摘要
以HDI、OxyesterT 1 1 36聚酯、DMPA等为原料合成水乳液。研究了乳液成膜物的耐水解和物理性能。结果表明 ,此种聚酯型聚氨酯有较优良的耐水解性 ,良好的力学性能及较低的玻璃化转变温度。
Aqueous polyurethane emulsion is prepared by HDI, Oxyester T?1?136, DMPA, etc. The hydrolysis and mechanical properties of PU films from the emulsion are discussed. The results show that the emulsion gives films excellent hydrolysis resistance, high tensile strength, better hardness and lower Tg.
