SBS和APP树脂石油沥青防水卷材的研制

Development of Water - proof Petroleum Pitch Coiled Material Modified by SBS and APP Resins

用ＳＢＳ或ＡＰＰ树脂改性的石油沥青所制成的防水卷材，具有良好的防水性能、抗高温变形能力和抗寒性能，正逐步替代ＰＶＣ煤焦油防水卷材。

The water - proof coiled material made of petroleum pitch which is modified by SBS and APP resins has a good water - proof property, good ability to resist deformation under high temperature and property of cold resistance. It is substituted for the coiled material of PVC coal tar gradually.
