Problems solved by technology

[0003] Both industrial waste gas and automobile exhaust gas contain a lot of dust. Due to the air circulation, there will be a lot of dust even in the room. The dust is not only harmful to the human respiratory tract, but also a carrier of bacteria and mites. Long-term exposure to such conditions is not good for human health.
[0004] At present, there are indoor purifiers on the market, but the functions are relatively single

Abstract

The invention discloses a method for preparing indoor air purification filter elements. The indoor air purification filter elements comprise outer polytetrafluoroethylene microporous membranes and inner formaldehyde absorption cores. The method includes (1), acquiring calcium peroxide, activated zeolite molecular sieves, calcium oxide, calcium carbonate, polyvinylpyrrolidone and water according toa mass ratio of 5:4:2:1:1:10 and stirring the calcium peroxide, the activated zeolite molecular sieves, the calcium oxide, the calcium carbonate, the polyvinylpyrrolidone and the water to obtain mixtures; (2), adding adhesive into the mixtures and uniformly mixing the adhesive and the mixtures with one another to obtain standby coating; (3), placing porous mold plates in the standby coating and airing the porous mold plates after 10-15 hours to obtain the cores; (4), carrying out hot-pressing coating on the polytetrafluoroethylene microporous membranes outside the cores to obtain the indoor air purification filter elements. A biological mass ratio of the adhesive to the mixtures is 2-3:4-7. The method has the advantages that the outer polytetrafluoroethylene microporous membranes of the indoor air purification filter elements prepared by the aid of the method have small pore diameters, and dust can be effectively removed; the cores contain the calcium peroxide and the activated zeolite molecular sieves, accordingly, formaldehyde can be removed, and other harmful gas and odor further can be absorbed.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a preparation method of an indoor air purification filter element. Background technique [0002] With the improvement of people's living standards, home improvement is becoming more and more popular. However, the harm of home decoration pollution that comes with it cannot be ignored. Formaldehyde is one of the main home improvement pollution. The main hazard of formaldehyde is the stimulation of the skin and mucous membranes. Formaldehyde is a toxic substance in the original plasma, which can be combined with proteins. When inhaled at high concentrations, severe respiratory tract irritation, edema, eye irritation, and headache occur; formaldehyde is sensitizing. Direct skin contact Formaldehyde can cause allergic dermatitis, pigmentation, necrosis, and can induce bronchial asthma when inhaling high-concentration formaldehyde; formaldehyde also has mutagenic effects, and ...
