Embodiment 1

[0018] As shown in FIG. 1 , the filter material 10 of carbon-inserted non-woven fabric includes an upper layer of non-woven fabric 10a, a middle layer of reticular non-woven fabric 10b, activated carbon particles 10c and a lower layer of non-woven fabric 10d.

[0019] The manufacturing process of the carbon sandwich non-woven filter material is as follows: as shown in Figure 1, the lower non-woven fabric 1, the first layer of hot-melt adhesive film 2, and the middle layer of mesh non-woven fabric 3 are unrolled by the unwinder, and Press, middle, and top are stacked in sequence, and then the activated carbon particles 4 are sprinkled on it with a granulator 5, and then the second layer of hot melt adhesive film 6 and the lower layer of non-woven fabric 7 are sequentially stacked on it, Then, it is composited by the ultrasonic composite machine 8, and then thermally composited by the thermal composite machine 9. The surface temperature of the hot roller is controlled at 150°C-18...

Embodiment 2

[0021] As shown in FIG. 1 , the filter material 10 of carbon-inserted non-woven fabric includes an upper layer of non-woven fabric 10a, a middle layer of reticular non-woven fabric 10b, activated carbon particles 10c and a lower layer of non-woven fabric 10d.

[0022] The manufacturing process of carbon sandwich non-woven filter material is shown in Figure 1. The lower layer of non-woven fabric 1, the first layer of hot-melt adhesive film 2, and the middle layer of mesh non-woven fabric 3 are unrolled through the unwinder, and sequentially pressed Lay up in the order of lower, middle and upper, and then use the granulator 5 to spread the activated carbon particles 4 on it, and then lay the second layer of hot melt adhesive film 6 and the lower layer of non-woven fabric 7 sequentially on it, and then, Composite finished product 10 is made by ultrasonic composite machine 8, and it is wound up.

Embodiment 3

[0024] As shown in Fig. 1, the filter material 10 of interlaced charcoal non-woven fabric comprises an upper layer of non-woven fabric 10a, a middle layer of reticular non-woven fabric 10b, activated carbon particles 10c and a lower layer of non-woven fabric 10d.

[0025] The manufacturing process of carbon sandwich non-woven filter material is shown in Figure 1. The lower layer of non-woven fabric 1, the first layer of hot-melt adhesive film 2, and the middle layer of mesh non-woven fabric 3 are unrolled through the unwinder, and sequentially pressed Lay up in the order of lower, middle and upper, and then use the granulator 5 to spread the activated carbon particles 4 on it, and then lay the second layer of hot melt adhesive film 6 and the lower layer of non-woven fabric 7 sequentially on it, and then, Carry out thermal lamination with heat laminating machine 9 again, and the surface temperature of hot roller is controlled at 160 ℃-180 ℃ to make finished product 10, and it is...

Abstract

The invention discloses a carbon folded non-woven filter materials and its manufacturing technology, the filter materials comprising of the upper,middle,low non-woven layers and active carbon placed in the middle of non-woven network, its manufacturing processes are : (1) low non-woven volumes, the first hot melt gum membrane or hot melt gum network or low melting point non-woven volumes the middle layer non-woven network volumes, or compound non-woven fabrics (network non-woven face up) volumes, (2) spreading active carbon (3) the second hot melt gum membrane or hot melt gum network or low melting point non-woven volumes ,upper layer non-woven volumes (4) ultrasonic compounded or hot pressing compounded, (5) rolling. The active carbon grain are fixed between upper-low non-woven through the middle layer non-woven network, its active carbon is not directly contact or hardly contact with the adhesive, it guarantees the active carbon and its composite materials perform at the maximal limitation. The manufacturing process is simple, efficient, of low production cost, it also save energy and protect the environment.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a filter material of carbon intercalated non-woven fabric and a manufacturing process thereof. Background technique [0002] Activated carbon is a kind of carbon-containing material such as plants or coal, which is prepared by carbonization and activation. It has a rich pore structure and a large specific surface area. It has excellent adsorption properties (both physical and chemical adsorption properties), non-toxic, tasteless, and stable chemical properties. carbon materials. Because it can effectively remove harmful substances such as benzene, ammonia, formaldehyde, odor, and peculiar smell in the air, and has effective antibacterial effects, it is widely used in air purification and other fields. There are also many air purification products made of it, such as activated carbon fiber, activated carbon non-woven fabric, activated carbon foam, activate...
