Light heat insulation building material and preparation method thereof

Abstract

The invention discloses a light heat insulation building material and a preparation method thereof. The light heat insulation building material is prepared from, by weight, 120-150 parts of Portland cement, 5-10 parts of polyimide, 40-50 parts of straw chips, 20-30 parts of limestone powder, 10-15 parts of aluminum nitride powder, 4-5 parts of ammonium persulfate, 10-15 parts of superfine calcium carbonate, 6-10 parts of silicon carbide, 4-5 parts of barium carbonate, 2-4 parts of zirconium tetrafluoride, 4-6 parts of polyphenylene sulfide, 8-15 parts of organic montmorillonite, 4-5 parts of microcrystalline wax and 2-4 parts of chromium boride. Due to the reasonable proportion, the compressive strength and flexibility of the building material are improved; meanwhile, as aluminum nitride powder, silicon carbide, zirconium tetrafluoride and other ingredients are added, the material has the heat insulation and sound insulation effects and is low in heat conductivity coefficient and good in energy saving effect; the finished wall building material is very high in both compressive strength and impact strength and is an environment-friendly building material.
