The invention discloses a stain-resistant wall and floor integrated veneer and a preparation method thereof. The veneer is prepared by smearing a stain-resistant coating on the surface of a prefabricated plate, the stain-resistant coating is subjected to reaction dehydration condensation through amino groups on dopamine molecules and carboxyl groups on graphene oxide, so that the dopamine molecules are fixed on the graphene oxide, bromooctadecane reacts with phenolic hydroxyl groups on the dopamine, the surface of the graphene is grafted with a large amount of long-chain alkyl, the long-chain alkyl also has a good hydrophobic effect, when being illuminated, the stain-resistant coating generates holes h + and electrons e-, the e- reacts with oxygen to produce O2- to attack organic molecules, the holes h + reacts with water to generate -OH, and the two free radicals react together to decompose organic compounds and remove surface stains. and the stain-resistant effect is further achieved.
本发明公开了一种耐污型墙地一体饰面板及其制备方法，该饰面板通过在预制板表面涂抹耐污涂层制得，该耐污涂层通过多巴胺分子上的氨基和氧化石墨烯上的羧基，进行反应脱水缩合，使得多巴胺分子固定在氧化石墨烯上，再将溴代十八烷与多巴胺上的酚羟基进行反应，使得石墨烯表面接枝有大量长链烷基，长链烷基也具有很好的疏水效果，在受到光照时，耐污涂层产生空穴h+和电子e‑，e‑与氧气反应生产O2‑，攻击有机分子，空穴h+与水反应生成‑OH，两种自由基共同反应，从而分解有机化合物，将表面污渍清除，进而达到耐污效果。
