一种高初粘性自粘防水卷材及其制备方法
摘要：
本发明公开了一种高初粘性自粘防水卷材，包含以下成分，以质量百分比计：石油沥青35％～55％，软化剂5％～25％，改性剂5％～25％，增粘剂2％～8％，界面剂0.1％～2％，防老剂0.1％～3％，填充剂5％～20％；其中，软化剂为环烷油与芳烃类助溶剂的混合物；改性剂为苯乙烯‑异戊二烯‑苯乙烯嵌段共聚物、热塑性弹性体POE、丁苯橡胶以及丁腈再生胶的混合物；增粘剂为C5石油树脂与液态松香树脂的混合物。本发明的自粘防水卷材具有很好的初粘性，即使在基层表面有少许灰尘，潮湿基层及温度较低的情况下与基层也能够进行良好的粘接，且粘接后不易剥离，能够保证在剥离后在基层上留下完整的改性沥青料，确保较高的防水性能。
摘要（英）：

The invention discloses a self-adhesive waterproof coiled material having high initial stickiness. The coiled material comprises the following components, by mass: 35%-55% of petroleum asphalt, 5%-25% of a softening agent, 5%-25% of a modifying agent, 2%-8% of a tackifier, 0.1%-2% of an interface agent, 0.1%-3% of an anti-aging agent, and 5%-20% of a filling agent. The self-adhesive waterproof coiled material has excellent initial stickiness, even under conditions of a basement layer surface with a little dust, a damp basement layer and a relatively low temperature, the coiled material also has good adhesion with the basement layer, and is not easy to strip after adhesion; after stripping, the coiled material can ensure to leave an integral modified asphalt material on the basement layer, so as to ensure relatively high waterproof performance.
