Abstract

Bamboo flour was treated with scattered agent(YB-510)to improve its flow performance, and then it was composited with low density polyethylene(LDPE)by injection to prepare bamboo flour/LDPE composite materials. The rotating rheometerwas used to study the influences of various additives on the rheological behavior of composite materials. The results showed that: the composite system with additives had the greater strain range which belongs to linear viscoelastic behaviorcompared with pure bamboo flour/LDPE system, and the storage modulus of the composite system declined with the rise of temperature. The addition of coupling agent could reduce storage modulus of the system, but the effects of lubricant and antioxidant were not significant. Frequency sweep showed that YB-510 could effectively improve the uniform dispersion of bamboo flour in matrix, reduce the viscosity of the system, and improve the processing performance of composite material.
