Abstract

The invention discloses a preparation method of an efficient formaldehyde purification material suitable for filling an air purifier. The preparation method comprises: (1) weighing active carbon, using an equal amount impregnation method, taking deionized water according to the water capacity of the active carbon, weighing graphene oxide and dicyandiamide, adding to the metered deionized water, and stirring until fully dissolving to prepare an impregnating liquid; and (2) uniformly pouring the prepared impregnating liquid onto the active carbon carrier, continuously stirring until fully impregnating, loading the mixture into a sealed bag, standing for 1-4 h, and drying at a temperature of 80-160 DEG C to prepare the purification material. According to the present invention, the active carbon is selected as the carrier material, the high-performance material A and the inorganic salt B are used as the active components, the active components are loaded onto the carrier material through impregnating, the drying is performed at a certain temperature to prepare the catalyst, and the formaldehyde removing effect is significant after the air purifier is filled with the prepared carbon plate.

Description

technical field [0001] The invention belongs to the field of preparation of purification materials, in particular to a high-efficiency formaldehyde purification material suitable for filling air purifiers and a preparation method. Background technique [0002] Formaldehyde (HCHO) is a common indoor air pollutant with the characteristics of wide sources, high toxicity and long incubation time. With the development of social economy and the improvement of residents' living standards, the health problems caused by it have attracted more and more attention. All kinds of formaldehyde protective materials that emerged as a result have also been asked in the world. With the release of the GB / T18801-2015 air purifier standard in 2016, there are clear requirements for formaldehyde purification capabilities. Many formaldehyde purification materials on the market cannot meet the requirements when filled into air purifiers. It is imperative to study an efficient formaldehyde purificati...
