Abstract

The invention relates to a cooling coating and a cooling coating. The cooling coating includes a liquid putty, the liquid putty includes a first resin and a first filler, and the solar reflectance of the first filler in the 0.3 μm-2.5 μm band is greater than or equal to 85% , the solar reflectance of the putty layer formed by using the liquid putty in the 0.3μm-2.5μm band is greater than or equal to 88%. The cooling coating made of the cooling coating has a reflectivity of more than 88% for sunlight in the 0.3μm-2.5μm band, which can effectively reduce the indoor temperature of the building. At the same time, the construction procedure is simple, and the raw materials for the radiation cooling topcoat layer are The cost and construction cost are low, so that the raw material cost and construction cost of the cooling coating are low and the weather resistance is good.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a cooling coating and a cooling coating. Background technique [0002] In order to reduce the indoor temperature of a building, it is usually necessary to install a cooling coating on the roof or wall of the building. The traditional cooling coating includes a bottom putty layer, a supporting layer, a surface putty layer and a radiation cooling topcoat layer. There are 6 radiant cooling topcoat layers, each with a thickness of about 30-50 μm, and the total thickness of the radiative cooling topcoat layer reaches 0.2mm-0.5mm. However, the multi-layer construction of the radiant cooling topcoat layer not only leads to cumbersome construction procedures, but also the raw material cost and construction cost of the radiant cooling topcoat layer remain high. The light reflectivity is usually less than 88%. SUMMARY OF THE INVENTION [0003] Based on this, it is necessary to provid...
