Description

铝酸酯改性碳酸钙粉的制备方法
技术领域
本发明属于一种碳酸钙粉体的生产方法。
背景技术
目前，碳酸钙已广泛应用于造纸、塑料、塑料薄膜、化纤、橡胶、胶粘剂、密封剂、日用化工、化妆品、建材、涂料、油漆、油墨、油灰、封蜡、腻子、毡层包装、医药、食品(如口香糖、巧克力)、饲料中，其作用有：增加产品体积、降低成本，改善加工性能(如调节粘度、流变性能、硫化性能)，提高尺寸稳定性，补强或半补强，提高印刷性能，提高物理性能(如耐热性、消光性、耐磨性、阻燃性、白度、光泽度)等。重质碳酸钙的生产工艺流程有两种。干法生产工艺流程：首先手选从采石场运来的方解石、石灰石、白垩、贝壳等，以除去脉石；然后用破碎机对石灰石进行粗破碎，再用雷蒙(摆式)磨粉碎得到细石灰石粉，最后用分级机对磨粉进行分级，符合粒度要求的粉末作为产品包装入库，否则返回磨粉机再次磨粉。湿法生产工艺流程：先将干法细粉制成悬浮液置于磨机内进一步粉碎，经脱水、干燥后便制得超细重质碳酸钙。
经中国公开专利检索，查到碳酸钙发明专利申请53件；没发现与本专利申请相同的方案。
