Composite for removing pollutants in air

Abstract

The invention belongs to the technical field of air sterilization and disinfection, and particularly discloses a composite for removing pollutants in air. The composite is prepared from, by weight, 10-20 parts of activated carbon, 5-10 parts of bentonite, 4-6 parts of sepiolite, 10-20 parts of gelatin, 4-8 parts of chitosan, 5-20 parts of plant extract, 1-5 parts of citric acid, 1-5 parts of sodium citrate, 0.5-2 parts of a thickener and 1-3 parts of spice. All the ingredients of the composite have a synergistic effect, the activated carbon, the bentonite and the sepiolite are added, so that the composite is of a porous structure, and thus the composite has ultrahigh adsorption capacity and can absorb the pollutants such as nicotine, tar and PM 2.5 in air; the plant extract can also absorband break down the nicotine and the like which are produced by smoking, accordingly, the accumulation amount of the nicotine, the tar and the PM 2.5 in air is reduced, the pollutants produced by smoking in indoor air are removed as much as possible, and harm of secondhand smoke to passive smokers is reduced.

Description

technical field [0001] The invention belongs to the technical field of air disinfection and sterilization, and specifically discloses a composition for eliminating pollutants in the air. Background technique [0002] "Smoking is harmful to health" and "no smoking in public places" are well-known and commonplace things, but there are still many people smoking in public places, especially when traveling by car, the carriage is in a closed state, the air is not smooth enough, and the surrounding When someone smokes, passive smokers suffer greatly. Second-hand smoke is no less harmful to passive smokers than active smokers, especially to children. Surveys show that in China, the main victims of passive smoking are women and children. Although they do not smoke themselves, they are often exposed to second-hand smoke from others at home and in public places. In addition, workplaces, conference venues, etc., are often places where second-hand smoke is rampant. Although not direct...

Problems solved by technology

At present, the types of masks sold on the market mainly include cotton yarn masks, non-woven fabric masks, activated carbon masks, medical masks, and N95 anti-particle masks, etc. Although cotton yarn masks and non-woven fabric masks have good air permeability and can block large particles of dust, but It has almost no effect on chemical substances such as PM2.5 and nicotine; although activated carbon masks can effectively absorb harmful gases such as benzene and formaldehyde in the air, their adsorption is weak and they cannot effectively prevent dust; medical masks use strict disinfection procedures Made of medical gauze, it can prevent poison and sterilize, but it has poor fit and cannot play a dustproof role; N95 and other anti-particle masks can effectively prevent and control tiny particles such as PM2.5 to a certain extent, but the air permeability of these masks They are all poor, and the breathing resistance is large. Long-term wearing may cause poor breathing. For people with respiratory diseases, this kind of mask is not suitable for long-term wearing, and the high cost of this kind of mask and the inability to clean it also affect its popularization and application.
