| 目的 主要研究纸尿裤回收料与玉米淀粉、木薯淀粉、PE等混合物制备共混发泡材料的过程，并讨论其在包装填充中的应用。方法 纸尿裤经过高温消毒、分离、粉碎、环氧乙烷消毒、漂白、除异味等过程分离出PE底膜和纸浆等回收料，将其与玉米淀粉、木薯淀粉、PE、添加剂等混合后在160~170 ℃下制备共混发泡材料;对该材料的密度、回弹性、压缩永久变形、水溶性、缓冲减震性能、可降解性能、重金属含量进行测试，并研究纸尿裤回收料加入量对配方1~4的影响。结果 随着纸尿裤回收PE材料的增加，其表观密度和实地密度增加约0.7 kg/m3，孔隙率约为61.81%;回弹性和压缩永久变形有所提升，当压缩变形量<25%时恢复率>90%;纸尿裤回收料的加入对缓冲减震性能影响不大;材料水溶性随防水助剂的加入逐渐减弱，降解3个月后体积减少80%~90%，质量损失率约为15.62%;随着纸尿裤回收料的加入，重金属含量有所增加，但远远小于标准值。结论 纸尿裤共混发泡材料可用作快递包装填充材料，其孔隙率高，具有一定的缓冲减震效果;水溶性和可降解性良好，可进行填埋处理，无重金属污染。设计的高效自动填充打包机提高了纸尿裤回收共混发泡材料的使用效率，其填充打包速度为人工的10~15倍。 |

| The work aims to research the process of preparing blended foam materials from diaper recycling materials mixed with corn starch, cassava starch, PE, etc., and discuss its application in packaging filling. Diapers were subject to high-temperature disinfection, separation, crushing, ethylene oxide disinfection, bleaching, deodorization and other processes to separate PE bottom films, pulp and other recycling materials. These materials were mixed with corn starch, cassava starch, PE, additives, etc., and then blended foam materials were prepared at 160-170 ℃. The density, resilience, compression permanent deformation, water solubility, shock absorption and vibration reduction performance, degradability, and heavy metal content of the material were tested, and the effect of the addition amount of diaper recycling materials on formulas 1-4 was studied. The results showed that with the increase of diaper recycling PE materials, the apparent density and bulk density increased by about 0.7 kg/m3, and the porosity was about 61.81%. Resilience and compression permanent deformation were improved, and when the compression deformation was less than 25%, the recovery rate was greater than 90%. The addition of diaper recycling materials had little effect on the shock absorption and vibration reduction performance. The water solubility of the material gradually weakened with the addition of waterproofing agents, and the volume reduced by 80% to 90% after 3 months of degradation, with a mass loss rate of about 15.62%. With the increase of diaper recycling materials, the heavy metal content increased, but it was far less than the standard value. In conclusion, diaper blended foaming materials can be used as packaging filling materials for express delivery, with high porosity and certain shock absorption and vibration reduction effects. They have good water solubility and degradability and can be landfilled without heavy metal pollution. The designed high-efficiency automatic filling and packaging machine improves the utilization efficiency of diaper recycling blended foam materials, and its filling and packaging speed is 10 to 15 times that of manual operation. |
