Problems solved by technology

[0003] In the prior art, the plant absorption method is often used, for example, plants such as tiger Piran, Chlorophytum, tropical fruits such as pineapples, tea leaves or pomelo peels are used to remove odors. It has the characteristics of absorption and aroma masking, and is cheap and effective, but the removal speed It is relatively slow, and the emerging photocatalytic methods mostly use photocatalyst materials to achieve the effect of removing odors under the excitation of light. Generally, they have a certain removal and killing effect on some organic matter and bacteria, but the effect is not good and the practicability is limited.

[0028] Preparation of bismuth vanadate

[0029] Dissolve 0.0015 mol of sodium vanadate and 0.006 mol of bismuth nitrate in deionized water respectively, drop the sodium vanadate solution into the bismuth nitrate solution drop by drop, stir for 30 minutes, let it stand for 5 hours, and put it in a constant temperature drying box After reacting at 160 degrees Celsius for 12 hours, after cooling to room temperature, continue to keep stirring and add 0.01 mol of hydrogen peroxide, filter with suction, wash and dry to obtain bismuth vanadate powder.

[0030] At room temperature, 8 parts by weight of tantalum pentachloride were dissolved in 100 parts by weight of absolute ethanol to obtain a tantalum pentachloride ethanol solution, which was left to stand for 15 minutes; 15 parts by weight of bismuth vanadate, 0.08 parts by weight of sulfurous acid Add sodium hydrogen to seal the HDI into the tantalum pentachloride ethanol solution, and combine evenly to obtain the first mixed solut...

Embodiment 1

[0032] In the container of the stirring device, 100 parts by weight of water-based polyurethane A2, 15 parts by weight of nano-zinc oxide and zirconia balls are added to the container, stirred at 3000 rpm for 2 hours, then filtered to remove the zirconia balls, and 0.12 parts by weight of Hydrogen peroxide, stirring at 1000 rpm for 2 hours; adding 6 parts by weight of the modified nano-tantalum oxide prepared above, stirring at 1000 rpm for 1 hour, adding 3 parts by weight of polyacrylamide and stirring evenly to obtain a polymer Deodorant.

Embodiment 2

[0034] In the container of the stirring device, 100 parts by weight of water-based polyurethane A2, 24 parts by weight of nano-zinc oxide and zirconia balls are added to the container, stirred at 3000 speeds for 2 hours, then filtered to remove the zirconia balls, and 0.27 parts by weight of Hydrogen peroxide, stirring at 1000 rpm for 2 hours; adding 9 parts by weight of the modified nano-tantalum oxide prepared above, stirring at 1000 rpm for 1 hour, adding 3 parts by weight of polyacrylamide and stirring evenly to obtain a polymer Deodorant.

Abstract

The invention relates to a high-efficiency deodorant. The purifier includes an air channel, and the inner surface of the air channel is coated with a polymer deodorant. The polymer deodorant is composed of 100 parts by weight of water-based polyurethane, 10 parts by weight, -25 parts by weight of polyacrylamide, 15-80 parts by weight of nano-zinc oxide, 0.03-0.3 parts by weight of hydrogen peroxide and 3-10 parts by weight of modified nano-tantalum oxide. The solid content of the water-based polyurethane is Content is 5‑15%. The polymer deodorant of the present invention can efficiently degrade a variety of odorous organic matter.

Description

technical field [0001] The invention relates to a high-efficiency deodorant. Background technique [0002] Ammonia, nicotine, aerosols, PM2.5, polonium-210, etc. in the home environment are the most harmful and serious indoor air pollution, and are a major cause of death in the world; the odor of formaldehyde brought in by home decoration is irritating , sensitization, mutagenesis and other negative effects, which greatly endanger people's health; musty smell in the environment, kitchen odor (oil fume, sour smell, etc.), toilet odor, etc. will greatly affect the quality of home furnishing, and the bacterial spores carried in it, Rancid oil, methyl mercaptan, methylamine, NH3, etc. cause disease and cancer to people. [0003] In the prior art, the plant absorption method is often used, for example, plants such as tiger Piran, Chlorophytum, tropical fruits such as pineapples, tea leaves or pomelo peels are used to remove odors. It has the characteristics of absorption and aro...
