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。
Mainly through the AC foaming agent mass fraction, the amount of straw powder, the type of coupling agent and its mass fraction, nano-CaCO3 mass fraction single factor such as to study the best foaming process. The results showed that the minimum density was 1.008 g / cm3 and the maximum impact strength was 42.5 kJ / m2 when AC foaming agent was 2%, the minimum density was 1.09 g / cm3 when the content of straw powder was 35%, the impact strength With the maximum of 43.5 kJ / m2. With the change of the type and amount of coupling agent, the minimum density of MAH-g-PP with 4% MAH-g-PP was 1.01 g / cm3 and the maximum impact strength was 43.5 kJ / Calcium carbonate, the minimum density of 1.01 g / cm3, the maximum impact strength of 43.5 kJ / m2.
