Rheological Behavior of Modified Polyurethane Waterproof-sealing Material
改性聚氨酯防水密封材料的流变特性
Because of the good tensibility and tensile-strength, excellent endurance of water, low temperature, grind, acid and alkali, polyurethane waterproof sealant has been widely used in architecture, water conservancy and public service in America, Japan and other developed countries since 1980s.
由于聚氨酯防水密封胶具有弹性好，伸长率大，强度高，耐磨性突出，耐酸性、耐碱性、耐低温性、耐水性优异，韧性好等特点，所以早在20世纪80年代，美国、日本等经济发达国家的聚氨酯防水密封胶己在建筑、水利和公用设施建设等方面获得了非常广泛的应用。
