青岛地区近年利用氯丁橡胶先后制成氯丁-1、氯丁-2两种新型防水材料。以此制成的沥青基涂料具有较好的防水效果,经上万平方米的施工实践,证明效果良好。一、技术性能氯丁-1是一种新型溶剂型氯丁橡胶-沥青防水涂料,比重约为1,总固量为30％,冰点为-3℃,耐热80℃,加热5小时涂膜无起鼓、起泡及流淌现象;低温柔性为-40℃冷冻2小时后,在φ5mm轴棒上弯曲180°,涂膜无裂缝;低温抗裂性为-10℃;基层开裂宽度大于0.6mm时,涂膜不裂;不透水性为在动水压力2kgf/cm~2(约0.2MPa)作
In recent years, Qingdao has made use of neoprene rubber has made neoprene-1, neoprene-2 new waterproof material. The asphalt-based coating made of this material has a good waterproof effect. After tens of thousands of square meters of construction practice, it proves that the effect is good. First, technical performance neoprene-1 is a new type of solvent-based neoprene-asphalt waterproof coating, the specific gravity is about 1, the total solid volume is 30%, the freezing point is -3 °C, heat 80 °C, heating 5 hours film No druming, bubbling and flow phenomenon; low temperature flexibility is -40 °C frozen for 2 hours, bent on the φ5mm shaft 180 °, no cracks in the coating; low temperature crack resistance of -10 °C; base cracking width greater than 0.6mm When the coating film does not crack, the water impermeability is at the hydrodynamic pressure of 2kgf/cm~2 (about 0.2MPa).
