The preparation method of nano-graphene involves mixing concentrated sulfuric acid with graphite, controlling temperature at -20--10 degrees C, stirring for 5-12 hours, stirring for 5-12 hours at 0-5 degrees C, adding potassium permanganate to carry out oxidation reaction to obtain oxidized graphite solution, mixing the oxidized graphite solution directly into cetyltrimethylammonium bromide, cetyltrimethylammonium bromide is used to flocculate and modify the oxidized graphite, filtering the modified oxidized graphite solution, washing, drying at 50 degrees C under vacuum for 24 hours. The nano-active agent is magnesium oxide, aluminum oxide, silicon nitride and boron nitride. The preparation method of modified hydrotalcite involves dispersing certain amount of magnesium aluminum hydrotalcite in deionized water to obtain slurry, heating with stirring, adding acetic acid to adjust pH to 3.7, refluxing for 3 hours, cooling, washing the product with deionized water, filtering to obtain filtrate with pH 7 and drying. An INDEPENDENT CLAIM is included for preparation method of anti-seismic and environmentally-friendly nano-film packaging material, which involves mixing PVC resin, polyarylsulfone, perfluoroalkoxy alkane resin, triglyceride trimellitate, tetraethylene glycol diheptanoate, p-toluenesulfonyl semicarbazide, fluoroalkyl modified silicone oil and 4,4'-oxybis(benzenesulfonyl hydrazide), heating at 105 degrees C for 2-4 hours and leaving the mixture still, drying, sieving to 100-200 mesh to obtain the mixture (A), mixing the mixture (A) for 3-4 minutes, adjusting the mixer temperature at 140-160 degrees C, adding nitrile rubber modified phenolic resin to the kneader and obtaining vacuum residue, (4) reducing the speed of the mixer, pulverizing the remaining components, sieving to 100-200 mesh, heating with stirring at 90-100 degrees C, cooling to 70 degrees C, unloading, subjecting to crushing treatment and screening.
