Abstract

The invention provides cooling powder having an infrared heat radiation function and used for reducing the temperature of a bituminous pavement. The cooling powder having the infrared heat radiation function is prepared from the following raw materials in parts by weight: 5-10 parts of TiO2, 20-30 parts of ZnO and 60-70 parts of MgO. The cooling powder having the infrared heat radiation function has the following beneficial effects: the cooling powder having the infrared heat radiation function is ZnTiO2 and MgTiO2 mixed crystals prepared by sintering the raw materials including TiO2, ZnO and MgO; and unique substance composition and lattice form ensure that the cooling powder having the infrared heat radiation function has a relatively high infrared emission rate. The cooling powder having the infrared heat radiation function can be used for preparing a pavement waterproof layer with a bituminous pavement structure or an effect for reducing the urban heat island effect.

Description

technical field [0001] The invention relates to a cooling powder with infrared heat radiation function for lowering the temperature of asphalt pavement. Background technique [0002] Urban roads occupy a large proportion of urban underlying surfaces. Asphalt pavement materials absorb heat quickly and have high heat capacity. The structure of ordinary asphalt pavement is a gray body close to a black body. In the entire solar spectrum range, its average absorption rate is as high as 90%. Above, the reflectivity of visible light and infrared is very low, and the absorbed solar radiation energy is greater than the thermal radiation energy emitted to the external space, which leads to the continuous accumulation of heat in the asphalt surface layer, which increases the temperature of the road surface, and the equilibrium temperature of the road surface in high temperature seasons can even be reduced. When it reaches about 70°C, high-temperature diseases such as road rutting and w...
