在卷材屋面防水施工中,由于低标号沥青供应不足,很多施工单位常采用单一的高标号沥青配制玛(王帝)脂,这对保证防水工程施工质量很不利,应设法改变这种状况。玛(王帝)脂是采用在石油沥青中加一些填充料、增韧剂和溶剂配制而成的。用玛(王帝)脂代替纯沥青做防水层卷材的粘结剂,不仅可以改善纯沥青的冷脆性和粘结力并提高防水层的耐热性,还能节约沥青用量。用低标号沥青配制玛(王帝)脂,既能提高耐久性,又能保持良好的施工性能和防水性
In the waterproof construction of coiled roofs, due to the insufficient supply of low-grade asphalt, many construction units often use a single high-grade asphalt to formulate Ma (Dili) grease, which is very unfavorable for guaranteeing the construction quality of waterproof works, and we should try to change this situation. Ma (Dili) fat is formulated by adding some filler, toughener and solvent to petroleum asphalt. The use of Ma (Wang Di) grease instead of pure asphalt as a binder for the waterproof layer membrane can not only improve the cold brittleness and cohesive force of pure asphalt, but also improve the heat resistance of the waterproof layer, and can also save the amount of asphalt. The use of low-grade bitumen to formulate Ma (Wang Di) grease can not only improve durability, but also maintain good construction performance and water resistance.
