Claim 6:
7. A metal foil wrapped energy-storing temperature control board, comprising:
gypsum boards;
energy-storing temperature control material packaged and adhered between two layers of the gypsum boards to form an energy-storing temperature control board, and the energy-storing temperature control board is wrapped with metal foil; wherein when used as a building insulation layer, the wrapped energy-storing temperature control board is embedded between a brick layer and a gypsum layer of a wall of a building;
wherein the energy-storing temperature control material comprising:
2-10% of organic synthetic fiber based phase-change material,
20-70% of phase-change energy storage agent,
3-10% of phase-change temperature regulator,
3-7% of nucleating agent,
1-5% of thickening stabilizer,
0.1-1% of preservative, and
the balance being water, wherein
the organic synthetic fiber based phase-change material comprises one or more of a bacterial cellulose fiber, a rayon fiber, a carboxymethyl cellulose fiber, a cellulose acetate fiber, a polypropylene fiber, a polyacrylate fiber, a polyacrylamide fiber and a polyol ester fiber; and the organic synthetic fiber based phase-change material has a diameter of 10-25 μm and a length of 5 mm, a particle size of the nucleating agent is from 10 nm to 800 nm; the organic synthetic fiber based phase-change material is composed of porous fibers to load the nucleating agent so that the nucleating agent is uniformly distributed in the organic synthetic fiber based phase-change material; and
the nucleating agent is one or more of nano-calcium carbonate, nano-carbon particles, nano-magnesium silicate, nano-calcium oxide, nano-magnesium oxide, nano-cellulose and nano-lignin; and
the energy-storing temperature control material has a phase-change point of 18-40° C., a thermal conductivity of 0.1-0.9 W·m−1·K−1, and a specific heat capacity of 1000-3000 J·kg−1·K−1.
