| 摘 要： | 随着聚氨酯原材料价格的持续增长,尤其是甲苯二异氰酸酯(TDI)价格居高不下,且挥发性强、毒性大,研究采用二苯基甲烷二异氰酸酯(MDI)替代TDI,用水替代MOCA固化,制备了一种环保型聚氨酯防水涂料,以缓解目前国内聚氨酯防水涂料企业因原材料价格持续高涨和环保要求带来的发展压力.并探讨异氰酸酯含量、填料、聚醚类型、化学助剂等因素对该聚氨酯防水涂料物理力学性能的影响.

| Abstract: | With continuous growth of the price of polyurethane raw materials especially TDI that with high volatility and toxicity,a new environmental protection polyurethane waterproof paint was developed by replacing TDI with MDI and substituting MOCA with water so as to reduce the developmental pressure of polyurethane coating industry due to sustained high price of raw materials and demand of environmental protection. Furthermore,the effect of isocyanate content,filling, kind of polyether and chemical additives on the physical and mechanical properties of polyurethane waterproof coating were discussed. |
