Cold catalyst-containing novel compound air purifying particle and preparation method thereof

Abstract

The invention discloses a cold catalyst-containing novel compound air purifying particle and a preparation method thereof, and belongs to the technical field of air purification. The cold catalyst-containing novel compound air purifying particle comprises Baina soil with a 2:1 layered chain-shaped crystal structure, and the Baina soil has a unique microstructure and electric charge properties, sothat most of harmful gases with polarity in air can be adsorbed, secondarily, sepiolite, medical stone and diatom are relatively large in porosity, so that a stable structure and long-lasting adsorbability are achieved by cooperation of the sepiolite, the medical stone and the diatom, and the air purifying particle is strong in adsorbability, and relatively strong in rheological property and catalytic performance, and meanwhile, a cold catalyst contained in the formula can catalyze formaldehyde to react with oxygen in air, and the cold catalyst itself does not participate in the reaction directly in the process of catalytic reaction, so that the decomposition effect of the air purifying particle on formaldehyde is effectively improved, a service cycle of the air purifying particle is prolonged, and formaldehyde is effectively decomposed for a long term.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a novel composite air purification particle containing a cold catalyst and a preparation method thereof. Background technique [0002] Building materials for newly renovated homes, indoor furniture, painted floorboards, and newly bought cars will all produce toxic gases such as formaldehyde, benzene, xylene, radon, etc., which are harmful to human health, and these toxic gases will stay in people for a long time. In the living environment, formaldehyde is an important part of adhesives, so everything that involves adhesives, including wood-based panels, paints (mainly wall bases), carpets, and furniture will contain formaldehyde. If a single item exceeds the standard, it will inevitably cause The air quality is not up to standard. It is also worth noting that even if each product is within the scope, if there are too many building materials containing formaldehyde in th...

Problems solved by technology

The biggest disadvantages of these methods and products are: incomplete governance, low efficiency, easy to produce secondary pollution, etc.

The existing indoor formaldehyde removal products on the market are mainly activated carbon and carbon synthetic particles. These products mainly use activated carbon and attapulgite as the main raw materials. They have the following disadvantages: the validity period is short, only one month, but the time for formaldehyde to volatilize indoors It is 3-15 years, therefore, due to the limited adsorption of activated carbon and carbon synthetic particles, it is easy to be saturated, and there is a disadvantage of secondary volatilization

[0004] The air purifiers that effectively adsorb formaldehyde in the prior art are partly made of pure plants, and some are made of chemical reagents; for the air purifiers that effectively adsorb formaldehyde made of pure plants, although they will not affect the body, they can be obtained from plants. The process of extracting components is complicated, and the removal effect on formaldehyde is limited; for the air purifier that effectively absorbs formaldehyde configured with chemical reagents, although the production process is simple and the removal effect is good, the chemical reagents themselves have certain toxicity and have certain effects on the human body. In the process of treating pollutants, it may also cause secondary pollution
