NOVELTY - Producing thermally conductive sheet having carbon nanotubes oriented in a staggered arrangement comprises blending carbon nanotubes with a methyl silicone oil having to obtain a premix A, blending the graphene, the composite thermally conductive filler, the polyurethane modified silicone resin, the silicone oil, the epoxy silane crosslinking agent, and the epoxy active dilution agent and other auxiliary agents to obtain a premix B, passing the premix A through an electric field and first screen and mixing with the premix B and passing on both sides to proceed, sending out forming port and extruded into a block product after a certain distance and the forming port is provided with a second screen, cutting the block product into a pre-compressed piece perpendicular to the extending direction of the carbon nanotube and perpendicular to forming pre-compressed sheet by the extending direction of the carbon nanotubes and curing and sintering the molded product to obtain a final product. USE - The method is useful for producing thermally conductive sheet having carbon nanotubes oriented in a staggered arrangement. ADVANTAGE - The method produces good orientation heat conduction effect. DETAILED DESCRIPTION - Producing thermally conductive sheet having carbon nanotubes oriented in a staggered arrangement comprises blending carbon nanotubes with a methyl silicone oil having a viscosity of less than 100 cps to obtain a premix A, blending the graphene, the composite thermally conductive filler, the polyurethane modified silicone resin, the silicone oil, the epoxy silane crosslinking agent, and the epoxy active dilution agent and other auxiliary agents to obtain a premix B having a viscosity of 900-6000 cps, passing the premix A through an electric field, passing through the first screen and mixing with the premix B and passing on both sides to proceed, passing out from the forming port and extruded into a block product after a certain distance and the forming port is provided with a second screen, cutting the block product into a pre-compressed piece perpendicular to the extending direction of the carbon nanotube and perpendicular to forming pre-compressed sheet by the extending direction of the carbon nanotubes and curing and sintering the molded product to obtain a final product, where the first screen and the second screen are provided with sieve holes, and the sieve holes inner diameter is 2-20 times the diameter of the carbon nanotube. An INDEPENDENT CLAIM is also included for the thermally conductive sheet having carbon nanotubes oriented in a staggered arrangement is prepared by the above method.
