Problems solved by technology

People have done a lot of research on air purification and developed various materials with the function of purifying air. At present, the rubber powder used in indoor purification itself contains organic volatiles such as formaldehyde, and the microporous characteristics of diatom mud also It will be sealed by rubber powder and cannot perform the adsorption function, resulting in low purification efficiency

Abstract

The invention discloses a preparation method of a composite material for high-efficiency purification of indoor air. The preparation method comprises the following steps: uniformly stirring tourmalinepowder, nano-vermiculite powder, nano-diatomite and talcum powder, adding modified fir powder, uniformly mixing, calcining, grinding and then adding alumina powder, oxidized starch, microcrystallinecellulose, bamboo charcoal fibers, polyurethane resin and natural perfumes, uniformly mixing and granulating to obtain the composite material for the high-efficiency purification of the indoor air. The composite material obtained by the invention can remove organic volatiles such as formaldehyde, toluene, xylene, sulfur dioxide and VOC, has a very good air purifying function, can be applied to automobile air filter element particles, an air purifying particle packet or a refrigerator deodorant, and is high in purification efficiency, free of toxicity and pollution, can be recycled and is low in cost.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a preparation method of a composite material for efficiently purifying indoor air. Background technique [0002] International environmental protection experts have listed "indoor air pollution" as the third generation of air pollution after "soot type" and "photochemical smog type" pollution. People have done a lot of research on air purification and developed various materials with the function of purifying air. At present, the rubber powder used in indoor purification itself contains organic volatiles such as formaldehyde, and the microporous characteristics of diatom mud also It will be sealed by rubber powder and cannot perform the adsorption function, resulting in low purification efficiency. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing a composite ...
