Elastic modified asphalt waterproof coiled material and preparation method thereof
The invention discloses an elastic modified asphalt waterproof coiled material which is characterized in that the coiled material sequentially comprises an upper modified asphalt layer, a tire base layer and a lower modified asphalt layer from top to bottom; isolating membrane layers are independently laid on the upper surface of the upper modified asphalt layer and the lower surface of the lower modified asphalt layer respectively; and the upper modified asphalt layer and the lower modified asphalt layer are made of the same materials, and are each prepared from the following components in parts by weight: 65-75 parts of asphalt, 3-5 parts of hyperbranched poly (urethane-amine) of which the end group is hydroxyl and the internal branched unit is provided with vinyl, 2-4 parts of methyl vinyl silicone rubber, 4-7 parts of dichloro-terminated polydimethylsiloxane/2, 5-bis (diethylamino) phenyl-1, 3, 4-diazole polycondensate, 3-5 parts of sulfonated ethylene propylene diene monomer and 0.3-0.5 parts of an initiator. The elastic modified asphalt waterproof coiled material disclosed by the invention is remarkable in waterproof effect, good in high temperature resistance, mechanical property and anti-aging property, and long in wear resistance and service life.
本发明公开了一种弹性改性沥青防水卷材，其特征在于，自上而下依次包括上改性沥青层、胎基层和下改性沥青层；所述上改性沥青层的上表面上和下改性沥青层的下表面上分别相互独立地铺设有隔离膜层；其中，所述上改性沥青层和下改性沥青层所用材料相同，均是由如下按重量份计的各组分制成：沥青65‑75份、端基为羟基内部支化单元带有乙烯基的超支化聚(氨酯‑胺)3‑5份、甲基乙烯基硅橡胶2‑4份、双氯封端聚二甲基硅氧烷/2,5‑双(二乙基氨基)苯基‑1,3,4‑二唑缩聚物4‑7份、磺化三元乙丙橡胶3‑5份、引发剂0.3‑0.5份。本发明公开的弹性改性沥青防水卷材防水效果显著，耐高温性能、机械力学性能和抗老化性能好，耐磨性和使用寿命长。
