制备了注塑级塑木复合材料,研究了木粉添加量对塑木注塑成型复合材料流变性能、弯曲性能和熔融结晶性能的影响。结果表明:随木粉添加量的增加,塑木注塑成型复合材料弯曲强度、弯曲模量和熔融峰温度均出现先增加再降低的现象,当木粉添加量在30份时,复合材料弯曲强度达到30.85MPa,弯曲模量达到3065.21MPa,熔融峰温度也达到最高。 The injection molding grade WPC composites were prepared and the effects of the addition amount of wood flour on the rheological properties, flexural properties and melt crystallization properties of WPC injection molding composites were studied. The results show that the flexural strength, flexural modulus and melting peak temperature of plastic-wood injection molding composites increase first and then decrease with the increasing of the amount of wood flour. When the content of wood flour is 30, the flexural strength Reached 30.85MPa, flexural modulus reached 3065.21MPa, the melting peak temperature reached the highest.
