Influence of Additives on Extruding Rheology of Bamboo-Plastic Composite

摘要

Both stabilizer and couple-agent can affect the melt index of composite materials. Moreover, the different varieties of same stabilizer and couple-agents also results in the difference of melt index of composite materials. The result of melt index test showed that, under the test condition of load 21.6 kg and temperature 190 degC, the melt index of bamboo-plastic composite which was added hot stabilizer 'lead salt' is averagely small by 15.84 g/(10 min) than that of hot stabilizer 'rare earth', and that the melt index derived from 1.5 portions of aluminate is averagely small by 15.09 g/(10 min) than that of 1.5 portions of titanate. The result also revealed that the melt index of bamboo-plastic composite using 1.5 portions of titanate as couple-agents is averagely big by 8.94 g/(10 min) comparing with the negative control (without couple-agents), and that the melt index derived from 1.5 portions of aluminate is averagely big by 23.47 g/(10 min) than that of negative control.
