白炭黑是橡胶、塑料、涂料等化工制品的重要填料,煤矸石制取白炭黑是其高附加值利用手段之一.利用煤矸石提铝后的酸渣,制备低模数水玻璃,经新鲜酸渣提模,制取与工业水玻璃模数(n≈3.6)相近的高模数水玻璃.以二氧化碳为沉淀剂,经碳化反应制取白炭黑.采用单因素实验和正交实验相结合,确定出最佳的工艺条件:(1)煤矸石酸渣制备高模数水玻璃:提模时间1.0h、提模温度60℃及液固比为4∶1；(2)高模数水玻璃制备白炭黑:反应温度80℃、反应时间2.5h、水玻璃密度1.075 g/mL、水玻璃模数3.3、搅拌速率为350 r/min、二氧化碳浓度为20％.所制白炭黑质量好,吸油值2.2 mL/g,白度90％以上,纯度85％以上.
