Abstract
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.
Description
technical field [0001] The invention relates to a composite material and a manufacturing method thereof, in particular to a manufacturing method for compounding modified inorganic powder into building decorative surface materials, leather materials and board materials. Background technique [0002] Ceramic bricks, clay split bricks, and clay panels in building decorative surface materials are all inorganic materials that are sintered and formed at a high temperature above 1000 ° C. They have the advantages of high hardness and impact resistance. However, when it is used as a decorative surface material for high-rise buildings and external wall insulation, due to its high rigidity, it will cause large temperature and humidity shear stress, which will affect the adhesion stability, and it is heavy, so there is a hidden danger of falling off and hurting people. On the other hand, during the manufacturing process of these surface materials, a large amount of CO is emitted 2 It ...
