摘　　要：为探明硅烷偶联剂KH-550对茶梗粉/HDPE复合材料相容性与分散性的改善效果,用国家标准方法和HAAKE MARSⅢ旋转流变仪对复合材料的力学性能与流变性能进行了研究。结果表明,KH-550含量为1.8%时,复合材料的力学性能与耐水性能较好;相同应变条件下,复合材料的储存模量和损耗模量均随KH-550的增加而降低,当KH-550含量为1.8%时,复合材料的储存模量和损耗模量均达到最小值;相同温度和频率条件下,复合材料的储存模量随KH-550的增加而减小,且均在KH-550含量为1.8%时达到最小值。KH-550含量为1.8%时,复合材料的力学性能、耐水性能、界面相容性以及分散性等综合性能较好。In order to explore the effects of the silane coupling agent KH-550 on improving compatibility and dispersion of tea stems flour/HDPE composite materials , the national standard methods and HAAKE MARS Ⅲrotational rheometer were used to study the mechanical properties and rheological properties of composite materials .The results showed that the mechanical properties and water resistance of composite materials with 1.8% of KH-550 could be better.The storage modulus and loss modulus of composite materials decreased as the increase of KH-550 when strain was constant , the storage modulus and loss modulus of composite materials with 1.8% of KH-550 were both the minimum.The storage modulus reduced with the increasing of KH-550 when temperature and frequency were constant , and were both the minimum with 1.8% of KH-550.The mechanical properties , water resistance, interface compatibility and dispersion of tea stems flour /HDPE composite materials with 1.8% of KH-550 could have better overall performance .
