Abstract
A nano-class photocatalyst composition for cleaning indoor air and killing bacteria contains proportionally TiO2 nanoparticles, anatase nanoparticles, zinc nitrate and epoxy resin APG. Its preparing process is also disclosed.
Description
Technical field
The invention belongs to chemical field, relate to a kind of Chemical composition that and preparation method thereof, further, the present invention relates to a kind of nanometer light catalyst composition and preparation method thereof.
Background technology
Photocatalyst is a kind of nano titanium oxide (TiO that contains
2) photochemical catalyst, utilize the irradiation of light source, produce the extremely strong hydroxyl free radical of oxidability, after pernicious gas on every side, pollutant, the bacterium contact, carry out oxidation-reduction reaction, effectively kill bacteria and eliminate various pernicious gases is converted into nuisance free of contamination water and carbon dioxide simultaneously, thus the effect that reaches environment purification, purifies air.Photocatalyst itself can not change or destroys body construction because of chemical reaction, and the use of the photocatalyst material that has and effect duration were 10 years.
Since TiO
2Be found and had since the light catalytic purifying function TiO
2Photocatalytic degradation, sterilization, antifouling, self-cleaning function be widely used.Identification was once done at U.S. FDA Food Inspection center, think that titanium dioxide does not have injury extremely to human body, thereby photocatalyst also can be widely adopted in food, daily living article, cosmetics, medicine, aquaculture when solving indoor pollution, can guarantee health to greatest extent.
According to the detection that national authority departments such as Chinese Indoor Environment Detection center and Chinese Center for Disease Control are done, the bactericidal effect of photocatalyst can reach 99%, and the elimination of pernicious gases such as PARA FORMALDEHYDE PRILLS(91,95), ammonia, benzene, VOC can reach more than 90%.
But, all there is a defective in photocatalyst in the market, do not having do not have photocatalytic degradation, sterilization, antifouling, self-cleaning function under the condition of illumination exactly, must competence exertion photocatalytic effect under the situation of illumination arranged, and the photocatalyst material adhesive ability that has is not strong, come off easily, do not reach required environmental protection purpose.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of nanometer light catalyst composition, its component is as follows according to percetage by weight: particle diameter is at the titania powder 10-20% of 0.3-1nm, nano-anatase 40-60%, zinc nitrate 5-15%, APG epoxy resin 10-25%.
As preferred embodiment of the present invention, nanometer light catalyst composition of the present invention is as follows according to percetage by weight: particle diameter is at the titania powder 15% of 0.3-1nm, nano-anatase 55%, zinc nitrate 10%, APG epoxy resin 20%.
Technical problem to be solved by this invention also is to provide the preparation method of described nanometer light catalyst composition, comprises following steps:
(1), prepares the various compositions of aequum, abundant mixing in deionized water with nano-anatase and titanium dioxide according to proportioning;
(2) mix with zinc nitrate fully dissolving in deionized water, and with (1) solution, be heated to 120-140 ℃, fully stir;
(3) with the solution cooling of (2), add APG epoxy resin;
(4) with the above-mentioned dope filtration removal of impurity, washing, drying is ground, and obtains finished product.
When using, nanometer light catalyst composition of the present invention can be joined in various paint, coating, plastics, the fibre, make the various goods that contain photocatalyst; And directly be coated on the top layer of timber, wall.
Nanometer light catalyst composition of the present invention has added zinc nitrate on the basis of adopting general catalyst material, can produce zinc ion, according under the condition, also can bring into play degraded, sterilization, antifouling, self-cleaning function unglazed.
Nanometer light catalyst composition of the present invention has very strong oxidizing force, can be with airborne organic substance, H
2Harmful substances such as the formaldehyde in S and the room air, benzene, ammonia are decomposed into CO
2And water, and there is not the intermediate product generation, the effect safety that purifies air, sterilizes, brute force, lasting.
The specific embodiment
According to the aforementioned optimum ratio that provides: particle diameter is at the titania powder 15% of 0.3-1nm, nano-anatase 55%, and zinc nitrate 10% and APG epoxy resin 20% are prepared nanometer light catalyst composition of the present invention.
At first, the abundant mixing in deionized water with nano-anatase and titanium dioxide, this step can be carried out at normal temperatures.
Then, zinc nitrate is fully dissolved in deionized water, and mix, be heated to 130 ℃, fully mix with the solution of aforementioned preparation.To mix in order making, can in special agitator, to carry out.
Then, the solution cooling with aforementioned preparation adds APG epoxy resin.
With the above-mentioned dope filtration removal of impurity, washing, drying is ground, and obtains finished product.
After testing, the bactericidal effect of nanometer light catalyst composition of the present invention can reach 99.9%, and the elimination of pernicious gases such as PARA FORMALDEHYDE PRILLS(91,95), ammonia, benzene, VOC can reach more than 95%.
