Description
技术领域
本发明属于建筑材料技术领域，具体涉及一种保温材料的制备方法。
背景技术
外墙内保温是建筑保温领域重要的一种保温方式，特别是在既有老建筑中，我国目前存在大量的没有采取墙体保温措施的城镇老建筑，由于节能要求，经常需要进行整栋建筑的外墙外保温改造施工。由于脚手架的搭建和施工安全，业主意见也经常不统一，再加上旧墙面处理等技术障碍，农村大量的民房几乎都没有墙体保温措施。在这些领域，与外保温改造工程相比，内保温改造实施起来更加灵活和有效，可以以户等小单位组织实施内保温改造和施工。
目前内保温系统主要有板系统和砂浆系统。板材系统对墙面的要求较高，如果墙面存在坑洼不平和曲面则需要先进行找平处理，费时费工费材料。板系统对室内的二次装修非常不利，很容易造成破坏，且不易修复，影响美观和保温效果。特别是有机板保温系统还存在火灾隐患。目前使用的砂浆保温系统主要是水泥基的玻化微珠无机保温砂浆，这种砂浆的干密度大，基本在400-600kg/m3之间，导热系数基本在0.080-0.120W/m.K之间，干燥收缩率大，容易引起墙面开裂，并且在空气潮湿的部位极易产生返碱现象，影响美观和保温效果。
发明内容
本发明针对背景技术中存在的问题而提供一种保温材料的制备方法。
为了实现本发明目的而采用的技术方案为：一种保温材料的制备方法，具体制备方法为：1）将原料双氧水，海泡石，石膏，陶瓷废料，粉煤灰，改性添加剂甲基纤维素醚混合，将混合料置于球磨机中进行球磨，使各原料混合均匀，制得发泡水泥浆料；2）将发泡水泥浆料倒入模具中，室温下成型，然后在700～900℃高温下烧制1～3小时，自然降温，切割成制品。
作为本发明的另一种优选，所述原料按质量份数计，质量分数为10～50%的双氧水30-50份，海泡石20～30份，石膏5-10份，陶瓷废料15～25份，粉煤灰15～25份，改性添加剂2～6份。
作为本发明的另一种优选，所述的改性添加剂，按质量百分含量计，包括甲基纤维素醚40～60%、无机盐类化合物20～40%，硬脂酸钙10～30%、乳胶粉5～10%。
其中，所述的改性添加剂由以下方法制得：将甲基纤维素醚加入到硬脂酸钙和无机盐类化合物的混合物中，球磨1～3小时；继续加入乳胶粉，球磨0.5～2小时。
所述的无机盐类化合物为硫酸镁、硫酸钠或碳酸铵中的一种。
本发明相对于现有技术，具有以下技术优点：
1）本发明的配方中选用了陶瓷废料、粉煤灰等工业废料，既降低了生产成本，同时又缓解了陶瓷废料、粉煤灰堆存处理带来的环境污染问题。
2）本发明选用的陶瓷废料、粉煤灰可改善保温材料的保温性能，具有抗风化，耐腐蚀，抗冻融等特点。
3）本发明选用的改性添加剂不仅具有稳泡的作用，还具有促进水泥与陶瓷废料和粉煤灰快速凝结、硬化的功效。
