A kind of anti-smog mask with konjac glucomannan film

Abstract

The invention relates to a konjac glucomannan membrane haze-prevention mask. A mask body of the konjac glucomannan membrane haze-prevention mask is composed of four layers which specifically include the first layer, namely, the outmost layer, made of non-woven fabric, the second layer made of a konjac glucomannan porous membrane, the third layer made of a konjac glucomannan nanometer porous membrane, and the fourth layer, namely, the layer in contact with the face, made of non-woven fabric. With natural polymer polysaccharide, namely, konjac glucomannan, serving as the main ingredient, the konjac glucomannan membrane haze-prevention mask has various characteristics of hydrophilia, the thickening characteristic, stability and the like. In recent years, natural polymer compounds are widely applied to the material field, and many problem emerging on material safety are solved. The technology of preparing high-quality nanometer porous membranes with plant polysaccharide serving as the raw materials become a hot point in recent years; according to the method, the special gel property of konjac glucomannan is utilized, and the konjac glucomannan nanometer porous membrane is obtained through application of the electric field technology, and has great application potential in the material field. The konjac glucomannan membrane haze-prevention mask has higher indexes such adsorption performance, safety, raw material price and potential markets than those of other masks on the market, and can be selected by mass consumers as high-quality haze-prevention masks.

Description

technical field [0001] The invention relates to a protective tool for the respiratory system, in particular to a konjac glucomannan film anti-fog mask, which belongs to the field of sanitary products. Background technique [0002] Haze is composed of dust, sulfuric acid, nitric acid, organic hydrocarbons and other particles in the air, especially PM2.5 (particulate matter with an aerodynamic equivalent diameter less than or equal to 2.5 microns) is considered to be the "culprit" of haze weather ". The U.S. Environmental Protection Agency released the "Comprehensive Scientific Assessment Report on Air Particulate Matter" in 2009, pointing out that there are sufficient scientific research results to prove that atmospheric fine particles can absorb a large number of carcinogens and genotoxic mutagenic substances, which can bring negligible negative effects to human health. Impacts include increasing mortality, exacerbating chronic diseases, exacerbating respiratory and cardiac...
