Description

一种新型纳米增强再生免烧砖
技术领域
本发明涉及一种新型纳米增强再生免烧砖，具体涉及利用一种利用废弃炉渣、再生骨料制备免烧砖的方法。
背景技术
我国每年有大量的废弃炉渣，主要来源工厂、电厂等，对环境造成了极大的破坏。将废弃炉渣制备成免烧砖可以有效减轻环境的负担，同时也变废为宝、节约自然资源，同时由其制成的免烧砖性能优良保温、隔热。
发明内容
本发明的目的是提供了一种纳米增强免烧砖，工艺简单，对固体废弃物利用率高，所述免烧砖重量轻、强度较好、耐久性好，对能源消耗较小对环境无污染，同时又利用改性的天然植物纤维使其韧性和抗裂性得到明显的加强。
其原料（按重量比计）采用水泥25份、废弃炉渣58份、火山灰11份、可再分散乳胶粉15份、石膏3份、再生骨料15份、植物纤维10份、羟甲基纤维素3份、胶粉0.05份、水22份，上述原料经混合搅拌均匀，再在模具内经振动、挤压成型制成砖坯，蒸汽养护24-48小时后，将其在常温下室外放置12-15天得成品；所述胶粉由以下原料混合而得：纳米碳酸钠5重量份、纳米碳酸钙10重量份、五水偏硅酸钠25重量份；所述植物纤维为秸秆、木质纤维或稻草，上述植物纤维经改性处理，优选利用如下步骤对其进行改性处理，首先将植物纤维粉碎成直径为3-6mm，然后将其置于由（按重量百分比计）5-10%纳米二氧化硅、5-10%纳米碳酸钙、20-30%苯丙乳液、10-15%柠檬酸和35-50%水配制成的溶液中浸渍处理，其中（按重量比计）植物纤维:上述溶液为1:5-10。
本发明的有益技术效果：
本发明工艺简单，对固体废弃物利用率高，所述免烧砖重量轻、强度较好、耐久性好，对能源消耗较小对环境无污染，重量轻、且无污染，产品抗裂性、韧性较好。
具体实施方式
其原料（按重量比计）采用水泥25份、废弃炉渣58份、火山灰11份、可再分散乳胶粉15份、石膏3份、再生骨料15份、植物纤维10份、羟甲基纤维素3份、胶粉0.05份、水22份，上述原料经混合搅拌均匀，再在模具内经振动、挤压成型制成砖坯，蒸汽养护24-48小时后，将其在常温下室外放置12-15天得成品；所述胶粉由以下原料混合而得：纳米碳酸钠5重量份、纳米碳酸钙10重量份、五水偏硅酸钠25重量份；所述植物纤维为秸秆、木质纤维或稻草，上述植物纤维经改性处理，优选利用如下步骤对其进行改性处理，首先将植物纤维粉碎成直径为3-6mm，然后将其置于由（按重量百分比计）5-10%纳米二氧化硅、5-10%纳米碳酸钙、20-30%苯丙乳液、10-15%柠檬酸和35-50%水配制成的溶液中浸渍处理，其中（按重量比计）植物纤维:上述溶液为1:5-10。
