摘　　要：在日常检测中,聚合物水泥防水涂料委托方提供乳液、粉料及水的比例范围,若检验人员在试样制备时使用了不同的配比,会导致聚合物水泥防水涂料拉伸性能试验结果出现较大离散性。本文详细介绍了聚合物水泥防水涂料拉伸性能试样制备方法,对比分析了不同配比对试验结果的影响。结果表明,聚合物水泥防水涂料拉伸性能试验过程中,精确控制水的用量对于确保试验结果的准确性至关重要。在此基础上,提出了对GB/T 23445—2009《聚合物水泥防水涂料》标准的修订建议。In routine examination,clients often provide ratio ranges for emulsion,powder and water in polymer cement waterproofing coatings.Inspectors using different ratios during sample preparation may cause significant variability in tensile tests.This study details the sample preparation method for tensile performance testing of polymer cement waterproofing coatings and comparatively analyzes the effects of different ratios on results.The results indicate that the precise control of water content is crucial for ensuring the accuracy of tensile performance test results.Based on these results,the study proposes amendments to the GB/T 3445—2009“Polymer-modified cement compounds for waterproofing membrane”.
