Embodiment 1
[0030] Step 1. First place the nylon 6 resin in an oven at 100°C to dry for 3-4 hours, so that the moisture content is less than 5‰; then weigh 50kg of the dried nylon 6 resin and 3kg of polyethylene octene copolymerized elastomer in proportion -Maleic anhydride copolymerization (toughening agent), 0.25kg N, N'-1,6-hexylene-bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionamide] (anti Oxygen agent), 0.25kg tris(2,4-di-tert-butylphenyl) phosphite (antioxidant), 1kg silicone powder (lubricant) and 2kg black masterbatch, and add them together in the high-speed mixer , stir and mix until uniform to obtain a mixture;
[0031] Step 2, then weigh 50 kg of aluminum nitride powder (thermally conductive insulating material) with a diameter of 40 μm, and add the mixture obtained in step 1 and the thermally conductive insulating material to the double-layer aluminum alloy with a length-to-diameter ratio of 40:1 through the main feed and side feed respectively. In the screw extruder, the ...
