Abstract
Provided is a hydrophobic silica aerogel heat insulation board. The hydrophobic silica aerogel heat insulation board is made of silica aerogel composite materials. The hydrophobic silica aerogel heat insulation board comprises a baseboard and silica aerogel, wherein the baseboard is made of material of a porous structure, and the silica aerogel is adsorbed in holes or hole walls of the baseboard. The outer layer of the heat insulation board is more than one reflection layer, more than one silica aerogel composite material heat insulation layer are arranged under the reflection layers, and the heat insulation layer are made of rigid materials. The reflection layers arranged outside the heat insulation layer can further improve heat insulation effect of the heat insulation board, have waterproof effect and improve use stability of the heat insulation material. Meanwhile, the phenomenon that particles of the silica aerogel material fall off in the process of use can be reduced. With the technical scheme, the hydrophobic silica aerogel heat insulation board is beneficial for practical use, good in performance and capable of meeting market demands.
Description
Technical field
The utility model belongs to field of heat insulating materials, particularly a kind of aerosil heat insulating material, and this heat insulating thermal preserving board has a reflector layer.
Background technology
The core of China's building energy conservation is that buildings exterior-protected structure and heating system are reformed, and wherein the wall thermal insulating construction technology is being brought into play more and more important effect in building energy conservation.Society, developed country all payes attention to power saving beyond example.The present unit building area heating energy consumption of China is to be equivalent to 3～4 times of the close developed country of weather conditions.China is a country that the energy is barrenr, therefore, reasonable energy utilization, improving energy utilization rate is the task of paramount importance of Chinese society development, and the improvement of skin space enclosing structure power-saving technology, the renewal of heat insulating material has earth shaking meaning to the reduction of society and building energy consumption.
Aeroge is that with the dried product of gel internal solvent, it is a kind of amorphous state low density material with nano-porous structure in the situation that keeps the gel skeleton structural integrity.Aerosil is known as again " blue smoke ", " solid cigarette ", is present the lightest known solid material, also is heat-insulating property best material up to now, is described as " the magical material that changes the world ".The aerosil heat insulating material is made as material of main part take aerosil, has that coefficient of thermal conductivity is low, density is little, intensity is high, space availability ratio is high, a superior function such as sound insulation, environmental protection, waterproof are not fired.
Because the aerosil yardstick is the porous material less than 50 nanometers, the diameter in hole is less than the mean free path of molecule, when aerosil during as thermal insulation material, the heat conduction of gas greatly reduces, thermal conductivity is also lower than air, and thermal conductivity at normal temperatures is 0.015 to 0.02W/mK.But aerosil is because its intensity is low, fragility is large, therefore application on engineering is subject to a lot of restrictions, need to strengthen aeroge toughness reinforcingly, makes it be suitable for using, therefore the development of the composite material of aerosil is very fast, comprising rigidity and flexible composite material.In the process of using, the phenomenon of particle, dust releasing can appear in aerosil, environment is impacted, so in the process of using, this problem should be properly settled.
The utility model content
The purpose of this utility model has increased reflector layer for a kind of hydrophobic silicon dioxide aerogel heat insulating thermal preserving board is provided in the outside of insulation layer, can further improve the insulation effect of warming plate; Reflector layer has also played the effect of waterproof, water proof, has improved the stability in use of this kind heat insulating material, has reduced simultaneously the problem of particle detachment in the silica aerogel material use procedure.The aerosil warming plate of this technology preparation more is conducive to practical application, and function admirable is met the need of market.
For achieving the above object, the utility model has adopted following technical scheme.
A kind of hydrophobic silicon dioxide aerogel heat insulating thermal preserving board is comprised of silicon dioxide silica aerogel composite material, comprises substrate and aerosil, and substrate is the material of loose structure, and aerosil is adsorbed in the hole of substrate or on the hole wall.
A kind of hydrophobic silicon dioxide aerogel heat insulating thermal preserving board, the skin of this heat insulating thermal preserving board are the above reflector layer of one deck, and the following of reflector layer is the composite material thermal insulation layer of the above aerosil of one deck, and this heat insulation layer is rigid material.
In the utility model, the external surface of described reflector layer and aerosil heat insulation layer is wrapped in one deck plastic foil.
The preferred version of present technique is that described reflector layer is aluminium foil.
The preferred version of present technique is, described aerosil heat insulation layer thickness be 5～30mm.
The preferred version of present technique is that described outer field plastic foil is attached to reflector layer, aerogel layer surface by the method for thermoplastic.
The preferred version of present technique is that the composite material of described aerosil is the compound of aerosil and glass fiber.
In the technical program with the outside of the reflector layer more than one deck as for the aerosil heat insulation layer, played the effect of reflective cooling, and preferred aluminium foil is as the reflector layer material, the absorptivity of its light radiation heat is minimum, can effectively reduce the surface temperature of heat insulation layer, thereby improve the effect of heat insulation layer; And this reflector layer has played the effect that prevents the aerosil particle detachment equally; The effect that simultaneously also has water proofing property, aluminium foil is covered with in the external surface of aerosil heat insulation layer, has intercepted contacting of aeroge and moisture, thereby has improved waterproof, the water resistance of aerogel material, has improved the stability in its use procedure; In preferred version, method with thermoplastic is wrapped up one deck plastic foil at the external surface of reflector layer and heat insulation layer, this plastic foil has stopped that further dust, the particle of aerosil fly away in ambient air, have improved the safety in utilization of aerosil.
