摘　　要：以甲酸分离枕型利乐包所得的纸、聚乙烯、铝作为实验材料,使用热重红外联用(TG-FTIR)分析技术,研究了单一组分热解产物特性和组分共热解机理。结果表明:共热解时纸和聚乙烯之间存在协同作用,且在TG-FTIR失重峰位置附近产生的影响尤为明显;铝在共热解时具有催化剂的作用,会促进聚乙烯的分解。为实现废弃纸塑铝复合包装材料的资源化利用提供科学参考和实验依据。Paper, PE and Al separated from pillow Tetra Pak with formic acid was taken as raw materials. TG-FTIR analysis technique was applied to study the characteristic of single component pyrogenation product and copyrolysis mechanism of multiple components. The results showed that there is synergism between paper and PE during copyrolysis, especially near the weight loss peak ; aluminum has the function of catalyst during copyrolysis, which promotes PE pyrogenation. The purpose was to provide reference for resource utilization of waste paper-PE-Al composite packaging material.
