The experimental results show that the shear strength of poly （MMA/BA/MAA）/LMPA is increased, when the LMPA is added into poly （MMA/BA/MAA）. The optimum addition of LMPA is about 4 wt pct. By adding 3 wt pct nano-SiO2 into poly （MMA/BA/MAA）/LMPA adhesive, its properties such as the shear strength, thermal stability, wear resistance and sea waterproof resistance are increased too.展开更多
