摘要:SBR作为自粘聚合物改性沥青防水卷材中一种重要的改性剂,其掺量对自粘聚合物改性沥青的性能影响明显。试验结果表明,随着SBR掺量的增大,自粘聚合物改性沥青的低温柔性提高,持粘时间延长,剥离强度增大。SBR可完全替代自粘聚合物改性沥青配方中的萜烯树脂,在不影响其耐热性的前提下,不仅可提高其低温柔性,还可显著提高其持粘性和剥离强度,进而改善卷材的粘结性能。

Abstract:SBR is an important modifier in self-adhesive polymer modified asphalt waterproofing roll. The different content of SBR has obvious influence on the performance of self-adhesive polymer modified asphalt. It was found by experiment that with the increase amount of SBR,the low temperature flexibility of self-adhesive polymer modified asphalt increased,the sticky time expand,and the peeling strength increased. The results show that SBR can completely replace terpene resin in self-adhesive polymer modified asphalt formulation. Without affecting its heat resistance,SBR can not only improve its low temperature flexibility,but also significantly improve its adhesion and peeling strength,thereby improving the bonding performance of waterproofing roll.
