(2)PU树脂的制备:
以DMF为溶剂,加入步骤(1)制备的聚酯多元醇与扩链剂搅拌30分钟后,加入六甲基二异氰酸酯升温至80℃,反应至粘度为24万时出料,即得PU树脂。
步骤(1)中葵二酸、壬二酸、乙二醇、1,4-丁二醇的摩尔比为1:1:1:1;
步骤(2)中聚酯多元醇、扩链剂、六甲基二异氰酸酯的质量比为12:2.5:1.2,所述扩链剂选自式A、式B、式C所示结构的邻苯二甲酸二乙二醇酯中的一种或几种,式A、式B、式C所示结构如下:
其中扩链剂优选式A、式B、式C以质量比1:1:0.5的组合。

将葵二酸、壬二酸、乙二醇、1,4-丁二醇混匀,加入催化量的钛酸四异丙酯,并升温至210-220℃,反应12小时得到聚酯多元醇;
(2)PU树脂的制备:
以DMF为溶剂,加入步骤(1)制备的聚酯多元醇与扩链剂搅拌30分钟后,加入六甲基二异氰酸酯升温至80℃,反应至粘度为24万时出料,即得PU树脂。
步骤(1)中葵二酸、壬二酸、乙二醇、1,4-丁二醇的摩尔比为1:1:1:1;
步骤(2)中聚酯多元醇、扩链剂、六甲基二异氰酸酯的质量比为12:2.5:1.2,所述扩链剂选自式A、式B、式C所示结构的邻苯二甲酸二乙二醇酯中的一种或几种,式A、式B、式C所示结构如下:
其中扩链剂优选式A、式B、式C以质量比1:1:0.5的组合。
本发明的另一实施方案提供一种聚氨酯合成革的制备方法,其特征在于包括如下步骤:
将本发明上述PU树脂与炭黑、DMF、消泡剂、滑石粉,混合搅拌均匀得料浆,并将料浆涂覆于基布上,并于25℃下至于20%DMF水溶液中浸泡2分钟,再进行水洗,水洗后的产品至于100℃烘箱中干燥即得聚氨酯合成革。
