Abstract

A high-performance formaldehyde adsorbent is prepared from components in parts by weight as follows: 60-80 parts of modified activated carbon, 15-30 parts of sepiolite, 10-20 parts of zeolite, 5-10 parts of microcrystalline cellulose, 10-20 parts of diatomaceous earth, 15-30 parts of a polyethylene polyamine polymer, 1-4 parts of polyethylene glycol, 0.5-2 parts of nano-titania and 0.5-2 parts ofnano-zinc peroxide. A preparation method of the high-performance formaldehyde adsorbent comprises the following steps: the polyethylene polyamine polymer and polyethylene glycol are mixed, deionized water is added for dilution, and a solution a is obtained; then the modified activated carbon, the sepiolite, the zeolite, microcrystalline cellulose, the diatomaceous earth, nano-titania and nano-zincperoxide are added to the solution a, and a thermal insulation reaction is performed; vacuum drying is performed, and the adsorbent is obtained. The prepared high-performance formaldehyde adsorbent has excellent formaldehyde removal performance, and tests prove that formaldehyde degradation rate of the formaldehyde adsorbent within 24 h reaches 99% or higher.

Description

technical field [0001] The invention relates to the technical field of adsorbent materials, in particular to a high-performance formaldehyde adsorbent and a preparation method thereof. Background technique [0002] Indoor environment, due to the widespread use of decoration materials and furniture, air pollutants accumulate in confined spaces for a long time. Living in this environment for a long time will pose a serious threat to human physical and mental health, and formaldehyde is one of the most harmful pollutants. According to the investigation of indoor formaldehyde content by a large number of scholars, it is found that the formaldehyde content in the living environment in most areas has already exceeded the limit of 0.10mg / m2 in my country's indoor air quality standards. 3 , and even after decoration of new houses in some areas, the amount of indoor formaldehyde exceeds the standard value by more than ten times, and the harm it poses is self-evident. Therefore, the...
