Abstract

The invention relates to a high-temperature coating capable of catalyzing dioxins, which comprises 35-70% of ceramic aggregate which comprises 32-60% of aluminum oxide, 1-5% of zirconium silicate and 2-10% of zirconium oxide; 0.5-2% of mica powder. 1-5% of carbon nanotubes; 0.5 to 2% of graphene; 0.1-2% of yttrium oxide; 0.1-2% of cerium oxide; 1-5% of palladium oxide; 1-8% of V2O5; and 1-5% of TiO2. Through reasonable matching of the raw materials, the coating has good compatibility, shows good strength, hardness, corrosion resistance and other properties in a high-temperature complex environment, does not fall off or crack after being used for a long time, and effectively protects a boiler or a pipeline from being eroded; according to the invention, through component selection, a good effect of catalytic decomposition of dioxins can be achieved. The coating can enable heat transfer of a boiler and a pipeline to be more uniform, and dioxins can be further catalytically degraded while the performance of the coating is improved.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a high-temperature coating capable of heat resistance and corrosion resistance and capable of catalytically decomposing dioxins in a high-temperature environment. Background technique [0002] With the development of my country's economy, the urban population is increasing rapidly, and the domestic waste is also increasing. The current methods of waste disposal include landfill and incineration. Landfill will inevitably lead to secondary pollution. At present, the more effective way is to dispose of garbage through incineration. The waste incineration process inevitably faces the problem of boiler corrosion under high temperature environment. At the same time, due to the complex composition of waste, new pollutants will be produced during the incineration process. Dioxin is currently the most concerned pollutant. [0003] For the protection of pipelines and boilers in high...
