Description

一种耐久的外墙抗裂水泥砂浆
技术领域
本发明涉及一种耐久的外墙抗裂水泥砂浆。
背景技术
水泥是最主要的建筑材料之一，广泛应用于工业民用建筑、道路、水利和国防工程，其主要特性为加入适量水后具有的可塑性，不仅能够在空气中硬化，也能够在水中硬化。现在普通水泥砂浆存在抗张强度低、易龟裂、防水性差、粘结力小、耐药品性不好、不耐磨，不抗裂等本质上的缺限，已经不能满足现在的使用要求。水泥基砂浆、腻子的裂纹、裂缝产生是一个常见的带有普遍性的问题。比如外墙水泥砂浆长期裸露在空气中，往往因湿度的变化膨胀或收缩，湿度变形因水泥砂浆的含水量变化和干缩率有关。外墙水泥砂浆裂缝产生的原因有很多，除在施工、配比、选料、墙体等方面规范、完善外，从水泥砂浆自身可采取有效地防治措施，改善其质量和性质，减少砂浆的干缩裂缝、减少收缩应力，提高砂浆的抗裂性，从而提高外墙的质量。
发明内容
针对现有技术的不足，本发明要解决的问题是，提供一种耐久的外墙抗裂水泥砂浆，具有附着力强、耐老化性能强，提高水泥砂浆的硬度、韧性，增加了抗开裂性能，使用寿命长。
为解决现有技术问题，本发明提供的技术方案是，一种耐久的外墙抗裂水泥砂浆，其由以下重量份数的原料制成：
废橡胶粉3-5份，三丙烯基异三聚氰酸酯2-4份，珍珠岩20-35份，膨润土3-6份，金红石粉末8-14份，海泡石3-7份，硬化剂4-6份，矿渣粉10-15份，普通硅酸盐水泥15-24份，纤维素醚0.04-0.2份，可再分散胶粉6-9份，胶凝材料8-17份，聚合物纤维2-4份，聚乙烯醇4.2-5.6份，苯乙烯一丁二烯一苯乙烯共聚物3.5-5.5份，氧化镁4-6份，硬脂酸钙2.5-3.2份。
本发明的有益效果是：本发明的耐久的外墙抗裂水泥砂浆，具有附着力强、耐老化性能强，提高水泥砂浆的硬度、韧性，增加了抗开裂性能，使用寿命长。
