Modified asphalt waterproof coiled material for railroad bed and preparation method of modified asphalt waterproof coiled material
The invention relates to a modified asphalt waterproof coiled material for a railroad bed and a preparation method of the modified asphalt waterproof coiled material. The waterproof coiled material sequentially comprises an upper surface isolating layer, a modified asphalt layer, a tire base layer, a modified asphalt layer and a lower surface isolating layer from top to bottom. The modified asphalt layer is prepared from the following raw materials in parts by weight: 90-100 parts of asphalt, 10-15 parts of nitrile rubber, 5-10 parts of SBS (Styrene Butadiene Styrene), 10-20 parts of 1# modified fly ash fiber powder, 3-5 parts of SBR, 10-20 parts of 2# modified fly ash fiber powder, 1-3 parts of a defoaming agent, 3-5 parts of a softening agent and 1-5 parts of a stabilizer. The specially modified fly ash fiber powder is added into the modified asphalt used by the waterproof coiled material, so that the waterproof coiled material has excellent mechanical properties and is used for waterproofing of a railway system.
本发明涉及一种铁路路基用改性沥青防水卷材及其制备方法，防水卷材由上至下依次包括上表面隔离层、改性沥青层、胎基层、改性沥青层和下表面隔离层，改性沥青层由以下重量份数的原料制成：沥青90～100份、丁腈橡胶10～15份、SBS5～10份、1#改性粉煤灰纤维粉10～20份、SBR3‑5份、2#改性粉煤灰纤维粉10～20份、消泡剂1～3份、软化剂3～5份和稳定剂1～5份。本发明防水卷材使用的改性沥青中加入有经过特殊改性的粉煤灰纤维粉，具有优秀的力学性能，使用铁路系统防水使用。
