The invention discloses a special waterborne polyurethane waterproof material for a high-speed railway bridge and belong to the technical field of construction engineering waterproof materials. The waterproof material comprises the following components in parts by weight: 60 to 150 parts of waterborne polyurethane; 40 to 80 parts of pure acrylic polymer emulsion; 5-8 parts of plasticizer; 6-10 parts of heat stabilizer; 6-10 parts of accelerant; 5-9 parts of defoaming agent; 2-6 parts of wetting agent; 4-16 parts of water-based dispersing agent; 50-130 parts of superfine calcium carbonate; 14-38 parts of barium sulfate; 10-30 parts of bentonite; and 5-10 parts of anti-aging agent. According to the special waterborne polyurethane waterproof material for the high-speed railway bridge, one ormore of accelerators A, B, C and D are combined; the anti-aging agent is one of an anti-aging agent CPPD, an anti-aging agent IPPD and an anti-aging agent F, and the anti-aging agent is preferably ananti-aging agent F. Different from a traditional waterproof material, the novel waterborne polyurethane waterproof material does not contain phthalate substances, so that the waterproof material causes little pollution to the environment after being used, and meanwhile the waterproof material is good in stability, high in plasticity, relatively low in production cost and suitable for application and popularization.
本发明公开了一种高铁路桥专用的水性聚氨酯防水材料，其原料组成按重量份比包括：水性聚氨酯60‑150份、纯丙烯酸聚合物乳液40‑80份、增塑剂5‑8份、热稳定剂6‑10份、促进剂6‑10份、消泡剂5‑9份、润湿剂2‑6份水性分散剂4‑16份、超细碳酸钙50‑130份、硫酸钡14‑38份、膨润土10‑30份和防老剂5‑10份本发明涉及建筑工程防水材料技术领域。该高铁路桥专用的水性聚氨酯防水材料，通过促进剂A、B、C、D的一种或多种组合，防老剂为防老剂CPPD、防老剂IPPD和防老剂F中的一种，其中防老剂的优选为防老剂F，与传统的防水材料不同，该新型水性聚氨酯防水材料中不含有邻苯二甲酸酯一类物质，该防水材料在使用之后对环境的污染小，同时防水材料的稳定性好，塑性强，生产成本也相对较低，适合推广使用。
