Method.
Technical background
The utilization efficiency that unnecessary heat transfer results in energy under various environment reduces, and increases the additional energy and disappears
Consumption.In building field, traditional external wall insulation is mostly based on styrofoam, although having lower thermal coefficient, heat-proof quality
It is excellent, but levels of audit quality is uneven in the market, and needs special mounting process, since insulation board is by adhesive in wall
Body is adhered to one, and as time increases, Organic adhesive aging causes falling for external wall insulation large area, exist compared with
Big security risk.
In industrial circle, high-temperature service, especially jet chimney, dyeing apparatus etc., due to it is most of do not do it is special
Isothermal holding, surface temperature are mostly higher than 150 DEG C, not only cause the huge waste of the energy, but also workers with long time near work,
Especially during the broiling summer, worker's dress is thiner, it is easy to worker be caused to scald.
Nanometer titanium dioxide silica aerogel is a kind of novel light nanoporous material, has low-density, high porosity, low
The features such as refractive index and low-thermal conductivity.The unique nanoporous network structure of aerosil makes it have excellent guarantor
Warm heat-proof quality, aerosil are a kind of new materials with nano-porous structure, be it is most light in the world at present, every
The best solid insulating material of hot property.With three-dimensional net structure, with up to 90% or more porosity, nanometer titanium dioxide
The thermal conductivity of silica aerogel consists of three parts: gas thermal conductivity, solid-state thermal conductivity, radiant heat conductanc.Air molecule is averaged
Free layer is in 70mn or so, and the pore size of nanometer titanium dioxide silica aerogel is 20-50nm, is much smaller than this critical dimension,
Material internal eliminates the need for convection current, and gas thermal conductivity is just very low；And lower density limits office of the heat in sparse skeleton again
It propagates in portion.
Summary of the invention
For either building field or industrial circle currently on the market, some problems existing for Conventional insulation,
This patent discloses a kind of aerogel heat-insulating thermal insulation coatings and preparation method thereof, select inside current inorganic porous solids material most
Light nanometer titanium dioxide silica aerogel as functional heat-barrier material, using the special three-dimensional net structure of nano silica and
The form of construction work of spraying or blade coating can be used so that coating has the thermal coefficient of polar region in lower pore size, has preferable
Adiabatic heat insulating effect.
Coating prepared by the invention patent, thermal coefficient is extremely low, generally only needs 1-5mm that is, conventional vacuum rock wool
The heat insulation effect of 10-50cm, in building field, especially in summer sweltering heat, winter sombre south can be applied to interior wall or outer
Wall has the effect of heat insulation decoration integrated；In industrial circle, especially jet chimney or dyeing apparatus, due to by character and sky
Between limit, do not use traditional thicker thermal insulation material generally, and be chronically in the environment of high temperature and humidity, corrosion of metal is phase
When serious, the coating of invention, high-efficiency rust-preventive pigment is added, there is good anti-corrosion effect, and surface hydrophobicity, Yi Qing
