Abstract

The invention discloses a formaldehyde removal material containing dopamine and a preparation method of the formaldehyde removal material, belonging to the field of formaldehyde removal. The formaldehyde removal material comprises the following raw material components in parts by weight: 6 to 15 parts of dopamine, 6 to 20 parts of acid, 40 to 60 parts of a carrier and 50 to 90 parts of distilled water. Specifically, the formaldehyde removal material comprises the following raw material components in parts by weight: 6 parts of the dopamine, 6 parts of the acid, 40 parts of the carrier and 50 parts of the distilled water; or 15 parts of the dopamine, 20 parts of the acid, 60 parts of the carrier and 90 parts of the distilled water. The carrier can be any one or a mixture of more than one selected from the group consisting of activated carbon, aluminum oxide, silica gel, a porous molecular sieve, diatomite, ceramic and the like. The prepared dopamine-containing formaldehyde removal material can quickly remove formaldehyde at room temperature, and is good in formaldehyde removal effect, large in adsorption capacity and free of secondary pollution.

Description

technical field [0001] The invention belongs to the field of preparation of formaldehyde-removing materials, and relates to a dopamine-containing formaldehyde-removing material and a preparation method thereof. Background technique [0002] People spend more than 80% of their time indoors on average every day, and the relationship between indoor air quality and human health is quite close. In recent years, the problem of indoor environmental pollution has become increasingly prominent, endangering human health and reducing human immunity. The most prominent pollutant in indoor environmental pollution is formaldehyde. Floor leather, floor tiles, chemical fiber carpets, plastic wallpapers, thermal insulation materials, urea-formaldehyde resin adhesives, and fiberboards and plywoods made of adhesives are commonly used indoors. Made of furniture, etc. can release formaldehyde. [0003] The current methods for removing formaldehyde are adsorption, photocatalysis, and noble meta...
