摘　　要：主要通过AC发泡剂的质量分数、秸秆粉的量、偶联剂的种类及其质量分数、纳米CaCO3质量分数等单因素来研究最佳的发泡工艺。结果表明:AC发泡剂质量分数为2%时,密度最小1.008 g/cm3,冲击强度最大为42.5 kJ/m2;秸秆粉质量分数为35%时,其密度最小为1.09 g/cm3,冲击强度最大为43.5 kJ/m2;随着偶联剂种类和量的变化,得出4%的MAH-g-PP时其密度最小为1.01 g/cm3,冲击强度最大为43.5 kJ/m2;4%纳米碳酸钙时密度最小为1.01 g/cm3,冲击强度最大为43.5 kJ/m2。The best foam process was researched through the AC foaming agent content, straw content, coupling agent varieties and contents,nano CaCO3 content and parameters of the single factor. The results showed when AC foaming agent content was 2 % ,density minimum was 1.01 g/cm3 ,impact strength was the highest for 42.5 kJ/m2. When straw content was 35 % , density minimum was 1.09 g/cm3 ,impact strength most was 43.5 kJ/m2. With the changing of the content of coupling agent varieties and contents,When MAH-g-PP content for 4 % , density minimum was 1.09 g/cm3 ,impact strength biggest was 43.5 kJ/m2. When nano CaCO3 content was 4 % , density minimum was 1.01 g/cm3 , impact strength biggest was 43.5 kJ/m2.
