PURPOSE:To obtain the titled construction material for residential use at low cost, free from any fracture due to internal pressure caused by the cubical expansion of the heat storage material contained, by homogeneous dispersion in a base material of polyethylene pellets prepared by incorporation of a latent heat storage material and a specific substance followed by swelling then carrying out molding. CONSTITUTION:The objective construction material 1 can be obtained by homogeneous dispersion in a base material 3 of polyethylene pellets 6 prepared by incorporation of (A) an organic latent heat storage material and (B) a substance compatible with the component A but insoluble to water followed by swelling, then carrying at molding. The melting points of the components A and B to be used fall in temperature ranges higher and lower than the molding temperature, respectively. |
