Abstract
本发明涉及通过添加抗氧化剂、苯并呋喃酮和/或空间受阻胺和肼或酰肼的混合物来稳定化链段化聚氨酯。
Description
技术领域
本发明涉及通过添加抗氧化剂、苯并呋喃酮类(benzofuranones)和/或空间受阻胺和肼或酰肼的混合物来稳定化链段化(segmented)聚氨酯。
背景技术
链段化聚氨酯广泛用作弹性纤维,如硫化橡胶的替代品。这类纤维熟知的名称是斯潘德克斯纤维(Spandex fibers)(H.G.Elias Makromoleküle,3rdedition1975,Hüthig and Wepf,Basel and Heidelberg)。斯潘德克斯纤维的主要问题是它们的热敏性、户外应用的气候性和在气体褪色条件下的变色性。
因此,现今用不同的稳定剂来稳定化斯潘德克斯纤维以改进它们的性能。通用的方法是用酚类抗氧剂来稳定化。进一步的改进可通过添加酚类抗氧剂和苯并呋喃酮型稳定剂来完成,例如描述于Research Disclosure1997 12,404;ISSN03744353中。
现已发现,当添加选自肼或酰肼类的进一步的稳定剂时,可完成就热稳定性、气候稳定性和气体褪色稳定性而言的进一步改进。
发明内容
本发明的一方面是包括链段化聚氨酯和以下组分的组合物:
a)一种或多种酚类抗氧剂,
b)苯并呋喃酮稳定剂和/或空间受阻胺稳定剂和
c)肼或酰肼稳定剂。
优选的链段化聚氨酯是斯潘德克斯纤维。在斯潘德克斯纤维中,聚合物链是链段化嵌段共聚物,其包括运动成更线性结构(更低熵值)的长的、无规盘绕的、液态的柔性链段结构。硬链段起“实际上交联”的作用,它们把所有的聚合物链连接在一起形成无限网络。这一网络阻止聚合物链的相互滑过和呈现永久变形或蠕变。当卸除拉力时,该线性、低熵值、柔性链段返回优选的无规盘绕,更高熵值的状态,从而使纤维恢复到它原来的形状和长度。以多步方法形成这一链段化嵌段共聚物。它被挤出成作为单纤维纱线的纤维或对于多数产品,挤出成形成单纱线后不久就聚结的多重细纤维(American Fiber ManufacturersAssociation Inc.)。
根据美国联邦贸易委员会,斯潘德克斯纤维定义为:一种制造的纤维,其中形成纤维的物质是包括至少85%的链段化聚氨酯的长链合成聚合物。
优选的酚类抗氧剂选自:2,6-二叔丁基-4-甲基苯酚、2-叔丁基-4,6-二甲苯酚、2,6-二叔丁基-4-乙基苯酚、2,6-二叔丁基-4-正丁基苯酚、2,6-二叔丁基-4-异丁基苯酚、2,6-二环戊基-4-甲基苯酚、2-(α-甲基环己基)-4,6-二甲苯酚、2,6-二-十八烷基-4-甲基苯酚、2,4,6-三环己基苯酚、2,6-二叔丁基-4-甲氧基甲基苯酚、线性或侧链支化的壬基苯酚,如2,6-二壬基-4-甲基苯酚、2,4-二甲基-6-(1′-甲基十一烷基-1′-基)苯酚、2,4-二甲基-6-(1′-甲基十七烷基-1′基)苯酚、2,4-二甲基-6-(1′-甲基十三烷基-1′-基)苯酚、2,4-二辛基硫代甲基-6-叔丁基苯酚、2,4-二辛基硫代甲基-6-甲基苯酚、2,4-二辛基硫代甲基-6-乙基苯酚、2,6-二-十二烷基硫代甲基-4-壬基苯酚、2,6-二叔丁基-4-甲氧基苯酚、2,5-二叔丁基氢醌、2,5-二叔丁基戊基氢醌、2,6-二苯基-4-十八烷氧基苯酚、2,6-二叔丁基氢醌、2,5-二叔丁基-4-羟基苯甲醚、3,5-二叔丁基-4-羟基苯甲醚、3,5-二叔丁基-4-羟苯基硬脂酸酯、双(3,5-二叔丁基-4-羟苯基)己二酸酯、α-生育酚、β-生育酚、γ-生育酚、δ-生育酚、2,2′-亚甲基双(6-叔丁基-4-甲基苯酚)、2,2′-亚甲基双(6-叔丁基-4-乙基苯酚)、2,2′-亚甲基双[4-甲基-6-(α-甲基环己基