The invention relates to the technical field of green building materials, particularly to a titanium dioxide-based self-cleaning building material, which is prepared from the following components in parts by mass: 20-30 parts of cement, 20-40 parts of aggregate, 4-8 parts of glass sand, 6-12 parts of glass fiber, 8-12 parts of expanded vermiculite, 0.8-1.6 parts of titanium dioxide, 2-9 parts of fly ash, 1.2-3.6 parts of a dispersing agent, 0.8-2.4 parts of a defoaming agent and 0.1-0.6 part of a nano modifier. According to the titanium dioxide self-cleaning type building material, the cement,the aggregate, the glass sand, the glass fibers, the expanded vermiculite, the fly ash, the dispersing agent and the defoaming agent are mixed to obtain the concrete base layer, and the concrete baselayer is coated with the titanium dioxide coating to obtain the self-cleaning type building material, so that raw materials are simple and easy to obtain, formaldehyde is not contained, the self-cleaning type building material is more environmentally friendly, self-cleaning can be achieved in the using process, the service life is long, and yellowing is not likely to happen.
本发明涉及绿色建筑材料技术领域，尤其是一种基于二氧化钛的自洁型建筑材料，其质量份组成如下：水泥20‑30份、骨料20‑40份、玻璃砂4‑8份、玻璃纤维6‑12份、膨胀蛭石8‑12份、二氧化钛0.8‑1.6份、粉煤灰2‑9份、分散剂1.2‑3.6份、消泡剂0.8‑2.4份、纳米改性剂0.1‑0.6份；本发明中的二氧化钛自洁型建筑材料，水泥、骨料、玻璃砂、玻璃纤维、膨胀蛭石、粉煤灰、分散剂、和消泡剂混合得到混凝土基层，在混凝土基层外涂覆一层二氧化钛涂层得到自洁型建筑材料，原料简单易得，不含甲醛，绿色更环保，而且使用过程中可以自洁，使用寿命长，不易泛黄。
