摘要

丙烯腈-丁二烯-苯乙烯(ABS)树脂是目前应用广泛的工程塑料。由于其优异的力学性能和高流动性,它被用于熔融沉积成型(FDM)技术。本文采用水热剥离法制备了氮化硼纳米片(BNNS)作为ABS树脂的纳米填料,并采用熔融共混法制备了用于FDM打印的ABS/BNNS复合线材。结果表明:获得了层数较少的BNNS;在ABS树脂基体中加入BNNS可有效提高复合材料的导热性。当BNNS添加量为15 wt%时,复合材料的导热系数提高到0.369 W/(m K),比纯ABS (0.174 W/(m K))提高了120.06%。此外,BNNS还提高了复合材料的力学性能、热稳定性和熔体流动速率,从而使ABS复合线材更适合FDM打印。

Preparation and properties of ABS/BNNS composites with high thermal conductivity for FDM
Abstract Acrylonitrile-butadiene-styrene (ABS) resin is a widely used engineering plastic at present. Due to its excellent mechanical properties and high fluidity, it is utilized in fused deposition molding (FDM) technology. In this paper, boron nitride nanosheets (BNNS) were prepared by hydrothermal exfoliation and used as nano-fillers for ABS resin, and ABS/BNNS composite wires for FDM printing were prepared by melt blending method. The results showed that BNNS with fewer layers were obtained; the addition of BNNS to the ABS resin matrix could effectively enhance the thermal conductivity of the composites. When the addition amount of BNNS was 15 wt%, the thermal conductivity of the composite increased to 0.369 W/(m K), which was 120.06 % higher than that of pure ABS (0.174 W/(m K)). In addition, BNNS also improves the mechanical properties, thermal stability, and melt flow rate of the composites, thus making ABS composite wires more suitable for FDM printing.
