The heat-insulating energy-saving coating can be divided into a blocking type, a radiation type and a reflection type according to the energy-saving principle, and the three heat-insulating energy-saving coatings have different performance characteristics, application occasions and energy-saving effects due to different heat-insulating mechanisms. The reflective energy-saving paint is also called as heat reflective paint, can enable a coated object to generate a temperature adjusting effect under the irradiation of sunlight, and is an energy-saving material which is simple, convenient and easy to implement and has obvious effect.
In construction engineering, inorganic heat-reflective coatings are generally made by mixing film formers with reflective fillers, film-forming aids, water, dispersants, and the like. Currently, commonly used film formers mainly include silicate, silica sol, and fluoro (meth) acrylate polymer emulsions. The inorganic heat reflection coating prepared from the film forming material has good heat reflection performance, acid and alkali resistance, weather resistance and contamination resistance. However, the long-term use shows that the inorganic heat reflection coating can be applied to a small span of an environmental temperature range, cannot simultaneously have good cold resistance and high temperature resistance, and has poor cold and heat cycle resistance.
