Phase-change temperature-control tile and production method thereof

Abstract

The invention discloses a phase-change temperature-control tile and a production method thereof. The tile is composed of a tile matrix, a phase-change temperature-control layer, and a water proof layer, wherein, the tile matrix comprises the following raw materials in parts by weight: 12-25 parts of iron mine tailing, 20-30 parts of a clay mine, 25-45 parts of waste ceramic material, 1-2 parts of carbonized silica micropowder, 10-15 parts of magnesite mine tailing, and 3-8 parts of quartz sand; the phase-change temperature-control layer is prepared by the bonding agent and a phase-transition material coated by metal organic framework according to the weight ratio of 10:1-2; the water proof layer is obtained by solidifying a heat-conduction filling material-contained aqueous resin emulsion, and the heat-conduction filling material is one of nano zinc oxide, nano titanium dioxide, and nano silica.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to a ceramic tile capable of phase change and temperature control and a preparation method thereof. Background technique [0002] With the development of the economy, consumers have higher and higher requirements for the quality of life. As an indispensable and important material in architectural decoration, ceramic tiles are a product that combines practicality and artistry, and are widely favored by consumers. . Due to the temperature difference between day and night and climate change, the temperature of the building also changes accordingly, making the living experience worse, requiring extremely high energy consumption to enable cooling or heating equipment to regulate the temperature, and the construction cost increases sharply. The application of ceramic tiles with phase change temperature regulation function in buildings is one of the effective means of building energ...

Problems solved by technology

Inorganic phase change materials have the advantages of high energy storage density, non-toxicity, non-flammability, and low cost. At present, the widely used inorganic phase change materials at room temperature mainly include Na2SO4·10H2O (sodium sulfate decahydrate) and CaCl2·6H2O (chlorinated hexahydrate) Calcium), etc., but the supercooling of inorganic salt hydrate (the phase change material does not undergo a liquid-to-solid phase transition process below the phase transition temperature) and phase separation (the water contained in the phase change material is not enough to make the inorganic salt in it completely Dissolution and precipitation) phenomenon seriously affects its use
