High-hardness wear-resistant resin-permeable ceramic composite material as well as preparation method and application thereof
The invention discloses a high-hardness wear-resistant resin-permeable ceramic composite material and a preparation method and application thereof.The preparation method comprises the steps that silicate glass powder containing sodium potassium aluminum silicate serves as a raw material and is subjected to compression molding, and after molding, a green body is subjected to ultra-high cold isostatic pressing treatment to obtain a green body; the pressure of the ultra-high cold isostatic pressing ranges from 350 MPa to 600 MPa; carrying out high-temperature sintering on the green body, cooling, immersing in a resin solution for full permeation, carrying out warm isostatic pressing curing, and cooling to obtain the high-hardness wear-resistant resin permeation ceramic composite material. The sintering temperature of the high-temperature sintering is 600-800 DEG C. According to the method, the composite material with the hardness higher than that of Vita Enmic can be prepared under the condition of low sintering temperature, production equipment of general manufacturers can meet production conditions, and popularization is facilitated. The hardness of the resin-permeable ceramic composite material is 2.5-4.5 GPa, and the resin-permeable ceramic composite material is higher in hardness, better in wear resistance and wide in market application prospect.
本发明公开了高硬度耐磨的树脂渗透陶瓷复合材料及其制备方法和应用，其包括：以含硅酸铝钾钠的硅酸盐玻璃粉为原料，模压成型，成型后对坯体进行超高冷等静压处理，获得生坯体；所述超高冷等静压，压力为350~600MPa；对生胚体进行高温烧结，冷却后浸没于树脂溶液中充分渗透，温等静压固化，冷却后即为高硬度耐磨的树脂渗透陶瓷复合材料；所述高温烧结，烧结温度为600~800℃。本方法能够在较低的烧结温度条件下制备出硬度高于Vita Enamic的复合材料，一般生产厂家的生产设备均能满足生产条件，利于推广。本发明提供的树脂渗透陶瓷复合材料硬度在2.5~4.5GPa，其硬度更高，耐磨性更佳，市场应用前景广阔。
