Problems solved by technology

[0003] Most of the existing infrared radiation energy-saving coatings are mainly metal oxides, which are mainly used in high-temperature equipment with an operating temperature below 1400 ° C, and have achieved certain energy-saving effects; but at the same time, the existing infrared radiation energy-saving coatings are When working under the environment, the radiation rate will decrease with the increase of the working temperature, the coating will peel off, and the coating will pollute the product to a certain extent, and the working temperature needs to be further increased.

Abstract

The invention relates to an energy-saving paint resistant to high temperature and high infrared radiation. The energy-saving paint resistant to high temperature and high infrared radiation is characterized by being prepared from, by weight, 40-100 parts of a radiation agent, 150-320 parts of filler and 72-180 parts of a binder. The radiation agent and the filler are weighed according to a proportion and premixed, then the mixture and the binder are subjected to high-shear mixing and dispersing, then micro-nano grinding and dispersing are carried out, and the energy-saving paint resistant to high temperature and high infrared radiation is obtained. The infrared radiance of the paint is kept within 0.85-0.95 at high temperature, and thus the paint can be widely applied to various kilns and can effectively improve the heat efficiency of kilns.

Description

Technical field: [0001] The invention relates to a coating, in particular to a high-temperature-resistant infrared high-radiation energy-saving coating and a preparation method thereof. Background technique: [0002] Infrared radiation energy-saving coating is an inorganic coating with high emissivity in the infrared band. It is widely used in military, aerospace, metallurgy, non-ferrous and refractory material manufacturing industries. It is a new type of heat radiation and energy-saving material. After the application of infrared radiation energy-saving coatings in the kiln, the radiation heat transfer inside the kiln can be strengthened, the heat utilization efficiency of the kiln, product quality and output can be effectively improved, and the refractory material of the kiln matrix can be protected to a certain extent. The service life of the kiln body can be extended, and the emission of carbon dioxide can be reduced to produce an environmental protection effect. [0...
