Description
Technical field
The present invention relates to aeroge preparation technical fields, and in particular to a kind of normal pressure continous way prepare aeroge method and
Equipment.
Background technique
Aeroge is the novel nanometer of one kind, porous, low-density, amorphous material, has continuous three-dimensional net structure.
Aeroge has many unique properties, as high porosity, high-specific surface area, low-density, low heat conductivity, sound insulation value are excellent
Deng, have Magic Characteristics in numerous areas such as calorifics, optics, electricity, chemistry, have boundless application prospect.
Supercritical Drying Technology is that earliest realize prepares aeroge technology in batches, be have been relatively mature, and domestic at present
Outer aeroge enterprise uses more technology.But because supercritical pressure and temperature are all very high, as the super critical point of methanol exists
239.4 DEG C and 81 atm highers, in addition, supercritical autoclave cannot achieve full-automatic continuous production, it is necessary to make kettle
It opens, by hoisting material, aerogel products cannot achieve serialization conveying, therefore there are high-voltage high-temperature equipments to hold high for supercritical technology
The disadvantages of expensive, security risk is big, low efficiency, at high cost, complex process.Constant pressure and dry is a kind of novel aeroge preparation work
Skill is that current research is most active, the maximum aeroge of development potentiality batch production technology, for normal pressure technology is with respect to supercritical technology,
It is low with equipment investment, production cost is low, excellent product performance, it is safer, easy, be able to achieve the advantages such as continuous production, be
The trend of aeroge research and development and production.There are document and patent report constant pressure and dry to prepare aerogel products, but its method
Gel time is long, a large amount of organic solutions are introduced in colloidal sol, and modifying agent loss is caused to increase, and the cost recovery of alcohols also compared with
The disadvantages of height, it is cumbersome that there are methods, and the production cycle is long, low efficiency, increase the airtightness to equipment, explosion-proof, prevent it is quiet
The requirement such as electricity, increases cost and also reduces the safety of production.
Meanwhile integrating existing patented technology and document report, existing SiO2Airsetting glue production method mostly uses organic
Silicon (ethyl orthosilicate, methyl orthosilicate, multi-polysiloxane) is raw material, is prepared with supercritical drying or constant pressure and dry method.It is super
Critical methods can be divided into ethanol supercritical drying again and carbon dioxide supercritical extraction is dry, and the two raw material is organo-silicon ester,
The problems such as that there are raw materials is very expensive for these methods, and has toxicity, complex process, safety is low seriously constrains SiO2Airsetting
The large-scale production and application of glue.It can be using waterglass as waste SiO using non-pressure process production aeroge2Airsetting
Glue, hence it is evident that reduce the cost of raw material and the complexity of equipment, but aerosil produced using waterglass, often by
In a kind of ion exchange resin, so that silicate solution is made, then adding a kind of basic catalyst makes it at gel.Then hot water is used
Resulting gel is washed repeatedly, then SiO is made by normal pressure after organic solvent displacement and surface methyl groups Silanization reaction2Airsetting
Glue.It discloses in the patent application document that patent application publication number is CN102167337A with alkaline silicate (sodium metasilicate, silicic acid
Potassium) it is silicon source, water and ethylene glycol dilution is added, it is 2-4 that adjustment pH after inorganic acid sufficiently reacts 1-5 hours, which is then added, repeatedly
It is 0.1% hereinafter, finally being carried out at 100-400 DEG C fast with or mixtures thereof water or alcohol washing to sodium ion or potassium content
Speed dehydration and drying.Such method is cumbersome, and the production cycle is long, low efficiency, and it is useless that a large amount of saliferous can be generated in preparation process
Water.In addition after gel-forming by the way of solvent displacement, ethyl alcohol is added in silica solution, alcogel is directly made, in gel
Gel obtained by the alcohol solution dipping with various concentration is still needed to afterwards.Since technical process is band alcohol band chlorine, so equipment durability
It is very high with the requirement to equipment liner.
The equipment used for the most of existing aeroge of alcohol-containing containing chlorine production, in order to guarantee that production security needs are being set
Liner is set in standby shell, and has limitation requirement for accelerated mode, is adopted similar to this accelerated mode of radio-frequency radiation
Used time will generate sparking burning or even explosion, have biggish production hidden danger.
