Abstract

The invention relates to a building material, in particular to an environment-friendly waterproof heat insulation phase change energy storage material for a building. The environment-friendly waterproof heat insulation phase change energy storage material is prepared from the following composition ingredients in parts by weight: 6 parts of one or multiple of materials from perlite, glass beads orvolcanic zeolite, 0.1 to 10 parts of phase-change materials, 5 to 30 parts of cement, 0.05 to 0.5 percent of pearl powder (accounting for the total weight of the building heat insulation material), 0.05 to 0.25 percent of hydroxymethyl cellulose (accounting for the total weight of the building heat insulation material) and 1 to 20 percent of one or several kinds of materials from aluminum oxide fiber, aluminum silicate fiber or silica powder (accounting for the total weight of the building heat insulation material). The product provided by the invention has the advantages that the production cost is low; the solar energy storage is used, so that the efficacies of energy saving and environment protection are achieved; the market prospects are very obvious.
