Processing method of zirconia ceramic mobile phone backboard
The invention discloses a processing method of a zirconia ceramic mobile phone backboard. The method comprises the following steps: performing ball milling and mixing, vacuum drying, grinding and sieving and isostatic cool pressing of 90%-95% of zirconium oxide powder, 1%-2.6% of yttrium oxide, 0.4%-2% of calcium oxide, 0.2%-0.9% of magnesium oxide, 1-1.5% of cerium oxide and 1.5%-3.7% of zinc oxide and others of additives; putting a sealed elastic mold filled with a powder mixture into a cylinder body filled with a pressure transfer medium, closing an upper end plug, and pressing the upper end plug when a frame slides to a position right above the cylinder body along a guide rail base; then, enabling pressurizing equipment to apply ultrahigh pressure to a pressure transmission medium in the cylinder body through a high-pressure oil path at the bottom of the cylinder body, and at the moment, pressing and forming the materials in the mold; and performing sintering, polishing and grinding. According to the zirconia ceramic mobile phone backboard disclosed by the invention, the cold isostatic pressing process is adopted, and various stabilizers and colorants are added, so that the toughness of a zirconia material is enhanced and the defect of high brittleness of zirconia ceramic is improved while the metal luster and jade texture of acrylonitrile absorption are achieved.
本发明公开了一种氧化锆陶瓷手机背板加工方法，包括以下步骤：氧化锆粉末为90％—95％，氧化钇1％—2.6％，氧化钙0.4％—2％，氧化镁0.2％—0.9％，氧化铈1％—1.5％氧化锌1.5％—3.7％，其余为添加剂，球磨混合、真空干燥、研磨过筛，冷等静压，将装有粉末混料的密封弹性模具，置于盛有传压介质的缸体中，然后闭合上端塞，框架沿导轨底座滑行至缸体正上方，将上端塞压住。接着，加压设备通过缸体底部的高压油路，对缸体内部传压介质施加超高压力，此时模具内的物料受压成型。烧结,抛光打磨。本发明所述的氧化锆陶瓷手机背板，采用冷等静压工艺工艺，添加多种多种稳定剂、着色剂，有吸睛的金属光泽与玉石质感的同时，增强了氧化锆材料的韧性，改善了氧化锆陶瓷脆性大的缺陷。
