【摘要】：自从改革开放以来,我国的基础建设一直保持较快的增长速度,防水已经从传统的房屋建筑工程,慢慢过渡延伸到公路、铁路、桥梁、地下、水利及机场等各个工程领域,因而对防水技术水平提出了更高的要求。非固化橡胶沥青防水涂料具有自愈合、防窜水、抗渗漏以及耐老化等综合性能,但该类材料具体性能与最优的工程应用实施方案尚需要进一步探索,本文依托香格里拉防水工程对DSTD(Dihydroxy Secoandrosta Tetraene Dione)系列非固化橡胶沥青基防水涂料的性能进行对深入研究。具体研究内容如下:(1)对DSTD系列非固化橡胶沥青防水涂料的配方配合比对防水涂料粘性、低温柔性和剪切与粘结强度的影响进行了试验研究得到如下结论:(a)增粘剂含量对粘聚力有一定影响,调整增塑剂和增粘剂之间的比例,可使涂料的粘结性能达到比较理想的效果;(b)当10号沥青掺量在10%以内时,低温柔性逐渐下降;当其掺量超过10%时性能下降比较剧烈,鉴于此,调整涂料性能时若需要掺10号沥青时,其掺量应控制在10%以内;(c)10号沥青的掺入对涂料粘结强度影响较为明显,从总体来看控制其掺量在10%内时,剪切粘接强度可达到2.9N/mm左右。(2)基于DSTD非固化橡胶沥青基防水涂料在香格里拉二期项目中的应用,本文在参考国内外相关防水设计规范的基础上,针对不同类型的防水工程,首次系统设计了非固化橡胶材料的防水施工工艺和防水细节施工措施,并最终达到良好的防水效果。(3)提出了DSTD集成防水防护系统,该系统打破了常规的理念,完全颠覆防水卷材和防水涂料的概念,和基层完全满粘、内应力极强、具有蠕动性和跟随性、又不成膜的涂料,与防水卷材复合使用可以将该防水涂料与防水卷材的优势发挥到极致,真正达成“皮肤式”防水层,从下往上防水材料的刚度依次从柔性、半刚性到刚性,给予建筑更持久的防水保护,完全使渗漏问题从根本上得到标本兼治地解决。
[Abstract]:Since the reform and opening up, China's infrastructure has maintained a rapid growth rate, waterproof has been from the traditional housing construction projects, slowly extended to roads, railways, bridges, underground. Water conservancy and airport and other engineering fields, so the level of waterproofing technology put forward higher requirements. Uncurable rubber asphalt waterproof coating has self-healing, anti-channeling, anti-leakage and anti-aging comprehensive properties. However, the concrete properties of this kind of materials and the optimal engineering application scheme need to be further explored. This article relies on the Shangri-La waterproof project to DSTD(Dihydroxy Secoandrosta Tetraene Dione). The performance of series of uncurable rubber asphalt based waterproofing coatings is studied. The specific research contents are as follows: 1) the formula mix ratio of DSTD series uncurable rubber asphalt waterproof coatings is viscous to waterproof coatings. The effects of low temperature flexibility and shear and bond strength were studied. The conclusions are as follows: (1) the content of tackifier has a certain effect on the cohesion, and the ratio between plasticizer and tackifier is adjusted. The adhesive property of the coating can reach the ideal effect; When the content of No. 10 pitch is less than 10%, the low temperature flexibility decreases gradually. When the amount of asphalt is more than 10, the performance will decrease sharply. In view of this, if it is necessary to add 10 asphalt to adjust the performance of the coating, the content of the asphalt should be controlled within 10%. The influence of 10 asphalt on the bond strength of the coating is obvious, when the content of the asphalt is controlled within 10% as a whole. Shear bonding strength can reach 2.9N / mm or so.) the application of non-curing rubber bitumen based waterproof coating based on DSTD in Shangri-La Phase II project. On the basis of referring to the domestic and foreign relevant waterproof design codes, the waterproofing construction technology and waterproof detail construction measures of non-curing rubber materials are designed systematically for different types of waterproofing projects for the first time. And finally achieve a good waterproof effect. 3) put forward the DSTD integrated waterproof protection system, this system breaks the conventional idea, completely subverts the concept of waterproof membrane and waterproof coating, and the base completely sticky. The internal stress is very strong, has the creeping and follows the property, and does not form the film the coating, and the waterproof membrane compound use may bring this waterproof coating and the waterproof membrane superiority to the extreme, truly achieves "the skin type" waterproof layer. The stiffness of waterproofing material from bottom to top is from flexibility, semi-rigidity to rigidity, which gives the building more lasting waterproof protection, and completely solves the problem of leakage at both the root and the root.
