Embodiment Construction

[0018] The present invention is further illustrated by the following examples.

[0019] In a preferred embodiment of the present invention, said this photocatalyst indoor wall surface spraying agent is made of concentration more than 99.9% alcohol, dibutyltin dilaurate, modified alcohol-soluble organic silicon, nano-titanium dioxide and Silane coupling agent, of which alcohol accounts for 35%-37%, cured resin accounts for 1-2%, modified silicone accounts for 50-60%, nano-titanium dioxide accounts for 1-3%, and silane coupling agent accounts for 0.5-1%. .

[0020] The method for making photocatalyst indoor wall surface spraying agent of the present invention comprises the following steps:

[0021] (1) titanium dioxide powder is dried, carries out alcoholization treatment and ultrafine filtration;

[0022] (2) The ultrafine filtration product and alcohol-soluble organic silicon are stirred and synthesized in a reactor;

[0023] (3) adding auxiliary agent silane coupling agent...

Abstract

A photocatalytic paint of indoor wall for cleaning air, decomposing formaldehyde, benzene and organic compound, and killing bacteria and viruses is prepared from alcohol, solidifying resin, modified organosilicon, anatase-type TiO2 and assistant. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to building decoration materials, in particular to a photocatalyst indoor wall surface spraying agent. Background technique [0002] In the prior art, in order to improve the indoor air environment, a large number of novel green and environment-friendly coatings continue to emerge. Photocatalyst interior coatings are used, and the main component of photocatalyst is titanium dioxide (Titanium oxide, Tio 2 ), under the irradiation of sunlight or ultraviolet rays in the lighting source, it can generate charges, react with water molecules and oxygen molecules in the air, and produce negative oxygen ions and hydroxyl radicals. These substances have super strong oxidation ability and can destroy The cell wall of bacteria can cause the cytoplasm of bacteria to lose and die. It can also coagulate the protein of viruses, inhibit the growth of viruses, and capture various planktonic bacteria in the air. However, what currently uses photoc...
