Problems solved by technology

However, the temperature resistance of the publicly reported thermal insulation coatings is not high enough, generally lower than 600 ° C, so it can only be used in the field of medium and low temperatures
At present, although there are many coatings in the prior art, most of them only have a single performance index that has reached a relatively high level, and the comprehensive performance index is still difficult to meet the requirements of high-temperature environments in the fields of machinery, construction, and aerospace.

Abstract

The invention discloses a heat insulating coating and a preparation method thereof. The heat insulating coating is prepared from hydroxyethyl methylacrylate, hexamethyl cyclotrisiloxane, titanium dioxide, carbon fiber, hydroxyethyl cellulose, sodium silicate, filler, curing agent, solvent, dispersant, propanediol and silicon carbide. The preparation method comprises the steps that hydroxyethyl methylacrylate and hexamethyl cyclotrisiloxane are mixed in proportion and added into the solvent for stirring to be uniform; titanium dioxide and carbon fiber are added to be mixed thoroughly and evenly, then the dispersant is added, and hydroxyethyl cellulose and the filler are added as stirring is conducted, and mixed evenly; then sodium silicate is added for stirring to be uniform again; silicon carbide is added in propanediol, stirred uniformly and then added into the mixture; finally the curing agent is added for stirring to be uniform, and the heat insulating coating is obtained. The heat insulating coating is resistant to high temperature, low in density, strong in bonding power and impact resistance, excellent in combination property and can meet stringent requirements in the fields such as machinery, building and aviation.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a heat-insulating coating and a preparation method thereof. Background technique [0002] At present, thermal insulation coatings have been widely used in building exterior walls and roofs, industrial storage tanks and oil pipelines, and have achieved certain energy-saving effects. However, the temperature resistance of the publicly reported thermal insulation coatings is not high enough, generally lower than 600°C, so they can only be used in the medium and low temperature fields. At present, although there are many coatings in the prior art, most of them only have a single performance index that has reached a relatively high level, and the comprehensive performance index is still difficult to meet the requirements of high-temperature environments in the fields of machinery, construction, and aerospace. Disadvantages of low temperature resistance, low strength and poor adhesi...
