摘要

采用双螺杆挤出法制备了含3、6、10 wt%二氧化硅、羟基磷灰石和膨润土的聚乳酸复合材料。用马来酸酐接枝聚乙烯增强界面相互作用。研究了填料对合金夏比冲击强度、洛氏硬度、拉伸性能和加工收缩率的影响。通过3D打印获得测试样品。含10 wt%羟基磷灰石的复合材料具有最高的冲击强度和硬度。PLA与10 wt%的羟基磷灰石和3 wt%的膨润土通过3D打印获得解剖结构。

Polymer composites for obtaining human anatomic structures

Composites based on PLA with the addition of 3, 6 and 10 wt% silica, hydroxyapatite and bentonite were obtained by twin-screw extrusion. Maleic anhydride grafted polyethylene was used to enhance interface interactions. The influence of the fillers used on the Charpy impact strength, Rockwell hardness, tensile properties and processing shrinkage was investigated. Test samples were obtained by 3D printing. The highest impact strength and hardness were obtained for the composite containing 10 wt% hydroxyapatite. PLA with 10 wt% hydroxyapatite and 3 wt% bentonite was used to obtain anatomical structures by 3D printing.
