Description

一种保水率高的自清洁透水砖及其制作方法
技术领域
本发明涉及建筑材料技术领域，尤其涉及一种保水率高的自清洁透水砖及其制作方法。
背景技术
随着城市水资源的不断匾乏，以及城市环境人性化的追求，透水砖的研发引起了材料、环境和市政工程专家的广泛关注。透水砖具有良好的渗水性及保湿性，能很好的缓解城市由于被非透水地面铺装覆盖造成的“城市荒漠化”及“热岛效应”，还可以在一定程度上缓解城市内涝，补充城市地下水，调节城市环境，有利于保持城市水平衡。现有的透水砖向高密实、高强度方向发展，其抗压强度比较高，但依然存在诸多缺陷，一方面是透水性非常差，即使有透水性能好的砖块，但其抗压强度达不到路面铺装要求，同时透水砖经过长期使用，表面以及孔隙很容易落入各种污物形成堵塞而不能自动清除，削弱了透水效果，生态效果较差，并且使用中对排水设施的要求较高，如遇到雨后排水不畅的情况发生，则易产生积水问题。另一方面现有的技术生产的透水砖功能较为单一，它们只是简单的使降水透过砖体渗入地下，不能有效去除水中所含污染物，对透过砖体的污水起不到净化作用。为解决这些问题，需要开发一种新型的同时具有透水和净化功能的自清洁透水砖。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种保水率高的自清洁透水砖及其制作方法。
本发明是通过以下技术方案实现的：
一种保水率高的自清洁透水砖，由下列重量份的原料制成：废加气混凝土颗粒30-33、紫砂土25-26、生石灰18-20、水泥7-9、糖滤泥17-19、海泡石绒9-11、硅油4-6、硅酸钠0.7-0.8、石墨烯2.1-2.3、纳米二氧化钛0.4-0.6、三氧化二铑2.2-2.5、硅烷偶联剂KH5805-7、石榴皮6-8、檀香1-2、贯众2-3、适量水。
所述的一种保水率高的自清洁透水砖的制作方法，包括以下步骤：
（1）将石榴皮、檀香、贯众烘干放入炭化炉中于450-500℃的温度下，隔绝空气炭化20-30分钟，冷却至室温加入纳米二氧化钛、硅烷偶联剂KH580、石墨烯研磨40-50分钟；
（2）将糖滤泥水洗后于50-60℃温度下烘干，送入高速混合机中加入硅油、硅酸钠、三氧化二铑和适量的水，以1400-1500转/min的速度高速搅拌15-20分钟，干燥，超声研磨成粉烘干；
（3）将废加气混凝土颗粒、紫砂土于680-730℃高温煅烧处理后粉碎至120-140目，加入步骤（1）、（2）物料及其他剩余成分混匀，投入球磨机中球磨2-3小时，喷水造粒、陈化2天后压制成生砖坯；
（4）将生砖坯自然晾晒风干，在箱式电阻炉中于1060-1100℃烧结1-2小时，自然冷却至室温出料。
本发明的优点是：本发明将石榴皮、檀香、贯众炭化处理后经室温研磨，孔隙表面吸附光催化材料纳米二氧化钛，经光照射时生成羟基自由基、超氧离子自由基以及H2O自由基均具有很强的氧化、分解能力，将各种有机物直接氧化为CO2 和H2O等无机小分子，应用于透水砖中不仅可以降解大气中的汽车尾气等，还具有较强的吸附性，可有效净化污水中的污染物，本发明利用建筑废弃物经资源化处理后生产再生骨料生态透水砖，既推动了建筑废弃物资源化利用工作，提高产品附加值，同时节约大量天然砂石资源，制得的透水砖具有保水率高、强度高、透水性好等优点。
