A new type of environmentally friendly waste slag porous ceramic-silica sand composite brick and its preparation method

Abstract

The invention discloses a novel and environmental-friendly waste residue porous ceramic-silica sand composite brick and a preparation method thereof. The composite brick comprises a ceramic substrate, a silica sand surface material and a bonding agent. By adjusting and optimizing formula composition of the ceramic substrate, formula composition of the silica sand surface material, formula composition of the bonding agent, surface treatment of the ceramic substrate, process optimization of silica sand surface material applying and bonding agent spraying and a surface decoration method, the surface of the prepared novel and environmental-friendly waste residue porous ceramic-silica sand composite brick product appears stone-like gloss, the pattern is rich, the texture is clear, stone imitation is lifelike, durability is achieved, and color changing and aging are avoided; the excellent performance of traditional building ceramics is achieved, and the substrate has a special porous structure, so that the composite brick has the special effects of small density, small weight, heat insulation and sound insulation; and meanwhile the technology has high universality and is easy to popularize in the industry.

Description

Technical field: [0001] The invention relates to the technical field of preparation of wall decoration materials used in buildings, in particular to a new type of environmentally friendly waste slag porous ceramic-silica sand composite brick and a preparation method thereof. Background technique: [0002] At present, the wall decoration materials used in buildings include paint, wallpaper, wall covering, traditional ceramic tiles, etc. The construction of paint is inconvenient, not durable, and the surface pattern is not rich enough. The surface pattern of wallpaper and wall covering is rich, but it is easy to absorb moisture and deteriorate. It is suitable for outdoor use, and its fire performance is not good, but the traditional ceramic tiles are large in size and good in density, which will greatly increase the weight of the wall, and the sound insulation effect is poor, especially the bonding of some traditional ceramic tiles with low water absorption and the wall The st...

Problems solved by technology

[0002] At present, the wall decoration materials used in buildings include paint, wallpaper, wall covering, traditional ceramic tiles, etc. The construction of paint is inconvenient, not durable, and the surface pattern is not rich enough. The surface pattern of wallpaper and wall covering is rich, but it is easy to absorb moisture and deteriorate. It is suitable for outdoor use, and its fire performance is not good, but the traditional ceramic tiles are large in size and good in density, which will greatly increase the weight of the wall, and the sound insulation effect is poor, especially the bonding of some traditional ceramic tiles with low water absorption and the wall The strength is poor, and it is easy to fall off after a long time of use, posing safety hazards, especially some traditional ceramics with low water absorption cannot be used for the walls of some high-rise buildings. Due to the current technical difficulties, it is difficult to fully recycle the large amount of solid waste generated in the ceramics, which will cause certain damage to the environment. Therefore, if we can develop a ceramic with a small volume density, sound insulation, and rich decorative patterns on the surface of traditional ceramics, refractory, and resistance. Combustibility, acid and alkali resistance, high strength, etc.; at the same time, a new type of environmentally friendly waste porous ceramic-silica sand composite brick that can use a large amount of ceramic waste that is difficult to recycle at present is not only energy-saving and environmentally friendly, but also provides a favorable path for the transformation and upgrading of ceramic bricks. way
