Description
Technical field
The invention belongs to the super insulating material field, be specifically related to prepare the method for the silica aerogel of doping brucite fiber and titania powder.
Background technology
Aerogel is coalescently to form the nanoporous reticulated structure by colloidal particle or high-polymer molecular are mutual, and is full of a kind of high dispersive solid-state material of gaseous state dispersion medium in hole, its solid mutually and pore texture be nanometer scale.It is a kind of novel nanometer, porous, low density, amorphous material, has the continuous three-dimensional network structure, and typical network diameter is nano level, because its translucent color and extra light weight also are known as " solid-state cigarette " sometimes.This material seems fragile can't bear, but because its nanoporous network structure has effectively suppressed solid-state, gaseous state and radiation thermal conduction, in fact very sturdy and durable, high energy bears 1400 ℃ high temperature, it is the heat insulation heat insulation material of a kind of efficient lightweight nanoporous, its specific refractory power is also very low in addition, and heat insulation capacity also is eager to excel 39 times than best glass fibre.Its structural uniqueness shows a lot of unique character of aerogel and tempting application prospect, has caused chemist, physicist, material scholar's etc. great attention.It shows good using value in fields such as calorifics, optics, electricity, acoustics, mechanics and fractal, in application facet, it has been applied to Cerenkov detector, specific acoustic resistance coupling material, catalyzer and carrier, high efficiency heat insulation material and has prepared efficient rechargeable cell etc.All used SiO on Russia " peace " number space station and the U.S. " Mars Pathfinder " detector
2Aerogel.
Single aerosil is because of some defectives of its existence, and as poor toughness, more crisp, intensity is low, frangible, and has an infrared transparent during high temperature, and the unmodified aerogel easily hydrophilic gel that causes subsides, limited its practical value.The present invention prepares the fiber reinforcement type aerogel, can improve 2～30 times of intensity, moreover also can improve its toughness.This fiber is an environmental protection fiber, is unique not carcinogenic fiber.And the fusing point height can be high temperature resistant.For reducing the thermal conductivity titania-doped ultra-micro powder of aerogel when the high temperature as opalizer, with blocks infrared radiation.Carry out hydrophobically modified at last, make the surface hydrophilic base become hydrophobic group and reach hydrophobic effect, by the above effort use value of enhanced aerogel greatly.What the present invention selected for use is that nontoxic, cheap industry silicasol is the silicon source, can reduce production costs greatly.Non-pressure process is difficult to prepare the low-density aerogel of flawless, and the employing supercritical process can be prepared and not ftracture, the well behaved aerogel block body of flawless.(reference M Gronauer, J Fricke.Acoustic properties of microporous SiO
