Abstract

本发明涉及一种基于异佛尔酮二异氰酸酯(IPDI)、六亚甲基二异氰酸酯(HDI)和/或其异氰脲酸酯与胺,特别是异佛尔酮二胺(IPD)的新的聚脲类。

Description

基于IPDI、HDI、其异氰脲酸酯类与胺的新型聚脲类
                            技术领域
本发明涉及一种基于异佛尔酮二异氰酸酯(IPDI)、六亚甲基二异氰酸酯(HDI)和/或其异氰脲酸酯与胺，特别是异佛尔酮二胺(IPD)的新型聚脲类。
                            背景技术
聚脲类是众所周知的，可在下列技术领域作为粘合剂使用：木材和纸、发泡材料，以及作为色漆和涂料用的树脂(Houben-Weyl E20/2(1987)，pp.1721～1751；Houben-Weyl XIV/2(1963)，pp.165～171)。
                        发明内容
本发明的目的是发现一种在粉末涂料的标准固化温度150～220℃条件下保持为稳定固态形式同时不释放显著数量(≤2％)有机物质或水的新型聚脲类。
本发明的目的是一种基于异佛尔酮二异氰酸酯(IPDI)和/或六亚甲基二异氰酸酯(HDI)和/或其异氰脲酸酯与胺的聚脲类，其NCO/NH2比例等于0.9～1.1∶1，平均分子量至少为5000。
该新型聚脲类包含异佛尔酮二异氰酸酯(IPDI)、六亚甲基二异氰酸酯(HDI)与胺，特别是异佛尔酮二胺(IPD)，作为其起始化合物。IPDI和/或HDI既可以二异氰酸酯也可以异氰脲酸酯的形式使用。这里，这些异氰酸酯或者它们的异氰脲酸酯的混合物也是有利并适合的。
所有脂族、(环)脂族、环脂族和芳族二胺和/或多胺(C5～C18)，优选异佛尔酮二胺(IPD)，均可在本发明范围内使用。
一般而言，制成的聚脲类的NCO/NH2比例介于0.9～1.1∶1。在加入等摩尔数量，即NCO/NH2比例等于1∶1时，将获得具有最大交联度的固态和脆性聚合物，它仅当高于240℃时熔融并伴随分解，且不溶于溶剂。
本发明范围内优选的聚脲类是那些包含IPD与IPDI异氰脲酸酯和/或HDI异氰脲酸酯及其混合物的聚脲类。
本发明另一个目的是制造基于IPDI、HDI和胺，特别是IPD的聚脲类的方法，其中在诸如甲苯之类溶剂中使用胺，在搅拌下向其中加入异氰酸酯，需要的话也是以溶剂稀释后的。为实现完全转化，反应混合物在溶剂回流的条件下加热2～3h，然后冷却，分离(过滤)出生成的聚合物，然后在真空下在130～170℃干燥3～6h。
本发明聚脲类可用作油漆工业的原料，特别是制造挥发性漆、色漆和涂料。
                        具体实施方式
下面将通过实例更详细地说明本发明。
实施例
一般制造过程
70gIPD，以1000mL甲苯稀释后加入到备有搅拌器、滴液漏斗和加热罩的2L三颈烧瓶中。随后，当量(NH2∶NCO＝1∶1)数量的对应异氰酸酯或混合物以相同数量甲苯稀释后逐渐滴加到该胺溶液中。如此加毕后，反应混合物在回流下加热2h。冷却至室温后，滤出相应固体(聚脲)并在真空下干燥(在130～170℃3～6h)。
聚脲实施例(数据单位为重量份数)

PH-4     70     -     91     69

所有产物均为白色/无色、脆性固体，不溶于标准溶剂中，仅在高于240℃熔融，伴随出现分解。
当上面所描述的聚脲类被用于例如粉末涂料时，将产物研磨并过筛至≤100μm是有利的。
