石油沥青玛蹄脂是以石油沥青加粉状或纤维填充剂制成的一种胶合材料。在常温下是固体,与石油沥青相似;在高温下熔融而成粘稠物。它的用途是在建筑防水层时用它来胶合防水卷材,保证多层防水层的坚固耐久性。石油沥青玛蹄脂是被填充了的沥青,填充料不论是微粒或纤维,填充到沥青之后都被沥青胶体包裹而形成了悬浮体,这样就增加了有机结合体分子与分子间的摩擦力,并且增加了表面吸引力,因而在同样软 Petroleum asphalt Mastic is a glue made from petroleum asphalt plus powder or fiber fillers. It is solid at room temperature and is similar to petroleum asphalt; it melts at high temperatures to form a viscous material. Its purpose is to use it to glue waterproof membranes when building a waterproof layer, ensuring the robust durability of the multilayer waterproof layer. The asphalt is filled with bitumen. The filler, whether it is particles or fibers, is encapsulated in asphaltic colloids to form a suspension. This increases the friction between the molecules and the molecules of the organic combination. And increase the surface attractiveness, and thus in the same soft
