High temperature resistant baffle door and manufacturing method thereof

Abstract

The invention discloses a high temperature resistant baffle door and a manufacturing method thereof, and relates to the technical field of flue gas desulfurization equipment. The technical gist is: a high-temperature-resistant baffle door, including a door body and a high-temperature-resistant coating coated on the surface of the door body. The raw materials of the high-temperature-resistant coating include the following components in parts by weight: silicone resin 100 ‑120 parts; 40‑60 parts of epoxy resin; 10‑20 parts of thermosetting phenolic resin; 20‑40 parts of porous nano powder; 10‑30 parts of high temperature resistant glue; 10‑20 parts of nano metal powder; 60‑100 parts of solvent The pores of the porous nanometer powder are loaded with silicon dioxide airgel, and the diameter of the pores of the porous nanometer powder is larger than the particle size of the silicon dioxide airgel. The high temperature resistant baffle door has the advantages of good high temperature resistance, and the coating is not easy to crack and fall off.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization equipment, more specifically, it relates to a high-temperature-resistant baffle door and a manufacturing method thereof. Background technique [0002] In the large-scale thermal power generation industry and metallurgical industry, a large amount of sulfur-containing flue gas is often discharged, which will cause air pollution and form acid rain. At present, flue gas desulfurization units are commonly used to treat sulfur-containing flue gas and then discharge it. However, when the unit fails, it is necessary to use a flue gas desulfurization baffle door to block the flue gas discharge, prevent sulfur-containing flue gas from leaking, or make the flue gas It enters other flue gas desulfurization units through the flue. [0003] In the Chinese utility model patent with the notification number CN201016473Y, a flue gas desulfurization baffle door is disclosed, which includes a frame...

Problems solved by technology

This patent uses carbon nanotubes to improve temperature resistance. Although materials with nanoporous structures have a good thermal insulation effect at low temperatures, their internal microporous structures are easily destroyed at high temperatures, and the pores are easy to collapse and sinter, resulting in insulation. The thermal effect is reduced, and the expected high temperature resistance effect cannot be achieved
