Formaldehyde degradation functional gelling building material with sandwich structure and preparation method of formaldehyde degradation functional gelling building material
The invention aims to provide a formaldehyde degradation functional alkali-activated cementing material with a sandwich structure, the formaldehyde degradation functional alkali-activated cementing material is composed of a middle layer and surface layers covering the upper surface and the lower surface of the middle layer, and the middle layer and the surface layers comprise the following raw materials: 40-60 parts by mass of blast furnace slag, 10-20 parts by mass of low-calcium fly ash, 10-20 parts by mass of alkaline magnesium slag and 10-15 parts by mass of an alkali activator; the surface layer further comprises 2-7 parts by mass of a functional catalyst; the functional catalyst is a gelatinous micro-nano TiO2 (titanium dioxide) particle. The formaldehyde degradation functional gelling building material with the sandwich structure comprises an alkali-activated gelling material intermediate composed of C-A-S-H gel and a three-dimensional network zeolite structure, and a TiO2 photocatalyst layered outer layer loaded with a hydrophobic gel state. The indoor living environment is improved, the application field of the photocatalyst is widened, and the high-added-value application of the solid-waste-based alkali-activated cementing material is realized.
本发明旨在提供一种三明治结构甲醛降解功能性碱激发胶凝材料，由中间层和中间层上下表面覆盖的表面层组成，中间层和表面层包括以下原料：40～60质量份高炉矿渣、10～20质量份低钙粉煤灰、10～20质量份碱性镁渣、10～15质量份碱激发剂；所述表面层还包括2～7质量份功能性催化剂；所述功能性催化剂是凝胶状的微纳米TiO2颗粒。所述三明治结构甲醛降解功能性胶凝建筑材料有C‑A‑S‑H凝胶和三维网状类沸石结构构成的碱激发胶凝材料中间体，以及负载疏水凝胶态的TiO2光催化剂层状外层。改善室内居住环境，拓宽光催化剂的应用领域，实现固废基碱激发胶凝材料的高附加值应用。
