Problems solved by technology

[0004] However, there are few commercialized building thermal insulation coatings at present, and there are defects such as poor water resistance and pollution resistance, which make the thermal insulation effect of reflective thermal insulation coatings decay significantly, and the weather resistance is poor. Reflective thermal insulation coatings with high water resistance and pollution resistance relatively rare

Abstract

The invention provides waterborne heat-reflection colorful paint, and relates to the technical field of paint. The waterborne heat-reflection colorful paint is prepared with waterborne polyurethane emulsion, nano zinc oxide, rheological auxiliaries, heat-reflection pigments and additives. According to the waterborne heat-reflection colorful paint, by adopting base materials low in solar heat absorption rate and excellent in weather and water resistance, the weather and water resistance and heat reflection performance of the paint are effectively improved, the color of the paint is beautiful, and the color of an exterior wall of a building after coated with the paint is attractive.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based heat-reflecting colorful coating. Background technique [0002] Driven by the global response to the energy crisis and climate warming, the development of low-carbon economy is becoming the trend of world economic and social transformation, and is the fundamental way to solve the energy crisis, coordinate economic development and protect the climate. At present, in addition to vigorously developing nuclear power, photovoltaic cells, bio-energy and wind energy, optimizing energy consumption, especially building energy consumption, has become another important way to achieve a low-carbon economy. Building energy consumption is one of the main aspects of the total energy consumption of our society, which is 2-3 times that of developed countries, most of which are caused by heating and air conditioning. With the increasing popularity of heating and air-conditioning fa...
