Wall cloth for purifying formaldehyde and preparation method thereof
The invention discloses wall cloth for purifying formaldehyde and a preparation method of the wall cloth, and relates to the field of home decoration. The prepared wall cloth for purifying formaldehyde comprises the composite nanofiber membrane and the phosphorus-nitrogen flame-retardant fiber fabric, thiourea, titanium carbide and triphenylphosphine are calcined to obtain modified carbon nitride, and the photocatalytic performance is improved; by introducing triphenylphosphine, the crystal structure of carbon nitride is reserved, and the photocatalytic performance of carbon nitride is improved through the synergistic effect of triphenylphosphine and titanium dioxide quantum dots; under the excitation of visible light, carbon-hydrogen bonds in formaldehyde are oxidized, and formaldehyde is decomposed into harmless substances; the preparation method comprises the following steps: carrying out addition on amino of trihydroxymethyl aminomethane and a carbon-nitrogen triple bond of dicyandiamide to generate a biguanide structure, adding phosphorus pentoxide for esterification, adding urea, and carrying out acid-base neutralization to prepare a phosphorus-nitrogen flame retardant; the flame retardant is decomposed into phosphoric acid at high temperature, so that the speed of dehydrating and charring on the surface of the fiber can be increased, a compact carbon layer is quickly generated, and a fire source and combustible materials are isolated.
本发明公开了一种净化甲醛的墙布及其制备方法，涉及家居装修领域。本发明制备的净化甲醛的墙布，包括复合纳米纤维膜和磷氮阻燃纤维面料，硫脲、碳化钛和三苯基膦煅烧得改性氮化碳，提高光催化性能；三苯基膦的引入保留了氮化碳的晶体结构，与二氧化钛量子点协同作用改善了氮化碳的光催化性能；在可见光激发下，氧化甲醛中的碳氢键，将甲醛分解为无害物质；三羟甲基氨基甲烷的氨基和双氰胺的碳氮三键加成生成双胍结构，加入五氧化二磷酯化，加入尿素，通过酸碱中和制备磷氮系阻燃剂；阻燃剂在高温下分解成磷酸，能加快纤维表面脱水成炭的速度，迅速生成致密炭层，隔离火源和可燃物。
