High-thermal-conductivity polynorbornene composition resin and preparation method thereof

The preparation method comprises the following steps: weighing a heat-conducting filler, an antioxidant, a dispersing agent and norbornene composition raw materials according to a mass ratio, uniformly dispersing and mixing to obtain a raw material A, adding a co-catalyst and a time control agent into the raw material A according to a mass ratio, uniformly stirring, and carrying out heat preservation for 2-3 hours to obtain the high-heat-conductivity polynorbornene composition resin. Uniformly dispersing to obtain a component A; weighing the heat-conducting filler, the antioxidant, the dispersing agent and the norbornene composition raw materials according to the mass ratio, dispersing and mixing uniformly to obtain a raw material B, adding the main catalyst solution and the pigment into the raw material B according to the mass ratio, and dispersing uniformly to obtain a component B; the component A and the component B are injected into a preheated mold at 70 DEG C through a two-component injection machine ac
