Abstract

The invention discloses a building heat insulation material, and belongs to the technical field of building materials. The building heat insulation material is prepared from, by mass, 36-45% of ordinary Portland cement, 15-25% of ceramic waste, 15-25% of coal ash, 5-10% of magnesium oxide, 5-8% of hydrogen peroxide and 2-6% of a modification additive. Compared with the prior art, the building heat insulation material has the technical advantages that the ceramic waste, the coal ash and other industrial waste are selected and used in the formula, so that production cost is reduced, and meanwhile the environmental pollution problem brought by stockpiling treatment of the ceramic waste and the coal ash is relieved; the selected ceramic waste and coal ash can improve the heat insulation performance of the heat insulation material, and the heat insulation material has weather resistance, corrosion resistance, freezing and thawing resistance and the like; the selected modification additive has the foam stabilizing effect and further has the effect of prompting rapid coagulating and hardening of cement and the ceramic waste and rapid coagulating and hardening of cement and the coal ash.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a building thermal insulation material. Background technique [0002] External wall insulation is one of the important links in building energy-saving projects, and the basic guarantee for realizing external wall insulation is lightweight insulation materials. At present, the lightweight thermal insulation materials used in external thermal insulation projects are mainly organic combustible materials represented by polystyrene foam, which have serious fire hazards. [0003] In recent years, large-scale building fires caused by the use of such organic flammable thermal insulation materials are not uncommon, which have caused hundreds of millions of major economic losses and most personal casualties. The advancement of building energy-saving projects urgently needs an inorganic non-combustible lightweight insulation board to replace the currently commonly us...
