耐高低温聚乙烯(PE)防滑包装材料的制备与研究
|
摘要
以自制A型、B型和外购E型热熔胶为防滑涂层,喷涂于PE包装薄膜表面,经后期热处理分别制得新型PE防滑包装材料AE-S-PE、BE-S-PE与EE-S-PE。通过对材料室温(25℃)、高温(70℃)和低温(-20℃)条件下摩擦系数、力学性能和粘结强度进行表征,研究并对比了3种防滑包装材料在各温度条件下的防滑性能、粘结强度和力学强度,并确定性能最佳的防滑材料投入实际应用。结果表明,BE-S-PE防滑包装材料在相同定量和温度条件下的摩擦系数、力学性能和粘结强度均优于AE-S-PE和EE-S-PE材料,当定量为70g/m~2时其在室温、高温和低温条件下摩擦系数分别为1.356,2.097,0.866;粘结强度等级均为5B。因此BE-S-PE材料具有更好的耐高低温性,并最适合作为一种耐高低温防滑材料应用于运输包装领域。
New PE anti-skid packaging materials AE-S-PE,BE-S-PE and EE-S-PE,which were respectively used self-made formula A,B type and purchased E type hot melt adhesives as anti-slip coatings,were prepared by thermal spraying and heat treatment method.The friction coefficient,mechanical properties and bond strength of three kinds of antiskid packaging materials were characterized and compared at room temperature(25 ℃),high temperature(70℃)and low temperature(-20℃),and the materials with optimal performance were obtained into practical application.The results show that the friction coefficient,mechanical properties and bond strength of BE-S-PE were superior to those of AE-S-PE and EE-S-PE under the same quantitative and temperature.At 25,70 and-20℃,the friction coefficient of spraying was 1.356,2.097 and 0.866,respectively,and the bond strength grade was 5 Bwhen the spraying quantity was 70 g/m2.Therefore,BE-S-PE has better resistance perfomance to high and low temperature,and is most suitable for application in transportation packaging as a kind of anti-skid material.
