Abstract
The invention provides a composite air purifying agent and a preparation method thereof. The composite air purifying agent is prepared from the following raw materials in parts by mass: 5 to 12 parts of nanometer titania, 30 to 35 parts of activated carbon, 6 to 8 parts of stearic acid, and 50 to 70 parts of normal hexane. According to the composite air purifying agent, nanometer titania is located on the surface of activated carbon through stearic acid, so that the composite stability is high; when the activated carbon adsorbs the harmful pollution gas in the air, nanometer titania can decompose organic pollutants contained in the harmful pollution gas into carbon dioxide and oxygen, thus harmful substances attached on the activated carbon can be decreased, the activated carbon can continue adsorbing the harmful substances in the air, and as a result, the effective use time of the purifying agent is prolonged. The composite air purifying agent has indoor formaldehyde purifying rate up to 99.8%; stearic acid is adopted, so that the adsorption of nanometer titania to the activated carbon can be improved; nanometer titania is hard to leak; after the composite air purifying agent is continuously used for one week, the removal rate of formaldehyde in the air can also be up to 99%. The preparation method is simple and easy to carry out, and can be widely popularized and applied.
Description
Technical field
The invention belongs to the air purifying process field, be specifically related to a kind of composite air purifying agent and preparation method thereof.
Background technology
Current existing air purifying preparation is of a great variety, the cleanser that has the suction-operated that utilizes the porous masses such as active carbon to purify air, also have and plant extracts is combined reach the cleanser that taste removal purifies with chemical reagent, the former is environmentally friendly, can not cause secondary pollution, but clean-up effect is not good, the latter's clean-up effect is better, but meeting being caused to secondary pollution to environment, and less stable, can not preserve for a long time.Therefore its application is very limited, and can't meet people's user demand.
In sum, how to overcome the deficiencies in the prior art and become existing air purification field problem demanding prompt solution.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and propose a kind of composite air purifying agent and preparation method thereof, cleanser of the present invention can effectively absorb pernicious gas in air, can decompose being adsorbed in its surperficial organic pollution, and product stability is good, can be long time stored, the preparation method is simple.
Technical scheme of the present invention is as follows:
Composite air purifying agent comprises the following raw material according to the mass fraction meter: nano titanium oxide 5-12 part, active carbon 30-35 part, stearic acid 6-8 part, n-hexane 50-70 part.
The preparation method of composite air purifying agent: according to the quality proportioning, stearic acid is added in n-hexane, stir 2h under 55-60 ℃, add active carbon, after being warming up to 65 ℃ of backflow 4-5h, add nano titanium oxide, continue reaction 2h, after reaction finishes, filter and wash with n-hexane, in 40 ℃ of lower vacuum drying to constant weight, obtain finished product of the present invention.
Beneficial effect: first, the present invention is carried on activated carbon surface by stearic acid by nano titanium oxide, stable composition is good, when the airborne harmful dusty gas of charcoal absorption, nano titanium oxide can be decomposed into carbon dioxide and oxygen by organic pollution wherein, reduces and is adsorbed on the harmful substance on active carbon, makes active carbon can continue to absorb harmful substance in air, extended the effective storage life of cleanser of the present invention, the present invention can reach 99.8% to the purifying rate of indoor formaldehyde; The second, the stearic acid in the present invention has improved the absorption of nano titanium oxide to active carbon, and nano titanium oxide be difficult for to run off, and continues to use after one week, to the clearance of formaldehyde in air, still can reach 99%; The 3rd, preparation method of the present invention is simple, but wide popularization and application.
