Abstract

The invention discloses high-temperature-resisting infrared radiation energy-saving coating and a preparation method thereof. The high-temperature-resisting infrared radiation energy-saving coating isprepared from the following components: 60 to 80 parts of functional filling, 3 to 5 parts of a functional auxiliary agent and 50 to 100 parts of binding emulsion, wherein the functional filling is prepared from SiO2, MnO2, Fe2O3, Co2O3, CaCO3, B6Si and CaF2. According to the high-temperature-resisting infrared radiation energy-saving coating disclosed by the invention, a scientific formula design, especially a material selection design of the functional filling, is adopted; a preparation method of firstly mixing and pressing, then sintering to form a solid solution and finally binding and mixing is combined, so that on one hand, the thermal shock resisting stability of the coating is improved; on the other hand, the radiation effect and the energy-saving effect of a coating layer have anefficient matching ability and the efficient energy-saving effect is realized.
