Heat-conducting insulating glass fiber reinforced PA66/HDPE alloy material and preparation method thereof

The invention relates to the field of polymer materials. The invention relates to a heat-conducting insulating glass fiber reinforced PA66/HDPE alloy material. The heat-conducting insulating glass fiber reinforced PA66/HDPE alloy material is composed of the following components in parts by weight: 30-60 parts of PA66, 10-40 parts of HDPE, 10-20 parts of a flame retardant, 5-40 parts of glass fiber, 5-30 parts of a heat-conducting fiber material, 0.1-5 parts of a heat-conducting material, 1-10 parts of a compatilizer, 0.1-1 part of a lubricant and 0.1-1 part of an antioxidant. The heat-conducting silicon carbide fiber is added into a PA66/HDPE alloy, and the silicon carbide fiber penetrates through an infiltration mold, so that the silicon carbide fiber keeps a very good fibrous form in theextrusion direction; the carbon nano tube has a hexagonal network structure, so that the carbon nano tube is in lap joint with silicon carbide in the vertical flowing direction, and the heat conduction efficiency of the mate
