Preparation method of high-thickness low-temperature binder grinding needle ceramic grinding tool
The invention provides a preparation method of a high-thickness low-temperature binder grinding needle ceramic grinding tool, the high-thickness low-temperature binder grinding needle ceramic grinding tool comprises, by mass, 22%-25% of a binder and 75%-78% of a grinding material, the binder comprises, by mass, 10%-17% of superfine black clay powder, 35%-45% of low-melting-point superfine glass frit, 5%-10% of nano silicon dioxide, 1%-3% of superfine spodumene and 25%-49% of superfine slender stone powder, and the grinding material comprises, by mass, 20%-25% of a binder and 25%-49% of a grinding material. The low-melting-point superfine frit is composed of 44%-46% of silicon dioxide, 18%-20% of aluminum oxide, 1%-2% of magnesium oxide, 11%-13% of sodium oxide and 16%-20% of diboron trioxide; according to the preparation method of the high-thickness low-temperature binder grinding roller pin ceramic grinding tool, the binder needed by the high-thickness grinding tool is prepared by controlling the proportion of the superfine black clay powder, the low-melting-point superfine glass frit, the nano silicon dioxide, the superfine spodumene and the superfine slender stone powder, the sintering temperature during grinding tool production can be reduced, the sintering time can be shortened, and the service life of the grinding tool can be prolonged. Low-temperature sintering of the binding agent is achieved, the situation that a high-thickness grinding tool is prone to burning collapse, black core and the like at the temperature of 1200-1300 DEG C is avoided, and production energy consumption is reduced.
本发明提出了高厚度低温结合剂磨滚针陶瓷磨具的制备方法，按质量百分比，为结合剂22％‑25％、磨料75％‑78％，其中，结合剂由超细黑粘土粉10％‑17％、低熔点超细玻璃料35％‑45％、纳米二氧化硅5％‑10％、超细锂辉石1％‑3％、超细长石粉25％‑49％组成，低熔点超细玻璃料由二氧化硅44％‑46％、三氧化二铝18％‑20％、氧化镁1％‑2％、氧化钠11％‑13％、三氧化二硼16％‑20％组成；该高厚度低温结合剂磨滚针陶瓷磨具的制备方法，通过控制超细黑粘土粉、低熔点超细玻璃料、纳米二氧化硅、超细锂辉石和超细长石粉各成分的配比，来制成高厚度磨具所需要使用的结合剂，能够将生产磨具时的烧结温度降低，实现结合剂的低温烧结，避免了高厚度的磨具在1200℃‑1300℃时容易产生烧塌及黑心等的情况，且降低生产能耗。
