中文摘要 | 水性PU樹脂乃是以不同分子量之聚醚或聚酯等聚醇類為軟質部份,異氰酸類為其硬質部份為主要結構。一旦加入EPO系列之內乳化劑為離子中心時,成為具高強力、高伸長率及低模數及高透濕度之透濕型水性PU樹脂。 |
英文摘要 | The polyurethane dispersions was composed of soft and hard segments in which the soft segment used was polyether or polyester poly of different molecular weight and the hard segment was diisocyanate. Once added the ethylene peroxide (EPO)into the Polyurethane dipersions as internal emulsifying agents, it became to a high strength ,high elongation , low modulus and high water-vapor-permealility of polyurethane dispersions. |
