Problems solved by technology

[0003] The adsorption method mostly uses activated carbon, clay, molecular sieve and corresponding modified substances as adsorption materials to adsorb and remove odor substances, which has wide applicability, but has the disadvantages of low efficiency of passive adsorption and removal, and needs to be used in combination with purification equipment (with fan) In order to achieve a better removal effect; fragrance masking method is currently a more commonly used method for removing odors, using aromatic components or plant, fruit and other extracts to cover up odors, but there are shortcomings such as treating the symptoms but not the root cause. It is diluted rather than removed, and the harm to the human body has not been eliminated; the plant absorption method mostly uses plants such as tiger Pilan and Chlorophytum, tropical fruits such as pineapples, tea leaves or grapefruit peels to achieve odor removal, which has the characteristics of absorption and aroma masking. , cheap and effective, but the removal speed is relatively slow; the chlorine dioxide oxidation method is more common in odor-removing materials, and the strong oxidizing property of chlorine dioxide itself can achieve the removal of odorous substances, but the removal is not complete, and it is ineffective for many odorous substances , its own toxicity and other disadvantages; the ozone oxidation method is similar to the chlorine dioxide oxidation method, and has a good removal effect on the odor caused by some organic volatile components, but the ozone itself also has a relatively large odor, and has certain damage to the human body Emerging photocatalytic methods mostly use photocatalyst materials to achieve the effect of removing odors under the excitation of light (mostly ultraviolet light is effective), and generally have a certain removal and killing effect on some organic matter and bacteria. source, so the practicality is extremely limited

Abstract

The invention relates to a green environmentally-friendly polymer deodorant capable of efficiently degrading a plurality of odorous organic substances. A purifier includes an air passage, the inner surface of the air passage is coated by the polymer deodorant, and the polymer deodorant is prepared from 100 parts by weight of a water-based hyperbranched polymer, 1-5 parts by weight of polyethyleneglycol, 6-30 parts by weight of porous silicon dioxide, 0.03-0.3 part by weight of hydrogen peroxide and 3-10 parts by weight of modified nano niobium oxide, wherein the solid content of the water-based hyperbranched polymer is 5-15%. The green environmentally-friendly polymer deodorant provided by the invention can efficiently degrade the plurality of odorous organic substances.

Description

technical field [0001] The invention relates to a green environment-friendly polymer deodorant capable of efficiently degrading various odorous organic substances, and also relates to the application of the green environment-friendly polymer deodorant capable of efficiently degrading various odorous organic substances in air purification. Background technique [0002] The peculiar smell in the home environment not only brings bad sensory stimulation to people, but also has great harm to the body. For example, second-hand smoke contains more than 4,000 harmful chemicals and dozens of carcinogens such as tar, ammonia, nicotine, suspended particles, PM2.5, and polonium-210. Indoor air pollution is a major cause of death in the world; formaldehyde odor brought by home decoration has negative effects such as irritation, allergies, and mutagenesis, which greatly endangers people's health; musty smell in the environment, kitchen odor (oil smoke, sour smell) Odor, etc.), toilet odo...
