Problems solved by technology

The existing activated carbon cloth adopts the method of hot rolling to thermally compound the activated carbon particles or powder and the hot-melt rubber powder into various cloths. The activated carbon powder in the carbon cloth made by this method is not easy to distribute evenly in the cloth. , the production requires high equipment and is easy to pollute the environment. It is easy to drop powder particles during use. In addition, it does not have a flame-retardant effect; another fiber cloth with activated carbon is synthesized by melting resin slices and activated carbon powder. It is made by spinning, the production process of this kind of activated carbon fiber cloth is cumbersome, the manufacturing cost is high, and the carbon powder is covered by plastic resin, which greatly affects the function of the activated carbon cloth. In addition, the high content of carbon powder will affect the activated carbon cloth. It has high strength and does not have flame retardant properties; there is also a kind of activated carbon powder mixed with adhesive to prepare carbon paste for coating, which is directly coated on the cloth and then dried to form activated carbon cloth. Activated carbon made by this process Cloth often has good bonding fastness between activated carbon powder and cloth surface due to high adhesive content, but the film-forming characteristics of conventional adhesives will weaken the adsorption capacity of activated carbon. Affected, one-time coating will lead to insufficient amount of carbon powder, and activated carbon powder is easy to fall off and crack after multi-layer coating and drying, which will affect the specific application of the product

Abstract

The invention relates to a flame-retardant activated carbon fabric and a preparation method thereof. The flame-retardant activated carbon fabric is characterized in that an activated carbon layer, a water-based adhesive film layer and a hot-melt adhesive powder particle layer are sequentially covered on a base material which is subjected to flame-retardant treatment. The preparation method comprises the following steps of: spraying or padding the base material with an environment-friendly water-based flame retardant and drying; serially coating a prepared activated carbon paste and a water-based flame-retardant hot-melt adhesive powder particle paste on the base material, and drying to obtain the final product of flame-retardant activated carbon fabric. During the drying process, the water-based adhesive film layer is formed between the carbon layer and the hot-melt adhesive powder particle layer. The preparation method of the flame-retardant activated carbon fabric is simple and environment-friendly, and the product has good flame retardant property. Owing to the good adsorption property of activated carbon, the fabric can remove formaldehyde, benzene, TVOC and other harmful gases in the air. When the fabric is used, the fabric can be cut freely and laminated thermally. The flame-retardant activated carbon fabric is easy and convenient to use and has a wide application range.
