Polyolefin elastomer film self-adhesive asphalt waterproof coiled material as well as preparation method and application thereof
The invention relates to a polyolefin elastomer film self-adhesive asphalt waterproof coiled material and a preparation method and application thereof. The coiled material comprises a polyolefin elastomer film layer, a barrier bonding layer, a self-adhesive polymer modified asphalt layer and an isolating film layer which are sequentially arranged, the self-adhesive polymer modified asphalt layer is prepared from the following raw materials: petroleum asphalt, tackifying resin, a modifier, softening oil and filler, the mass ratio of the petroleum asphalt to the tackifying resin to the modifier to the softening oil to the filler is (40-50): (2-10): (5-20): (5-25): (15-35), the filler at least contains modified powder, and the modified powder is silica powder or quartz powder of which the surface is modified by an amino silane coupling agent. Through the arrangement of the barrier bonding layer, the polyolefin elastomer and the modified asphalt can be isolated from each other and do not influence each other, the long-term stability of the waterproof roll is improved, the polyolefin elastomer film layer and the self-adhesive polymer modified asphalt layer can be firmly bonded together, separation of an adhesive film is avoided, and the service life of the waterproof roll is prolonged. And the long-term stability and reliability of the waterproof roll are improved.
本发明涉及一种聚烯烃弹性体膜自粘沥青防水卷材及其制备方法和应用，该卷材包括依次设置的聚烯烃弹性体膜层、阻隔粘接层、自粘聚合物改性沥青层和隔离膜层，自粘聚合物改性沥青层的原料包含石油沥青、增粘树脂、改性剂、软化油和填料，石油沥青、增粘树脂、改性剂、软化油、填料的质量比为40～50:2～10:5～20:5～25:15～35，其中，填料至少含有改性粉料，改性粉料为表面经过胺基硅烷偶联剂改性的硅微粉或石英粉。本发明通过阻隔粘接层的设置，不仅能够使聚烯烃弹性体和改性沥青两种材料相互隔离，使其互不影响，提高防水卷材的长期稳定性，同时又能够将聚烯烃弹性体膜层和自粘聚合物改性沥青层可以牢固的粘接在一起，避免胶膜分离，提高防水卷材的长期稳定性和可靠性。
