Abstract

The invention discloses a high-sunlight-reflectivity ceramic glaze which comprises the following raw material components in parts by weight: 8-21 parts of an aluminate, 15-36 parts of mica, 7-15 partsof scheelite, 8-16 parts of rutile, 5-15 parts of lithium aluminum silicate, 3-5 parts of quartz, 0.3-1.5 parts of a modifier and 0.5-2 parts of a dispersing agent. The glaze has excellent high sunlight reflectivity, thermal shock resistance and heat insulation performance, and is especially suitable for surface glaze of cold tiles. The invention discloses a building energy-saving porcelain glazed tile. The defects that an existing common porcelain glazed tile cannot effectively reflect sunlight and does not have the building energy-saving effect are overcome. The porcelain glazed tile not only can selectively absorb and reflect sunlight in different wavelength ranges to reduce energy absorbed by the surface of a building, but also is helpful for limiting heat from flowing to the internalenvironment, so that the heat can be effectively blocked under solar radiation, a lower tile surface temperature is kept, and the porcelain glazed tile can be used as a cold ceramic tile on the surface of the building.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high solar reflectance ceramic glaze, building energy-saving porcelain glazed tiles and a preparation method thereof. Background technique [0002] As cities around the world continue to expand, more and more forests and farms are being replaced by residential buildings. The area of ​​urban green space has been greatly reduced, and the excessive absorption of solar radiation energy by roads and buildings has led to an increase in urban temperature. This effect is called the "urban heat island" phenomenon. The urban heat island effect makes the temperature in the city center 3-5°C higher than that in the surrounding areas. After urban buildings absorb sunlight, the indoor temperature rises, which affects the comfort of people's living, and also increases the cooling energy consumption of buildings. In the next three decades, the urban heat island phenomenon will become increa...
