Integral zirconia ceramic cutting tool material and preparation method thereof
The invention belongs to the technical field of ceramic cutting tools, and discloses an integral zirconia ceramic cutting tool material and a preparation method thereof. The integral zirconium oxide ceramic cutting tool material is prepared by the following steps: mixing 80-90wt% of zirconium oxide powder, 1-2.5 wt% of stearic acid, 6-10wt% of paraffin, 0.5-2.5 wt% of dibutyl phthalate and 2.5-5wt% of high-density polyethylene at 160-180 DEG C, performing screw extrusion granulation, performing injection molding, performing extraction degreasing, discharging rubber at 750-850 DEG C, and sintering at 1380-1500 DEG C. The method for preparing the zirconia ceramic thick-wall cutting tool material has the excellent characteristics of mass production, high production efficiency and high product yield. The integral cutting material is fine and uniform in crystal grain and good in wear resistance, and a cutter manufactured by the integral cutter material can be used for processing parts such as high-strength graphite, non-ferrous metals or modified plastics at a high speed.
本发明属于陶瓷切削刀具技术领域，公开了一种整体氧化锆陶瓷切削刀具材料及其制备方法。该整体氧化锆陶瓷切削刀具材料是将80～90wt％氧化锆粉，1～2.5wt％硬脂酸，6～10wt％石蜡，0.5～2.5wt％邻苯二甲酸二丁酯，2.5～5wt％高密度聚乙烯在160～180℃混炼，螺杆挤出造粒，注射成型，萃取脱脂，750～850℃排胶，1380～1500℃烧结制得。本发明的氧化锆陶瓷的厚壁刀具材料的方法具有可大批量生产，生产效率高，产品良率高的优异特点。本发明的整体刀具材料晶粒细小均匀耐磨性好，以其制造的刀具可用于高速加工高强度石墨，有色金属或改性塑料等零件。
