High-strength waterproof coiled material for high-speed rail and preparation method thereof
The invention discloses a high-strength waterproof coiled material for a high-speed rail and a preparation method of the high-strength waterproof coiled material, and belongs to the field of railroadbed construction. The high-strength waterproof coiled material comprises two layers of non-woven geotextile, a composite fiber layer arranged between the non-woven geotextile and a strong rubber layerconnecting the non-woven geotextile with the composite fiber layer. Synthetic fiber interwoven fabric is adopted as the composite fiber layer, so that the integrity of rubberized fabric is improved,the coiled material is easier to form, and the formed waterproof coiled material is tougher and more durable. Chloroprene rubber with excellent aging resistance, water resistance and flame retardanceis adopted as a main material and compounded with ethylene propylene rubber and chlorinated polyethylene, and therefore the stability of the mechanical property of the surface layer is ensured. A rubber blanket for extrusion is sleeved between upper rollers of a three-roller or four-roller calender. Not only is the distribution uniformity degree of the rubber material between the non-woven fabricsimproved, but also the adhesive force between the rubber material and the non-woven fabrics is enhanced, and the mechanical property of the waterproof coiled material is improved.
本发明公开了一种高铁用高强度防水卷材及其制备方法，属于铁路路基建设领域。包括：两层无纺土工布，设置在所述无纺土工布之间的复合纤维层，以及连接所述无纺土工布与所述复合纤维层的强力橡胶层。本发明采用合成纤维交织布作为复合纤维层，增加胶布的整体性，更易成型，其所形成的防水卷材更为强韧、耐用。采用耐老化、耐水性、阻燃性能卓越的氯丁橡胶为主材，与乙丙橡胶、氯化聚乙烯复合配制，得到从而确保面层的机械性能的稳定性。通过在三辊或四辊压延机上辊筒之间套装有挤压用的橡胶毯。不仅提高了橡胶材料在无纺布之间分布的均匀程度，也加强橡胶材料与无纺布之间的附着力，提高了防水卷材的机械性能。
