publication number CN102273433A discloses a manufacturing method of a fishing rod, which adopts a layer of epoxy mesh cloth superimposed on the carbon fiber cloth, and then changes the angle between the reference side of the main cloth and the carbon fiber grain of the carbon fiber cloth to make the The finished fishing rod has better toughness, and the twist is not easy to break; however, this method has the following disadvantages: a layer of epoxy mesh is superimposed on the carbon cloth, although the strength of the carbon cloth is slightly improved, but the weight of the carbon cloth is greatly increased. And this method of adding additional layers does not improve the strength of carbon fiber itself, so the overall improvement effect of strength is very limited
