Abstract

The invention discloses a micropore large-surface material used for adsorbing volatile organic pollutants. The micropore large-surface material is prepared from the following raw materials in a formula: 15 to 30 parts of polyhydroxyl polyurethane, 20 to 35 parts of polyacrylamide, 1 to 3 parts of a catalyst, 3 to 7 parts of an initiator, 15 to 30 parts of a foaming agent, 1 to 3 parts of a curing agent, 2 to 4 parts of a preservative, 3 to 5 parts of a penetrating agent, 20 to 30 parts of a solvent and 11 to 15 parts of nano active carbon; selection and preparation methods of the material are provided according to the formula. The method is simple and convenient, technological conditions are moderate, and the production cost is low; the structure of the material is stable and is not damaged by high temperature; the micropore large-surface material has good temperature resisting performance and good corrosion resistance; the adsorption property of resin and active carbon is sufficiently utilized, so that the adsorption effect is greatly improved and the adsorption range is wide.

Description

technical field [0001] The invention belongs to the technical field of treatment of volatile organic pollutants, and in particular relates to a microporous large-surface material used for adsorption of volatile organic pollutants. Background technique [0002] The problem of environmental pollution is one of the three focal issues of concern in the world today. It includes not only the large outdoor environment, but also the pollution of small indoor environments that are closely related to people's lives and directly related to personal health. According to a study in the United States, the pollution level of indoor air is three to five times more serious than outdoor air, and in special cases, it can be up to one hundred times; indoor air can detect hundreds of volatile organic compounds (VOC), of which several Ten are carcinogens. People spend most of their life indoors. Therefore, the indoor air quality is directly related to human health. Indoor environmental polluti...
