不同原材料对改性沥青防水卷材可溶物含量的影响

Influences of Different Raw Materials on the Solvent Content of Modified Bitumen Waterproofing Membrane

研究了4种不同油品和4种不同胶粉对改性沥青可溶物含量的影响,得出结论:不同油品和胶粉对改性沥青可溶物含量的影响是不同的,在基础油、橡胶油、废机油和芳烃油四种油品中,废机油对可溶物含量的贡献度最差;活化过的胶粉与沥青和油品的相容性相对较好,且易溶解,对可溶物含量的贡献也相对较大;改性共混温度过高会对可溶物含量造成损失。

The article studies the influences of 4 different oils and 4 different rubber powders on the solvent content of modified bitumen, and it concludes different oil and rubber powder has different influences on the solvent content of modified bitumen. Among base oil, rubber oil, used engine oil and aromatic oil, used engine oil has the least contribution to the solvent content. Activated rubber powder has better compatibility with bitumen and oil. It is easy to be dissolved and contributes more to the solvent content. Modification and blending at excessive high temperature will cause a loss to the solvent content.
