Composite graphite electrode and preparation method thereof
The invention provides a composite graphite electrode and a preparation method thereof. The preparation method comprises the following steps: S1, a step of burdening; S2, a step of mixing, kneading and forming to obtain a green body; S3, a step of roasting and dipping, comprising S31, roasting the kneaded green body, putting the roasted green body into an impregnation container, and filling the impregnation container with impregnation liquid A which is prepared from, by weight, 90-95 parts of coal pitch, 5-8 parts of oleic acid and 2-3 parts of silicon carbide, and S32, roasting the impregnated green body, then putting the roasted green body into an impregnation container, filling the impregnation container with impregnation liquid B which is prepared from, by weight, 90-95 parts of coal pitch, 2-3 parts of oleic acid and 4-8 parts of silicon carbide; and S4, a step of graphitizing to obtain the composite graphite electrode. According to the composite graphite electrode and the preparation method thereof, the prepared graphite electrode is high in oxidation resistance and long in service lifetime, and the production cost of enterprises can be reduced.
本发明提供了一种复合石墨电极及其制备方法，其中制备方法包括以下步骤：S1、配料；S2、混捏成型，得到坯体；S3、焙烧与浸渍；S31、将混捏成型的坯体焙烧后放入浸渍容器，向浸渍容器内充入浸渍液A，浸渍液A包括以下重量份的原料制成：煤沥青90‑95份、油酸和5‑8份和碳化硅2‑3份；S32、将浸渍后的坯体焙烧后放入浸渍容器，向浸渍容器内充入浸渍液B，浸渍液B包括以下重量份的原料制成：煤沥青90‑95份、油酸和2‑3份和碳化硅4‑8份；S4、石墨化，得到复合石墨电极。本复合石墨电极及其制备方法，制得的石墨电极的抗氧化性能高，使用寿命长，能给降低企业的生产成本。
