Embodiment 1

[0027] like figure 1 As shown, a kind of environmental protection mouth mask of the present invention comprises outer layer 1, filter core layer 2, skin-friendly inner layer 3, bridge of the nose strip 4 and ear band 5; Outer layer 1, filter core layer 2 and skin-friendly inner layer 3 are separately separated Independent structure, the outer layer 1 and the skin-friendly inner layer 3 form the main body of the mask through thermal bonding, and one side of the main body of the mask is provided with an opening for putting in or taking out the filter core layer 2, and the bridge of the nose 4 is fixed on the In the upper middle part of the mask main body, the ear straps 5 are bonded to both sides of the mask main body by ultrasonic.

[0028] The outer layer 1 is a woven fabric made of polyester, and the phosphate silver-loaded antibacterial agent and graphene components are added to the surface of the fiber. The added amount of the phosphate silver-loaded antibacterial agent is ...

Embodiment 2

[0037] An environmentally friendly mask includes an outer layer 1, a filter core layer 2, a skin-friendly inner layer 3, a nose bridge strip 4 and ear straps; the outer layer 1, the filter core layer 2 and the skin-friendly inner layer 3 are bonded in sequence to form a mask The main body and the left and right borders of the mask body have holes formed by hot-melt bonding, and the width of the holes is 1mm; the nose bridge strip 4 is directly packaged in the middle and upper part of the mask body; the ear straps 5 directly pass through the holes formed in the left and right boundaries of the mask body .

[0038]The outer layer 1 is a knitted fabric made of polypropylene, and the nano-zinc oxide antibacterial agent and the graphene oxide antibacterial agent are added to the inside of the fiber. The addition of the nano-zinc oxide antibacterial agent is 2.5%, and the addition of the graphene oxide antibacterial agent is 0.1%. The diameter of the fiber is 10-50 μm, and the cross...

Embodiment 3

[0047] An environmentally friendly mask includes an outer layer 1, a filter core layer 2, a skin-friendly inner layer 3, a nose bridge strip 4 and ear straps; the outer layer 1, the filter core layer 2 and the skin-friendly inner layer 3 are bonded in sequence to form a mask The main body and the left and right boundaries of the mask body have holes formed by hot-melt bonding, and the width of the holes is 10mm; the nose bridge strip 4 is directly packaged in the middle and upper part of the mask body; the ear straps 5 pass directly through the holes formed in the left and right boundaries of the mask body.

[0048] The outer layer 1 is a woven fabric made of polyamide, and the metal nano-copper antibacterial agent and the metal nano-magnesium antibacterial agent are added to the inside of the fiber. The metal nano-copper antibacterial agent is added in an amount of 2.5%, and the metal nano-magnesium antibacterial agent is added in an amount of 5%. The diameter of the fiber is ...

Abstract

The invention provides an environmentally-friendly mask, the mask comprises an outer layer, a filter element layer, a skin-friendly inner layer, a nose bridge strip and ear bands, wherein the outer layer, the filter element layer and the skin-friendly inner layer form a mask main body in sequence, the nose bridge strip is fixed at the middle upper part of the mask main body, the ear bands are fixed at the two ends of the mask main body, and fibers forming the outer layer, the filter element layer and the skin-friendly inner layer are all made of thermoplastic high polymer materials. The invention further discloses a recycling method of the mask, the abandoned mask is dried, and then a single / double-screw extruder is adopted to prepare heatable particles which can be reused. The problem that waste masks cannot be recycled is solved.

Description

technical field [0001] The invention relates to a respiratory protection device or a component of the respiratory device, in particular to an environment-friendly mask and a recycling method thereof. Background technique [0002] With the increasing demand for masks for epidemic prevention and control, air pollution, and allergen control, masks have become a necessity for personal protection in people's daily life. The main function of the mask is to provide the wearer with an air filter carrier, and it needs to meet certain filter efficiency and filter resistance. The masks currently used are basically disposable masks, which are made of non-woven fabrics prepared from polypropylene thermoplastic polymers. Polypropylene is a polymer material that is easily degraded and pulverized by ultraviolet light, but it takes a long time for the pulverized polymer to be further degraded into small molecules or low molecules digested by microorganisms. Generally speaking, masks in spe...
