| 摘 要： | 通过熔融缩聚法用二聚酸和异弗尔酮二胺(IPDA)等单体合成了一系列油墨用聚酰胺树脂,力学性能测试和差示扫描量热法(DSC)显示,IPDA制备的聚酰胺具有较高的邵氏硬度和剪切强度,但熔点(Tm)和玻璃化转变温度(Tg)有不同程度的降低.随着共聚二元胺单体中IPDA-乙二胺(EDA)比例的升高,聚酰胺树脂醇溶液的冻点逐渐降低,而软化点则先降低后升高.IPDA和二聚酸制备的聚酰胺(1009I)的软化点为103℃,其加%固含量正丙醇溶液在25℃的黏度208 mPa·s,玻璃化转变温度为44.2℃,邵氏硬度79,拉伸剪切强度14.64 MPa,溶解度参数17.87×10-3(J·m-3)2/1,能够溶于正丙醇、四氢呋喃和乙酸正丁酯,但IPDA不能提高聚酰胺树脂在乙醇中的溶解性.其20%正丙醇溶液的冻点达到-35℃,具有良好的抗冻性.

| Abstract: | A series of polyamide resins used for printing inks were synthesized by condensation polymerization of dimeric acid with isophorone diamine (IPDA) and other monomers. Results of differential scanning calorimetry (DSC) showed that polyamides prepared from IPDA have higher Shore hardness and shearing strength but lower melting point (Tm) and glass transition temperature (Tg). With the increase of IPDA:ethyl diamine (EDA) ratio,gel point of the alcoholic solution of polyamide decreased,while softening point de... |
