▎ 摘 要
NOVELTY - Preparing a high temperature resistant graphene material involves weighing 100 pts. wt. graphite, 3-7 pts. wt. microcrystalline graphene, 1-5 pts. wt. fluororubber, 1-20 pts. wt. silicone, 10-30 pts. wt. styrene-butadiene rubber, 15-25 pts. wt. zinc sulfate monohydrate, 1-5 pts. wt. expanded vermiculite, 2-6 pts. wt. mullite fiber, 8-16 pts. wt. zirconia, 5-15 pts. wt. manganese dioxide, 20-30 pts. wt. paraffin, 10-30 pts. wt. MMA, 3-7 pts. wt. ACR, 0.1-0.5 pts. wt. alumina, and 2-6 pts. wt. coupling agent. The graphite, mullite fiber and paraffin are ground into a grinder for 35-55 min, passed through a 100-300 mesh sieve, and then dried in an oven for 20-40 min. The microcrystalline graphene, fluorine rubber, silicone and zinc sulfate monohydrate are taken, put into a reaction kettle equipped with a thermometer, a heating device and a stirring device, and the temperature is raised to 45-65 degrees C, stirred for 30-50 min, and the stirring speed is 200- 400 r/min. USE - Method for preparing a high temperature resistant graphene material. ADVANTAGE - The method enables to prepare a high temperature resistant graphene material, which is energy efficient, accurately prepared, has synergistic effect between each component, notched impact strength 80-120 J m, easy to use, good thermal conductivity, simple process and is widely used. DETAILED DESCRIPTION - The expanded vermiculite, manganese dioxide, MMA and ACR are taken, heated to 90-100 degrees C, constant temperature reacted for 60-70 min, stirred uniformly, and then put into a twin-screw extruder for melt plastic granulation, injection molding sample strip. The remaining raw materials are further added, mixed at 200-400 degrees C for 80-90 min, and then placed in a tube furnace and calcined under a nitrogen atmosphere, and calcined and then allowed to stand for cooling.
