Abstract:

A halogen?free flame retardant LX?15 and a permanent antistatic agent MH?2030 were added into a glass?fiber?reinforced polyamide 6(PA6/GF)matrix to prepared a series of compounds through melt blending. The flame retardant, thermal stability, antistatic and mechanical properties of the compounds were characterized using vertical combustion tester, insulation resistance tester, thermogravimetric analyzer, cantilever beam impact tester and microcomputer controlled universal tester. The results indicated that with the addition of only 15 wt% LX?15, the flame retardant level of PA6/GF achieved a UL 94 V?0 classificaton. Their surface resistance decreased down to 1.1×108 Ω with the addition of only 20 wt% MH?2030. The compounds achieved a V?0 classificaton, and their surface resistivity decreased down to 1.1×108 Ω when 25 wt% of LX?15 and 20 wt% of MH?2030 were added together. Their antistatic property could be maintained for a long time. Meanwhile, their tensile strength, notched impact strength and initial decomposition temperature were 103 MPa, 15.3 kJ/m2 and 376 ℃, respectively, which are still acceptable in comparison with the values of 143 MPa, 22.3 kJ/m2 and 382 ℃ for pure PA6/GF.
