摘　　要：以玄武岩纤维(BF)、聚乳酸(PLA)为主要原料,再与成核剂TMC-210、硅烷偶联剂KH-550、环氧扩链剂KL-E4370B和填料纳米碳酸钙通过熔融共混制备3D打印玄武岩纤维/聚乳酸复合线材。讨论了纤维含量、成核剂用量、硅烷偶联剂用量、环氧扩链剂用量、纳米碳酸钙用量对复合线材力学性能的影响。结果表明:w(BF)以20%~30%为宜;TMC-210对于复合线材强度增强效果不明显;w(KH-550)为7.5%、w(KL-E4370B)为4%、w(纳米碳酸钙)为7.5%时,复合线材力学性能最佳。The basalt fiber(BF)/polylactic acid(PLA)composite wire for 3D printing was prepared by using basalt fiber and polylactic acid as the main raw materials,and then melt blending with nucleating agent TMC-210,silane coupling agent KH-550,epoxy chain extender KL-E4370B and filler nano calcium carbonate.The influence of fiber content,nucleating agent amount,silane coupling agent amount,epoxy chain extender amount and nano calcium carbonate amount on the mechanical performance of the composite wire was discussed.The results showed that w(BF)was suitable for 20%~30%;the reinforcement effect of TMC-210 on the strength of the composite wire was not obvious;when w(KH-550)was 7.5%,w(KL-E4370B)was 4%,and w(nano calcium carbonate)was 7.5%,the mechanical performance of the composite wire was optimal.
