The invention discloses a photocatalyst water-permeable brick surface layer and a preparation method thereof, and belongs to the technical field of road engineering materials. The water-permeable brick is prepared from the following components in parts by mass: 10 to 18 parts of white Portland cement, 70 to 90 parts of aggregate of 20 to 40 meshes, 1.5 to 2.5 parts of waterborne epoxy resin emulsion, 1.5 to 2.5 parts of nano titanium dioxide, 0.5 to 1.5 parts of silica fume and 0.5 to 1.5 parts of a water-permeable brick reinforcing agent. A shell formed by the white Portland cement and the water-borne epoxy resin wraps the surface of the aggregate, and the nano titanium dioxide is dispersed in the water-borne epoxy resin in the shell. The water-borne epoxy resin emulsion is used as a photocatalyst titanium dioxide carrier and is uniformly coated on the surface of the aggregate after being mixed with the white cement, so that the photocatalyst titanium dioxide in the surface layer of the water-permeable brick can be uniformly dispersed, and the maximum light receiving area is achieved.
一种光触媒透水砖面层及其制备方法，属于道路工程材料技术领域。制备原料包括以下质量份的组分：白色硅酸盐水泥10～18份，20～40目的骨料70～90份，水性环氧树脂乳液1.5～2.5份，纳米二氧化钛1.5～2.5份，硅灰0.5～1.5份和透水砖增强剂0.5～1.5份；白色硅酸盐水泥和水性环氧树脂形成的壳体包裹于骨料表面，纳米二氧化钛分散于壳体中的水性环氧树脂中。本发明使用水性环氧树脂乳液作为光触媒二氧化钛载体，与白水泥混合后均匀包裹在骨料表面，保证透水砖面层中的光触媒二氧化钛能够分散均匀，且达到最大受光面积。
