1 目的和意义近年来,我国先后引进了9条新型沥青防水卷材生产线。产品使用中,传统的热沥青法能耗较大,环境污染严重。而现有的冷胶粘剂产品中,冷玛脂适用范围较窄,而以氯丁胶、SBS 为改性材料的冷胶粘剂则价格偏高。研究开发与新型沥青防水卷材相配套、价格合理、适应多种不同层次需求的橡胶改性沥 1 Purpose and significance In recent years, China has introduced nine new asphalt waterproof coiled material production lines. In the use of products, the traditional hot asphalt method consumes more energy and the environment is seriously polluted. However, in the existing cold adhesive products, the application range of cold grease is narrow, and cold adhesives using neoprene and SBS as the modified materials are expensive. Research and development of rubber modified asphalt matched with new bituminous waterproof membranes at reasonable prices and adapted to various levels of demand
