Abstract

The utility model provides an electret protection respirator, which is mainly designed to solve the bad protection performance of a conventional respirator. The electret protection respirator comprises a respirator body and laces, wherein the respirator body is made of non-woven fabric or cotton cloth and polytetrafluoroethylene electret material. The electret protection respirator is characterized in that an outer layer and an inner layer of the respirator body are made of non-woven fabric or cotton cloth; polytetrafluoroethylene electret sponges or thin-film material is arranged between the outer layer and the inner layer, or polytetrafluoroethylene electret dispersion liquid is sprayed onto the respirator body so as to form a cover film after being dried; in addition, the laces are arranged at the upper and the lower parts or both sides of the respirator body, and are used for wearing. The electret protection respirator achieves excellent protection performance, the combination property of the electret protection respirator exceeds the requirements of national standard grades, and the electret protection respirator is especially suitable for being used by epidemic prevention personnel, medical staff and personnel who work and live in high dust and high pollution environment.

Description

The electret protective mask

Technical field

The utility model provides a kind of protective mask, and particularly a kind of protective mask with disinfection function belongs to healthy prevention articles for use field.

Background technology

Mouth mask is medical epidemic prevention personnel's an important protective gear; Also be that people prevent because the healthy protective articles of air pollution harm; But the mouth mask that uses now is to be processed by gauze or nonwoven mostly; Wear use through sterilization, exist to filter airborne dust weak effect, do not have problems such as the bacterial virus of killing effect.

Summary of the invention

For solving the problems referred to above that present protective mask exists; The utility model provides a kind of protective mask that adopts electret to make; This mouth mask utilizes the characteristic of electret to stop and filters airborne dust and kill the bacterial virus that is attached on the dust, have excellent protection effect.

The technical scheme that the utility model technical solution problem is taked is; The protective mask body comprises internal layer, skin and electret protective materials; It is characterized in that; Between the internal layer of protective mask body, skin or the electret filtering layer is set on the mouth mask body, utilize the dust in the electret properties of materials blocks air, kill attached to the bacterial virus on the mouth mask.

The described electret of the utility model is to polytetrafluoroethylmaterial material, and under effect of factors such as strong external electric field, polarization also can the longer-term storage electric charge.In electret, there is electrostatic field; The hole of material is similar to numerous passive collecting electrode; When airborne particulate especially submicron particle during at the hole through the electret filtering layer; Quilt is stopped or is caught under the effect of electric field force, and airborne neutral corpuscle becomes dipole because of responding to or polarizing through the electret filtering layer time, also effectively stopped.Bacterial virus has natural electret state (electronegative); Usually be attached on the dust with air borne, when they with airborne dust during through the electret filtering layer, being hunted down is blocked in outside the electret; The cell membrane that the electrostatic field that electret produces and little electric current can damage bacterial virus; Destroy the surface texture of bacterial virus, stimulate the protein variations of bacterial virus, cause bacterial virus dead.The electrostatic field of electret and little electric current also have the effect that ionized air produces anion and ozone fresh air.Therefore electret, has excellent characteristic owing to have the effect of low flow resistance, resistance dirt, sterilization aspect purifying air.

Described polytetrafluoroethylene (PTFE) is a kind of fluoroplastics, and adsorbing agent carrier is processed in its processing refinement, and the aperture of material is arranged on about the 2-5 nanometer, adopts corona method or puncture method that adsorbing agent carrier is carried out the electret technical finesse, makes it become electret.Described polytetrafluoroethylene (PTFE) adsorbing agent carrier in the body is sponge, film and dispersion liquid desciccator diaphragm material, has sterilization, acidproof, alkaline-resisting, high temperature resistant, and water insoluble and alcohol equal solvent is nontoxic, the characteristics that performance is safe and reliable.

The beneficial effect of the utility model is; Have excellent sterilization and dustproof effect; Filter efficiency to airborne submicron order powder dust particle and neutral particle is high; Extremely strong to being attached on the dust with airborne bacterial virus insect killing effect, also have the function that ionized air produces anion and ozone fresh air, air resistance is about 236Pa; The integrated protection performance class requirement that is up to state standards is specially adapted to the medical epidemic prevention personnel and the personnel of work life under high dust high pollution environment use.
