Durable anti-haze gauze net, and production device and production method thereof

Abstract

The invention relates to an air filtering material and aims to provide a durable anti-haze gauze net and a production device and production method thereof. The gauze net comprises a base gauze net anda filter layer, wherein a resin coating is located between the base gauze net and the filter layer; the filter layer is formed by alternate stacking of nanofiber layers and microfiber layers, the lowermost layer of the filter layer is one nanofiber layer, and the uppermost layer of the filter layer is one microfiber layer; the diameters of fibers in the nanofiber layers are in a range of 100 to 400 nanometers, and the diameters of fibers in the microfiber layers are in a range of 1 to 10 micrometers; and tight bonding are achieved between the base gauze net and the resin coating, between theresin coating and the filter layer and between the nanofiber layers and the microfiber layers in the filter layer. The invention has the following beneficial effects: production efficiency is high; addition of composite equipment is not needed; process flow is reduced; the produced anti-haze gauze net has high light transmission and high gas permeability; a bonding area can be increased; mechanical strength and protection are provided; non-destructive bonding and high fastness are ensured; the durability of the produced gauze net is greatly improved; and nodes among fibers in the filter layerstably exist.

Description

technical field [0001] The invention relates to an air filter material, in particular to an anti-smog gauze produced by using electrostatic centrifugal spinning micro-nano fiber preparation technology and a production device and method, belonging to the field of air filtration. Background technique [0002] In recent years, with the continuous development of my country's industrialization, economic and social progress and extraordinary achievements, but the problem of air pollution has become increasingly prominent. According to a survey, some cities in my country have 100-200 days of smog in a year, which has seriously affected people's daily life and health. Haze weather is very harmful. For people suffering from asthma, chronic bronchitis, chronic obstructive pulmonary disease and other respiratory diseases, it will cause discomfort such as shortness of breath and chest tightness, which may cause lung infection or acute exacerbation. In order to prevent excessive exposur...
