▎ 摘  要

NOVELTY - Nano-modified high-barrier film composition comprises 60-80 pts. wt. high density polyethylene, 2-4 pts. wt. modified graphene, 0.2-1 pts. wt. modified nano silica, 0.5-1.2 pts. wt. modified nano titanium dioxide, 0.5-2 pts. wt. accelerator, 0.5-2 pts. wt. antioxidant and 0.5-2 pts. wt. light stabilizer. USE - Nano-modified high-barrier film composition. ADVANTAGE - The nano-modified high-barrier film composition has good light transmittance and excellent mechanical properties, greatly improves the barrier effect of film on gas and moisture, and also improves the waterproof and antifouling effect, and further ensures the excellent barrier effect. At the same time, the preparation method of the diaphragm is based on the conventional dry composite method in the food packing film industry, with mature technology, simple process, low cost, energy saving and environmental protection, and has broad development prospects and industrial promotion prices. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing soil stabilizer, which involves formulating the modifier, modified graphene, and modified nano silica, reacting the surfactant and nano silica to obtain modified nano silica, reacting the surfactant and nano-sized titanium dioxide to obtain modified nano-sized titanium dioxide, weighing high-density polyethylene, modified graphene, modified nano-silica, and modified nano-titanium dioxide, and putting them into a stirrer for stirring, adding accelerators and antioxidants, mixing agent and light stabilizer during the stirring process uniformly to obtain a mixture, putting the mixture into a twin-screw extruder to melt, extruding and pelletizing to obtain pellets, putting the pellets into film blowing machine for film blowing forming, to obtain the nano-modified high barrier film material, extruding into a multi-layer co-extrusion process, stretching into a film, and then performing corona treatment on surface of film.
