Abstract:

Dripping agricultural films can be obtained by adding dripping agents into the polymeric matrix, but the delaying and controlling migration of dripping agents is still challenging. Therefore, the graft of monostearic acid acrylic acid diglyceride(AGMS) and modified nano SiO2(SiO2-g-PAGMS) was prepared, and then the blend of AGMS, SiO2-g-PAGMS, polyethylene, grafted polyethylene, modified SiO2 were extruded in proportion and blown film. Acceleration dripping test at 60 ℃ showed that the maximum dripping duration of the film with SiO2-g-PAGMS, polyethylene and grafted polyethylene compound could reach 36 d. Under the same conditions, it was 1.50 times and 2.25 times higher than the film of AGMS, polyethylene, grafted polyethylene compound, and SiO2-g-PAGMS/polyethylene, respectively. Other results showed that haze and crystallization temperature of the grafted polyethylene compound/SiO2-g-PAGMS blend decreased, while melting temperature increased, and the change of tensile strength of film was less than 11%.
