Water-based solar heat reflecting and heat insulating coating and preparation method thereof

Abstract

The invention discloses a water-based solar heat reflecting and heat insulating coating and a preparation method thereof. The coating comprises the following components in part by mass: 100 to 300 parts of water, 200 to 400 parts of base stock, 100 to 200 parts of titanium dioxide, 100 to 200 parts of heat insulating filler, 1 to 5 parts of defoaming agent, 5 to 20 parts of film-forming aid, 2 to 10 parts of thickening agent, 5 to 10 parts of dispersing agent, 1 to 3 parts of preservative and 0.5 to 3 parts of pH regulator. The water-based solar heat reflecting and heat insulating coating has the advantages of weather resistance, contamination resistance, sun reflection ratio superior to hemisphere emissivity performance, health and environmental protection, energy saving, energy consumption reduction, simple process, suitability for industrial production, energy consumption saving and cost reduction.

Description

technical field [0001] The patent of the invention relates to the field of architectural coatings, in particular to a water-based solar heat-reflecting heat-insulating coating and a preparation method thereof. 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. [0003] 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 conditi...

AI Technical Summary

Problems solved by technology

[0005] At present, there are some researches in the field of reflective heat insulation coatings in China, but there are many solvents and organic volatiles, and the product has high content of organic volatiles (VOC), which does not meet environmental protection requirements; the reflectivity is low, and the actual heat insulation effect Poor; the polymer emulsion is easy to demulsify, resulting in poor coating performance; it contains more metal particles or metal alloy particle components, so the cost is high, the stability is poor and the construction performance is poor, or sepiolite is used ingredients, the color of the paint is darker, the color palette is limited, and many other deficiencies

[0006] Generally speaking, the research on existing thermal insulation coatings is still in its infancy, and the synergistic effect between the various components is not obvious in the design of coating formulations, and the cost performance of coatings is not high.
