A composite light-weight thermal insulation decorative ceramic exterior wall brick and its preparation method

Abstract

The invention discloses a compound type light heat-preservation decorative ceramic external wall tile and a manufacturing method of the compound type light heat-preservation decorative ceramic external wall tile. The external wall tile is composed of three layers, the lower layer is a surface decorative layer, the middle layer is a closed air hole heat-preservation layer, and the upper layer is an open air hole structural layer. All materials are mixed, distributed three times according to layers (the lower layer, the middle layer and the upper layer), formed at one time, dried and sintered through laser, edges are cut off, and the surface is decorated (in an ink-jet printing or 3D-printing mode). Uniform and fine sealed air holes can be formed in the compound type light heat-preservation decorative ceramic external wall tile, the water absorption rate is 0.3-2 percent, the air hole rate reaches 40-60 percent, the extension strength is 60-80 MPa, the heat conduction coefficient is 0.2-0.7 W / (M.K), and the compound type light heat-preservation decorative ceramic external wall tile has good heat-preservation, heat-insulating, waterproof and flame retardant properties, has a decorative effect, is firmly combined with a wall body, is convenient to construct, and is safe and reliable to use.

Problems solved by technology

Although the preparation method is advanced, the energy consumption is low, and there is no pollution, the raw materials used are all high-quality nano-ceramic raw materials. The products are new ceramics and have nothing to do with light-weight thermal insulation and decorative exterior wall bricks (traditional ceramics)

[0008] At present, using industrial waste or waste, adopting sintering methods with low energy consumption and low pollution, optimizing the process and conditions, improving the microstructure, making the thermal insulation layer and decorative layer organic compound, and the construction is convenient, safe and reliable has become the main research trend. , in order to achieve this goal, different waste residues or waste materials are introduced into the product formula and the preparation process is optimized, which improves the mechanical properties of the insulation brick to a certain extent. However, it still cannot fundamentally solve the performance problem in the traditional ceramic preparation method. Disadvantages such as high consumption, heavy pollution, and potential safety hazards in use are extremely unfavorable to current pollution control and haze reduction
