Filling type high-thermal-conductivity composite press-in material and preparation method thereof

The invention discloses a filling type high-thermal-conductivity composite press-in material and a preparation method thereof, a multi-component mixed filling system taking epoxy resin as a heat-conducting medium material is constructed, and interface thermal resistance is reduced by selecting a high-thermal-conductivity filler, improving heat exchange efficiency and enabling filler particles to be in contact with one another, so that the heat-conducting performance of the composite press-in material is improved. A continuous chain-shaped or net-shaped 3D heat-conducting network path is formed in a polymer matrix, so that the heat conductivity coefficient of the epoxy resin-based composite material is increased, the mechanical property and thermal stability of the epoxy resin-based composite material are improved, the integrity of a furnace body is improved, the service life of a blast furnace is prolonged, the process is simple, the production efficiency is high, and the method is suitable for industrial pro
