摘　　要：近年来,高速公路两侧路缘石及桥梁防撞墙受融雪剂腐蚀的问题越来越严重,融雪剂清理积雪造成的混凝土腐蚀破坏逐渐成为高速公路养护的重大难点。以聚氨酯改性环氧树脂为基料开发了一种水性混凝土防腐涂料,研究了涂料的耐水性、耐腐蚀性、耐候性、附着力等性能,并对涂料进行施工应用,达到限制融雪剂对高速公路混凝土腐蚀的目的。In recent years, the issue of corrosion of curbs and bridge bump wall on both sides of highway by snow melting agent has gotten more and more serious, and it has gradually become a major dififculty in highway maintenance that the concrete is corroded and damaged resulting from clearance of accumulated snow with snow melting agent. A kind of waterborne concrete anticorrosion coatings based on the polyurethane modiifed epoxy resin, such performances of the coatings as water resistance, corrosion resistance, weather fastness and adhesiveness, etc. are researched, and the paint is applied. Thus, the purpose of limiting the highway concrete corrosion by snow melting agent is achieved.
