Air purification material and preparation method thereof

Abstract

The invention relates to the field of materials, and in particular relates to an air purification material and a preparation method thereof. The air purification material comprises an adsorption inner layer and a purification outer layer, wherein the adsorption inner layer comprises the following components in parts by weight: 30 to 50 parts of montmorillonite, 10 to 15 parts of sepiolite, 0.1 to 0.5 part of an acidulant, 10 to 30 parts of activated carbon and 10 to 40 parts of a foaming agent aqueous solution with a mass fraction of 2 to 6%. The purification outer layer comprises 1 to 3 parts by weight of titanium dioxide, 0.02 to 0.1 part by weight of manganese dioxide, 5 to 8 parts by weight of zinc nitrate, 1 to 5 parts by weight of bis-hexamethylene triamine, 1 to 5 parts by weight of fiber, 2 to 5 parts by weight of aqueous cationic polyurethane, 0.5 to 0.8 part by weight of sodium carboxymethylcellulose and 10 to 40 parts by weight of the foaming agent aqueous solution with a mass fraction of 2 to 6%. The air purification agent prepared by the method has strong purifying capacity, does not generate secondary pollution, and has sterilization and bacteriostasis effects.

Description

technical field [0001] The invention relates to the field of materials, in particular to an air purification material and a preparation method thereof. [0002] technical background [0003] The use of man-made boards (plywood, particle board, fiberboard, etc.) and decorative materials has brought a certain degree of indoor decoration pollution. Although the environmental protection of related furniture and decorative products has become more stringent, consumers tend to choose more environmentally friendly products, and indoor pollution has increased. There is some control, but there is no guarantee that there will be no release of volatile organic compounds (VOCs). The sources of VOC in the indoor environment are complex and there are many types. The concentration of a single substance may be relatively low, but the total amount is large, and it accumulates to a certain concentration in a relatively closed space, which is likely to cause harm or discomfort to the human body...

AI Technical Summary

Problems solved by technology

Spray products can quickly remove some pollutants in the air, but they cannot target complex types of VOCs, and the effect is not long-lasting. Frequent use is required, especially for long-lasting pollution sources, such as wood-based panels and oil-based paint products.

Pure adsorption products, such as modified activated carbon, belong to pure adsorption, and the cost is relatively high. Recycling requires desorption and regeneration, which is difficult for civilian use
