Product description

产品说明

本产品是一种以丁基橡胶、高分子量聚异丁烯及增粘剂等配制成的自粘橡胶为基料,强韧的高密度聚乙烯膜或铝箔作为上表面材料,可剥离的涂硅隔离膜或涂硅隔离纸为下表面防粘隔离材料制成的防水材料。具有低温柔性、自愈性、及粘结性能好的特点,可常温施工、施工速度快、符合环保要求。

产品特点

  ※ 不用粘结剂,也不须加热烤至熔化,只须撕去隔离层,即可牢固地粘结在基层上。施工方便且施工速度极快。
   ※ 具有丁基橡胶优异的弹性,延伸率极佳,很好地适应基层的变形和开裂;
   ※ 具有优异的对基层的粘接力,粘结力往往大于其剪切力(粘合面外断裂),确保搭接严密可靠;
   ※ 极具特色的“自愈功能”,能自行愈合较小的穿刺破损,在遭遇穿刺或硬物嵌入时,会自动与这些物体合为一体,保持良好的防水性能;
    ※ 施工安全,不污染环境,施工简便干净,容易做到现场文明施工;
    ※ 耐腐蚀:该卷材具有很好的耐酸、耐碱,耐化学腐蚀,在各种环境中具有优良的耐老化性能;    ※ 适用于工业与民用建筑的屋面、地下室、室内、市政工程和蓄水池、游泳池以及地铁隧道防水。还适用于木结构和金属结构屋面的防水工程。特别适用于不宜动用明火的石油库、化工厂、纺织厂、粮库等防水工程。
