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
The present invention relates to building and ornament materials, particularly a kind of photocatalyst indoor wall spraying agent.
Background technology
In the prior art, for improving indoor air environment, a large amount of novel environmental type coating constantly occur.The photocatalyst indoor paint finds application, main component titanium dioxide (Titaniumoxide, the Tio of photocatalyst
2), can produce electric charge under the uviolizing in sunlight or lighting source, react with airborne water molecules and oxygen molecule, produce negative oxygen ion and hydroxyl free radical, these materials have superpower oxidation capacity, can destroy the cell walls of bacterium, the tenuigenin of bacterium is run off and death, can also solidify the protein of virus, suppress the growth of virus, and catch airborne various bacterioplankton.But what use photo-catalytic coating at present is water soluble paint, and there is the problem of length time of drying, poor adherence, oxygen-proof property difference in water soluble paint.
Summary of the invention
Technical problem of the prior art to be solved by this invention is: because the photo-catalytic coating that generally uses in the prior art is water soluble paint, thus exist time of drying long, the problem of poor adherence, oxygen-proof property difference.The technical scheme that the present invention is adopted for solution above-mentioned technical problem of the prior art provides a kind of photocatalyst indoor wall spraying agent, described this photocatalyst indoor wall spraying agent is made up of alcohol, cured resin, modified organic silicon, nano titanium oxide and silane coupling agent, wherein alcohol accounts for 35%～37%, cured resin accounts for 1～2%, modified organic silicon accounts for 50～60%, nano titanium oxide accounts for 1～3%, and silane coupling agent accounts for 0.5～1%.
Concrete, described alcohol be that concentration is at the alcohol more than 99.9%.
Concrete again, described cured resin is a dibutyl tin dilaurate.
Further, described modified organic silicon is the organosilicon through pure dissolubility after the modification.
Further, modified organic silicon of the present invention is through after the modification being pure dissolubility, with tetraethoxy in autoclave with highly purified alcohol (1Mpa pressure, 50 ℃ of temperature) synthetic, on 0.01 μ m ultra-filtration membrane, carry out ultrafiltration, add silane coupling agent and defoamer again, form pure dissolubility organosilicon.
The organosilyl PH of pure dissolubility that the present invention forms be a neutrality, and PH is about 7.1, Si content 35%～37%.Modified organic silicon is stable, oxidation resistant tackiness agent.In use, alcohol volatilizees fast, and the organosilicon ratio constantly increases, very fast film forming.
Also comprise the method for making photocatalyst indoor wall spraying agent of the present invention in the technical scheme that the present invention is adopted for solution above-mentioned technical problem of the prior art, comprised following steps in the described method:
(1) titanium dioxide powder drying is refined and is handled and ultrafiltration;
(2) ultrafiltration product and pure dissolubility organosilicon stir in reactor, synthesize;
(3) adding the auxiliary agent silane coupling agent synthesizes;
(4) carry out ultrasonication;
(5) add cured resin and synthesize, form finished product, concrete, described cured resin is a dibutyl tin dilaurate.
Effect of the present invention is actively with tangible.Photocatalyst indoor wall spraying agent of the present invention is under the irradiation of sunlight or fluorescent lamp, very strong oxygenolysis is arranged, used pure dissolubility organosilicon, binding agent self has not been decomposed by photocatalyst destroy, spraying agent can form transparent robust cured film on metope.
Photocatalytic spray agent of the present invention, its bounding force can reach 5 grades, has guaranteed that the katalysis of photocatalyst agent is permanently effective; Fungicidal properties reaches 0 grade, is better than general coating; Antibacterial effect reaches 90%～99%; But also having strengthened humidity resistance, the metope stain is cleaned easily.
Photocatalytic spray agent of the present invention purifies air, sterilization is killed the virus, and ability is permanently effective, reaches more than 60% for formaldehyde, benzene, the secular capacity of decomposition of organic chemistry synthetics, and need not consume luminous energy other energy in addition.
Embodiment
Further specify the present invention by the following examples.
In a preferred embodiment of the invention, described this photocatalyst indoor wall spraying agent is made up of organosilicon, nano titanium oxide and the silane coupling agent of concentration pure dissolubility after the alcohol more than 99.9%, dibutyl tin dilaurate, modification, wherein alcohol accounts for 35%～37%, cured resin accounts for 1～2%, modified organic silicon accounts for 50～60%, nano titanium oxide accounts for 1～3%, and silane coupling agent accounts for 0.5～1%.
Make and comprise following steps in the method for photocatalyst indoor wall spraying agent of the present invention:
(1) titanium dioxide powder drying is refined and is handled and ultrafiltration;
(2) ultrafiltration product and pure dissolubility organosilicon stir in reactor, synthesize;
(3) adding the auxiliary agent silane coupling agent synthesizes;
(4) carry out ultrasonication;
(5) add the dibutyl tin dilaurate cured resin and synthesize, form finished product,
Concrete, ultrafiltration product described in the step (2) and pure dissolubility organosilicon stir in reactor, comprise in the building-up process: tetraethoxy in autoclave with highly purified alcohol (1Mpa pressure, 50 ℃ of temperature) synthesize, on 0.01 μ m ultra-filtration membrane, carry out ultrafiltration then, the process that adds silane coupling agent and defoamer again obtains, measuring the organosilyl PH of pure dissolubility is 7.1, Si content 37%.
After measured, the bounding force of the spraying agent of acquisition is to 5 grades, and mildew resistance is 0 grade, and antibacterial effect reaches 96%.
