Artificial bone material and preparation method thereof
The invention provides an artificial bone material and a preparation method thereof, and the preparation method comprises the following steps: mixing biological ceramic mixed powder, fully refined paraffin, beeswax and oleic acid to obtain biological ceramic wax slurry; the biological ceramic wax slurry is injected into an artificial bone mold through hot die-casting forming, demolding is conducted after forming, and an artificial bone wax blank is obtained; embedding the artificial bone wax blank into an active adsorbent, and de-waxing to obtain an artificial bone biscuit; and carrying out glue removal and air pressure sintering on the artificial bone biscuit to obtain the artificial bone material. Biological ceramic mixed powder, fully refined paraffin, beewax and oleic acid are used as raw materials, an artificial bone wax blank with high dimensional precision is formed through hot die casting, through the design of de-waxing, de-gluing and air pressure sintering, deformation in the de-waxing, de-gluing and air pressure sintering processes is effectively prevented, the dimensional precision is guaranteed, processing treatment after forming is not needed, and the production cost is reduced. The artificial bone material with high dimensional precision can be obtained, and the problem that the artificial bone meeting the requirement is difficult to process due to processing difficulty caused by high ceramic brittleness is solved.
本发明提供一种人工骨材料及其制备方法，包括：将生物陶瓷混合粉、全精炼石蜡、蜂蜡和油酸混合，得到生物陶瓷蜡浆；通过热压铸成型将生物陶瓷蜡浆注入人工骨模具中，成型后脱模，得到人工骨蜡坯；将人工骨蜡坯埋入活性吸附剂中，排蜡，得到人工骨素坯；将人工骨素坯进行排胶和气压烧结，得到人工骨材料。本发明以生物陶瓷混合粉、全精炼石蜡、蜂蜡和油酸为原料，通过热压铸成型出高尺寸精度的人工骨蜡坯，经排蜡、排胶、气压烧结的设计，有效防止排蜡、排胶、气压烧结过程中的变形，保证尺寸精度，无需成型后的加工处理，即可得到高尺寸精度的人工骨材料，避免了陶瓷脆性大而导致的加工困难进而难以加工出符合要求的人工骨的问题。
