Description

硅烷改性环氧大豆油-聚乳酸聚氨酯组合物及其制备方法
技术领域
本发明涉及一种硅烷改性环氧大豆油-聚乳酸聚氨酯组合物及其制备方法，属于聚氨酯改性技术领域。
背景技术
聚乳酸(PLA)是一种无毒，绿色天然可生物降解的材料。它不仅具有良好的化学惰性、易加工性，而且还具有良好的生物相容性，在高分子领域有广泛的用途。广泛应用于生物医学材料领域。
环氧大豆油是用大豆油经过氧化处理后制得的一种化工产品，常温下为浅黄色粘稠油状液体，是一种使用广泛的聚氯乙烯无毒增塑剂兼稳定剂，与PVC树脂相容性好，挥发性低、迁移性小。环氧大豆油具有优良的热稳定性和光稳定性，耐水性和耐油性亦佳，可赋予制品良好的机械强度、耐候性及电性能，且无毒性，是国际认可的用于食品包装材料的化学工艺助剂。
现有技术中，单组分聚氨酯胶黏剂产品仅采用常规的聚醚多元醇与异氰酸酯及其他组分进行反应，得到的产品气孔多，力学性能差，储存稳定性差，容易分层，此外，产品的气味大，对于环境不友好，且生物可降解性差。
发明内容
本发明要解决的技术问题是，克服现有技术中的不足，提供一种硅烷改性环氧大豆油-聚乳酸聚氨酯组合物，用其制备的聚氨酯产品储存稳定性好，生物相容性和降解性良好，具有优异的物理化学性能，原料来源广泛，成本低，节能环保；本发明同时提供了一种简单易行的聚氨酯的制备方法。
本发明所述的硅烷改性环氧大豆油-聚乳酸聚氨酯组合物，包括以下质量份数的原料：
Figure BDA0002346197330000011
聚醚多元醇和聚酯多元醇的用量不同时为零；
所述聚醚多元醇的官能度为2-8，数均分子量为1000-12000；
所述聚酯多元醇的官能度为2-8，数均分子量为1000-12000。
优选的，聚乳酸为20-100目。
所述扩链剂为乙二醇、丙二醇、三羟甲基丙烷、1,4-丁二醇、二乙醇胺或三乙醇胺中的一种或多种。
所述硅烷偶联剂为乙烯基三乙氧基硅烷、乙烯基三甲氧基硅烷或乙烯基三(β-甲氧乙氧基)硅烷中的一种或多种。
所述的硅烷改性环氧大豆油-聚乳酸聚氨酯的制备方法，包括以下步骤：
取聚醚多元醇和聚酯多元醇，倒入三口烧瓶中，氮气保护下，升温至100-150℃，脱水至水分小于0.02％，滴入环氧大豆油，进行反应，反应温度为100-150℃，反应时间为3-8h；降温至60-120℃，氮气保护下滴入甲苯二异氰酸酯和扩链剂，再加入聚乳酸反应，反应2-8h；再滴入硅烷偶联剂，在120-160℃下反应3-8h，得到所述的产品。
本发明中，将环氧大豆油滴入与聚醚多元醇或聚酯多元醇或聚醚多元醇和聚酯多元醇的混合物中，反应生成环氧油脂混醚。由于环氧大豆油有优良的耐水耐油性，使得制备得到的环氧油脂混醚兼具优良的耐水性耐油性。在环氧油脂混醚与甲苯二异氰酸酯、扩链剂中加入聚乳酸，聚乳酸参与聚氨酯的合成反应，聚乳酸中两端的羟基与甲苯二异氰酸酯上的异氰酸基团反应，聚乳酸中两端的羧基与扩链剂或者是环氧油脂混醚中的羟基反应，将聚乳酸引入到聚氨酯分子链中，增加聚氨酯产品的生物相容性、生物可降解性。此外，利用环氧大豆油制备得到的聚氨酯产品气孔小又少，力学性能好，储存稳定性好，储存12个月不分层。另外，产品的气味小，对于环境友好。
与现有技术相比，本发明具有以下有益效果：
(1)本发明所述的硅烷改性环氧大豆油-聚乳酸聚氨酯组合物的配方设计科学合理，用其制备的聚氨酯产品储存稳定性好，生物相容性和降解性良好，具有优异的物理化学性能，原料来源广泛，成本低，节能环保；
(2)本发明所述的聚氨酯的制备方法，简单易行，还可以适用于生产弹性体、涂料、CASE等，适用范围广，利于工业化生产。
