Abstract

The invention relates to a building material, and especially relates to a building material for the outer thermal insulation and the inner thermal insulation of an exterior wall and the inner thermal insulation of an interior wall, wherein the building material has the phase-transition energy-storage functions. The building material comprises the following components, by weight, 6 parts of one or more of perlite, vitreous bead or volcano zeolite, 0.1-10 parts of a phase transition material, 5-30 parts of cement, glue powder, a carboxymethyl cellulose, and one or more of an alumina fiber, and an alumina silicate fiber or ground silica, wherein the weight of the glue powder accounts for 0.05-0.5% of the total weight of the thermal building material, the weight of the carboxymethyl cellulose accounts for 0.05-0.25% of the total weight of the thermal building material, and the weight of the one or more of the alumina fiber, the alumina silicate fiber or the ground silica accounts for 1-20% of the total weight of the thermal building material. The production cost of the material of the invention is low, and the material has the efficacies of energy saving and environmental protection by using the solar energy accumulation, so the material has a very substantial market prospect.
