Description
Technical field
The present invention relates to thermal insulation coatings technical field, specifically, a kind of nano ceramic high-temperature-resistant thermal-insulation coating relate to
And preparation method thereof.
Background technology
It is traditional insulation material, mostly porous discrete material, such as rock wool, mineral wool, perlite, polyurethane foam, light
Matter calcium carbonate etc., these materials make the molecular motion by warm-up movement be obstructed, and play insulation effect.But the transmission of heat, except
Outside solid heat transfer, also radiant heat transfer, radiant heat transfer is not influenceed by medium, and interface does not work yet.Temperature is higher, and radiation is got over
By force.Therefore the insulation of high temperature heat supply pipeline only considers that solid heat transfer is inadequate.
