Abstract

The invention discloses a formaldehyde adsorbent for air purification and a preparation method and application thereof. The formaldehyde adsorbent is prepared from, by mass, 56-62 parts of calcium carbonate, 11-16 parts of hydrated titanium dioxide, 32-37 parts of ethylene glycol, 8-12 parts of dictamnolactone, 5-7 parts of aluminum phosphate and 87-92 parts of deionized water. The formaldehyde adsorbent takes calcium carbonate as a main component, through the combined action of dictamnolactone, aluminum phosphate, hydrated titanium dioxide and ethylene glycol, the formaldehyde adsorbent has a good effect on formaldehyde adsorption, the raw materials have wide sources, cost is low and the formaldehyde adsorbent is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of pollution treatment, in particular to a formaldehyde adsorbent for air purification and its preparation method and application. Background technique [0002] Formaldehyde is an important chemical raw material and is widely used in industry. Some additives (such as phenolic resin, etc.) used in various chemical building materials or products will decompose during use to produce free formaldehyde, which will be gradually released into the environment, causing certain damage to people's living environment, especially to human health. harm. Man-made panels such as plywood and particle board used in the decoration process, as well as materials such as wallpaper, wall covering and paint for decoration, will inevitably have residual formaldehyde. In recent years, with the extensive use of these decoration materials, the accompanying indoor formaldehyde pollution has always been a concern. Long-term exposure t...
