The invention discloses an environment-friendly composite material for preventing toxic gases, comprising an outer cover layer, an adsorption and degradation layer and a skin-friendly layer arranged in sequence, the outer cover layer is located at the outermost layer; An adsorption-degradable fiber film is deposited on the inner surface of the cloth as an adsorption-degradation layer; the invention also discloses a preparation method of the environmental protection composite material. The invention comprises an outer cover layer, an adsorption and degradation layer and a skin-friendly layer sequentially arranged from outside to inside, and the skin-friendly layer has excellent moisture absorption and air permeability, skin-friendly and antibacterial properties; An adsorption degradation layer is deposited on the surface of the activated carbon layer; in the present invention, each raw material is green, environmentally friendly and easy to degrade, so as to obtain a kind of material that can not only block toxic gases and prevent toxic gases, but also integrate the advantages of physical adsorption and chemical adsorption. , to achieve rapid reduction of toxic gas concentration and continuous and stable decomposition of composite environmental protection materials. |
