Preparation and 3D Printing of Attapulgite-Reinforced PA6 Composite Filament
To improve the mechanical properties of polyamide 6(PA6)3D printed samples,KH-550 modified attapulgite(ATP)was introduced into polyamide 6(PA6).PA6/ATP composite materials were prepared by melt blending,and the wires using for 3D printing were formed by single screw extrusion.The orientation behavior of ATP during the 3D printing process and its influence on the mechanical properties of PA6 were studied,and the reinforcement mechanism of the filler was discussed.The results show that an appropriate amount of ATP can significantly improve the mechanical properties of PA6,the tensile strength and Young's modulus reach 73.8 MPa and 3.11 GPa,respectively,which are 35%and 27%higher than those of pure PA6,the ordered orientation of ATP in PA6 matrix was observed.
