Graphite anode plate and preparation method thereof
The invention discloses a graphite anode plate and a preparation method thereof. According to the preparation method, needle-shaped pitch coke and modified pitch are used as raw materials of the graphite anode plate, and the graphite anode plate is prepared through the steps of raw material pretreatment, paste preparation, forming, at least one-time roasting-dipping, roasting, graphitization and the like. The raw material pretreatment comprises crushing, screening and grinding, the paste material preparation comprises mixing and kneading and cooling, and the preparation method further comprises the steps of machining, product detection and the like. The prepared graphite anode plate has the advantages of low resistivity, high bending strength, high Shore hardness, volume density of not less than 1.75 g/cm < 3 >, low thermal expansion coefficient, high thermal conductivity, low ash content, oxidation resistance, corrosion resistance and long service life.
