Abstract

The invention relates to an MHFPI type high-temperature resistant epoxy matrix resin for a carbon fibre cable core and a preparation method thereof. The MHFPI type high-temperature resistant epoxy matrix resin is composed of a multifunctional epoxy resin, an MHFPI polyimide resin, an active diluent and a curing agent with the mass ratio of 100:(1-15):(20-200):(100-300). The preparation method comprises the following steps: (1), reacting 2,2-bi(3-amino-4-hydroxyphenyl) hexafluoropropane, aromatic diamine, aromatic dianhydride and maleic anhydride to prepare the MHFPI polyimide resin; and (2), carrying out copolymerization reaction on the MHFPI polyimide resin and the multifunctional epoxy resin, then, adding the active diluent to continuously react, adding the curing agent, and stirring and mixing uniformly. The MHFPI type high-temperature resistant epoxy matrix resin disclosed by the invention is simple in preparation process, environmentally friendly and excellent in comprehensive property, and is applied to a pultrusion process; and the MHFPI type high-temperature resistant epoxy matrix resin can be applied to pultrusion of a carbon fibre cable core composite material and has wide market application prospect.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an MHFPI type high temperature resistant epoxy matrix resin for carbon fiber cable cores and a preparation method thereof. Background technique [0002] Today's transmission lines mostly use steel-cored aluminum stranded wire, which plays an important role in power transmission. However, with the rapid development of the national economy, the demand for electricity has grown rapidly, which has brought enormous pressure to the large-scale transmission of electricity. Steel-cored aluminum stranded wire has the disadvantages of heavy weight, high energy consumption, short tower spacing, and large sag. Therefore, it is necessary to study a new type of material to replace the steel core, so as to produce a light weight, high strength, and low energy consumption. Advanced core material with low profile, large tower spacing and small sag. Carbon fiber is a high-performance...
