Description
Technical field
The present invention relates to aeroge preparation technical fields, and in particular to a kind of equipment that normal pressure continous way prepares aeroge.
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.

The large-scale production and application of silica aerogel.It can be using waterglass as waste using non-pressure process production aeroge
Aerosil, hence it is evident that reduce the cost of raw material and the complexity of equipment, but silica gas is produced using waterglass
Gel so that silicate solution be made, then adds a kind of basic catalyst and makes its Cheng Ning often by means of a kind of ion exchange resin
Glue.Then it washs resulting gel repeatedly with hot water, then passes through normal pressure after organic solvent displacement and surface methyl groups Silanization reaction
Aerosil is made.It discloses in the patent application document that patent application publication number is CN102167337A with alkaline silicon
Hydrochlorate (sodium metasilicate, potassium silicate) is silicon source, and water and ethylene glycol dilution is added, after then addition inorganic acid sufficiently reacts 1-5 hours
Adjustment pH is 2-4, is repeatedly 0.1% hereinafter, finally existing with or mixtures thereof water or alcohol washing to sodium ion or potassium content
Quick dewatering drying is carried out at 100-400 DEG C.Such method is cumbersome, and the production cycle is long, low efficiency, and meeting in preparation process
Generate a large amount of brine waste.In addition after gel-forming by the way of solvent displacement, it is direct that ethyl alcohol is added in silica solution
Alcogel is made, gel obtained by the alcohol solution dipping with various concentration is still needed to after gel.Since technical process is band alcohol band
Chlorine, so equipment durability and requirement to equipment liner are very high.
For the most of existing aeroge of alcohol-containing containing chlorine production technology, in order to guarantee that production security is needed to accelerated mode
It is limited, and has limitation requirement for the material of transmission device, be similar to this accelerated mode of radio-frequency radiation and use
When will generate sparking burning so that explosion, have biggish production hidden danger.
