单组份柔性防水灰浆的研究

Exploratory study on one-component flexibility waterproof coating

研究纯丙烯酸胶粉掺量对柔性防水灰浆拉伸粘结强度、抗压抗折强度、涂层抗渗压力以及横向变形等性能的影响,结果表明,丙烯酸胶粉6041A掺量7.5%以上时,可以配制出满足1.5 mm薄层涂刷施工,48 h闭水试验不透水,横向变形达到5.0 mm以上的单组份柔性防水灰浆,并对防水机理进行了初步探讨。单组份柔性防水灰浆是性能优越、市场应用前景广阔的一种产品。

The influence of powder content on properties of flexible waterproof slurry is studied. By testing the properties of tensile bond strength,compressive flexural strength,impermeability test system as well as horizontal variations,the result shows that superior performance of one-component flexible waterproof coating can be obtained,with eopolymer of acrylate powder 6041A,the content of 7.5%,meeting the 1.5 mm thin brushing construction,ensuing impermeable in 48 h closed water test, and horizontal deformation more than 5.0 mm. Furthermore,its waterproof mechanism is preliminary discussed, showing the one-component flexible waterproof coating has a broad market because of its superior character.
