SNTZ-101 reflective thermal insulation coating for construction can form a dense thermal protective layer on the surface of the object, which can highly reflect the infrared and ultraviolet rays of the sun’s rays, prevent the sun’s heat from accumulating on the surface of the object, and automatically reflect the heat on the surface of the object to reflect the heat on the surface of the object to the natural environment and reduce the temperature change of the object itself. At the same time, nano-functional materials with low thermal conductivity are placed in the paint to isolate the transfer of heat energy, and even when the atmospheric temperature is very high, it can block the external heat and conduct it to the inside of the object, and the three major effects ensure the constant temperature of the object coated with the paint.
