以玉米秸秆粉和PP塑料为主要原料制备了可降解的木塑复合材料,并通过对秸秆粉的含量、偶联剂的种类及其含量等因素的控制,研究上述因素变化对可降解木塑复合材料的各项力学性能的影响。结果表明:当秸秆粉质量分数达到30%时,可降解复合材料的抗弯强度、抗拉强度、抗冲击强度均为最佳;采用MAPP作为偶联剂且含量为4%时,材料的抗弯、抗拉强度、抗冲击强度均为最佳。 In this paper, biodegradable WPC composites were prepared by using corn stover powder and PP plastic as the main raw material. Through the control of straw powder content, the type and content of coupling agent and other factors, The mechanical properties of composite materials. The results showed that when the mass fraction of straw powder reached 30%, the flexural strength, tensile strength and impact strength of biodegradable composites were the best. When MAPP was used as the coupling agent and the content was 4% Bending, tensile strength, impact strength are the best.
