A fluorescent cement brick and its preparation method

Abstract

The invention relates to fluorescent cement bricks and a preparation method thereof, and belongs to the technical field of preparation of building decoration materials. The surface layer of each cement brick is prepared from the following materials in parts by weight: 50 parts of aluminophosphate cement, 18 parts of sand, 12 to 15 parts of a fluorescent powder, 6 to 9 parts of water-soluble epoxy resin, 22 to 23 parts of water, 0.2 to 0.3 part of an EVA tackifier, 0.4 to 0.5 part of an efficient polycarboxylic acid water reducing agent and 0.07 part of a thickening time control agent; the bottom layer of each cement brick is prepared from the following raw materials in parts by weight: 28 parts of sulfoaluminate cement, 12 parts of sand, 18 parts of ceramic particles, 12 parts of coal ash, 18 to 21 parts of water, 0.7 to 1.2 parts of PLA-PEG, 0.4 to 0.5 part of the EVA tackifier, 0.3 to 0.4 part of the efficient polycarboxylic acid water reducing agent and 0.07 part of the thickening time control agent. By adding the fluorescent powder in the surface layer, the cement bricks have a lighting function in the evening; the use amount of the water-soluble epoxy resin in the surface layer is reduced, so that the use amount of organic matters is reduced; by adding a little of PLA-PEG in the bottom layer, a dry shrinkage value difference between the bottom layer and the surface layer can be effectively reduced, so that the bottom layer can be better adhered to the surface layer.

Description

technical field [0001] The invention particularly relates to a fluorescent cement brick and a preparation method thereof, belonging to the technical field of preparation of building decoration materials. Background technique [0002] With the development of the country's economic life, the materials used in interior and exterior design have involved various industries such as steel, non-ferrous metals, chemicals, textiles, wood, ceramics, plastics, and glass. People's emphasis and emphasis on the spirit of the theme of interior and exterior design also requires new materials with great personality and moderate cost to realize. As far as wall and floor decoration is concerned, there are many types of materials that can be used, such as ceramic glazed tiles, marble, and granite facing tiles. furnish. Cement brick is a commonly used floor decoration material, which is firm in quality, small in bulk density, pressure-resistant and wear-resistant, and moisture-proof. With the ...

With the continuous development of the economy, people's requirements for the quality of life are getting higher and higher. Although there are luminous cement bricks on the market now, they use LEDs to emit light and need to be powered on to emit light, and most of them are used in public places such as squares and dance halls. , has a certain security risk
