Abstract

Abstract

The polyamide 6 (PA6) modified by LiCl was compounded with wood powder in the molten state to prepare wood powder/low melting point PA6 composites. The non-isothermal crystallization kinetics of the wood powder/low melting point PA6 composites was investigated via DSC. The results show that LiCl reduces the melting point, crystallization temperature, crystallinity and crystallization rate of PA6, while increases the crystallization activation energy. As a nucleating agent, the wood powder increases the crystallization rate of PA6, but decreases the crystallinity. The non-isothermal crystallization kinetics of the wood powder/low melting point PA6 composites were analyzed by Mo equation. The results show that F(T) value (the parameters of crystallization rate) of the low melting point PA6 is higher than that of pure PA6 and the wood powder/PA6 composites. LiCl increases the cooling rate required for PA6 to reach a relative crystallinity in unit time. On the contrary, wood powder reduces the cooling rate.
