A kind of preparation method and product of brushed finish external wall dry-hanging ceramic plate

Abstract

The invention discloses a preparation method of a napping veneer exterior dry-hanging ceramic plate. The ingredients of the napping veneer exterior dry-hanging ceramic plate comprises 10-30% of high plastic clay dry powder, 20-40% of white clay dry powder, 10-30% of feldspar powder, 15-30% of coarse aggregate with the fineness of 8-20 meshes, and 0.2-7.0% of additives. According to the napping veneer exterior dry-hanging ceramic plate, a product capable of hanging in a dry-hanging manner such as back-hanging or side-hanging can be produced through a mold, is integrated with curtain wall keel, is already been widely applied in various middle-high buildings, and is high in safety reliability; as dry-hanging construction is adopted, no saltpetering problem of split bricks exists because of no cement contact; as a napping face ceramic plate is large in decorative face and is simple and efficient to mount, the labor cost and the construction time are reduced; as the plate is convenient to replace later through dry-hanging, unlike a split brick, a large-area brick does not need to be knocked off and paved again on the whole face, a broken brick is pulled out and a new brick is hung.

Description

Technical field [0001] The present invention relates to a method for preparing dry-hanging ceramic slabs, in particular to a method for preparing dry-hanging ceramic slabs with napped finishes. The invention also relates to a product prepared by the above method. Background technique [0002] The brushed veneer is naturally applied to a variety of decorative materials due to its uneven surface and rough style, especially the split bricks with brushed veneer are widely used on external walls. Split brick, also known as split brick, is a type of ceramic wall and floor tiles. Generally, all kinds of clay or feldspar and other pottery raw materials are pulverized by dry method, added with water or wet ball milled and filtered into water-containing wet sludge, and then extruded by a vacuum screw extruder equipped with a hollow die. The thin ribs connect the two bricks into a single hollow body, which is cut and dried and fired, and then split into two pieces of products along the joi...

Problems solved by technology

However, the size of the existing split brick veneer is small, generally 240*60*10mm or smaller, and there are many joints after being placed on the wall, which is not suitable for the architectural style that pursues complete unity and large specifications; the split brick is constructed by wet paste , the combination with the wall is not too high, and it is easy to peel off due to the influence of the environment and climate. Therefore, for safety reasons, the state stipulates that wet-pasted exterior wall products are prohibited for medium and high-rise buildings; in addition, wet-pasted construction is used, which is affected by cement efflorescence. After the water seepage of the split brick exterior wall, the surface is severely efflorescent, which affects the appearance; secondly, due to the small area of ​​the split brick, the labor intensity during construction is high, and the progress is slow, which often affects the construction period of the construction project.
