Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

With reference to fig. 1, the present invention discloses an embodiment of a composite carbon cloth, which includes a supporting layer 10, a first adhesive layer 20, a carbon adsorption layer 30, a second adhesive layer 40 and a melt-blown filter layer 50 stacked in sequence.

The first adhesive layer 20 is used for adhering the carbon adsorption layer 30 to the support layer 10, the second adhesive layer 40 is used for adhering the carbon adsorption layer 30 to the melt-blown filter layer 50, and both the first adhesive layer 20 and the second adhesive layer 40 are polyurethane adhesive layers.

The composite carbon cloth comprises the carbon adsorption layer 30 and the melt-blown filter layer 50 which are stacked, the carbon adsorption layer 30 enables the composite carbon cloth to have a good adsorption function, and the melt-blown filter layer 50 enables the composite carbon cloth to have a good filtering function, so that the composite carbon cloth has the good adsorption function and the good filtering function.

In addition, the carbon adsorption layer 30 is adhered to the support layer 10 and the melt-blown filter layer 50 respectively by the polyurethane adhesive layer, and the polyurethane adhesive layer reacts with moisture in the air to form a product with stable property and cannot be melted along with the rise of temperature.

And PU glue is often adopted in the traditional composite cloth at present for bonding, and the PU glue can be melted along with the rise of temperature, thereby easily causing the instability of the composite cloth.

In this embodiment, the carbon adsorption layer 30 is a coconut shell activated carbon adsorption layer. The coconut shell activated carbon has the advantages of developed pores, large adsorption capacity, good effects of decoloring and adsorbing organic matters, quick deodorization, high product strength and long service life, and is widely applied to the industries of food, power plants, mines, metallurgy, petrifaction, steel making, fine chemical engineering and the like.

In other embodiments, the carbon adsorption layer 30 may be a coal-based activated carbon adsorption layer.

In the present embodiment, the ratio of the mass of the carbon adsorption layer 30 to the sum of the masses of the first adhesive layer 20 and the second adhesive layer 40 is 100: 20 to 40.

By controlling the amount of the polyurethane adhesive layer (the first adhesive layer 20 and the second adhesive layer 40), on one hand, the carbon adsorption layer 30 can be stably adhered to the support layer 10 and the melt-blown filter layer 50, and on the other hand, the adsorption function of the composite carbon cloth product is prevented from being influenced.

More preferably, the ratio of the mass of the carbon adsorption layer 30 to the sum of the masses of the first adhesive layer 20 and the second adhesive layer 40 is 100: 25.

In the present embodiment, the support layer 10 is a porous nonwoven fabric, and the thickness of the porous nonwoven fabric is 0.2mm to 1 mm. The porous non-woven fabric can play a better supporting role, and the porous non-woven fabric does not influence the flow of air and cause the reduction of the air purification efficiency, so that the porous non-woven fabric is a better choice for the supporting layer 10.

Preferably, the gram weight of the composite carbon cloth is 90g/m²～900g/m². The proper gram weight can ensure the adsorption function of the composite carbon cloth product.

More preferably, the gram weight of the composite carbon cloth is 200g/m²。
