Pressed ceramic ultra-fine oilstone and preparation method thereof
The invention provides a pressed ceramic ultra-fine oilstone and a preparation method thereof, the pressed ceramic ultra-fine oilstone comprises, by mass, 90-95% of an abrasive material and 5-10% of a ceramic binder, the abrasive material is composed of corundum with a particle size of F800-F1500; the ceramic bond is composed of 5%-16% of clay, 12%-60% of boron glass, 10%-30% of bentonite, 15%-40% of dextrin powder and 8%-54% of potassium silicate. According to the pressed ceramic ultra-fine oilstone and the preparation method thereof, the paste liquid and the water glass are used for generating a correspondingly matched wetting agent, the overall connectivity is improved, the rheological property and stability of a potassium silicate solution can be improved through mixing of potassium silicate and the paste liquid and the colloidal property of dextrin, and therefore the adhesive property and heat resistance of the potassium silicate solution are improved; compared with the prior art, the method has the advantages that the connecting state is increased, the cracking condition is prevented, the occurrence of cracking, cracking and other conditions during drying is prevented, the drying period of 10-15 days can be shortened to 2-3 days at present, the time is shortened by more than 80%, the production efficiency of the oilstone is greatly improved, and the rejection rate of the oilstone is reduced.
本发明提出了一种压制陶瓷超精油石及其制备方法，按质量百分比，由90％‑95％的磨料与5％‑10％陶瓷结合剂组成，其中：磨料由粒度为F800‑F1500的刚玉组成；陶瓷结合剂由5％‑16％的粘土、12％‑60％的硼玻璃、10％‑30％的膨润土、15％‑40％的糊精粉、8％‑54％的硅酸钾组成。该一种压制陶瓷超精油石及其制备方法，使用了糊精液和水玻璃产生相应配合的湿润剂，增加了整体的连接性，其中硅酸钾与糊精液的混合，糊精的胶体性质能够改善硅酸钾溶液的流变性和稳定性，从而增加其粘接性能和耐热性，以增加其连接状态防止开裂的情况，以防止干燥时裂纹、开裂等情况的发生，并且能够将10‑15天的干燥期缩短至现在的2‑3天，时间缩短了80％以上，极大地提高了油石的生产效率，并降低了油石的废品率。
