<p>A modified inorganic powder composite material and a preparation method thereof are provided. Raw materials comprise 6-30% of cement, 0.5-4% of emulsion powder, 0-3% of acrylic acid polymer latex, 0-3% of pigment and balance of the modified inorganic powder. The modified inorganic powder is at least one of waste construction cement building block powder, waste powder from stone material factory, waste powder from ceramic factory and sandy soil which are modified with rare earth coupling agent, aluminate coupling agent or titanate coupling agent etc. The method comprises steps of mixing the raw materials, adding water and stirring to obtain homogeneous slurry; coating, pouring or extruding the slurry to a mould; curing at room temperature or drying at a temperature of 50-150°C, then demoulding to obtain the composite material. The composite material can be fabricated to construction decoration face material with proper flexibility, plate with low flexibility or cladding material with high flexibility by using various moulds and adjusting the proportion of raw materials. The invention fully utilizes waste construction materials and common materials, and is economical and environment friendly.</p> |
