醇酯型聚氨酯油墨连接料的制备与性能研究

Preparation of Ethanol and Ester-Soluble Polyurethane for Ink Binder and Study on Its Property

采用聚酯二元醇PBA和PEDA及自制的扩链剂与甲苯二异氰酸酯进行逐步反应,制备了醇酯型聚氨酯油墨连接料,并通过傅里叶红外光谱仪对其进行表征。分析了PBA和PEDA的质量配比对合成的聚氨酯性能的影响。结果表明,当PBA和PEDA的质量比为1:1时,所得聚氨酯的固体物质质量分数达32.74%,并具有良好的附着力和贮存稳定性。

The ethanol and ester-soluble polyurethane for ink binder was synthesized from polyester glycol（PBA、PEDA） and self-made chain extenders gradually addition react with toluene-2,4-diisocyanate（TDI）.The chemical structure of the product was characterized with FTIR.The mass ratio of PBA to PEDA which affects polyurethane property was studied.The results reveal that when the mass ratio of PBA to PEDA is 1,the solid weight is 32.47%,and the polyurethane shows up better adhesion and stability.
