Description
Technical field
The invention belongs to technology of fine chemicals, be specifically related to a kind of preparation method of the ultraviolet shielded coating of water-based based on ZnO quantum dot.
Background technology
The aspects such as easily degradable material (polymkeric substance, wood, the bamboo etc.) protection out of doors of transparent violet external shield coating, ultraviolet shielded glass preparation, the ultraviolet ray of indoor light source completely cut off have extensive use, generally by adding UV light absorber to prepare in varnish.UV light absorber generally can be divided into two large classes, and a class is organic uv absorbers, mainly comprises benzophenone class, benzotriazole category, salicylate class, oxanilide class etc.; Another kind of is the inorganic nano uv-absorbing agent, mainly contains titanium dioxide nano-particle, cerium oxide nanoparicles, zinc oxide nano-particle etc.The advantages such as the extinction coefficient of organic uv absorbers is large, shielding efficiency is high, shield wide waveband, the transparency is good, but there are light, poor heat stability, the shortcoming such as volatile, permanent stability are not good, and the organic uv absorbers degradation production has certain toxicity.Although the inorganic nano uv-absorbing agent has outstanding light, thermostability, easily reunite, realize ultraviolet shielded in, easily cause the transparency of coating to descend; Simultaneously, inorganic nano-particle has very strong photocatalytic activity, under ultraviolet effect, can accelerate the aging of polymeric coating and degraded, greatly reduces the work-ing life of coating.Chinese patent CN1412258A has reported by titanium dioxide or zinc oxide nano-powder grinding distribution, then has added preparation uvioresistant coating in polyacrylic resin.Because nano-powder can not reach the primary particle diameter dispersion level fully by grinding, cause the transparency of coating not good.Chinese patent CN101629033A has prepared the cerium oxide nanoparicles of doping calcium with the ultrasonic auxiliary law of carboxymethyl cellulose, and coat to reduce the photocatalytic activity of cerium oxide nanoparicles with the inertia shell, then silane coupling agent is modified, then with the ultraviolet shielded coating of the compound preparation of pure-acrylic emulsion.But in the method, cerium oxide nanoparicles has carried out sintering, and the dispersiveness in coating is not good, and the transparency of coating is low.As can be seen here, still urgently development of the preparation method of the ultraviolet shielded coating of environment-friendly type of high-weatherability, high transparent.
Zinc oxide quantum dot (ZnO QDs) ultraviolet absorption ability is strong, and fluorescent emission intensity is high, and has advantages of nontoxicly, is usually used in the biological fluorescent labelling material, is also the ideal chose of high transparent ultraviolet screener coating with the inorganic nano uv-absorbing agent.As, Li etc. are compound by ZnO QDs and fluoropolymer resin, prepared transparent violet external shield coating (S. Li, et al,
adv. Mater., 2007,19,4347).But, do not consider the photocatalytic activity of ZnO QDs in this research, and coating system is solvent-borne type.By amphipathic nature polyalcohol and tensio-active agent to the coating of ZnO QDs (N. R. Jana, et al,
chem. Commun., 2007,1406; H. M. Xiong, et al,
j. Am. Chem. Soc., 2008,130,7522; X. Tang, et al,
langmuir2009,25,5271.), can improve the water-soluble of ZnO QDs, but due to the photocatalytic activity of ZnO QDs, under the irradiation of UV-light, these amphipathic nature polyalcohols and tensio-active agent are easy to decompose, and cause ZnO QDs unstability, can't be for the preparation of high-weatherability, the ultraviolet shielded coating of high transparent water-based.
Summary of the invention
The object of the present invention is to provide a kind of method for preparing the ultraviolet shielded coating of water-based of high-weatherability, high transparent based on ZnO QDs.Specifically comprise the following steps:
Take respectively zinc salt and lithium hydroxide, ultrasonication fully is dissolved in dehydrated alcohol, then the ethanolic soln of the two is mixed to 60-78 ℃ of stirring reaction 3-10 h., obtain the dispersion liquid of ZnO QDs in ethanol.Add tetraethoxy and deionized water in ZnO QDs alcohol dispersion liquid, ultrasonicly fully mix, stirring at room is reacted 6 h, can obtain SiO
2clading ZnO QDs(ZnO QDs@SiO
2) dispersion liquid, by centrifugation, washing, by ZnO QDs@SiO
2transfer is dispersed in water, obtains ZnO QDs@SiO
2aqueous dispersions, then mix by a certain percentage with waterborne film-forming resin, wetting agent, after fully stirring, obtain the ultraviolet shielded coating of water-based.This coating can be coated on the substrate surfaces such as bamboo and wood, plastics, glass, and cryodrying is processed, and can obtain transparent violet external shield coating.
The ultraviolet shielded coating of water-based based on ZnO QDs of the present invention, the particle diameter that it is characterized in that ZnO QDs is 1-10 nm.Particle diameter is too little, is difficult for preparation, crystallinity deterioration, and the uv-absorbing ability weakens; Particle diameter is too large, and light scattering effect strengthens, and is unfavorable for preparing transparent violet external shield coating.
The ultraviolet shielded coating of water-based based on ZnO QDs of the present invention, the mol ratio that it is characterized in that zinc salt and lithium hydroxide is 1:4-2:3, temperature of reaction is 60-78 ℃.Wherein zinc salt is a kind of in zinc nitrate, zinc sulfate, zinc chloride and zinc acetate, has advantages of that cost is low, nontoxic.
The ultraviolet shielded coating of water-based based on ZnO QDs of the present invention, is characterized in that adopting SiO
2clading ZnO QDs, can effectively suppress the photocatalytic activity of ZnO QDs, can improve its dispersiveness in water, is conducive to its application in water-borne coatings simultaneously.SiO
2coating layer is by tetraethoxy in the preparation of ZnO QDs dispersion liquid situ sol-gel method, and wherein tetraethoxy adds by Si:Zn mol ratio 1-3 in 24 h after ZnO QDs preparation.The tetraethoxy add-on is very few, easily causes ZnO QDs to coat not exclusively, and photocatalytic activity can't effectively be completely cut off, and add-on is too much, easily causes ZnO QDs@SiO
2reunion between nanoparticle, even dispersion liquid system gel.Tetraethoxy add opportunity excessively late, ZnO QDs will become large because of Ostwald's ageing particle diameter, be unfavorable for the preparation of transparent violet external shield coating.
The ultraviolet shielded coating of water-based based on ZnO QDs of the present invention, is characterized in that adopted waterborne film-forming resin is one or more the mixture in benzene emulsion, pure-acrylic emulsion, organosilicon crylic acid latex, waterborne polyurethane resin, water-based organic-inorganic hybrid resin.

The ultraviolet shielded coating of water-based based on ZnO QDs of the present invention, is characterized in that the content range of ZnO QDs in dry coating is 1-50%, is preferably 2-30%, and the best is 5-20%.If ZnO QDs consumption is very few, ultraviolet shielded DeGrain; If consumption is excessive, the transparency of coating starts to reduce.
The coating of gained of the present invention can be coated on the substrate surfaces such as bamboo and wood, plastics, glass, and after drying, film has efficient uv-shielding capacity below wavelength 340 nm, simultaneously, at visible region, the high transparent close with the virgin resin coating is arranged.Because the photocatalytic activity of ZnO QDs is effectively completely cut off, no longer organic composition is produced to photocatalysis in filming, the weathering resistance of filming is good, the uv-shielding capacity long-term stability.
