发布日期:2019-12-11

   

SBS改性沥青防水卷材是以SBS橡胶改性沥青、聚酯纤维无纺布、黄麻布、玻璃纤维毡等为胎底,塑料薄膜为防粘隔离层而成。采用选材、配料、共熔、浸渍、复合成型、压接等工艺加工制造。它具有抗拉强度高、延伸率高、耐高低温、耐老化等特点。适用于一、二、三级屋面防水、地下室防水、纸房防水、水库防水、隧道防水、水利工程防水。

部件的影响和调整

1沥青

沥青的延展性和含蜡量对粘结性能有重要影响。除要求25℃时沥青的延性大于100cm外,蜡含量不宜过多,否则将直接影响粘结性能。此外,沥青的溶解度也有一定的影响。使用的沥青不应含有过多的沥青质、游离碳和机械杂质,以保证粘结性。

2SBS公司

SBS改性沥青时,沥青与SBS的相容性非常重要。所谓良好的相容性,是指所选的沥青和SBS熔融指数适中,效果较好。s b s是苯乙烯(s)和丁二烯(b)的嵌段共聚物,其中丁二烯为软段,为连续相;苯乙烯(s)两端为硬段,聚合成物理交联区。不同的嵌段比(s/b)对键合性能有一定的影响。
