Embodiment Construction

[0022] The invention relates to a high-performance infrared radiation coating for industrial furnaces and a preparation method thereof.

[0023] The infrared radiation coating is composed of infrared radiation agent, infrared radiation modifier, binder and coating additives, of which infrared radiation agent is 22-28%; radiation modifier is 8-12%; binder is 55-65%; 3 to 7% of the agent, all of which are mass percentages.

[0024] The infrared radiation agent consists of BN (boron nitride) 38-42%, SiO2 (silicon dioxide) 28-32%, Mn2O3 (manganese trioxide), 13-17%; SiC (silicon carbide), 4-6% %, Fe2O3 (ferric oxide), 3-6%, CuO (copper oxide), 3-6%; composed of.

[0025] The infrared radiation modifier is coated with zirconia of graphene, wherein 10-40% of graphene and 60-90% of ZrO (zirconia). Among them, graphene is used as a supporting framework to improve the distribution effect of zirconia.

[0026] The binder is composed of PA or silica sol and chromium oxide green, 66% o...

Abstract

The invention provides high-performance infrared radiation paint used for an industrial furnace. The paint comprises an infrared radiation agent, an infrared radiation modifying agent, a binding agent and a paint additive, wherein the infrared radiation agent comprises EN, SiO2, Mn2O3, SiC, Fe2O3 and CuO; the infrared radiation modifying agent is a zirconia coating of graphene. In the paint, a novel material of graphene and the cheaper materials of CuO, Fe2O3, SiC and the like are selected, so that the production cost can be effectively lowered; in addition, as the paint has a special structure of graphene, so that the impurity energy level and free carrier concentration in the basic materials can be remarkably increased, the using temperature of the paint is increased, and the radiation performance is remarkably improved.

Description

technical field [0001] The invention relates to an industrial coating, in particular to a high-performance infrared radiation coating for industrial furnaces. Background technique [0002] High-performance infrared radiation coating for high kiln is a special new energy-saving coating with high temperature resistance, high emissivity, corrosion resistance and high wear resistance. The coating uses an improved infrared radiation agent as a filler, which is a homogeneous system formed by grinding with components such as binders and coating additives. [0003] In my country, the energy consumption of industrial kilns accounts for about 60% of the national industrial energy consumption and 25% of the national total energy consumption. However, the average thermal efficiency of industrial furnaces in my country is less than 30%, while the average thermal efficiency of industrial furnaces in the world is more than 50%. Therefore, the energy saving of industrial furnaces has cons...
