Fluorescent photocatalytic water-permeable brick and preparation method thereof
The invention belongs to the technical field of engineering construction materials, and particularly relates to a fluorescent photocatalytic water-permeable brick and a preparation method thereof. Thefluorescent photocatalytic water-permeable brick is of a double-layer structure, wherein the lower layer of the water-permeable brick is a recycled aggregate water-permeable layer, and the upper layer of the water-permeable brick is a fluorescent photocatalytic composite concrete layer. According to the invention, the water-permeable brick is used as a matrix and is divided into a double-layer structure by adopting a layered forming method, so the strength of the water-permeable brick is guaranteed, and the utilization rate of a fluorescent material and a carbon nitride nanosheet is increased; the wear resistance and the waterproof performance of the water-permeable brick are enhanced by adding quartz sand and a PTB emulsion; and due to the addition of the carbon nitride nanosheet and fluorescent powder, the water-permeable brick has the functions of self-sustained luminescence, visible-light catalytic gas purification and self-cleaning. The water-permeable brick is suitable for parkaisles or sidewalks, meets the permeable requirements of pavements, has the fluorescent property to play a role in identification at night, continuously degrades pollutants through photocatalysis, keeps clean and tidy, and is beneficial to popularization and application.
本发明属于工程建筑材料技术领域，具体涉及一种荧光光催化透水砖及其制备方法。所述的一种荧光光催化透水砖分为双层结构，透水砖下层为再生骨料透水层，上层为荧光光催化复合混凝土层。本发明利用透水砖为基体，采用分层成型方法，将透水砖分成双层结构，即保证了透水砖的强度，又提高了荧光材料与氮化碳纳米片的利用率，并且加入了石英砂及PTB乳液，增强了透水砖的耐磨性能和防水性能；其次由于氮化碳纳米片和荧光粉的加入，使得该透水砖具备了自行持续发光，可见光催化净气，自清洁。本发明适用公园走道或人行道，不仅满足路面透水要求，并且具备的荧光性能在夜晚发光起到辨识作用，并持续光催化降解污染物，保持干净整洁，利于推广应用。
