中文摘要：

在这研究，几种灵活保护的材料与 polyurea 弹性体喷洒了(以下把保护的材料叫作 polyurea 弹性体) 被采用与推迟的负担对水流动满足水力的结构，和他们的磨损电阻的磨损抵抗要求或床负担通过测试系统地被学习。自然暗岩石头与床负担为水流动的磨损效果的模拟作为磨料被采用，并且测试结果显示暗岩石头对在灵活保护的材料的磨损抵抗测试的使用合适。polyurea 弹性体的 wear 过程保护的材料是稳定的，并且 wear 损失与磨损的时间是线性的。如果wear 厚度被认为是磨损抵抗评估因素， 351 纯 polyurea 的磨损抵抗在附近两次那些有坚硬的高水平的纯 polyurea 和脂肪族的 polyurea ，并且乘在水的磨损下面的高效的磨损抵抗的水泥的的超过五与推迟的负担流动。它也是在有床负担的水流动的磨损下面的高效的磨损抵抗的水泥的大约 50 次。总的来说，纯 polyurea 的磨损抵抗与增加坚硬介绍了一个减少的趋势。有 D30 的岸坚硬的纯 polyurea 有最好的磨损抵抗，它是乘在有床负担的水流动的磨损下面的高效的磨损抵抗的水泥的的 60～70 ，并且与不同坚硬在五种纯 polyurea 材料之中被推荐了，在水力的结构的反磨损保护。

英文摘要：

In this study, several kinds of flexible protective materials sprayed with polyurea elastomers （hereinafter referred to as polyurea elastomer protective material） were adopted to meet the abrasion resistance requirement of hydraulic structures, and their abrasion resistances against the water flow with suspended load or bed load were studied systematically through tests. Natural basalt stones were adopted as the abrasive for simulation of the abrasion effect of the water flow with bed load, and test results indicate that the basalt stone is suitable for use in the abrasion resistance test of the flexible protective material. The wear process of the polyurea elastomer protective material is stable, and the wear loss is linear with the time of abrasion. If the wear thickness is regarded as the abrasion resistance evaluation factor, the abrasion resistance of the 351 pure polyurea is about twice those of pure polyurea with a high level of hardness and aliphatic polyurea, and over five times that of high-performance abrasion-resistant concrete under the abrasion of the water flow with suspended load. It is also about 50 times that of high-performance abrasion-resistant concrete under the abrasion of the water flow with bed load. Overall, the abrasion resistance of pure polyurea presented a decreasing trend with increasing hardness. Pure polyurea with a Shore hardness of D30 has the best abrasion resistance, which is 60 to 70 times that of high-performance abrasion-resistant concrete under the abrasion of the water flow with bed load, and has been recommended, among the five kinds of pure polyurea materials with different hardness, in anti-abrasion protection of hydraulic structures.
