Description

一种陶瓷刮板及其制备方法
技术领域
本发明涉及机电设备加工技术领域，具体为一种陶瓷刮板及其制备方法。
背景技术
刮板又称划线板，用竹片或层压板制成，是小型电机嵌线时的使用工具。在嵌线时用刮板分开槽口的绝缘纸，将已经下槽的导线理齐，并推向槽内两侧，使后嵌的导线容易入槽。在制作刮板时，刮线的部分(前端及前端两侧)要用锉刀倒圆，并用砂纸打光，以免刮线时刮破导线的绝缘层和槽底的绝缘纸，其宽度为2cm～3cm。
现有的刮板由于其自身材质原因，从而导致其本身强度不高，耐磨性差，在长时间工作时，其刮线部分往往会因为长时间工作而受损，导致对导线部分造成损伤，影响工作效果。
发明内容
针对现有技术的不足，本发明提供了一种陶瓷刮板及其制备方法，具备本身性能优越，有效满足刮线需求，使用寿命长，且本身制备工艺简单，有效保证刮板的强度和硬度，同时满足耐磨耐用的优点。
为实现上述目的，本发明提供如下技术方案：一种陶瓷刮板，包括外基板，外基板的内部包覆有芯板，芯板包括外部固定连接有芯网板，外基板的设置有刮板口；
所述外基板和刮板口设置为陶瓷材料，其按重量组份数比为：
