| 本文针对目前常用的薄层抗冲磨防护材料难以抵抗高速水流推移质磨蚀破坏难题，以柔性氨基树脂材料和特种固化剂为胶结体系，添加抗冲磨填料，研发了一种新型抗冲磨树脂砂浆材料。并对新型树脂砂浆进行了力学性能、冲磨能力和环境适应性试验，试验结果表明砂浆伸长率在5%以上，与基面黏接强度大于2.5MPa，表明其具有良好的抗裂能力和适应变形的能力；水下钢球法冲磨试验3个周期质量基本没有损失，同等条件下圆环法冲磨对比试验证明其抗冲磨强度是高强环氧砂浆的5倍以上，证明新型抗冲磨树脂砂浆具有高弹韧性的材料特性，适用于泄水建筑物的抗冲磨、特别是推移质破坏的防护和修复。 |

| This paper aim at the problem of abrasion damage by bed load in high-speed flow, based on the flexible amino resin material and special curing agent for cement system, adding anti abrasion fillers, developed a new type of special abrasion resistant resin mortar material. And tested the mechanical properties、abrasion resistance and environmental adaptability, results show that the elongation of mortar is over 5%, and the base bonding strength is greater than 2.5MPa. It shows that the mortar material has good crack resistance and deformation adaptability. The comparative test of ring abrasion shows that its abrasion resistance is 5 times of the high strength epoxy mortar. It proved that the new abrasion resistant resin mortar has the material characteristics of "combining rigidity with flexibility",suitable for the protection and repair of abrasion resistance for drainage structures,especially for bedload damage. |
