In the fresh air system of buildings, air filtration materials are used to purify and filter the inflowing air. Therefore, air filtration materials are an important air treatment product.

[0003] The above-mentioned and existing technologies have the following defects: During the operation of the air filtration material, static electricity is likely to be generated inside the air filtration material. Since static electricity will cause a large amount of dust to adhere to the surface of the air filtration material, the surface of the air filtration material will be blocked, resulting in the situation that air is difficult to flow through the air filtration material normally, reducing the filtration efficiency of the air filtration material.

[0004] Therefore, an anti-static composite air filtration material is proposed. Summary of the Utility Model

[0008] Preferably, anti-puncture layers are adhesively bonded to both sides of the filtration layer, and the anti-puncture layers are aramid fiber woven layers.

[0011] The effects achieved by the above components are as follows: By providing a wear-resistant layer made of polypropylene, the filter layer can be protected, thereby extending the service life of the filter layer.

[0012] Preferably, a plurality of ventilation holes are formed on the surface of the wear-resistant layer.

[0013] The effects achieved by the above components are as follows: The ventilation holes can ensure that air can flow through the wear-resistant layer and then through the filter layer normally.

[0014] Preferably, a release film is adhered to the side of the wear-resistant layer away from the puncture-resistant layer, and the release film is a PET film.

[0015] The effects achieved by the above components are as follows: The release film can shield and protect the wear-resistant layer when the filter layer is not in use.

[0016] Preferably, a plurality of easy-tear grooves are formed on the surface of the release film.

[0017] The effects achieved by the above components are as follows: By forming easy-tear grooves on the surface of the release film, the release film can be torn along the easy-tear grooves, thus facilitating the segmentation of the filter layer.

[0019] The effects achieved by the above components are as follows: The edge sealing strips can prevent the edges of the filter layer from becoming loose and ensure that air can flow through the filter layer normally.

[0020] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0021] In the present utility model, by providing a conductive woven mesh and a conductive foil made of copper alloy, and connecting the conductive foil to an external ground wire, when static electricity exists in the filter layer, the static electricity will be conducted from the conductive woven mesh to the conductive foil and then to the ground wire through the conductive foil, thereby eliminating the static electricity in the filter layer and preventing the situation where static electricity affects the normal operation of the filter layer.

[0027] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0028] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0029] As Figures 1-4 shown, the present utility model provides an anti-static composite air filtration material, including a filter layer 1, in which a conductive woven mesh 2 is embedded. A plurality of conductive foils 3 are penetrated through both sides of the filter layer 1. The conductive woven mesh 2 is fixedly connected to the conductive foil 3. Both the conductive woven mesh 2 and the conductive foil 3 are made of copper alloy. By setting the conductive woven mesh 2 and the conductive foil 3 made of copper alloy and connecting the conductive foil 3 to an external ground wire, when static electricity exists in the filter layer 1, the static electricity will be conducted from the conductive woven mesh 2 to the conductive foil 3 and then to the ground wire through the conductive foil 3, thereby eliminating the static electricity in the filter layer 1 and preventing the situation where the static electricity affects the normal operation of the filter layer 1. Anti-puncture layers 4 are adhesively bonded to both sides of the filter layer 1. The anti-puncture layer 4 is an aramid fiber woven layer. Since aramid fiber has high strength, the anti-puncture layer 4 made of aramid fiber can prevent the filter layer 1 from being punctured, thereby protecting the filter layer 1. A wear-resistant layer 5 is adhesively bonded to the side of the anti-puncture layer 4 away from the filter layer 1. The wear-resistant layer 5 is a polypropylene layer. By setting the wear-resistant layer 5 made of polypropylene, the filter layer 1 can be protected, thereby extending the service life of the filter layer 1.

[0030] As Figures 1-4As shown, a plurality of ventilation holes 6 are provided on the surface of the wear-resistant layer 5. The ventilation holes 6 can ensure that air can flow through the wear-resistant layer 5 and normally pass through the filter layer 1. A release film 7 is adhered to the side of the wear-resistant layer 5 away from the puncture-resistant layer 4. The release film 7 is a PET film. The release film 7 can shield and protect the wear-resistant layer 5 when the filter layer 1 is not in use. A plurality of easy-tear grooves 8 are provided on the surface of the release film 7. By providing the easy-tear grooves 8 on the surface of the release film 7, the release film 7 can be torn using the easy-tear grooves 8, so as to facilitate the segmentation of the filter layer 1. Edge sealing strips 9 are adhesively bonded to the surfaces of the two wear-resistant layers 5. The puncture-resistant layer 4 and the filter layer 1 are both fixedly connected to the edge sealing strips 9. The conductive foil 3 penetrates through the edge sealing strips 9. The edge sealing strips 9 can prevent the edges of the filter layer 1 from becoming loose and ensure that air can normally flow through the filter layer 1.

[0031] The overall working principle is as follows: By providing the conductive woven mesh 2 and the conductive foil 3 made of copper alloy, and connecting the conductive foil 3 to the external ground wire, when static electricity exists in the filter layer 1, the static electricity will be conducted from the conductive woven mesh 2 to the conductive foil 3, and then conducted to the ground wire through the conductive foil 3, so as to eliminate the static electricity in the filter layer 1 and prevent the situation that the static electricity affects the normal operation of the filter layer 1. Since the aramid fiber has high strength, the puncture-resistant layer 4 made of aramid fiber can prevent the filter layer 1 from being punctured, so as to protect the filter layer 1. By providing the wear-resistant layer 5 made of polypropylene, the filter layer 1 can be protected, thereby extending the service life of the filter layer 1. The ventilation holes 6 can ensure that air can flow through the wear-resistant layer 5 and normally pass through the filter layer 1. The release film 7 can shield and protect the wear-resistant layer 5 when the filter layer 1 is not in use. The edge sealing strips 9 can prevent the edges of the filter layer 1 from becoming loose and ensure that air can normally flow through the filter layer 1. By providing the easy-tear grooves 8 on the surface of the release film 7, the release film 7 can be torn using the easy-tear grooves 8, so as to facilitate the segmentation of the filter layer 1.
