The invention relates to the technical field of coiled materials for rail transit, and discloses a soft sound insulation coiled material for rail transit, which comprises a styryl thermoplastic elastomer modified base material, and one or more of a non-woven fabric and an aluminum foil, the styryl thermoplastic elastomer modified base material is prepared from the following components in parts by mass: 6 to 10 parts of styryl thermoplastic elastomer resin base material, 20 to 28 parts of plasticizer, 60 to 90 parts of powder filler, 80 to 120 parts of flame-retardant modifier, 2 to 3 parts of lubricant, 0.3 to 0.6 part of antioxidant and 1 to 3 parts of tackifier; the preparation method comprises the following steps: mixing and soaking the styryl thermoplastic elastomer resin base material and the plasticizer to obtain a filling base material; and other assistants are mixed, so that the styrene-based thermoplastic elastomer resin base material fully absorbs the plasticizer, and the filling of more fillers is realized on the basis of low-content base material, that is, the obtained material is good in sound insulation effect and low in hardness.

    本发明涉及轨道交通用卷材技术领域,公开了一种轨道交通用软质隔声卷材,包括苯乙烯基热塑性弹性体改性基材、以及无纺布、铝箔中的一种或多种;按质量份数计,所述苯乙烯基热塑性弹性体改性基材包括苯乙烯基热塑性弹性体树脂基料6‑10份、增塑剂20‑28份、粉体填充物60‑90份、阻燃改性剂80‑120份、润滑剂2‑3份、抗氧剂0.3‑0.6份和增粘剂1‑3份;制备时,先取苯乙烯基热塑性弹性体树脂基料和增塑剂,混合浸泡,得到填充基料;再混入其他助剂,使苯乙烯基热塑性弹性体树脂基料充分吸收增塑剂,在低含量基料的基础上,实现更多填料的填充,即所得材料隔声效果好、硬度低。
