Problems solved by technology

[0002] Activated carbon fiber is a good adsorption material, which can absorb and recycle waste gas of benzene, ketone, ester and petroleum, and has a fast adsorption speed and a large adsorption capacity. It can be widely used in the fields of water purification and air purification. But at present, it is only used in industrial environmental protection, and it is almost blank in civilian applications. The main reason is that activated carbon fibers are first carbonized and then activated at high temperature. Secondary processing and molding, and there is no way to use the production line for mass production, resulting in almost blank civilian products on the market

Embodiment 1

[0014] The present embodiment 1 provides a kind of dry-process modified activated carbon fiber GACF composite material, comprising: 50%-65% by weight of activated carbon fiber, 25%-35% by weight of the shaping carrier and 10%-20% by weight of adhesive.

[0015] The shaping carrier adopts long fibers; and the binder adopts superfine rubber powder.

[0016] Specifically, the long fibers are, for example but not limited to, polyester filaments; the ultrafine rubber powder is ultrafine hot melt adhesive powder.

[0017] Specifically, the dry-process modified activated carbon fiber GACF composite material of the present embodiment uses long fibers as the shaping carrier of the dry-process modified activated carbon fiber GACF composite material. After the ultrafine rubber powder binds the activated carbon fiber and the long fiber together , the long fiber can not only play a role in shaping the activated carbon fiber, but also make the activated carbon fiber have a better tensile f...

Embodiment 2

[0022] On the basis of Example 1, this Example 2 provides a method for preparing a dry-process modified activated carbon fiber GACF composite material, including: step S1, mixing the required raw materials; step S2, mixing the mixture in step S1 Carry out carding and spreading, and then put it into a high-temperature environment to fully dissolve the mixture, and then perform cold rolling and shaping to obtain a felt-like semi-finished product; and step S3, cutting the felt-like semi-finished product to obtain a finished product with a preset width .

[0023] Specifically, in step S2, a mat-like semi-finished product with uniform thickness is ensured to be formed by cold rolling and shaping.

[0024] In the step S1, the required raw materials include: 50%-65% by weight of activated carbon fiber, 25%-35% by weight of a shaping carrier and 10%-20% by weight of a binder.

[0025] The shaping carrier adopts long fibers; and the binder adopts superfine rubber powder.

[0026] Spe...

Abstract

The invention relates to a dry-modified activated carbon fiber GACF composite and a preparation method thereof. The dry-modified activated carbon fiber GACF composite is prepared from the raw materials in percentage by weight: 50%-65% of activated carbon fibers, 25%-35% of a shaping carrier and 10%-20% of a bonding agent. According to the dry-modified activated carbon fiber GACF composite, continuous fibers serve as the shaping carrier of the dry-modified activated carbon fiber GACF composite, and after the activated carbon fibers and the continuous fibers are bonded together through superfinerubber powder, the continuous fibers can shape the activated carbon fibers and further enable the activated carbon fibers to have good drawing force; and the superfine rubber powder is adopted as thebonding agent, thus the activated carbon fibers and the continuous fibers can be bonded three-dimensionally, it can be guaranteed that ventilation cavities in the formed dry-modified activated carbonfiber GACF composite are similar to sponge air cavities, it is guaranteed that the activated carbon fibers still keep good adsorption performance, and thus the dry-modified activated carbon fiber GACF composite can be applied to civil processing.

Description

technical field [0001] The invention relates to the technical field of activated carbon fiber material composites, in particular to a dry-process modified activated carbon fiber GACF composite material and a preparation method thereof. Background technique [0002] Activated carbon fiber is a good adsorption material, which can absorb and recycle waste gas of benzene, ketone, ester and petroleum, and has a fast adsorption speed and a large adsorption capacity. It can be widely used in the fields of water purification and air purification. But at present, it is only used in industrial environmental protection, and it is almost blank in civilian applications. The main reason is that activated carbon fibers are first carbonized and then activated at high temperature. Secondary processing and molding, and there is no way to use the production line for mass production, resulting in almost blank civilian products on the market. [0003] The invention mainly solves the problem of ...
