NANOCOMPOSITE MATERIALS FOR THERMAL ENERGY STORAGE IN CONSTRUCTIONS AND PROCESS FOR PRODUCING THE SAME
The invention relates to a nanocomposite material meant to be used in constructions for energy storage and to a process for producing the same. According to the invention, the material comprises 73% polyethylene glycol having a molecular weight of either 1000, 1500 or 2000, 1% aluminium powder, 26%...

| description | The invention relates to a nanocomposite material meant to be used in constructions for energy storage and to a process for producing the same. According to the invention, the material comprises 73% polyethylene glycol having a molecular weight of either 1000, 1500 or 2000, 1% aluminium powder, 26% epoxy resin and triethylene tetramine, the resulting nanocomposite material exhibiting melting/curing intervals of 26...36, 42...46 and 46...52°C. The claimed process consists in mixing the epoxy resin with the melted polyethylene glycol and the aluminium powder, admixing the curing agent, homogenizing the resulting mixture at a temperature of 25...40°C, the mixture being then poured into the desired moulds and left 24 hours to polymerize, after 7 days there resulting a nanocomposite material having a latent heat of 92.7, 108.6 and 116.2 kJ/Kg, respectively. |
