Anti-aging elastomer modified asphalt waterproof coiled material
The invention relates to an anti-aging elastomer modified asphalt waterproof coiled material, and belongs to the technical field of waterproof coiled materials, the anti-aging elastomer modified asphalt waterproof coiled material comprises a base, a modified asphalt layer and a PET film, and the modified asphalt layer comprises the following raw materials: modified asphalt, modified zinc-magnesium-aluminum layered double hydroxide and a filler. According to the technical scheme, the graphene oxide is wrapped through hydrophobic groups on octadecyl, the lipophilicity of the graphene oxide is improved, reduction of the graphene oxide is achieved by adding ascorbic acid, and hydrophilic oxygen-containing functional groups on the surface of the graphene oxide are removed; according to the present invention, the compatibility of the graphene oxide with the asphalt and the SBS is improved, the good compatibility between the asphalt and the SBS is achieved through the octadecylamine-graphene oxide effect, and the stability of the SBS/asphalt material is improved.
本发明涉及一种抗老化弹性体改性沥青防水卷材，属于防水卷材技术领域，该抗老化弹性体改性沥青防水卷材，包括胎基、改性沥青层和PET膜，改性沥青层包括以下原料：改性沥青、改性锌镁铝层状双氢氧化物和填料。本发明技术方案中，通过十八烷基上的疏水基团实现对氧化石墨烯的包裹，增加了氧化石墨烯的亲油性，通过添加抗坏血酸实现对氧化石墨烯的还原，实现将氧化石墨烯表面的亲水性的含氧官能团去除，提高了氧化石墨烯与沥青和SBS的相容性，另外，沥青和SBS之间通过十八烷基胺‑氧化石墨烯的作用而实现了很好的相容，提高了SBS/沥青材料的稳定性。
