优选的,所述烷烃型二异氰酸酯为六亚甲基二异氰酸酯(HDI)。所述二异氰酸酯为烷烃型二异氰酸酯时,所述合成方法包括如下步骤:将聚己内酯与一部分二异氰酸酯混合,80-100℃搅拌反应后,降至20-60℃加入具有增塑作用的小分子醇,60-110℃搅拌反应,继续加入剩余的二异氰酸酯,100℃搅拌至溶液澄清、无醇蒸汽,无气泡后,静置,即得。
进一步,所述聚己内酯的OH摩尔数:两次加入二异氰酸酯的NCO摩尔数和:小分子醇的OH摩尔数为3:9:1。优选的,第一次加入的二异氰酸酯的NCO摩尔数:聚己内酯的OH摩尔数为2:1。
优选的,所述具有增塑作用的小分子醇为异辛醇或正辛醇。
本发明具有的优点和积极效果是:本发明以聚己内酯为基体,将具有增塑作用的小分子醇作为增塑剂,通过二异氰酸酯作为交联剂,将增塑剂与聚己内酯之间进行接枝,有效提高聚己内酯的塑化刚性;形成既具柔韧性能、又具塑化刚性材料。
