In the following embodiments, micrometer silicon carbide silicon whiskerettes composite based on fullerene-based material will be carried out comprehensively
Introduction.
First the constituent of micrometer silicon carbide silicon whiskerettes composite based on fullerene-based material is introduced.
() fullerene C60。
() carborundum, a length of 1 μm 20 μm, its surface is transformed through wet etching.
(iii) etching composite, a length of 1 μm-20 μm, surface is etched.
() Kaolin, through prodan (Na2SiF6) process.Kaolinic purity can reach 99.99%.
Composite described in the present embodiment includes fullerene C60With a combination, described compositions is: () is with through hexafluosilicic acid
Sodium (Na2SiF6) Kaolin that processed.Prodan is a kind of low cost and the white crystals powder being usually used in being fluorinated urban water supply
End.During silicon carbide, the Kaolin processed with prodan is used as admixture and the fluorine source of direct perfluorocarbon SiClx.In advance
Etching composite is used as rapid scattered mixing agent.() uses Na2SiF6The Kaolin processed and tetrafluoroethene or polytetrafluoro
Ethylene (C2F4Or C2F4) etc. for generate composite reaction create one " activated material ".(iii) carborundum, a length of 1
μm 20 μm, its surface is transformed through wet etching.
Especially, Kaolin guarantees that any direct fluorinated material used subsequently is (such as politef (PTFE) or tetrafluoro
Ethylene (TFE)) thoroughly decompose and dispersion.During manufacture, Na is passed through in the directly fluorination of carborundum2SiF6Start, so that manufacturing
Process costs is relatively low.Additionally, the composite after pre-etched adds structure and the thermal mass of resulting composition, and the most true
Decomposition completely and the dispersion of fluorinated material are protected.
Especially, micrometer silicon carbide silicon whiskerettes composite based on fullerene-based material of the present invention except have with not
Come stone whiskerettes, β Sialons, aluminium oxide and the mechanically and thermally performance of carborundum, also there is C60It is distinctive for fullerene-based material
Pliability and the strongest hardness.Such as, composite disclosed in this invention can join epoxy resin/microsphere matrices painting
In material, foamed materials and equipment, required mechanical performance and hot property can be improved, and do not significantly change the proportion of host material
Or other properties.And the compositions with special ratios can also be more efficiently used for some special-purposes.
The method of preparing micrometer silicon carbide silicon whiskerettes composite of based on fullerene-based material is described below, including:
C60Prewet carborundum with the Fluohydric acid. (BHF) using dilution.
The C that BHF prewets60Directly mix with the composite being fluorinated with carborundum.In fluorination process, by dry Kaolin and
Na2SiF6As fluorinated material, admixture, and can mix with under direct fluorinated source at low temperatures.Equally, PTFE or
TFE can also add as the direct fluorization agent supplemented or increase newly.
Preparation method normally also includes processes this mixture at 800 DEG C-850 DEG C.Firing equipment includes but not limited to make
With fluidized bed dryer or conveyer baking oven or rotary kiln or calcining furnace or ceramics furnace.
Composite set forth herein and production method are compared with having some advantage for known synthetic and method.
Its advantage includes but not limited to following:
(1) process time is relatively short, it is ensured that its most continuous substantial amounts of production.
(2) material prepared by is prone to uniformly be combined with other materials, such as, can be prepared as microsphere filled compound
In foam plastics.
Multiple by using the activated material of pretreatment can realize this micrometer silicon carbide silicon whiskerettes based on fullerene-based material
The quick production of condensation material.Usually, activated material can include pre-etched composite, Na2SiF6The Kaolin processed is with direct
Fluorinated material.Activated material typically can mix rapidly with carborundum, and can be at high temperature and concentration nitrogen-air-fluohydric acid gas
Atmosphere in quickly process.Especially, heating kaolinite (Al2Si2O5(OH)4) produce metakaolin from room temperature to about 750 DEG C
(2Al2Si2O7+4H2O), this is owing to starting endothermic decomposition at about 600 DEG C, and this stage can produce a kind of material and become
Gamma aluminium oxide (Si3Al4O12+SiO2).This process was usually used in producing in the pastβSiAlONS, and can now be used for producing and do not come
Stone whiskerettes.
Activated material (Kaolin, PTFE or TFE) can be generated the arbitrary orthogonal shape of length with the carborundum mixing being dried
Silicon carbide microcrystalline palpus.Just these features and this micrometer silicon carbide silicon whiskerettes composite based on fullerene-based material is produced
The calorifics of various materials and the enhancing of mechanical performance, such as, syntactic foam can be applied in the engineering of deep-sea, makees
Applying at deep seafloor for novel heat insulation insulant, petroleum pipeline is exposed to seabed metal part protection, performance can show by ratio
Silicon materials excellent and cheap.Similar feature, the especially length of random distribution so that the mechanical strength of material
Strengthen, such as vinyl esters, gel coating, the material such as cast polyurethane, main precisely due to the random distribution of admixture length
And its performance is improved.
Processes disclosed herein can be carried out at a lower temperature, because Na2SiF6The temperature beginning paying out gas is
