一种微晶玻璃及其制备方法和包含微晶玻璃的复合砂轮结合剂及其制备方法与应用技术

一种微晶玻璃及其制备方法和包含微晶玻璃的复合砂轮结合剂及其制备方法与应用，所述微晶玻璃的原料包括高岭土、二氧化硅、三氧化二硼、二氧化锂、钠长石、钾长石、滑石、白云石、五氧化二磷和氧化钇，由上述原料制得的玻璃可以在900‑1020℃下得到完全由微晶相组成的微晶玻璃，实现了在较低温度下玻璃相的完全转化；此外，提供了一种复合砂轮结合剂，其包括质量比为(20‑50)：(50‑80)的微晶玻璃和玻璃，该结合剂中的玻璃相具有较低的流动温度，其可与微晶玻璃相一起形成对磨料颗粒的包裹，实现砂轮的低温烧结，加之结合剂中微晶相的存在使得制得的砂轮的机械强度较高。

A kind of microcrystalline glass and its preparation method, a compound wheel binder containing microcrystalline glass and its preparation method and Application

A microcrystalline glass and its preparation method, a compound grinding wheel binder including microcrystalline glass and its preparation method and application. The raw materials of the microcrystalline glass include kaolin, silicon dioxide, boron trioxide, lithium dioxide, albite, potassium feldspar, talc, dolomite, phosphorus pentoxide and yttrium oxide. The glass made from the raw materials can be completely obtained at 900-1020 \u2103 The glass-ceramic composed of the microcrystalline phase realizes the complete transformation of the glass phase at a lower temperature; in addition, a compound wheel binder is provided, which includes the glass-ceramic and the glass with a mass ratio of (20 \u2011 50): (50 \u2011 80). The glass phase in the binder has a lower flow temperature, which can form a package of abrasive particles together with the microcrystalline phase to realize the low-temperature burning of the wheel In addition, the existence of microcrystalline phase in the binder makes the mechanical strength of the grinding wheel higher.
