The present invention is in the technological difficulties overcoming the dispersion of existing nano material difficulty easily to reunite, it is provided that one is not only transparent but also heat insulation, and preparation method is simple simultaneously, easy construction, can from the well-illuminated insulating moulding coating of one nanometer of dry low cost。
Heat transmission is by conduction, convection current, three kinds of modes of radiation。Reach good heat-proof quality, be necessary for above-mentioned 3 kinds of modes are taked measure targetedly。Air has only small heat conductivity, if can manage to make in solid containing air static in a large number, then this solid will have good heat-proof quality。And aerogel material is owing to having the hole of the nanometer scale in space, grain skeleton is very very thin, and the gas heat-transfer for the gentle inside of the contact heat conductien of solid-state all has very big inhibition undoubtedly。That is aeroge is a kind of excellent ground thermal conducting material。
Nano-meter SiO_2 of the present invention2Aeroge has the nanostructured of uniqueness, and bore hole size and particle diameter range are nanometer scale (1-100nm), and form open nanometer porous structure and continuous print three-dimensional net structure, its high-specific surface area (200~1000m2/ g), high porosity (80%~99.8%) and low-density (3~600kg/m3), make Nano-meter SiO_22The network skeleton granule of aeroge reaches nanoscale and it has also reached nanometer scale in pore structure, aerogel material is thus made to have nanoscale and nano-pore structure double grading, it is highly desirable nanocatalyst, adsorbent and catalyst carrier material, its catalysis activity and selectivity is significantly larger than conventional catalyst, and it also has excellent heat stability, the generation of side reaction can be efficiently reduced, increase the service life。
The present invention utilizes Nano-meter SiO_22The aeroge selectivity characteristic to solar spectrum, with Nano-meter SiO_22Aeroge is primary raw material, and selection transparent resin is film forming matter, the two is mixed with other auxiliary aid prepared transparent heat insulating dope, is applied to the glass surface of building, does not change the light transmission of glass, can effectively shield infrared emanation and intercept ultraviolet。Also there is the functions such as antistatic, anti-dazzle, suppression ultraviolet radiation destruction。Simultaneously, coating of the present invention, while ensureing visible light-transmissive, goes back the room heater heat radiation that reflection wavelength is longer, is conducive to heating effect and stops that indoor heat is leaked by glass door and window conduction, reduce the loss of indoor energy in winter, to reach the energy-saving effect of " cool in summer and warm in winter "。
Coating of the present invention adopts Nano-meter SiO_22Aeroge is major function filler, and its heat-proof quality is excellent。It is a kind of desirably heat-insulation transparent material。The fields such as solar energy is heat insulation, solar heating, detector surface insulation can be widely used in, use scope wide, and the requirement of environmental protection can be reached and improve the coating life-span。
But polarity and the granule granular due to nano material itself, there is great specific surface area and higher specific surface energy, it is made not easily to disperse in apolar medium, polarizable medium is easily reunited, directly affect the performance of they performances, during final utilization, lose the specific performance that nanoparticle possesses。The dispersion of general nano material is natively not easy, and very easily reunites after a period of time after reaching certain dispersion effect, so that its performance can not get fully playing。And transparent heat insulating dope is on the coating thickness of 5-25 μm, it is necessary to its good heat-proof quality just can make it be coated on glass and play good heat insulating function。
The present inventor team is for Nano-meter SiO_22Aeroge particularity in an aqueous medium, it is preferable that maximally effective dispersant is to Nano-meter SiO_22Aeroge carries out disperseing and surface modification, further according to factor impacts on the stability of nano material water slurry such as dispersing mode (mechanical agitation, grinding etc.), the consumption of dispersant, pH value, nano material consumptions, determine most suitable dispersing technology and condition, prepare desirable nano silicon slurry。
After preparing above-mentioned nano silicon slurry, inventor team is scattered in the technology of preparing in water paint and allied processes by the modified nano material of research further, suitable raw material and proportioning is selected to improve bin stability and the contaminated resistance of this water-thinned nanometer paint, analyze the modified nanoparticle slurry best formation condition in water paint and the affecting laws to coating properties, determine its optimum addition, finally prepare nano transparent insulating coating of the present invention。
The advantage of hinge structure of the present invention and having the beneficial effect that
(1) the nanometer titanium dioxide silica aerogel of single function admirable is added, and by preferred dispersants etc., nanometer titanium dioxide silica aerogel is modified, eliminate its not easily scattered problem of easily reuniting, and preferably all the other raw materials and proportioning, processing step, parameter etc., prepare desirable nano transparent insulating coating, and save cost and simplify construction technology。
(2) existing general heat reflection plated film on the market, low reflection plated film or general nano transparent insulating coating is overcome to have a heat-proof quality and visible light transmissivity is not high or both performances are all undesirable, it is possible to make to be applied glass and reach good transparent heat-insulated performance。
(3) bar spreader, wet film preparing device can be used or manually brush, coated film, it is not necessary to heating, drying, can certainly do by self-curing, be easy to use people and be coated with voluntarily, technique is simple, convenient and easy。
(4) there is good environmental friendliness function, without solvent composition, nontoxic pollution-free。
