Description
Technical field
The invention belongs to field of inorganic nonmetallic material, relate to the nano-ZnO/TiO of prepared by co-precipitation shielding ultraviolet rays
2A kind of novel preparation technology of composite granule.
Background technology
Since the eighties in last century, the ecotope that the mankind depend on for existence has caused the concern of countries in the world.People such as the Scotto of the U.S. set up many ground survey ultraviolet ray point of observation in the U.S., and measuring result shows: the ground amount of ultraviolet irradiation increases obviously in the period of 12, and ecotope and human health have been caused tremendous influence.Along with the enhancing of people's health perception, ultraviolet screener has caused the extensive concern of domestic and international material educational circles.Traditional ultraviolet screening agent great majority are organism, as benzophenone series, benzotriazole system, salicylate system etc.The wavelength of their shielding ultraviolet rays is shorter, decomposes easily, and the certain toxicity of existence in various degree, its ultraviolet screener performance can reduce gradually along with the prolongation of coating Exposure to Sunlight time, ultimate failure.Because the development of nanometer material science technology is used some nano inoganic particle that the ultraviolet screener performance is arranged as the uvioresistant additive, has become one of focus of research.In recent years such as the ultraviolet light screener of a collection of inorganic powders such as zinc oxide, titanium dioxide and red iron oxide of nanometer scale, because very high chemical stability, thermostability, non-migrating, tasteless, nontoxic, nonirritant are arranged, use saferly, thereby gain great popularity.Most widely used is nano-TiO
2, ZnO.Nano-ZnO, TiO
2It is strong to absorb ultraviolet ability, and UVA, UVB are had shielding effect, and visible light transmissivity is big.So inorganic nano anti ultraviolet agent nano-TiO
2, ZnO climbs up the stage of world's ultraviolet ray-resistant material very soon, be widely used in all kinds of daily chemical products, and progressively replaced some organic uv absorbers.The direction of research mainly is the preparation of the single powder of shielding ultraviolet rays at present.
Though nano-TiO
2With ZnO good shielding ultraviolet rays performance is arranged all, but at ultraviolet long-wave band nano-TiO
2Not as nano-ZnO; And at the ultraviolet medium wave band, nano-TiO
2The shielding ultraviolet rays ability be much higher than nano-ZnO.Combining nano TiO
2Can make the excellent more wide spectrum ultraviolet light screener of uv-shielding capacity with the advantage of ZnO.Nano level ZnO/TiO
2Composite granule research is used has development prospect.
Look into by retrieval newly, domestic still do not have to report with the metatitanic acid to be raw material, prepares the nano-ZnO/TiO of shielding ultraviolet rays with coprecipitation method