)苯酚]、2,2′-亚甲基双(4-甲基-6-环己基苯酚)、2,2′-亚甲基双(6-壬基-4-甲基苯酚)、2,2′-亚甲基双(4,6-二叔丁基苯酚)、2,2′-亚乙基双(4,6-二叔丁基苯酚)、2,2′-亚乙基双(6-叔丁基-4-异丁基苯酚)、2,2′-亚甲基双[6(α-甲苄基)-4-壬基苯酚]、2,2′-亚甲基双[6-(α,α-二甲苄基)-4-壬基苯酚]、4,4′-亚甲基双(2,6-二叔丁基苯酚)、4,4’-亚甲基双(6-叔丁基-2-甲基苯酚)、1,1-双(5-叔丁基-4-羟基-2-甲基苯基)丁烷、2,6-双(3-叔丁基-5-甲基-2-羟苄基)-4-甲基苯酚、1,1,3-三(5-叔丁基-4-羟基-2-甲基苯基)丁烷、1,1-双(5-叔丁基-4-羟基-2-甲基苯基)-3-正-十二烷基氢硫基丁烷、乙二醇双[3,3-双(3′-叔丁基-4′-羟苯基)丁酸酯]、双(3-叔丁基-4-羟基-5-甲基-苯基)二环戊二烯、双[2-(3′-叔丁基-2′-羟基-5′-甲苄基)-6-叔丁基-4-甲基苯基]对苯二甲酸酯、1,1-双(3,5-二甲基-2-羟苯基)丁烷、2,2-双(3,5-二叔丁基-4-羟苯基)丙烷、2,2-双(5-叔丁基-4-羟基-2-甲基苯基)-4-正-十二烷基氢硫基丁烷、1,1,5,5-四-(5-叔丁基-4-羟基-2-甲基苯基)戊烷、β-(3,5-二叔丁基-4-羟苯基)-丙酸与单或多元醇的酯类,如与甲醇、乙醇、正辛醇、异辛醇、十八醇、1,6-己二醇、1,9-壬二醇、乙二醇、1,2-丙二醇、新戊二醇、硫代二甘醇、二甘醇、三甘醇、季戊四醇、三(羟乙基)异氰脲酸酯、N,N′-双(羟乙基)草酰胺、3-硫代十一醇、3-硫代十五醇、三甲基己二醇、三羟甲基丙烷、4-羟甲基-1-磷杂-2,6,7-三氧杂二环[2.2.2]辛烷;β-(5-叔丁基-4-羟基-3-甲基苯基)丙酸与单或多元醇的酯类,如与甲醇、乙醇、正辛醇、异辛醇、十八醇、1,6-己二醇、1,9-壬二醇、乙二醇、1,2-丙二醇、新戊二醇、硫代二甘醇、二甘醇、三甘醇、季戊四醇、三(羟乙基)异氰脲酸酯、N,N′-双(羟乙基)草酰胺、3-硫代十一醇、3-硫代十五醇、三甲基己二醇、三羟甲基丙烷、4-羟甲基-1-磷杂-2,6,7-三氧杂二环[2.2.2]辛烷;3,9-双[2-{3-(3-叔丁基-4-羟基-5-甲基苯基)丙酰氧基)-1,1-二甲基乙基]-2,4,8,10-四氧杂螺[5.5]十一烷;β-(3,5-二环己基-4-羟苯基)丙酸与单或多元醇的酯类,如与甲醇、乙醇、辛醇、十八醇、1,6-己二醇、1,9-壬二醇、乙二醇、1,2-丙二醇、新戊二醇、硫代二甘醇、二甘醇、三甘醇、季戊四醇、三(羟乙基)异氰脲酸酯、N,N′-双(羟乙基)草酰胺、3-硫代十一醇、3-硫代十五醇、三甲基己二醇、三甲羟基丙烷、4-羟甲基-1-磷杂-2,6,7-三氧杂二环[2.2.2]辛烷;3,5-二叔丁基-4-羟苯基乙酸与单或多元醇的酯类,如与甲醇、乙醇、辛醇、十八醇、1,6-己二醇、1,9-壬二醇、乙二醇、1,2-丙二醇、新戊二醇、硫代二甘醇、二甘醇、三甘醇、季戊四醇、三(羟乙基)异氰脲酸酯、N,N′-双(羟乙基)草酰胺、3-硫代十一醇、3-硫代十五醇、三甲基己二醇、三甲羟基丙烷、4-羟甲基-1-磷杂-2,6,7-三氧杂二环[2.2.2]辛烷;β-(3,5-二叔丁基-4-羟苯基)丙酸的酰胺,如N,N′-双(3,5-二叔丁基-4-羟基苯基丙酰基)六亚甲基二酰胺、N,N′-双(3,5-二叔丁基-4-羟基苯基丙酰基)三亚甲基二酰胺、N,N′-双(3,5-二叔丁基-4-羟基苯基丙酰)酰肼、N,N′-双[2(3-[3,5-二叔丁基-4-羟苯基]丙酰氧基)乙基]草酰胺(NaugardXL-1,由Uniroyal提供)和它们的混合物。
