PE-g-MAH粘合树脂性能的研究
|
摘要
通过双螺杆挤出机制备聚乙烯接枝马来酸酐(PE-g-MAH)粘合树脂,采用真空脱挥的后处理手段降低接枝产物的残留,考察了脱挥真空度对PE-g-MAH粘合树脂低分子残留、耐老化性以及粘接性能的影响,实验结果表明随着真空度的提高,可以有效降低PE-g-MAH粘合树脂的低分子残留程度,同时提高耐老化性能和粘合性能。在真空度为0.06Mpa的条件下粘合树脂与乙烯/乙烯醇共聚物(EVOH)的粘接强度可达到31.4 N/15 mm。
Polyethylene grafted maleic anhydride(PE-g-MAH) adhesive resin were prepared through twin screw extrusion. Vacuumizing method was used to decrease the low-molecular residual in product. The influence of different vacuum degree on residual, aging resistance and adhesive performance of PE-g-MAH was investigated. The experimental results showed that low-molecular residual was decreased while aging resistance and adhesive property were increased effectively by elevated vacuum. Peeling strength between PE-g-MAH and EVOH reached 31.4 N/15 mm with the 0.06 Mpa vacuum degree.
