Abstract
A kind of protective mask of chitosan-containing, is made up of mask body and ear-hang, and the mask body is formed by four layers from outside to inside, and first layer is bed of cloth, and the second layer is melt-blown nonwoven layer of cloth, and third layer is chitosan layer, and the 4th layer is bed of cloth.By protective mask provided by the utility model, second layer melt-blown nonwoven layer of cloth can be crossed in air filtering in mask body bulky grain dirt；Third layer chitosan layer is moistened in exhalation under conditions of gas, chitosan cation can adsorb the particulate matter with anion that diameter in little particle is less than 0.3 micron, repel diameter and be less than 0.3 micron of the particulate matter with cation, make it that there is protective action to the finely ground particle substance below 0.3 micron of diameter；First layer and the 4th layer of dirt and saliva of buccal cavity dipping that can be effectively prevented using cotton or degreasing cotton gauze material in air, avoid reducing melt-blown nonwoven layer of cloth and the filter effect of chitosan layer in mask body 1, while be also avoided that increase respiratory resistance.
Description
Technical field
The utility model belongs to public appliance health field, more particularly to a kind of protective mask of chitosan-containing.
Background technology
Haze pollution is weather contamination phenomenon relatively conventional at present, and PM2.5 refers to that aerodynamics is worked as in surrounding air
The particulate matter that diameter is less than or equal to 2.5 microns is measured, it can be suspended in air the long period, and content concn is got in atmosphere for it
Height, it is more serious just to represent air pollution.Although PM2.5 is the component that content is seldom in earth atmosphere composition, it is to air
Quality and visibility etc. have important influence.Compared with thicker Atmospheric particulates, PM2.5 particle diameters are small, and area is big, and activity is strong,
Poisonous and harmful substances, such as heavy metal, microorganism etc. are easily attached, and residence time length, fed distance in an atmosphere is remote, because
And the influence to health and atmosphere quality is bigger.
The medical and civilian mouth mask of existing routine can not effectively resist these fine particulates, these small fine graineds
Thing still is able to enter nasal cavity through mouth mask, therefore conventional mouth mask does not have the protective action to fine particulates substantially.
Therefore, need a kind of mouth mask that can effectively protect PM2.5 of research and development badly, prevent a series of exhale occur in haze weather
Inhale the diseases such as road infection.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of protective mask of chitosan-containing, by mask body
Formed with ear-hang, the mask body is formed by four layers from outside to inside, and first layer is bed of cloth, and the second layer is melt spraying non-woven fabrics
Layer, third layer is chitosan layer, and the 4th layer is bed of cloth.
Wherein, the material of the cloth is cotton or degreasing cotton gauze.
Wherein, the chitosan layer is chitin fiber nonwoven layer.
Wherein, the chitin fiber non-woven fabrics is needle punched non-woven fabrics.
Wherein, the aperture of the melt-blown nonwoven layer of cloth is 0.2 ~ 0.5 micron.
Preferably, the aperture of the melt-blown nonwoven layer of cloth be 0.25 micron, 0.3 micron, 0.35 micron, 0.4 micron, 0.45
Micron.
Wherein, the thickness of the melt-blown nonwoven layer of cloth is 0.2 ~ 0.4 millimeter.
Preferably, the thickness of the melt-blown nonwoven layer of cloth is 0.25 millimeter, 0.3 millimeter, 0.35 millimeter.
Wherein, the aperture of the chitosan layer is 0.2 ~ 0.5 micron.
Preferably, the aperture of the chitosan layer is 0.25 micron, and 0.3 micron, 0.35 micron, 0.4 micron, 0.45 is micro-
Rice.
Wherein, the thickness of the chitosan layer is 0.2 ~ 0.4 millimeter.
Preferably, the thickness of the chitosan layer is 0.25 millimeter, 0.3 millimeter, 0.35 millimeter.
The beneficial effects of the utility model：
A kind of protective mask gathered containing shell provided by the utility model, second layer melt-blown nonwoven layer of cloth 102 in mask body
The bulky grain dirt that can be crossed in air filtering；Third layer chitosan layer is under conditions of exhalation moistens gas, chitosan cation
The particulate matter with anion that diameter in little particle is less than 0.3 micron can be adsorbed, repels band sun of the diameter less than 0.3 micron
The particulate matter of ion, make it that there is protective action to the finely ground particle substance below 0.3 micron of diameter；First layer and the 4th layer are adopted
The dirt and saliva of buccal cavity dipping in air can be effectively prevented with cotton or degreasing cotton gauze material, avoids reducing mask body
The filter effect of middle melt-blown nonwoven layer of cloth and chitosan layer, while also it is avoided that increase respiratory resistance.
