    外墙保温系统对建筑饰面涂层的高要求

    发布时间:2017-07-04  浏览:1190次  字号:  

     近年来,外墙外保温技术在国内不同地区得到了大力推广和应用,在现行的行业标准JGJ144-2004《外墙外保温技术规程》中规定了五种外墙外保温体系,其中应用较多的是膨胀聚苯板薄抹灰外墙外保温系统,该系统的外饰面层明确规定需要采用涂料饰面。在实际操作中,有相当一部分外墙外保温工程与涂料装饰工程分别是由不同的厂家施工,但并非所有的保温施工企业对涂料的应用都很熟悉,因此,在保温涂层施工完后没有给建设方及时提出饰面涂层应具有的性能要求;加上部分涂料生产施工企业对保温基层的特征没有充分了解,仍按照传统的材料和施工方式在保温基层上施工,最后导致外保温工程涂层饰面出现开裂、空鼓、剥落等现象,在责任面前建设双方又相互推诿扯皮,带来很大的麻烦。

    1、腻子柔韧性要高。腻子施工后固化干燥形成的腻子层,其柔韧性应大于保温体系抗裂砂浆的柔韧性,即保温体系基层上施工必须采用柔性适当的腻子才能保证腻子层不因基层变形而开裂。根据经验,对于薄抹抗裂砂浆(小于5mm)测试其柔韧性的直观方法可以采用弯曲样板法。  
    试件的制备及测试过程描述如下:首先取一块150×400×20mm的EPS板(18-20㎏/m?),把配好的抗裂砂浆抹涂在EPS板上,约2-3mm厚,然后把事先裁好的玻纤网格布用抹子压入抗裂砂浆中刮平,把样板在常温下养护3天后即可测试。测试时双手各把一端缓慢弯曲(抗裂层背面方向),当测试样板的两端基本达到平行时,观察抗裂层有无裂纹出现。对于柔性较好的抗裂砂浆,其变形量在上述测试中一般不出现裂纹,实际工程应用中保温基层出现大面积开裂的机会也较低。
