Problems solved by technology

The former has been perplexing researchers because of the high-temperature oxidation of silicon carbide. Although people are trying their best to study various anti-oxidation protective agents, they cannot completely solve this problem.
The raw materials used in the latter are relatively expensive and require high-temperature (1200°C-1400°C) calcination, crushing, ball milling and other processes. The production process is cumbersome, pollutes the environment, and the cost is high, so it is difficult to promote

Description

technical field [0001] The invention relates to a nano coating, in particular to a high-temperature nano energy-saving coating. Background technique [0002] At present, high-temperature nano-energy-saving coatings at home and abroad can be roughly divided into two categories. One class is the infrared radiation coating mainly based on silicon carbide, such as the Encoat infrared radiation coating jointly launched by Harbert Beven Company of the United Kingdom and many countries in Europe and Australia. The other is an infrared radiation material based on transition metal oxides (such as chromium oxide, nickel oxide, etc.). For example, the infrared radiation coatings CRC1100 and CRC1500 launched by Japan CRC Company, the radiation powder is composed of cobalt oxide, chromium oxide, nickel oxide, manganese dioxide and so on. The former has been perplexing researchers because of the high-temperature oxidation of silicon carbide. Although people are trying their best to stud...
