Description
Technical field
The present invention relates to a kind of coating, relate in particular to a kind of nano ceramic high-temperature-resistant thermal-insulation coating and preparation method thereof, belong to field of heat insulating materials.
Background technology
Traditional lagging material mostly is the porousness loose material, and as rock wool, glass wool, perlite, polyurethane foam, light calcium carbonate etc., these materials make and be obstructed by the molecular motion of thermal motion, play insulation effect.Yet the transmission of heat except solid heat transfer, also has radiative transfer, and radiative transfer is not subjected to the influence of medium, and the interface is also inoperative.Temperature is high more, and radiation is strong more.Therefore the insulation of high temperature (200～600 ℃) heat supply pipeline only considers that solid heat transfer is not enough.
Temperature after the insulation of national regulation heat insulating work is less than 50 ℃, producer often requires to be incubated the back temperature and reaches in 45 ℃, tradition lagging material heat insulation function is incomplete, reach very thick that required standard does, in the pipe during 200～600 ℃ of temperature, thickness 12cm～25cm is many with material, the waste fund causes constructional difficulties.
Tradition lagging material, water-intake rate is very high, surpasses 200%, and a large amount of moisture absorptions or suction add high temperature, the efflorescence of part material, and the carbonization that also has, because water heat conduction, lagging material lost efficacy.In order to solve waterproof, traditional practice is to overlap a steel pipe again in the lagging material outside, is called " steel bushing steel ", for example, temperature is 350 ℃ in the heat supply pipeline of Φ 720,40 ℃ of insulation back temperature, lagging material thickness 20cm, outer steel pipe diameter 1.12m, the most direct consequence of bringing thus is that cost rises significantly, cause production cost high, weight increasing/weight causes constructional difficulties.
