Preparation method of graphene modified slurry heat insulation material
The invention provides a preparation method of a graphene modified slurry heat insulation material. According to the method, firstly, expanded perlite, polystyrene particles, graphene, aluminum silicate fiber, lecithin and glycerol are added into a stirring machine; stirring and mixing are carried out; then, an obtained mixture A is added into a reaction kettle; heating is performed; phenolic resin and diphenyl silanediol are added; then, a mixture B is added into a backflow device; absolute ethyl alcohol is added; heating back flow, filtering and drying are carried out; finally, a mixture C is subjected to temperature rise under the vacuum condition; gelatin, dibutyltin dilaurate and n-butyl borate are added; stirring, temperature rise, stirring and cooling to room temperature are performed, and the graphene modified slurry heat insulation material is obtained. The folding-resistant intensity of the obtained heat insulation material can reach more than 10MPa; the absorption rate is lower than 25 percent; the heat conduction coefficient is higher than 0.08W*(mk)-1.
