Abstract
Various pollutants exist in the production process of industrial enterprises, and the polluted air contains cation aerosol, anion aerosol and neutral dust, so that a mask which is good in air tightness and air permeability and can be used by people is urgently needed in the market at present, and a disposable mask sold in the market, either electret negative electricity or electret positive electricity can only play a role in charged dust and neutral dust; the technical scheme of the invention is that the mask comprises a plurality of layers of mask cloth, a nose bridge strip and a mask belt, and is processed by a welding process, wherein the plurality of layers of mask cloth comprise an outer layer, an electret negative layer, an insulating layer, an electrostatic shielding layer, an insulating layer, an electret positive layer and an inner layer. Can effectively filter harmful substances in air such as cation aerosol, anion aerosol, neutral dust, haze, dust mites, viruses, bacteria, formaldehyde and the like, provides powerful guarantee for healthy traveling of people, and has wide market prospect.
Description
Technical Field
The invention relates to a multilayer protective mask, in particular to the use of medical institution, civil use and industrial protection.
Background
Various pollutions exist in the production process of industrial enterprises, and the dirty air contains cation aerosol, anion aerosol and neutral dust, so that the existing market urgently needs a mask which is good in air tightness and air permeability and can be used by people.
Disposable masks sold in the market, either electret negative or positive, can only work with one kind of charged and neutral dust.
Disclosure of Invention
The invention aims to provide a mask which is good in breathability and air tightness and can be used by people.
The technical scheme of the invention is that the mask is composed of a plurality of layers of mask cloth, a nose bridge strip and a mask belt and is processed by utilizing a welding process.
The multilayer mask cloth is composed of an outer layer, an electret negative layer, an insulating layer, an electrostatic shielding layer, an insulating layer, an electret positive layer and an inner layer.
The outer layer is spun-bonded non-woven fabric.
The electret negative electric layer is melt-blown non-woven fabric with electret negative electricity.
The insulating layer is spun-bonded non-woven fabric, cotton cloth or gauze.
The electrostatic shielding layer is non-woven fabrics, cotton fabrics or gauze impregnated with conductive carbon black or printed with conductive carbon black.
The electret positive electricity layer is melt-blown nonwoven fabric with electret positive electricity.
The inner layer is skin-friendly spun-bonded non-woven fabric, cotton cloth or gauze.
The invention has the beneficial effects that: can effectively filter harmful substances in air such as cation aerosol, anion aerosol, neutral dust, haze, dust mites, viruses, bacteria, formaldehyde and the like, provides powerful guarantee for healthy traveling of people, and has wide market prospect.
