摘要： 本发明属于海洋防污涂层技术领域，提供了一种防污涂料及其使用方法和应用。本发明防污涂料中的聚天门冬氨酸酯是一种含有仲胺结构的异氰酸酯固化剂，其结构中含有的酯基及脂肪族特性可以增加涂层的耐磨性，与A组份中的含多异氰酸酯的预聚体结合可以赋予防污涂料良好的韧性和弹性，使所形成的涂层具有极好的抗冲耐磨性。A组分中的羟丙基硅油型异氰酸酯预聚体引入了聚二甲基硅氧烷结构，聚二甲基硅氧烷结构可以与聚脲硬段产生微相分离作用迁移至涂层的表面，降低涂层表面能从而降低污损生物与界面的粘附力，迁移至底部的脲基结构和多余异氰酸酯基团可以通过氢键和化学键合增加涂层的附着力，保障其耐清洗耐磨性。

摘要： Disclosed herein are methods for synthesizing oligomer mixtures with one or more moieties capable of forming a multi-hydrogen bonding dimer. The method comprises the steps of providing certain intermediate reaction products; adding a polyol component to the intermediate reaction product to yield an oligomer mixture comprising one or more multi-hydrogen bonding groups; and further reacting the mixture with certain isocyanate-reactive compounds to yield a multi-hydrogen bonding oligomer, wherein solvents comprise less than 50% of the total by weight of all reagents used in the synthesis of the multi-hydrogen bonding oligomer. Preferably, such methods involve no separation, distillation, or isolation of any intermediate product, and as such, they are particularly useful for a continuous or one-pot synthesis.
