防水卷材用油的使用效果影响因素

截止2011年底，我国现有城乡建筑面积约450多亿平米“十二五”期间，每年   新建建筑将达到40~50亿平方米，同时既有住房每年约有近10%建筑需要各方面维修。其中屋面、墙体、卫生间、地下室等防水失效、渗漏约占一半以上，己成为房地产投诉的   大热点，引发的各类质量和民事事件不断攀升。渗漏的主要原因是：产品质量以次充好，伪冒假劣，不符合产品标准要求；施工过程不按工艺要求，野蛮施工；施工质量验收过程中开发商、监理、施工单位、检验机构弄虚作假；缺少系统的现场检测方法和检测设备，无法现场检测评定。调研发现，目前我国屋面防水约有70%以上为沥青类防水卷材，新建建筑特别是既有建筑屋面改造维修，仅仅过了几年就开始漏水，而且多数渗漏点出现在卷材与卷材搭接处，出现搭接面积、剥离强度不够等普遍情况。
