无规聚丙烯是聚丙烯生产中大量排出的一种工业废料,为了利用它作为建筑防水材料,我所进行了试验研究,取得了良好的效果。这种防水材料,系将无规聚丙烯与10号沥青或60号沥青分别加热后,按一定的比例混合配制而成;也可将上述材料按比例混合后共同加热制成。这种防水材料与单用沥青相比,软化点、耐热度都有所提高,在常温和低温下的柔韧度以及人工气候老化性能均较良好。在我局一些工程上应用,受到工人和技术人员的欢
Atactic polypropylene is a kind of industrial waste that is discharged in large quantities from polypropylene production. In order to use it as a building waterproof material, I conducted a pilot study and achieved good results. The waterproof material is prepared by mixing atactic polypropylene with bitumen No. 10 or bitumen No. 60, and then mixing them according to a certain ratio. The above materials may also be mixed and heated together. Compared with asphalt used alone, this waterproof material has improved softening point and heat resistance, and has good flexibility at normal temperature and low temperature and artificial weathering performance. Applied in some projects of our bureau, welcomed by workers and technicians
