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...
