Abstract

The invention relates to a titaniferous composition, a method for forming a nano particle film on a ceramic or glass surface from the titaniferous composition and application of the titaniferous composition. The method comprises the following steps of: firstly adding 108 parts of distilled water into a reaction kettle, then adding 0.01-30 parts of template agent, adding a mixed liquid comprising a metal oxide precursor prepared by mixing 0.01-10 parts of metal inorganic salt or organic alkoxide with 0.1-40 parts of one or more than two fatty alcohols and 0.01-20 parts of nano metal, and uniformly stirring the mixture to obtain the titaniferous composition. The titaniferous composition can form a titanium dioxide nano particle film on the ceramic or glass surface through spray coating, brush coating and the like. The nano particle film has excellent antibacterial self-cleaning property and also has the function of resisting pollution flashover when being applied to high voltage ceramic or glass insulators. The titaniferous composition can be used for protecting the health of human and improving life quality in daily life, the pollution flashover problem of high voltage insulators can be effectively solved, and the titaniferous composition has wide economic benefit and social benefit.

Description

【Technical field】 [0001] The invention relates to the technical field of nanometer materials. More specifically, the present invention relates to a titanium-containing composition, and relates to a method for forming a nanoparticle film on the surface of a ceramic or glass substrate material by the titanium-containing composition.
