Description
Technical field：
The present invention relates to a kind of Performances of Novel Nano-Porous meter level micropore heat-barrier materials and preparation method thereof, belong to high temperature insulating material field.
Background technique：
The relatively good heat-insulating heat-preserving material of existing heat-proof quality is adopted such as ceramic fibre, calcium silicate board with microporous and lightweight thermal insulation brick
Made of micron order fire resisting powder or micron order fiber, between 2~10 microns, thermal coefficient exists the stomata of material
Be 0.12~0.15W/mK at 600 DEG C, still, in the occasion for needing more preferable heat-proof quality, above-mentioned common heat-barrier material every
What hot property was still difficult to meet the requirements.
Popular a kind of nanometer level microporous heat-barrier material currently on the market, using nanometer level microporous SiO 2 powder such as gas
Aerosil nanometer powder and/or aerosil nanopowder are primary raw material, the nanoparticle of primary silica
Sub- diameter is 7~10 rans, is received by the aggregate stomata that this silica nanometer grade micropore powder is formed 20~30
Rice leads to the solid conduction heat transfer very little of this material in this way.Meanwhile it joined again in this nanometer level microporous heat-barrier material
The fire resisting powder additive of anti-infrared-ray resistant to high temperature, so that the infrared radiation heat transfer of heat-barrier material also falls below very low water
On flat.Micron-sized reinforcing fiber is added, the plate-like heat-barrier material with the micro- stomata of nanoscale, thermally conductive system are pressed into
Number is 0.022~0.035W/mK at 600 DEG C, and the heat-proof quality of this nanometer level microporous heat-barrier material is than micron order stomata
Ceramic fibre and 3~4 times of calcium silicate board or more, solve many insulation requirements to space and thickness requirement harshness occasion,
It is a kind of extraordinary nanometer level microporous heat-barrier material.
But above-mentioned nanometer level microporous heat-barrier material also has its shortcoming, firstly, this nanometer level microporous heat-insulated material
Material cannot resist destruction of the liquid of water etc to the micro- stomata of nanoscale, because this nanometer level microporous heat-barrier material is meeting with
After by water and liquid infiltration, in water and liquid drying and volatilizing again, due to the systolic pressure of the surface tension of water and liquid
Effect is macroscopically being formed so that the micro- pores collapse of nanoscale destroys and is increased to micron order even millimetre-sized hole
Many perforation stomatas and crack, the excellent thermal insulation performance for the nanometer level microporous heat-barrier material that thoroughly scattered and disappeared.General solution party
Method is to add additional waterproofing agent in this nanometer level microporous heat-barrier material or the nanometer level microporous heat-barrier material of aeroge,
It can be applied to the more occasion of moisture, for example as in the backing heat-barrier material application of castable refractory.Due to this
Waterproofing agent is the hydrophobic membrane that organic-based material is formed on nanometer level microporous material powder surface, so that nanometer level microporous heat-barrier material
With excellent hydrophobic effect, to have the destruction for preventing water and liquid to the micro- stomata of material nano grade.But it dredges
Organic waterproof when the heat-barrier material of water is once exposed in 300~500 DEG C or more high temperature, in nanometer level microporous heat-barrier material
By after complete burn off, heat-barrier material has just scattered and disappeared hydrophobic effect for agent, this nanometer level microporous heat-barrier material encounter again water or
When liquid infiltration, the systolic pressure that the micro- stomata of nanoscale will be formed by the surface tension of liquid is destroyed, and leads to this kind of nanometer
The heat-proof quality sharp fall of grade micropore heat-barrier material, it is serious that material is caused a large amount of crack and contraction macroscopically occur,
Heat-barrier material is caused to destroy the global failure of even refractory lining.
The waterproof solution of next is to add heat shrinkage film, package plastic foil outside nanometer level microporous heat-barrier material or dredge
The waterproof protective layer of water material etc, to reach waterproof action.But it in heat-barrier material transports and carries and construct, can not keep away
There is friction destruction effect to the heat shrinkage film of outer layer, plastic foil or waterproof protective layer with exempting from, it is easy to lead to the office of waterproof layer
Portion is damaged, is repaired even if temporarily pasting adhesive tape in breakage, and also inevitably there is the gap of leak place, water and liquid
Body or it is readily permeable enter, cause the micro- stomata of the nanoscale of heat-barrier material to be deteriorated；Even if the waterproof layers such as plastic foil are protected
It is good, there is not water leakage situation, same reason, the waterproof layers such as this kind of plastic foil are used above at 300~500 DEG C of high temperature
Afterwards, the waterproof layers such as plastic foil shrink carbonization and decompose, and expose protected nanometer level microporous heat-barrier material, in this way when having again
When moisture or liquid immerse heat-barrier material, the micro- stomata of the nanoscale of nanometer level microporous heat-barrier material is still easily broken
Fall, thus its excellent heat-proof quality of scattering and disappearing.Finally, this kind of use nano grade gas phase silicon dioxide powder or silica gas
Gel nanometer powder is nanometer level microporous heat-barrier material made of primary raw material, since the cost of both raw materials is very high, no
It is promoted and applied conducive to a large amount of.
The present invention uses a kind of new formulation and manufacture craft, and raw material used in the formula and manufacture craft are sub-micron
Grade poromerics powder and nanometer level microporous material powder are compound, the submicron order poromerics powder particle diameter as main body
In 0.05~0.5 micron i.e. 50~500 nanometer ranges, it is micro- that novel nanoscale is together constituted with nanometer level microporous material powder
Hole heat-barrier material.This Performances of Novel Nano-Porous meter level micropore heat-barrier material is after 350~950 DEG C of high-temperature heat treatment, sub-micron
Grade micropore powder and nanometer level microporous material powder are sintered to form firm Ceramic bond, the nano micropore structure being consequently formed
Heat-barrier material water or liquid leaching pool when, the micro- stomata of nanoscale can resist the systolic pressure of the surface tension of water and liquid
Power effect keeps nanoscale micro-pore structure to stablize constant, so that not afraid of water and liquid dipping destruction is provided with, in water
After drying again with liquid, heat-proof quality is unaffected, solves Conventional nano grade micropore heat-barrier material and aeroge at one stroke
Nanometer level microporous heat-barrier material meets the problem of water destruct.
The heat-proof quality of this Performances of Novel Nano-Porous meter level micropore heat-barrier material is than traditional micro-ceramic fiber and calcium silicate board
It is better 2~2.5 times, can satisfy many advanced insulation requirements, while can be applied to field existing for a large amount of water and liquid again
In conjunction, by Performances of Novel Nano-Porous meter level micropore heat-barrier material made of this formula, main component be submicron silica powder powder i.e.
Commercial ultrafine silicon ash, cost are lower very than nanometer level microporous fumed silica powder and nanometer level microporous aerogel powder
