Anti-aging modified asphalt waterproof coiled material and preparation method thereof
The invention discloses an anti-aging modified asphalt waterproof coiled material which sequentially comprises a protective layer, an asphalt layer and a substrate layer from top to bottom, the protective layer is a polyethylene layer, and the substrate layer is prepared from HDPE resin, a silane coupling agent A151 and diatomite; the asphalt layer is prepared from the following raw materials: matrix asphalt, modified epoxy resin, unsaturated fatty acid, vinyl trichlorosilane, an SBS thermoplastic elastomer, a light stabilizer, a flame retardant, an antioxidant and filler. According to the waterproof coiled material, unsaturated fatty acid is introduced, a Si-O-Si net structure is formed between oxygen in the unsaturated fatty acid and silicon in vinyl trichlorosilane, the mass ratio of matrix asphalt to modified resin is controlled within a better range, the asphalt layer and the substrate layer are pressed in a heating state, and under the comprehensive action, the waterproof coiled material is not prone to cracking, so that the waterproof coiled material is not prone to cracking. The anti-aging performance and the anti-cracking performance of the coiled material are greatly improved.
本发明公开了一种抗老化改性沥青防水卷材，由上往下依次包括防护层、沥青层以及基底层，所述防护层为聚乙烯层，所述基底层采用的原料包括：HDPE树脂、硅烷偶联剂A151及硅藻土；所述沥青层采用的原料包括：基质沥青、改性环氧树脂、不饱和脂肪酸、乙烯基三氯硅烷、SBS热塑性弹性体、光稳定剂、阻燃剂、抗氧剂、填料。本发明的防水卷材引入不饱和脂肪酸，利用其中的氧和乙烯基三氯硅烷中的硅之间形成Si‑O‑Si网状结构，并且通过将基质沥青和改性树脂的质量比控制在较佳范围，并且在加热状态下对沥青层和基底层进行压紧处理，综合作用下，极大提高了卷材的抗老化性能和抗开裂性能。
