Environment-friendly high polymer modified asphalt, and waterproof coiled material and preparation method thereof
The invention belongs to the technical field of waterproof materials, and particularly relates to environment-friendly high polymer modified asphalt, and a waterproof coiled material and a preparationmethod thereof. The environment-friendly high polymer modified asphalt comprises the following components in parts by weight: 45-50 parts of petroleum asphalt, 20-25 parts of an ethylene terpolymer,10-15 parts of a sasobit modifier and 1.2-2.5 parts of an antioxidant, wherein the ethylene terpolymer and the sasobit modifier effectively reduce asphalt smoke in the asphalt modification process, the polymer modifier has good compatibility with asphalt, and the homogeneous system is stable. According to the invention, the waterproof coiled material prepared by using the environment-friendly highpolymer modified asphalt as a waterproof middle layer is remarkably improved in the aspects of physical properties, flame retardance and waterproofness, and the preparation method is simple to operate, short in processing period, capable of reducing VOCs emission and outstanding in environmental protection benefit.
本发明属于防水材料技术领域，具体的讲涉及一种环保高聚物改性沥青及其防水卷材和制备方法。该环保高聚物改性沥青包括以下重量份的组分：石油沥青45至50份、乙烯三元共聚物20至25份、sasobit改性剂10至15份、抗氧剂1.2至2.5份。其乙烯三元共聚物及sasobit改性剂在沥青改性过程有效降低沥青烟气且高聚物改性剂与沥青相容性好、均相体系稳定；用该环保高聚物改性沥青作为防水中间层制作的防水卷材，在物理性能和阻燃防水方面具有显著提升，并且该制备方法操作简单、加工周期短，降低VOCs排放，环保效益突出。
