Principle of work of the present invention is as follows: the sun at every moment huge energy to terrestrial radiation, the solar radiation spectrum in the earth atmosphere upper bound more than 99% between 0.15～4.0 micron of wavelength, about 50% solar radiation energy is (0.4～0.76 micron of wavelength) in the visible range, 7% in the UV spectrum district (wavelength＜0.4 micron), 43% at infrared spectral region (wavelength〉0.76 micron), and beta maximum energy is at 0.475 micron place of wavelength; Solar radiation is by atmosphere, and a part arrives ground, is called direct solar radiation; Another part is absorption, scattering and the reflections such as the molecule, the micronic dust in the atmosphere, steam of atmosphere; A solar radiation part that is scattered is returned the outer space, and another part arrives ground, and this part of arrival ground is called diffusesolarradiation; The diffusesolarradiation and the direct solar radiation sum that arrive ground are called total radiation; Solar radiation is by behind the atmosphere, its intensity and spectral power distribution all change, and the solar radiation energy that arrives ground is more much smaller than aeropause, and energy distribution almost disappeares in the UV spectrum district on solar spectrum, be reduced to 40% in the visible range, and increase to 60% at infrared spectral region.Solar light irradiation all can produce reflection, absorption and transmission phenomenon on any object; Wherein, there is following relation: ρ+α+r=1 between its reflectivity ρ, specific absorption α and the transmissivity r.Because the following matrix of filming mostly is the materials such as opaque mortar, concrete, putty, thus can be similar to think transmittance r=0, following formula is reduced to ρ+α=1.Hence one can see that, improve the heat-proof quality of filming, and will reduce the specific absorption of filming, and will reduce the specific absorption of filming, and can adopt two kinds of measures: direct method and indirect method.Direct method adopts exactly gives the hydrophobicity of filming, and reduces the invade profit of rainwater to filming, and stops moisture to the internal penetration of filming, and reduces the water ratio of filming, and the thermal conductivity that reduces to film reduces specific absorption.Indirect method is exactly according to ρ+α=1, the specific absorption α that the reflectivity ρ that increase is filmed comes relative reduce to film.
The present invention utilizes direct method, in prescription, add hydrophobizing agent, hydrophobizing agent adds the surface that can form rapidly a kind of special construction in the coating at coating surface, similar with the chessboard of chess, the black square of imagination chessboard is hydrophobic surface, white square is water-wetted surface, be that hydrophobic surface and water-wetted surface are staggered, by adding the nano material of different-grain diameter and structure, the quantity of control hydrophobic surface and the power of hydrophobicity, last its macro surface shows as both hydrophobic, and certain wetting ability is arranged again, does not affect ventilation property and the recoatability of filming simultaneously.This shows, the adding of hydrophobizing agent, not only making films has certain hydrophobic waterproof self-cleaning function, and make the surface tension decrease of filming, and increased the contact angle of water, reduced the invade profit of rainwater to filming, stop moisture to the internal penetration of filming, reduced the water ratio of filming, the thermal conductivity that reduces to film has finally reduced the specific absorption of filming to solar spectrum.
The present invention has utilized indirect method simultaneously, adds nano heat-insulating powder slurry in prescription, and the good reflective heat-insulation paint of heat-proof quality is filmed and mainly is made of transmitance height macromolecule resin, the functional filler that plays reflected solar radiation and other necessary component.Wherein, selecting of functional filler is the key factor that affects heat-proof quality.The present invention has chosen the nano modification heat-insulating powder, and the main component of nano heat-insulating powder slurry is rutile type nano titanic oxide and metal oxide ir radiation powder.The refractive index of rutile titanium dioxide is 2.8, and reflection coefficient is 80%, and solar radiation is had good reflected refraction effect.It is titanium dioxide about 250 ~ 400 nanometers that nano heat-insulating powder slurry adopts particle diameter, and this size is about about half of the visible spectrum of concentration of energy and infrared spectra wavelength, and it is had best reflecting effect.And, use active organic group that processing is wrapped up on the surface of titanium dioxide, not only improve the reflectivity of titanium dioxide surface, and make it in the non-microbead type architectural reflective heat-insulation paint of hydrophobicity, reduce gathering, disperse more even, the raising reflection efficiency.
In addition, natural object when absorbing sunlight also constantly to extraneous irradiating infrared light and the longer hertzian wave of wavelength.This radiation is that the thermal motion by molecule, atom causes, the surface properties of the size of quantity of radiant energy and temperature and object has very close relationship, is commonly referred to as thermal radiation.The periphery of the earth is wrapped in thick atmospheric layer, the gas and the various suspended substances such as water vapour, dust that contain nitrogen, oxygen, carbonic acid gas, ozone in the atmospheric layer, reflection, sorption are played in the thermal radiation that these materials send ground object, hamper the object thermal radiation to the energy dispersal in outer space.But in 8 ~ 13.5 microns wavelength band, the materials such as water vapour, carbonic acid gas and ozone are very weak to thermal-radiating absorption and reflection potential, and the transparency of atmosphere in this wave band is high, is commonly referred to atmospheric window.The thermal radiation of ground object can be hanged down continually and directly be passed atmospheric window and reach the outer space, realizes diffusion and the release of energy.
Although distribute outside the external world through the reflection of film coated surface and the Multi reflection on the middle titanium dioxide heat-insulating powder surface of filming, still have the sunlight of small part to enter the inside of filming and be converted into heat.Metal oxide ir radiation powder in the nano heat-insulating powder slurry has higher emittance at 8 ~ 13.5 microns, and the heat in filming is transmitted into the external world in infrared mode by atmospheric window, further reduces and films to sun Optical Absorption.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the present invention's design has obtained a kind of new reflective heat-insulation paint for building, adopt the nano modification heat-insulating powder, the main component of nano heat-insulating powder slurry is rutile type nano titanic oxide and metal oxide ir radiation powder, it has very high reflection, obstruct and radiance, good heat-insulation effect to solar spectrum.
2. the present invention has added suitable hydrophobizing agent in formulation for coating material, so that film coated surface has larger contact angle to water, reducing rainwater invades profit and permeates what film, the water ratio that reduces to film, not only give certain hydrophobic water-repellancy of filming, and reduced the thermal conductivity of filming, and finally reduced the specific absorption of filming to solar spectrum, improve the thermal insulation of filming.
The concise production process of coating of the present invention, low cost, construction is easy, the duration is short, aqueous, environmental protective, nontoxicly do not fire, and production technique is simply efficient, facility investment is little, can be widely used in the various smooth and special-shaped part of external surface of buildings.
