NOVELTY - Vehicle damping material comprises 40-60 pts. wt. core-shell emulsion, 5-10 pts. wt. fumed silica, 5-10 pts. wt. bentonite, 5-10 pts. wt. nano calcium carbonate, 5-10 pts. wt. functionalized graphene, 1-5 pts. wt. nano silver powder, 0.5-1 pts. wt. antifoaming agent, 0.5-1 pts. wt. plasticizer and 0.1-0.5 pts. wt. crosslinker. USE - Vehicle damping material. ADVANTAGE - The vehicle damping material has good solubility and antimycotic effect, and reduces vehicle inside noise pollution. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing functionalized graphene, which involves dissolving graphene in dimethylformamide and then dispersing the dissolved material ultrasonically, adding the dispersed material with purified monomer and initiator and then stirring the obtained material for 3-4 hours, and filtering and drying in to obtain functionalized graphene; and (2) a method for preparing vehicle damping material, which involves sieving bentonite, fumed silica, nano calcium carbonate, functionalized graphene and nano-silver powder through 100-200 meshes sieve, adding the sieved material with rest components and then stirring the obtained material, and adding the stirred material with deionized water to obtain the desired product.
