一种利用废旧电池钴酸锂正极材料制备的陶瓷黑色色料
摘要：
一种利用废旧电池钴酸锂正极材料制备的陶瓷黑色色料，属于陶瓷色料技术领域。以钴酸锂正极材料、软锰矿等为原料；按照第一步，从废旧锂电池里钴酸锂正极材料；第二步，制备陶瓷色料：(1)混合将上述的钴酸锂正极材料、软锰矿、氧化铁、氧化铬混合均匀后，通过粉碎机粉碎成细粉；(2)煅烧：将步骤(1)制得的细粉置于匣钵内，在1300℃的温度下煅烧1.5—2小时，除去原料中含有的有机杂质；(3)水洗：将步骤(2)煅烧后的成品通过破碎机破碎后，在70－80℃的热水中浸洗15－20分钟，再用冷水冲洗10分钟；(4)粉碎：将步骤(3)制得成品料用球磨机按照成品料：球石：水＝1:1.8:2的比例，进行研磨至颗粒为300－350目的细粉，即为陶瓷黑色色料。
摘要（英）：

The invention discloses ceramic black pigment prepared by utilizing a waste battery lithium cobalt oxide cathode material, and belongs to the technical field of ceramic pigment. The lithium cobalt oxide cathode material, pyrolusite, and the like are adopted as raw materials. The ceramic black pigment is prepared by a first step of preparing the lithium cobalt oxide cathode material from waste batteries; and a second step of preparing the ceramic pigment, wherein the second step includes (1) a step of fully mixing the lithium cobalt oxide cathode material, the pyrolusite, ferric oxide and chromic oxide and crushing the mixture into fine powder by a crusher, (2) a step of calcination, namely a step of adding the fine powder prepared in the step (1) into a sagger, and calcinating the fine powder at 1300 DEG C for 1.5-2 h to remove organic impurities in the raw materials, (3) a step of water washing, namely a step of crushing a product obtained by calcination in the step (2) by a crusher,subjecting the crushed product to immersion cleaning in hot water having a temperature of 70-80 DEG C for 15-20 min, and then washing the crushed product with cold water for 10 min, (4) a crushing step, namely a step of grinding the finished product material prepared in the step (3) into fine powder the particle size of which is 300-350 meshes and which is the ceramic black pigment, with the ratioof the finished product material, ballstone and water being 1:1.8:2.
