Background technology
Titanium dioxide stable performance, toxicological harmless effect, have high refractive index (n=2.4), thereby be widely used in industries such as coating, printing ink, papermaking, plastics, rubber, regenerated fiber, welding electrode, enamel, electrical equipment, building materials.Since Fujishima in 1972 and Hondav find the optically catalytic TiO 2 characteristic, be that the photocatalytic environmental-protection material of representative obtains extensive studies with titanium dioxide.Nano titanium dioxide photocatalyst demonstrates wide application prospect so that its photolytic activity is good, photocatalysis efficiency is high, nontoxic, oxidation capacity strong in photocatalysis field.This photocatalyst can make harmful chemical soluble in water innoxious; Be used in the room air pollution control, can eliminate pollutions such as formaldehyde, ammonia, reduce volatile organic compounds concentration.The anatase titanium dioxide energy gap is 3.2eV, thus its light absorption wavelength fault value in the ultraviolet region (λ≤387nm), thereby can utilize the ratio of solar energy low (only accounting for the 3%-5% of incident sunlight total energy).Therefore, titanium dioxide being carried out modification, thereby reduce the semi-conductor energy gap, realize the effective utilization to visible light, is the important channel of improving optically catalytic TiO 2 efficient, enlarging its practical ranges.Modification way commonly used is some element (as iron) that mixes in titanium dioxide nanocrystalline.In addition, nano-photocatalyst is easily reunited, thereby reduces photocatalytic activity, and the dispersiveness that therefore improves nano-photocatalyst is also significant in actual applications.
Hollow glass micropearl has light weight, density is little, heat-insulating property is good characteristics, is the weighting agent of heat preserving and insulating material.Combine with hollow glass micropearl modifying titanium dioxide is nanocrystalline, form advanced composite material, to improve the dispersiveness of titanium dioxide nanocrystalline photocatalyst in liquid phase greatly on the one hand, this composite granule not only might comprehensive hollow glass micropearl and the advantage of iron doped nano titanium dioxide on the other hand, also be expected to utilize synergistic effect to introduce new physicochemical characteristic simultaneously, expand the Application Areas of nano material.
Summary of the invention
The present invention proposes a kind of preparation technology of multifunctional composite powder body, and this composite granule is by hollow glass micropearl and be carried on the iron doped nano titanium dioxide that its surperficial one deck has meso-hole structure and form.Purpose is the advantage in conjunction with hollow glass micropearl and modified nano-titanium dioxide, obtains the good advanced composite material of function, and develops its application in photo-catalyst and heat insulating coatings field.
The present invention adopts the cohydrolysis precipitator method under the metal-salt hot water system to prepare multifunctional composite powder body, and concrete steps comprise:
1. take by weighing an amount of hollow glass micropearl, water and, place beaker to stir and make it to mix and heat as the sodium lauryl sulphate of stablizer.
2. take by weighing an amount of titanium salt and molysite, be dissolved in distilled water and be made into the aqueous solution, cofabrication certain density aqueous sodium hydroxide solution is used for the hydrogen ion that produces in the neutralizing hydrolysis reaction process.Then the aqueous solution of titanium salt and molysite is dropwise splashed in the mixed solution in the above-mentioned steps 1, simultaneously with the proper speed dropping sodium aqueous solution.
3. after reaction was finished, the mixed solution that obtains was through separation, washing, drying, and final product places crucible, in 300-700 ℃ of roasting, obtains faint yellow powder in retort furnace.
X-ray diffraction and sem test show, this powder is made up of the spherical particle of size 10-50 μ m, grain pattern is that the nanocrystalline intensive hollow glass micropearl surface that is covered in of the adulterated anatase titanium dioxide of iron forms a skim, titanium dioxide nanocrystalline is of a size of 5-50nm, and thicknesses of layers is 50-500nm.
With 300 watts halogen light modulations (adding spectral filter filters the light of wavelength＜420nm) is visible light source, carries out the visible light photocatalysis experiment.Get 100mg composite granule (titanium dioxide nanocrystalline weight accounts for 20%), be scattered in 50mL, 10
-5In the methyl orange aqueous solution of M.Under radiation of visible light, certain hour sampling is at interval surveyed the strongest absorption peak strength changing conditions of tropeolin-D with the ultraviolet-visible absorption spectrum, characterizes the degradation rate of tropeolin-D at the reaction different time with this.The result shows that the methyl orange degradation rate prolongs with the visible light irradiation time and increases; Through 7 hours irradiation, the methyl orange degradation rate was near 40%.The composite granule additive can be suspended in the aqueous systems, and is easy to separate with aqueous systems, helps reclaiming.
Characterize reflective character with the UV, visible light diffuse reflectance spectra, the result shows that composite granule of the present invention has very high reflectivity to the radiation of near-infrared band.Composite granule is mixed by a certain percentage with commercially available common exterior coating, only need, just can realize evenly, stable dispersion through stirring at low speed; Its luminous reflectance factor of exterior coating (especially at infrared band) that has added composite granule increases significantly.According to simultaneous test, the interpolation weight ratio of composite granule additive in coating is 15% o'clock, the luminous reflectance best results of coating, and the average light reflectivity of 500nm-1500nm wave band (this wave band covers between the main energy range of sunlight) is higher than 85%.
Hollow glass micropearl load of the present invention, has the iron doped nano titanium dioxide composite granule of meso-hole structure, the preparation method is easy, raw material is cheap, good visible light photocatalysis active and near infrared light reflection characteristic are arranged, have the function of antifouling, deodorization, antibiotic (sterilization), can be used for the degraded of organic pollutant; Add an amount of composite granule in the exterior coating, the infrared reflectivity height in the incident sunlight can play the heat-insulation and heat-preservation effect.
