Inorganic nonmetallic mineral composite material carrying titanium dioxide layer, production method and application

摘要

The present invention discloses a composite material comprising an inorganic non-metallic mineral as a carrier and a nano titanium dioxide layer supported on the carrier, wherein the layer comprises a plurality of titanium dioxide nanospheres, These nanospheres are composed of a plurality of titanium dioxide nano-single particles. The present invention also discloses a composite material in which one or more functional layers are supported on the nano-titanium dioxide layer. In the above composite material, the nano titanium dioxide layer not only exhibits the advantages of high refractive index and high blocking power, but also exhibits the excellent photocatalytic activity of its small nano-single particles, and more easily coats other functional layers In this way, a composite material having a function-enhancement type or multiple functions can be produced. Furthermore, although the present invention has disclosed a method for producing a composite material, the process is simple and the cost is low. The composite material of the present invention can be used as an additive in various industrial fields and has excellent compatibility.
