Hot-melt rubber asphalt waterproof coating with remarkably improved peel strength as well as preparation method and application of hot-melt rubber asphalt waterproof coating
The invention relates to a hot-melt rubber asphalt waterproof coating with significantly improved peel strength, and a preparation method and application thereof. The waterproof coating comprises asphalt, tackifying resin, softening oil, a polymer modifier, an inorganic anti-stripping agent and an organic anti-stripping agent, the pH value of the inorganic anti-stripping agent is 12-14, the polymer modifier is a linear styrene-butadiene-styrene block copolymer and styrene butadiene rubber, and the organic anti-stripping agent is a styrene-butadiene rubber. The mass ratio of the asphalt to the tackifying resin to the softening oil to the linear styrene-butadiene-styrene block copolymer to the styrene butadiene rubber is (30-40): (5-10): (15-25): (4-7): (2-4). The waterproof coating can be used for a waterproof laminated body, and comprises a base material layer, a waterproof coating and an asphalt-based waterproof roll layer, or an asphalt-based waterproof roll layer, a waterproof coating and an asphalt-based waterproof roll layer. The waterproof coating has excellent adhesive property, peel strength and peel strength retention rate after water immersion with a cement base layer or an asphalt-based waterproof coiled material.
本发明涉及一种剥离强度显著提高的热熔橡胶沥青防水涂料及其制备方法和应用。防水涂料的组分包括沥青、增粘树脂、软化油、聚合物改性剂、无机抗剥落剂和有机抗剥落剂，无机抗剥落剂的pH值为12‑14，聚合物改性剂为线性苯乙烯‑丁二烯‑苯乙烯嵌段共聚物和丁苯橡胶，沥青、增粘树脂、软化油、线性苯乙烯‑丁二烯‑苯乙烯嵌段共聚物和丁苯橡胶的质量比为30‑40：5‑10：15‑25：4‑7：2‑4。该防水涂料可用于防水层叠体，其包括基材层、防水涂层、沥青基防水卷材层，或沥青基防水卷材层、防水涂层、沥青基防水卷材层。该防水涂料与水泥基层，或者与沥青基防水卷材都具有优异的粘结性能，剥离强度和浸水后剥离强度保持率。
