▎ 摘 要
NOVELTY - A graphene aerogel composite reinforced low-temperature phase-change heat storage material comprises aerogel block, barium hydroxide monohydrate and barium hydroxide octahydrate. The mass ratio of barium hydroxide octahydrate and barium hydroxide monohydrate is (90-70):1. The mass ratio of mixture of barium hydroxide monohydrate and octahydrate barium hydroxide and the aerogel block is (100-50):1. USE - Graphene aerogel composite reinforced low-temperature phase-change heat storage material (claimed). ADVANTAGE - The graphene aerogel composite reinforced low-temperature phase-change heat storage material is environmentally-friendly, has high temperature resistance, high heat conduction efficiency, improved cooling and phase separation effect, storage capacity, and increased thermal conductivity of barium hydroxide hydrate, and eliminates the phase change cooling phenomenon. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of graphene aerogel composite reinforced low-temperature phase-change heat storage material, which involves (1) mixing and heating barium hydroxide monohydrate and barium hydroxide octahydrate to completely melt under sealing state, and stirring to form a eutectic mixture, (2) immersing the aerogel block into the eutectic mixture at a melting state, heat-preserving, and cooling.
