Abstract

The invention discloses an air filtration material taking bamboo fiber as the main raw material. The air filtration material comprises a three-layer compounded structure, wherein the inner-layer material is composed of bamboo pulp fibers, polylactic acid fibers and water-soluble poly(vinyl alcohol) fibers; the middle-layer material is composed of bamboo pulp fibers, wood pulp fibers and water-soluble poly(vinyl alcohol) fibers; the surface-layer is formed by coating a polymer emulsion, and slurry prepared by a pigment, a silver ion antibacterial agent, and a thickener; the thickness of the inner layer is 70-110 g / m<2>, the average pore size of the inner layer is 80-120mu m, the thickness of the middle layer is 20-60 g / m<2>, the average pore size of the middle layer is 50-70mu m, the thickness of the surface layer is 1-10mu m, and the average pore size of the surface layer is 5-20mu m. The filtration material has the characteristics of being efficient in filtering with low resistance, large in dust holding capacity, and strong in antibacterial property, and being capable of completely degrading after being discarded, and can be applied to occasions including domestic air filtration, medical air filtration, dust collectors, automobile engines, industrial dust filtering, and the like.

Description

technical field [0001] The invention relates to an air filter material for an air filter and a preparation method thereof, in particular to a novel air filter material with bamboo fiber as the main material and a preparation method thereof. Background technique [0002] A person inhales an average of about 10,000 liters of air every day. Dust in the air can cause diseases including asthma, bronchitis, and cardiovascular disease, and has become an important killer that threatens human health. Obtaining clean air through air filter materials is a common method at present, so air filter materials have a very broad market. The currently used air filter paper is mainly made of glass fiber materials and chemical fiber materials. After the filter paper of these materials is used and discarded, it cannot be degraded by the environment, which will cause new environmental pollution and increase a great burden on the environment. Production is an energy-intensive process. Therefore, ...
