Abstract

The invention relates to pultrusion resin for a high temperature-resistant carbon fiber-reinforced cable core and a preparation method of the pultrusion resin. The resin comprises hydroxyl-containing and carboxyl-containing active polyimide resin (HCPI), polyfunctional epoxy resin, SR22000 organic silicon resin, thermoplastic bisphenol A phenolic resin, maleic anhydride, an active diluent, a curing agent and an accelerator. The preparation method comprises the following steps: putting polyfunctional epoxy resin, hydroxyl-containing and carboxyl-containing active polyimide resin, SR22000 organic silicon resin, thermoplastic bisphenol A phenolic resin and maleic anhydride into a reaction kettle, performing stirring reaction, adding the active diluent, performing the stirring reaction, then adding the curing agent and the accelerator, and uniformly stirring. The pultrusion resin provided by the invention has the advantages of convenient raw material sources, no solvent, environment friendliness, simple operation process and excellent comprehensive performance, is very suitable for a pultrusion process, is very suitable for manufacturing a high temperature-resistant carbon fiber-reinforced cable core composite material with excellent comprehensive performance by pultrusion, and has broad application prospects.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a pultrusion resin for high temperature resistant carbon fiber reinforced cable core and a preparation method thereof. Background technique [0002] As we all know, epoxy resin has many excellent properties: (1) Good bonding performance: high bonding strength, wide bonding surface, it is compatible with many metals (such as iron, steel, copper, aluminum, metal alloys, etc.) The bonding strength of metal materials (such as glass, ceramics, wood, plastics, etc.) is very high, and some even exceed the strength of the bonded material itself, so it can be used in many stressed structural parts and is the main component of structural adhesives One; (2) good processing performance: the flexibility of epoxy resin formula, the diversity of processing technology and product performance are the most prominent among polymer materials; (3) good stability performance: the curing of epoxy resin...
