Abstract

The invention discloses a use method of nanometer titanium dioxide on ceramics, leather, cloth and furniture, and relates to the technical field of materials. The use method comprises: S1, adding a Ti<4+> salt solution into hydrogen peroxide, and carrying out a flocculation reaction on the Ti <4+> salt solution and the hydrogen peroxide to prepare a titanium peroxide complex; S2, adding a crystalform control agent into the titanium peroxide complex, carrying out a reaction on the crystal form control agent and the titanium peroxide complex, heating to 300-500 DEG C, and keeping for 5-10 hto obtain a titanium oxide blocky gel; and S6, adding a silane coupling agent into the nanometer titanium dioxide sol, and adding the mixed solution into a water-based glass baking varnish resin accordingto the adding amount of 0.5-1.5% of the nanometer titanium dioxide. According to the invention, the resin coating material is mixed and processed into glass, furniture and ceramic finished products,so that the glass, furniture and ceramic finished products have photocatalysis function, can catalyze and photolyze various organic matters such as formaldehyde and the like and part of inorganic matters attached to the surface of objects, have a self-cleaning function, improve automatic cleaning effect and are convenient to clean.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a method for using nano-titanium dioxide on ceramics, leather, fabrics and furniture. Background technique [0002] Nanoscale titanium dioxide, also known as titanium dioxide. The diameter of the product is less than 100 nanometers, and the appearance of the product is white loose powder. It has anti-wire, antibacterial, self-cleaning and anti-aging properties, and can be used in cosmetics, functional fibers, plastics, inks, coatings, paints, fine ceramics and other fields. [0003] Nano-titanium dioxide mainly has two crystalline forms: anatase and rutile. Rutile titanium dioxide is more stable and denser than anatase titanium dioxide, has higher hardness, density, dielectric constant and refractive index, and its hiding power and tinting power are also higher. The reflectivity of anatase titanium dioxide in the short-wave part of visible light is higher than that of rutile...
