Description
Technical field
The invention belongs to the application of nano composite material in energy field, particularly relate to the application of nano composite material aspect save energy.
Background technology
Thermal insulating coating is a kind of coating that is applied over building surface, and it can effectively reduce building surface and temperature inside.In recent years, along with the popularization of building energy conservation, thermal insulating coating more and more is subjected to people's attention because of advantages such as economic, convenient and good heat-insulation effect.Thermal insulating coating is divided into isolation-type thermal insulating coating, reflection type thermal insulation coating and radiation type heat-insulation coating three classes according to the difference of heat insulation mechanism and heat insulation mode.The heat-insulating efficiency of reflection type thermal insulation coating is determined that by reflected sunlight (mainly being the near infrared ray with heat effect) therefore, the functional materials that development, production have high-reflectivity is the key that realizes the reflective thermal insulating coating of superperformance.
Summary of the invention
The objective of the invention is to overcome the deficiency that existing reflection type thermal insulation coating exists, a kind of sun screen and heat insulation nano composite material for reflecting infrared that near infrared light (sunlight) is had high-reflectivity is provided.
To achieve these goals, the present invention adopts following technical scheme:
A kind of sun screen and heat insulation nano composite material for reflecting infrared is made up of nano silicon and nano titanium oxide, and its weight ratio is 0.8:1~3:1.
The preparation method of above-mentioned sun-proof heat insulation nano composite material comprises the steps:
(1) the pH value scope of the adjusting nano silicon water-sol is 4~5.5;
(2) be that to be dispersed in mass concentration be in 6%~15% the nano silicon hydro-colloid for 3%~10% nanometer titanium tetrachloride solution with mass concentration; The volume ratio of nanometer titanium tetrachloride solution and nano silicon hydro-colloid is 0.8~1:1.8~2.5;
(3) the adding mass concentration is 1%~3% aqueous solution of urea, and control reaction temperature is 9~11 ℃, carries out original position and coats hydrolysis reaction, filters; The amount of aqueous solution of urea need not limit especially, and in right amount just, its effect is a deposition.
(4) microwave heating obtains sun screen and heat insulation nano composite material for reflecting infrared.
Compared with prior art, the present invention adopts following beneficial effect: the nano composite material that the present invention makes has high-reflectivity near infrared light (sunlight), sunlight had the heat insulation sun effect, can be used to prepare reflection type thermal insulation coating, can be applicable to outer wall heat-insulating coating, reach the energy-conservation effect of building materials.
Embodiment
The preparation method of sun-proof heat insulation nano composite material: with magnetic stirring apparatus and ultrasonic disperser nano silicon being dispersed in the water, being made into mass concentration and being 10% nano silicon hydro-colloid, is 5 with the vinegar acid for adjusting pH value; In water-bath, obtain mass concentration and be 6% nanometer titanium tetrachloride aqueous solution, and this nanometer titanium tetrachloride solution is joined (volume ratio of the nanometer titanium tetrachloride solution and the nano silicon water-sol is 1:2) in the nano silicon water-sol lentamente; Add a small amount of mass concentration and be 3% aqueous solution of urea, 10 ℃ of control reaction temperature are used slowly original position and are coated hydrolysis reaction and obtain gel precipitate, wash then, filter; For preventing the particulate secondary crystal and grow up that applied microwave adds quick heating, obtain the having nanometer silica-titania matrix material of (nuclear-coated).Use the near-infrared reflection performance that the near-infrared reflection instrument can record prepared matrix material, as shown in Figure 1, can find that prepared matrix material has the reflectivity up to 90% in wavelength 400-2500nm scope, can satisfy the requirement of reflection type thermal insulation coating fully.
