Elastic insulating adhesive and application thereof in insulating repair of rail gaps between rails
The invention discloses an elastic insulating adhesive and application thereof in insulating repair of a rail gap between rails, and belongs to the technical field of train safe operation protection. The rail seam comprises a rail seam between the rail heads and an insulating clamping piece damage sunken part between the rail seams; the curing temperature of the elastic insulating adhesive is-15-50 DEG C, the curing time is 1-120 min, the steel/steel tensile-shear strength is larger than or equal to 5 MPa, and the Shore A hardness is larger than or equal to 75. The adhesive disclosed by the invention is applied to the aspect of rail repair, and solves the problems of scrap iron accumulation and fat edge overlapping in a damaged groove of a rail gap insulating sheet, and the problem of poor repair effect when the adhesive is used for a rail gap between rail heads and a damaged concave part of an insulating clamping sheet between the rail gaps due to performance defects of an existing adhesive.
本发明公开了一种弹性绝缘胶黏剂及其在铁轨间轨缝绝缘修复中的应用，属于列车安全运行防护技术领域。铁轨轨缝包括铁轨轨头之间的轨缝以及轨缝之间绝缘夹片破损凹陷部位；弹性绝缘胶黏剂的固化温度为‑15‑50℃，固化时间1‑120min，钢/钢拉剪强度≥5MPa，邵氏A硬度≥75。本发明应用于轨道修复方面，解决轨缝绝缘片破损凹槽中铁屑堆积以及肥边搭连的问题，以及现有胶黏剂因性能上的缺陷造成在用于铁轨轨头之间的轨缝以及轨缝之间绝缘夹片破损凹陷部位的修复时效果不佳的问题。
