Problems solved by technology

[0004] Titanium dioxide has three crystal forms, namely brookite, anatase and rutile. The common rutile is generally extracted from rutile by acid decomposition. The preparation process of conventional rutile titanium dioxide is very cumbersome, and a large amount of rutile remains after preparation. Chemical pollutants, not only the preparation cost is high, but also not conducive to the protection of the environment

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] There are three crystal forms of titanium dioxide, which are brookite, anatase and rutile. Brookite has the worst photocatalytic performance and stability, and there is basically no related research and application. The anatase type and rutile type both belong to the tetragonal crystal system, and both crystal types are composed of interconnected TiO 6 Each Ti atom is located in the center of the octahedron and is surrounded by 6 O atoms. The differenc...

Abstract

The invention discloses a preparation method of titanium dioxide for antibacterial air purification waterborne paint. The invention is mainly directed at purification of rutile titanium dioxide and attachment of metal ions. The preparation method includes the steps of: taking industrial titanium dioxide with a weight ratio of 1 and putting the industrial titanium dioxide in a muffle furnace, conducting high temperature calcining in air atmosphere for 3h, and performing cooling and collecting; conducting crushing by a crusher, then adding deionized water with a weight ratio of 2, mixing the substances fully and evenly for dilution, then performing grinding by a nano-grinder to obtain a high purity nano-titanium dioxide solution; taking copper chloride pentahydrate with a weight ratio of 0.03-0.04, adding deionized water with a weight ratio of 1 for dilution to form a copper ion solution; and adding the prepared nano-titanium dioxide solution and performing mixing, then putting the mixture in water bath for dispersion at a low rotational speed to attach metal ions to the surface of nano-titanium dioxide, thus obtaining titanium dioxide for antibacterial air purification waterborne paint.

Description

technical field [0001] The invention relates to the field of water-based coatings, in particular to a preparation method of titanium dioxide for antibacterial air-purifying water-based coatings. Background technique [0002] The appearance of nano-titanium dioxide coating is white liquid, and its main functional component is nano-titanium dioxide. Nano-titanium dioxide has a strong redox ability under the action of visible light or ultraviolet light, and its chemical properties are stable. It can remove harmful organic substances, pollutants, odors, bacteria, microorganisms, etc. Harmful organic substances are completely decomposed into harmless CO2 and H2O, and have the characteristics of removing pollutants, hydrophilicity, self-cleaning, antibacterial, etc., with long-lasting performance and no secondary pollution. [0003] In recent years, doping titanium dioxide with metal ions to improve the catalytic performance of titanium dioxide has become a relatively popular res...
