NOVELTY - Preparing nylon heat-conducting material involves weighing nylon resin, oxide filler, protective filler, thermal filler, nano-graphene, aluminum fiber, flame retardants, plasticizers, tackifiers, coupling agents, antioxidants. The protective fillers are zeolite powder, oil-soluble phenolic resin, dimethyl silicone oil and vinyl silicone oil. The nylon resin and oxide filler are ground, sifted for 2-4 times to obtain 100-200 mesh powder. The powder are mixed and stirred with a high-speed ingredients stirrer for 20-35 minutes. USE - Method for preparing nylon heat-conducting material (claimed). ADVANTAGE - The method enables to prepare nylon heat-conducting material, which has heat-conducting efficiency, heat-conducting quality and improved service life and has very broad use prospect and is suitable for popularization. DETAILED DESCRIPTION - Preparing nylon heat-conducting material involves weighing nylon resin, oxide filler, protective filler, thermal filler, nano-graphene, aluminum fiber, flame retardants, plasticizers, tackifiers, coupling agents, antioxidants. The protective fillers are zeolite powder, oil-soluble phenolic resin, dimethyl silicone oil and vinyl silicone oil. The nylon resin and oxide filler are ground, sifted for 2-4 times to obtain 100-200 mesh powder. The powder are mixed and stirred with a high-speed ingredients stirrer for 20-35 minutes. The plasticizer, thermal filler, nano-graphene, aluminum fiber, flame retardant, plasticizer, tackifiers, coupling agents, antioxidants are mixed. The heating device heats the temperature between 95-160 degrees C and stirring. The zeolite powder, oil-soluble phenolic resin, dimethyl silicone oil, vinyl silicone oil are mixed in mass ratio of 3: 1: 1: 1. The zeolite powder is filtered through a vibrating screen, and the zeolite powder is placed on a horizontal vibration platform for reciprocating vibration for 35-45min. The sieve is used for filtering and zeolite powder of 50-100 mesh is selected. The oil-soluble phenolic resin, dimethyl silicone oil and vinyl silicone oil are added into the heating device. The temperature is set between 50-75 degrees C and stirred for 6-9min. The zeolite powder is put into a container and mixed oil is added. The container is placed into a high-pressure environment, ultrahigh-pressure treatment is performed and assisted with ultrasonic treatment for 15min to obtain a protective filler. The temperature of the heating device is set at 35-45 degrees C, and a protective filler is added, and the mixture is obtained after continuously stirring for 15-25min. The mixed raw material is heated using a heating device, fully heated to 240-260 degrees C, and extruded in a molten state.
