Description

抗裂砂浆
技术领域
本发明涉及用于涂抹外墙上用于保护保温砂浆层的抗裂砂浆。
背景技术
人类的现代文明依赖于能源、信息和材料三大支柱。能源被当前世界各国普遍重视，是人类面临的四大生存问题之一。而随着工业文明的快速发展，地球上可被人类利用的石油、煤炭等资源币在日渐枯蝎，对于人类而言能源危机总的趋势不可避免。由于受科学技术发展水平的制约，人类开发能够从根本上解决能源危机的新能源尚需时日，所以如何高效的节能、降低能耗就成为了当前解决问题的关键。70年代发生的世界性能源危机，引起了各国政府对本国的能源利用情况的高度重视，通过较为全面的分析调查，发现建筑能耗在社会总能耗中所占比例较大，因此，各国在建筑设计和施工、新型建筑保温材料的开发和应用、建筑节能法规的制定和实施等方面做了大量的工作，在取得可观的经济效益的同时还改善了人类赖以生存的自然环境。通常在墙体上设置保温砂浆层，但是保温砂浆暴露在空间中容易吸水裂开，这就需要在保温砂浆层上设置抗裂砂浆，但是现有的抗裂砂浆效果较差。
发明内容
本发明所要解决的技术问题在于提供抗裂砂浆，强度好，导热系数低，抗裂效果好。
为解决上述现有的技术问题，本发明采用如下方案：抗裂砂浆，其特征在于：包含以下成分且各成分的质量百分比为：
水泥              20～35％
石英砂            60～80％
可再分散乳胶粉    1～4％
纤维素醚          0.3～0.9％
防水剂            1～2％。
作为优选，包含以下成分且各成分的质量百分比为：
水泥              20％
石英砂            75％
可再分散乳胶粉    3％
纤维素醚          0.3％
防水剂            1.7％。
作为优选，包含以下成分且各成分的质量百分比为：
水泥              30％
石英砂            65％
可再分散乳胶粉    2.4％
纤维素醚          0.6％
防水剂            2％。
作为优选，包含以下成分且各成分的质量百分比为：
水泥              35％
石英砂            60％
可再分散乳胶粉    3.1％
纤维素醚          0.9％
防水剂            1％。
作为优选，所述水泥为42.5级普通硅酸盐水泥。
作为优选，所述所述可再分散乳胶粉为乙烯-醋酸乙烯共聚型高分子聚合物，最低成膜的温度为0℃。
作为优选，所述纤维素醚采用羟丙基甲基纤维素醚。
作为优选，所述防水剂是由粘土矿物为载体，添加液体有机硅制成。
有益效果：
本发明采用上述技术方案提供抗裂砂浆，强度好，导热系数低，抗裂效果好，能够很好得保护保温砂浆层。
具体实施方式
实施例一：
抗裂砂浆，包含以下成分且各成分的质量百分比为：
水泥              20％
石英砂            75％
可再分散乳胶粉    3％
纤维素醚          0.3％
防水剂            1.7％。
所述水泥为42.5级普通硅酸盐水泥。所述所述可再分散乳胶粉为乙烯-醋酸乙烯共聚型高分子聚合物，最低成膜的温度为0℃。所述纤维素醚采用羟丙基甲基纤维素醚。所述防水剂是由粘土矿物为载体，添加液体有机硅制成。抗裂砂浆，强度好，导热系数低，抗裂效果好，能够很好得保护保温砂浆层。
实施例二：
抗裂砂浆，包含以下成分且各成分的质量百分比为：
水泥              30％
石英砂            65％
可再分散乳胶粉    2.4％
纤维素醚          0.6％
防水剂            2％。
与实施例一相比较，纤维素醚用量增加，成本增加，但是强度更好，导热系数更低，粘结拉伸性能更好。
实施例三：
抗裂砂浆，包含以下成分且各成分的质量百分比为：
水泥              35％
石英砂            60％
可再分散乳胶粉    3.1％
纤维素醚          0.9％
防水剂            1％。
与实施例二相比较，纤维素醚用量继续增加，成本增加，但是黏性过大，对施工性能有一定的影响。
