Cement-based photocatalytic material, preparation method and self-cleaning outer wall decorative plate based on material
The invention discloses a cement-based photocatalytic material, a preparation method and a self-cleaning exterior wall decoration plate based on the material, the photocatalytic material comprises Portland cement and a photocatalytic dispersion liquid, and the photocatalytic dispersion liquid comprises a surfactant, a nano metal oxide, a modifier and deionized water in parts by weight; the preparation method comprises the following steps: firstly, mixing a part of the surfactant, the nano metal oxide and deionized water to prepare a dispersion liquid A, and then mixing the modifier with the rest of the surfactant to prepare a dispersion liquid B; dropwise adding the dispersion liquid of the group B into the dispersion liquid of the group A to prepare a photocatalytic dispersion liquid; and uniformly mixing Portland cement with the photocatalytic dispersion liquid to prepare the cement-based photocatalytic material. The cement-based photocatalytic slurry can form a super-flat cement-based photocatalytic layer on the surface layer of a self-cleaning outer wall decorative plate, and the surface of the cement-based photocatalytic slurry is free of pores, so that the cement-based photocatalytic slurry has good attractiveness and strong hydrophobicity.
本发明公开了一种水泥基光催化材料、制备方法及基于该材料的自洁净外墙装饰板材，光催化材料包括硅酸盐水泥及光催化分散液，光催化分散液按重量份数计包括表面活性剂、纳米金属氧化物、改性剂及去离子水；制备时先将部分的表面活性剂、纳米金属氧化物与去离子水混合制得A组分散液再将改性剂与剩余的表面活性剂混合制得B组分散液，随后将B组分散液滴加至A组分散液中制得光催化分散液最后将硅酸盐水泥与光催化分散液混匀制得该水泥基光催化材料。该水泥基光催化浆液能够在自洁净外墙装饰板材的表层形成超平的水泥基光催化层，且表面无孔隙，具有良好的美观度，疏水性强。
