| 摘 要： | 对某双组分聚氨酯胶黏剂中多元醇组分(A组分)在放置过程黏度降低的原因进行了分析。对于特定基础配方,其他原料不变,采用脂肪族聚醚多元醇(DL-400)配制的A组分黏度低且稳定性好,采用主链含苯环的特种聚醚多元醇(A-600)配制的A组分黏度高且黏度随存放时间的延长而降低,在2周左右才趋于稳定。对试验结果的分析认为,黏度不稳定与聚合物分子向填料粒子表面的吸附过程有关。

| Abstract: | The causes of the viscosity of polyol component( Part-A) in two-component polyurethane adhesive decreased in storage were analyzed. The tests showed that,for a certain basic formula,Part-A using aliphatic polyether DL-400 had lower viscosity and better stability than that of using a special polyether A-600 containing benzene rings in polymer backbone when other ingredients were unchanged. The viscosity of Part-A using A-600 reached stable after decreasing in two weeks. The test results revealed that the viscosity instability of Part-A should be related to the absorption process of polymer molecules to surface of filler particles. |
