为了研究内掺硅树脂乳液在水泥基材料中的防水效果及其抗氯离子侵蚀性能,设计了五种不同硅树脂乳液掺量(0、1%、2%、3%、4%)的试验对照组,并对其进行了接触角试验、毛细吸盐试验以及氯离子侵蚀试验,对比分析出此类防水剂功效。结果表明:1%的硅树脂乳液便可以使接触角大于90°,即掺加硅树脂乳液使得水泥基材料具有了憎水性;并且随着掺量的增加,水泥基材料的憎水性愈强,且抗氯离子侵蚀性能也显著增加。
In order to study the water-repellent effect and the resistance to chloride ion attack of cement-based materials with silicon-incorporated emulsions, five different silicone resin emulsions (0,1%, 2%, 3%, 4%) were designed The control group, and its contact angle test, capillary salt absorption test and chloride ion erosion test, comparative analysis of the effectiveness of such waterproofing agent. The results show that 1% silicone emulsion can make the contact angle greater than 90 °, that is to say, the hydrophobicity of cement-based material is enhanced by the addition of silicone emulsion. With the increase of the dosage, the hydrophobicity of cement- And resistance to chloride ion erosion also significantly increased.
