Description
技术领域
本发明涉及加气砖技术领域，具体涉及一种耐油加气砖及其制作方法。
背景技术
近年来，随着工业化进程的加快和城市化水平的提高，也带来了各种环境压力和问题，工业生产过程产生的各种固废以及城市建设拆迁重造带来的固废等一直困扰着居民的生活环境，本发明将固废作为原材料添加到加气砖中，实现了废物的循环利用，减少了对环境的污染，符合可持续发展战略要求。
加气砖是通过高温蒸压设备工艺生产的加气混凝土砌块。加气混凝土砌块以水泥、矿渣、砂、石灰等为主要原料，加入发气剂，经搅拌成型、蒸压养护而成的实心砌块，加气混凝土按用途，可分为非承重砌块、承重砌块、保温块、墙板与屋面板五种。
传统实心粘土砖重量大，不仅浪费国家粘土资源、价格高外，而且也无法满足一些特殊建筑用砖的要求，因此现在许多先进地区已经全面禁止红砖使用，取而代之大力提倡加气砖。和传统的粘土砖和普通混凝土砖相比，加气砖不仅重量轻，还具有保温隔热、隔音性能优、抗震能力强、加工性能好、耐高温性能佳、适应性强等优点。但是，目前我国有关加气砖的生产技术还不够成熟，使得加气砖发展技术缓慢，还无法满足多元化市场的需求。
发明内容
本发明的目的就是提供一种耐油加气砖及其制作方法，以克服现有技术的不足。
本发明的目的是这样实现的：
一种耐油加气砖，其特征在于，由下列重量份的原料制成：水泥8-12、生石灰10-15、脱硫石膏13-15、氧化铬5-7、铝粉0.5-0.8、葡萄碳酸钠5-7、甲醛纤维素3-6、膨胀蛭石10-12、花生油油酸3-5、刺槐豆胶2-5、松香0.6-1、聚乙烯醇4-7、辣椒籽0.3-0.5、八角0.7-0.8、助剂3-6、适量水；所述的助剂由下列重量份原料制成：聚苯醚0.03-0.05、碳纳米管0.1-0.4、聚氧乙烯醚0.02-0.04、硅酸钠0.2-0.5、三乙胺1.4-2.7、硅灰石粉1-3、乌洛托品0.01-0.02、樟脑0.1-0.3、柏木油1-3、花生壳2-4、三氯乙基磷酸酯1.2-2.3，其制备方法是将各物料粉碎混合，加热至70-80℃，搅拌反应30-40分钟，即得。
所述的一种耐油加气砖的制备方法，其特征在于包括以下步骤：
（1）将香辣椒籽、八角一起在水中煎煮2-3小时过滤，所得滤液真空浓缩提取，得中药提取物；
（2）将步骤（1）的滤渣和脱硫石膏、氧化铬、膨胀蛭石混匀后，于700-800℃下煅烧3-4小时，冷却，研磨，加入花生油油酸、刺槐豆胶、松香、聚乙烯醇搅拌均匀；
（3）将步骤（1）、（2）反应物料以及其它剩余成分，投入搅拌机里搅拌混合8-10分钟，得混合料浆；
（4）将所得混合料浆浇筑入模成型，于44-53℃下预养1-3 小时，脱模，切割，得砌块坯；再将砌块坯放入反应釜中蒸压养护12-15 小时，入库即得。
本发明有以下有益效果：采用本发明生产工艺制得的加气砖容重轻，且具有耐油性，和普通加气砖相比，本发明制得的加气砖的耐油性能和抗渗性能均有所提高，同时通过优化配方，添加中药成分，不仅能抗菌还能提高加气砖的孔隙率，具有较好的市场价值，值得推广使用。
具体实施方式
