Problems solved by technology

[0005] However, there is a defect in the photocatalysts currently on the market, that is, they do not have photocatalytic degradation, sterilization, antifouling, and self-cleaning functions under the condition of no light, and the photocatalytic effect must be exerted under the condition of light. The photocatalyst material has weak adhesion and is easy to fall off, failing to achieve the required environmental protection purpose

Embodiment Construction

[0016] The nanophotocatalyst composition of the present invention is prepared according to the preferred proportion provided above: 15% of 0.3-1nm titanium dioxide, 55% of nano de-titanium ore, 10% of zinc nitrate and 20% of APG epoxy resin.

[0017] Firstly, fully mix the nanode-titanium ore and titanium dioxide in deionized water, and this step can be carried out at normal temperature.

[0018] Then, zinc nitrate was fully dissolved in deionized water, and mixed with the previously prepared solution, heated to 130°C, and fully stirred and mixed. In order to make the mixing even, it can be carried out in a special mixer.

[0019] Next, cool the previously prepared solution and add APG epoxy resin.

[0020] The above slurry is filtered to remove impurities, washed, dried and ground to obtain the finished product.

[0021] After testing, the bactericidal effect of the nano photocatalyst composition of the present invention can reach 99.9%, and the elimination of formaldehyde,...

Abstract

A nano-class photocatalyst composition for killing the bacteria in air and decomposing the harmful substances (organic substance, H2S, formaldehyde, benzene, ammonia, etc) in indoor air into CO2 and H2O contains nano-TiO2 (10-20 Wt%), nano-class detitanating mineral (40-60), zinc nitrate (5-15) and epoxy resin APG (10-25).

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a chemical composition. Furthermore, the invention relates to a novel nano photocatalyst composition. Background technique [0002] Photocatalyst is a nano-titanium dioxide (TiO 2 ) photocatalyst, using the light source to produce hydrogen and oxygen free radicals with strong oxidizing ability, and after contacting the surrounding harmful gases, pollutants and bacteria, an oxidation-reduction reaction will be carried out to effectively kill bacteria and eliminate various harmful gases , At the same time, harmful substances are converted into non-polluting water and carbon dioxide, so as to achieve the effect of purifying the environment and purifying the air. The photocatalyst itself will not change or destroy the structure of the body due to chemical reactions, and the use and effect of some photocatalyst materials can last as long as ten years. [0003] Since TiO 2 Since it was...
