The invention relates to the field of building materials, and particularly discloses a bridge expansion joint filling material and a preparation method thereof. The bridge expansion joint filling material is prepared from the following raw materials in parts by weight: 10 to 20 parts of polyurethane resin, 1 to 3 parts of titanium dioxide, 6 to 8 parts of cement, 2 to 4 parts of mineral powder, 4 to 8 parts of magnetic particles, 0.1 to 0.3 part of curing agent, 0.5 to 1 part of dispersing agent and 5 to 10 parts of water. The polyurethane resin is waterborne polyurethane; the preparation method comprises the following steps: adding the magnetic particles and the polyurethane into an acetone solution, carrying out ultrasonic treatment, heating to 40-50 DEG C, sequentially adding the curing agent, the titanium dioxide, the mineral powder, the cement and the dispersing agent, and uniformly stirring to obtain a mixture; and filling a mold with the mixture, applying a uniform magnetic field, and taking out the mixture after curing molding to obtain the bridge expansion joint filling material. The composition can be used for filling bridge expansion joints, and has the advantage of high tensile strength.
本申请涉及建筑材料领域，具体公开了一种桥梁伸缩缝填充材料及其制备方法。一种桥梁伸缩缝填充材料，如下重量份原料：聚氨酯树脂10‑20份、二氧化钛1‑3份、水泥6‑8份、矿粉2‑4份、磁性颗粒4‑8份、固化剂0.1‑0.3份、分散剂0.5‑1份、水5‑10份；所述聚氨酯树脂为水性聚氨酯；其制备方法为：将磁性颗粒与聚氨酯加入丙酮溶液中超声处理后，加热至40‑50℃后，依次加入固化剂、二氧化钛、矿粉、水泥以及分散剂搅拌均匀，得到混合物；将所述混合物填充到模具中，施加匀强磁场，等待固化成型后取出，得到所述桥梁伸缩缝填充材料。本申请的组合物可用于桥梁伸缩缝的填充，其具有抗拉强度高的优点。
