Grinding aid modifier for oil shale semicoke
The invention discloses a grinding aid modifier for oil shale semicoke, which is prepared by the following steps: sequentially adding 20-40% by weight of silica fume, 5-15% by weight of cross-linked polyacrylate, 5-10% by weight of lignosulfonate, 20-40% by weight of polymeric polyol, 10-15% by weight of anhydrous sodium sulphate and 0-15% by weight of vinyl acetate into a mixing container, and fully and uniformly stirring. The product provided by the invention not only has excellent grinding aiding property on oil shale semicoke, but also can greatly improve the defects of high water absorption, high adsorption, poor flowability, easy bleeding and the like, meanwhile, the raw materials are easy to obtain, the formula is reasonable, environment-friendly, energy-saving and pollution-free, the cost is low, industrial production is easy to realize, the preparation process is simple, special processing equipment is not needed, and the production cost is low. The method has good economic benefits, social benefits and environmental protection benefits.
本发明公开了一种用于油页岩半焦的助磨改性剂，是以重量百分比计，将20‑40%的硅灰、5‑15%的交联聚丙烯酸盐、5‑10%的木质素磺酸盐、20‑40%的聚合多元醇、10‑15%的元明粉、0‑15%的醋酸乙烯酯依次加入混合容器中，充分搅拌均匀所得。本发明产品对油页岩半焦不仅具有优良的助磨性，还可大大改善其高吸水、高吸附、流动性差、易泌水等缺陷，同时本发明原材易得、配方合理，环保节能无污染，成本低，易于实现工业化生产，制备过程简单，不需要特殊的加工设备，具有良好的经济效益和社会效益、环保效益。
