More Information
Summary:The invention provides a preparation method of a high-strength carbon graphite product, and the preparation method comprises the following steps: carbonizing agriculture and forestry waste biomass, pulverizing, and carrying out morphology treatment to obtain sphere-like ultrafine powder less than or equal to 3 [mu] m; and mixing the ultrafine powder with a single-component polyurethane adhesive, asphalt and calcium hydroxide, drying, molding, repeatedly dipping and roasting for 3-8 times, and graphitizing to obtain the carbon graphite product. By adopting the method disclosed by the invention, even if the agricultural and forestry waste biomass is adopted as the raw material, the compressive strength and the breaking strength of the obtained carbon graphite product are close to or even beyond those of the carbon graphite product obtained by using petroleum coke or carbon black as the raw material. Under the condition of green and environment-friendly raw materials, the performance of the carbon graphite produ
