摘要
聚甲基乙撑碳酸酯(PPC)能完全被生物降解,由于生产上的需要,极性的PPC需要与非极性的PE粘结在一起,由于两者额极性相差较大,一般胶粘剂很难使两者相粘结。针对该问题,制备了一种复合胶粘剂,通过马来酸酐接枝改性PPC,以PPC-G-MAH,PE-G-MAH为主要基体材料,并加入EVA以增强体系的粘接强度。结果表明:当PPC-G-MAH,PE-G-MAH和EVA三者的质量配比为3∶3∶2时粘接效果最好。
Methyl Ethylene Carbonate( PPC) can be completely biodegraded,and due to the need of production,the polar PPC needs to be bonded with non-polar PE together,but because both frontal polarity is large,general adhesive is hard to make them bond. Aiming at this problem,a composite adhesive was prepared with using maleic anhydride grafted modified PPC and PPC-G-MAH,PE-GMAH as main base material,and adding EVA to strengthen the bonding strength of the system. The results show that when the quality ratio of PPC-G-MAH,PE-G-MAH and EVA is 3 ∶ 3 ∶ 2,their adhesive effect is the best.
