Embodiment 1

[0030] Such as figure 1 As shown, an electrospinning receiving device includes a drum 1. The surface of the drum 1 is provided with a plurality of hollow protrusions 2, and one side of the protrusions 2 is in contact with the drum 1. The contact surface of 1 can be connected to the inside of the drum 1. The opposite sides of this surface are closed. Except for the two sides, the other surfaces are provided with holes. The inside of the drum 1 is a hollow structure, one end is connected with a high-temperature steam generator and the other end is closed. The steam is discharged from the holes of the protrusion 2, which can etch the surface of the substrate in contact with it, and increase the surface roughness of the substrate. The discharge speed depends on the cross-sectional area of ​​the roller, the area of ​​the small hole and the feeding speed.

[0031] The cross section of the roller 1 is circular and the cross-sectional area is 100 cm 2 , The length L1 is 30cm, and the mate...

Embodiment 2

[0033] Similar to the electrospinning receiving device of embodiment 1, the difference is: the cross section of the drum 1 is circular, and the cross-sectional area is 200 cm 2 , The length L1 is 40cm, and the material is copper; the wall thickness T1 of the drum is 4cm; the protrusions 2 are regularly arranged on the surface of the drum, and the shape of the protrusions is triangular prism, and the material is the same as that of the drum; The height H of 2 is 0.6mm, and the cross-sectional area is 0.5mm 2 , The thickness T2 is 0.1mm, and the distance D between two adjacent protrusions on the roller is 0.55mm. The shape of the hole is square with an area of ​​0.08mm 2 .

Embodiment 3

[0035] Similar to the electrospinning receiving device of embodiment 1, the difference is that: the cross section of the drum 1 is circular, and the cross-sectional area is 300 cm 2 , The length L1 is 60cm, and the material is aluminum; the wall thickness T1 of the drum is 6cm; the protrusions 2 are regularly arranged on the surface of the drum, and the shape of the protrusions is a triangular prism, and the material is the same as that of the drum; The height H of 2 is 0.7mm, and the cross-sectional area is 1mm 2 , The thickness T2 is 0.15mm, and the distance D between two adjacent protrusions on the roller is 0.6mm. The shape of the hole is square and the area is 0.7mm 2 .

Abstract

The invention provides an air filtering material capable of releasing negative ions and a preparation method of the air filtering material. The air filtering material capable of releasing the negative ions is characterized by comprising a base material and a nanometer fiber layer arranged on the base material, wherein the base material is of a mesh shape; the nanometer fiber layer comprises nanometer fiber, a water-absorption and water-retention substance and a negative ion functional substance. The preparation method of the mesh-shaped negative ion filtering material is characterized in that a high water-absorption and water-retention polymer and the negative ion functional substance are mixed and prepared into a solution, and then spinning is performed; or the high water-absorption and water-retention polymer and the negative ion functional substance are put into different liquid storage devices for simultaneous spinning. The mesh-shaped negative ion filtering material has the advantages of high fiber and base material combining strength, high negative ion release quantity, high device operability and the like, and has wide application prospects in the aspect of filtering materials for air purifiers, window screens and masks.

Description

Technical field [0001] The invention belongs to the field of nanofibers, and relates to an air filter material capable of releasing negative ions and an electrostatic spinning method thereof, and in particular to an air filtering material capable of releasing negative ions, an electrostatic spinning method and an electrostatic spinning method thereof. Background technique [0002] The particulate matter in the smog poses a great threat to human health. The smog pollution problem has caused the premature death of about 3 million people worldwide, and it is urgent to take effective measures to protect it. The filter material with the function of releasing negative ions can use negative ions as purification factors to actively purify the surrounding air, thereby effectively protecting human health. Existing negative ion filter materials all have the problems of low negative ion release and poor purification effect durability, and cannot simultaneously meet people's performance requi...
