Problems solved by technology

Most manufacturers use more epoxy resin matrix as dicyandiamide-accelerator curing system. This system is expensive and difficult to volatilize during prepreg drying. It is necessary to increase the drying temperature and prolong the drying time. Not only the production The efficiency is low, and the long-term high-temperature drying can easily cause the gel reaction of the resin

Abstract

The invention discloses a preparation method of a light high-strength fishing rod. Carbon fiber cloth is taken as prepreg cloth and is pretreated in a coating solution and dipped in an epoxy resin matrix thick liquid, a fishing rod blank is obtained after the carbon fiber cloth is wound with a tape and cured, the blank is polished, coated and assembled, and the fishing rod is prepared. The specific preparation steps comprise preparation of the coating solution, preparation of the epoxy resin matrix thick liquid and preparation of the fishing rod. The epoxy resin matrix thick liquid and a curing agent are taken as main bonding materials, a rigid stable net structure formed through chemical bond crosslinking of thermoset epoxy resin and the curing agent is used, no low molecular products are discharged in the epoxy resin curing process, and the prepared fishing rod has a smooth and compact surface as well as an excellent mechanical property.

Description

technical field [0001] The invention relates to a preparation method of a lightweight high-strength fishing rod. Background technique [0002] In the production process of fishing rods, the main factor affecting the main performance indicators such as weight, strength, stiffness and matching accuracy of fishing rods is the quality of prepreg cloth for fishing rods, and the key factor affecting the quality of prepreg cloth is the selection of suitable materials. The matrix resin and the corresponding infiltration and penetration process are formulated to improve the bonding force between the resin and the fabric. At present, the most used resin matrix is ​​high temperature curing phenolic resin and medium temperature curing epoxy resin. However, during the curing process of phenolic resin, water and other low-molecular products must be discharged, causing some micropores and air bubbles in the interior and surface of the blank, which seriously affects the mechanical properti...
