道桥用水性聚合物改性沥青防水涂料的研究

Study on Aqueous Polymer Modified Asphalt Waterproofing Coating for Road and Bridge

摘要: 先制得SBS改性乳化沥青，再复合使用一定量氯丁胶乳进一步提升产品性能，并加入少量自制复合稳定剂制得最终产品。SBS的引入，在保证材料性能的前提下，减少了CRL的用量，不仅降低了成本，还提高了产品储存稳定性。自制复合稳定剂的加入，进一步提高产品稳定性，使产品适合长期储存。本研究通过试验，确定了SBS用量、氯丁胶乳用量和稳定剂用量，在使用较少量氯丁胶乳的情况下，制得稳定性良好，且物理性能优异的道桥用水性聚合物改性沥青防水涂料。

Abstract: SBS modified asphalt emulsion is prepared first, and then a certain amount of neoprene latex is used to further enhance the product performance; last a small amount of homemade composite stabilizer is added to obtain the final product. On the premise of ensuring the material properties, adding SBS can reduce the amount of the CRL, which not only reduces costs, but also improves the storage stability of the product. Self-made composite stabilizer added can further enhance product stability, so that the product is suitable for long term storage. The amount of SBS, neoprene latex and stabilizer is determined by test, to obtain an aqueous polymer modified asphalt waterproofing coating for road and bridge with good stability and excellent physical properties, in the case of using a relatively small amount of neoprene latex.
