Abstract

The invention discloses a water-based high-temperature-resistant coating for high-temperature coating, and a preparation method thereof, and belongs to the technical field of water-based coatings. Thecoating is prepared from, by weight, 30-60 parts of a high-temperature-resistant emulsion, 0.05-2 parts of an organic silicon defoaming agent, 0.5-3 parts of an amine neutralizer, 0.3-3 parts of a silane coupling agent, 0.3-3 parts of a phosphate coupling agent, 0.1-2 parts of a base material wetting agent, 1-15 parts of a coalescing agent, 0.5-6 parts of a pigment, 20-40 parts of a filler, 5-25parts of distilled water I, 0.1-4 parts of a thickening agent and 0.1-4 parts of distilled water II. The water-based high-temperature-resistant coating for high-temperature coating has excellent waterresistance and salt spray resistance, can be directly applied to a high-temperature substrate in a coating manner, and can be directly used for treating some high-temperature parts which are in a high-temperature state for a long time due to special reasons without shutdown for cooling.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, and in particular relates to a water-based high-temperature-resistant coating for high-temperature coating and a preparation method thereof. Background technique [0002] Water-based high-temperature resistant coatings have been widely used in high-temperature equipment such as metallurgy, aviation, and electric power, as well as blast furnaces in steel mills, outer walls of hot blast stoves, high-temperature chimneys, flues, high-temperature hot gas pipelines, heating furnaces, and heat exchangers. However, due to some special reasons, some high-temperature parts will be in a high-temperature state for a long time. If these parts are painted, the equipment needs to be shut down and cooled first, which will cause irreversible damage to the equipment. Therefore, the coating construction of such equipment needs to be carried out under the high temperature state of the equipment, which ...
