Abstract

The embodiment of the invention discloses a photocatalyst coating and a preparation method thereof. The photocatalyst coating comprises the raw materials: slurry and a base material; according to theweight parts, the slurry is mainly prepared from the following components: 40 parts of anatase nano titanium dioxide, 40 parts of rutile nano titanium dioxide, 140-150 parts of titanium dioxide, 300-325 parts of an extender pigment, 12.5-23 parts of a slurry additive and 200-230 parts of water; the base material is mainly prepared from the following components in parts by weight: 300-310 parts ofacrylic synthetic resin and 49-76 parts of a base material additive. The coating can release negative ions for a long time, is high in negative ion number, green and pollution-free, does not cause harm to human health, has an excellent air purification function, can purify harmful gases such as formaldehyde, ammonia and benzene in air, and is high in antibacterial property, alkali resistance, scrub resistance, stability, film forming speed and constructability.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of coatings, in particular to a photocatalyst coating and a preparation method thereof. Background technique [0002] Paint is one of the indispensable materials in the process of home decoration. In recent years, with the continuous improvement of people's lives, people have higher and higher requirements for paints, and their varieties have also developed from tung oil and Kaisheng paints to synthetic resin paints to meet the needs of different consumers. [0003] However, studies have proved that traditional coatings will slowly release small molecular harmful substances such as aldehydes and phenols, which will easily cause serious damage to human health. In addition, with the increasing industrialization and urbanization of human society, urban air pollution is becoming more and more serious. Moreover, various harmful microorganisms in the room are the main causes of various p...
