The present invention also provides a kind of preparation methods of above-mentioned nano transparent insulating coating, comprising the following steps:
(1) preparation of nanometer titanium dioxide silica aerogel slurry:
The dispersant B, wetting dispersing agent, deionized water and nanometer titanium dioxide silica aerogel are taken, is mixed, adjusting pH value is 7.5~8.5, disperse on dispersion machine, be subsequently placed in grinder and grind, powder diameter receiving within the scope of 30~90nm is made Rice aerosil slurry;
(2) preparation of transparent heat insulating dope:
The nanometer titanium dioxide silica aerogel slurry that takes the water-based acrylic resin, deionized water, step (1) to obtain, point Powder A, defoaming agent, levelling agent, thickener, dipropylene glycol methyl ether and dipropylene, mixing, adjust pH value be 7.5~ 8.5, disperse on dispersion machine, be placed in grinder grind to get.
In wherein some embodiments, the jitter time in the step (1) is 15~20min, revolving speed 1150~ 1250rpm;Milling time is 2~3h, 2900~3100rpm of revolving speed.
In wherein some embodiments, jitter time in the step (2) is 15~20min, revolving speed is 1150~ 1250rpm;Milling time is 1~2h, and grinding rate is 2400~2600rpm.
The present invention is overcoming existing nano material difficulty to disperse technological difficulties easy to reunite, provide it is a kind of not only transparent but also every Heat, while preparation method is simple, it is easy for construction, it can be from a kind of well-illuminated insulating moulding coating of nanometer of dry low cost.
Heat transmission is by three kinds of conduction, convection current, radiation modes.Reach good heat-proof quality, it just must be to above-mentioned 3 Kind mode takes targeted measure.Air has the thermal coefficient of very little, if can try to make in solid containing a large amount of quiet Air only, then this solid will have good heat-proof quality.And aerogel material is due to the nanometer amount with space The hole of grade, grain skeleton is very very thin, and undoubtedly the gas heat-transfer of inside gentle for solid contact heat conductien all has very Big inhibition.That is aeroge is a kind of excellent ground thermal conducting material.
Nano-meter SiO_2 of the present invention2Aeroge has unique nanostructure, bore hole size and particle diameter range It is nanometer scale (1-100nm), and forms open nanometer porous structure and continuous three-dimensional net structure, height compare table Area (200~1000m2/ g), high porosity (80%~99.8%) and low-density (3~600kg/m3), make Nano-meter SiO_22Airsetting The network skeleton particle of glue reaches nanoscale and it has also reached nanometer scale in pore structure, thus makes aerogel material It is highly desirable nanocatalyst, adsorbent and catalyst carrier material with nanoscale and nano-pore structure double grading Material, catalytic activity and selectivity are significantly larger than conventional catalyst, and it also has excellent thermal stability, can be effectively The generation for reducing side reaction, prolongs the service life.
The present invention utilizes Nano-meter SiO_22Aeroge is to the selection characteristic of solar spectrum, with Nano-meter SiO_22Aeroge is main former Material, selection transparent resin are film forming matter, and the two and other auxiliary aids are mixed to prepare transparent heat insulating dope, are applied to building Glass surface, do not change the translucency of glass, can effectively shield infrared emanation and barrier ultraviolet light.Also have antistatic, Anti-dazzle inhibits the functions such as ultraviolet light irradiation destruction.Meanwhile coating of the present invention also reflects while guaranteeing visible light-transmissive Longer wavelengths of room heater heat radiation is conducive to heating effect and indoor heat is stopped to leak by glass door and window conduction, subtracts The loss of energy in few winter room, to reach the energy-saving effect of " cool in summer and warm in winter ".
Coating of the present invention uses Nano-meter SiO_22Aeroge is main functional stuffing, and heat-proof quality is excellent.It is a kind of reason The heat-insulation transparent material thought.The fields such as heat-insulated solar energy, solar heating, detector surface heat preservation can be widely used in, are made It is wide with range, and the requirement of environmental protection can be reached and improved the coating service life.
But polarity due to nano material itself and particle imperceptibility, there is great specific surface area and higher compare table Face energy, makes it be not easy to disperse in apolar medium, easy to reunite in polarizable medium, directly affects the performance of their performances, most The specific performance that nanoparticle has is lost when using eventually.The dispersion of general nano material is natively not easy, and reaches Easily reunite again after a period of time after certain dispersion effect, to make its performance that cannot fully play.And it is transparent heat-insulated Coating on 5-25 μm of coating thickness, need its good heat-proof quality just and can make its be coated on glass play well every Heat function.
The present inventor team is directed to Nano-meter SiO_22The particularity of aeroge in an aqueous medium, it is preferably most effective Dispersing agent is to Nano-meter SiO_22Aeroge carries out dispersion and surface is modified, further according to dispersing mode (mechanical stirring, grinding etc.), dispersion Influence of the factors such as dosage, pH value, nano material dosage of agent to the stability of nano material water slurry, determines most suitable Ideal nano silica slurry is made in dispersing technology and condition.
After above-mentioned nano silica slurry is made, inventor team further passes through the modified nano material point of research Technology of preparing and allied processes in water paint are dissipated, raw material appropriate and proportion is selected to improve the water-thinned nanometer paint Storage stability and contaminated resistance, analyze best formation condition of the modified nanoparticle slurry in water paint and right The affecting laws of coating properties determine its optimum addition, and nano transparent insulating coating of the present invention is finally made.
The present invention compared with the advantages of the prior art and has the beneficial effect that
(1) the nanometer titanium dioxide silica aerogel of single function admirable is added, and by preferred dispersants etc. to nanometer two Silica aerogel is modified, eliminate its it is easy to reunite be not easy the problem of dispersing, and preferably remaining raw material and proportion, technique step Suddenly, ideal nano transparent insulating coating, and save the cost and simplified construction technology is made in parameter etc..
(2) overcome existing heat reflection plated film general on the market, low reflection plated film or general nano transparent insulating coating There is heat-proof quality and not high or both performance of visible light transmittance is all undesirable, can make to be coated glass and reach well thoroughly Bright heat-proof quality.
(3) it bar spreader, wet film maker are either artificial can be used to brush, coated film is dried without heating It is dry, can self-curing from dry, people can be easy to use voluntarily to coat, simple process is convenient and easy.
(4) there is good environmental-friendly function, be free of solvent composition, it is nontoxic and pollution-free.
