Abstract
本发明涉及活性预聚合有机化合物的应用,它至少包含一个键能不大于397kJ/mol的易夺取的氢原子的和至少一个烯属双键的结构单元,在有或无自由基引发剂的情况下,通过热、高能辐射或热和高能辐射的方式进行交联。
Description
本发明涉及活性预聚合有机化合物在有或无自由基引发剂的情况下,通过热、高能辐射或热和高能辐射的方式进行交联的应用。
这种物质可通过高能辐射,优选为紫外光;或在室温下通过使用已知的过氧化物和共引发剂如重金属盐的混合物,以自由基的方式;或通过使用热自由基引发剂如过氧化物、偶氮类引发剂或C-C-不稳定化合物,以热的方式进行反应,即,进一步聚合或交联。上述引发反应的方法也可按照任何所需的组合方式使用,可以联合使用热生成的自由基与UV-生成的自由基;也可以反应到B-阶段,即,经部分反应被终止且以后能被再引发的部分反应状态。
这些活性预聚合物,可作为涂料粘结剂、涂料组合物用于制备紧密的或孔状的、增强的或非增强的模制成型料、压铸组合物、电绝缘组合物、可日光固化的路面划线涂料、密封剂和涂料组合物;或用作印刷油墨的粘接剂、无纺材质的粘结剂、粘合剂、预浸渍料坯等。
一般通过溶解在活性稀释剂单体如苯乙烯、α-甲基苯乙烯、乙烯基甲苯、邻苯二甲酸烯丙基酯、丙烯酸酯乙烯系化合物或类似物中而使用的,包含二氢二环戊二烯(dihgdrodicyclopentadiene)(DHCPD)结构单元的不饱和聚酯树脂是许多专利的主题。在例如粉末涂料也可为固体物质的情况下,由于马来酸和富马酸双键的难以满足的均聚能力,这些活性稀释剂的使用在已有技术看来是重要的。
DE3107450涉及以环戊二烯的齐聚物为末端基的不饱和聚酯能够以烯属不饱和单体的溶液形式用于制备模制品和涂料。然而,从该文件中并不能推导出这种聚酯在无活性稀释剂条件下的使用。
EP101585-A涉及通过在聚酯的双键上加成环戊二烯而改性的,然后溶解在乙烯基单体中的不饱和聚酯树脂。
EP118786-A描述了用二环戊二烯改性的,溶解在乙烯基或烯丙基单体中的不饱和聚酯树脂,它可在两步法过程中固化得到具有高温稳定性的模制品。
EP260688-A也涉及溶解在乙烯基单体中的聚酯树脂。
DE3230924-A描述了一种用于制备包含环戊二烯结构且溶解在乙烯基单体中的聚酯树脂的特殊方法。
EP585742-A涉及包含不饱和聚酯树脂和聚氨酯丙烯酸酯树脂的固体物质的混合物。这些混合物适合作为粉末涂料,它在熔化之后,可在UV引发剂的存在下,于UV光下交联。
EP 0684284A1描述了由聚醚酯树脂和二环戊二烯聚酯树脂组成的协效混合物,它能溶解在苯乙烯中,并在过氧化物催化剂存在下可固化。
DE-A-1570273描述了其端基带有,例如衍生自四氢-邻苯二酰亚氨基乙醇的5-或6-元酰亚胺环,且溶解在不饱和单体中的聚酯。
本发明提供了包含具有至少一个键能不大于397KJ/mol的易夺取的氢原子并具有至少一个烯属双键的结构单元的活性预聚合有机化合物,在有或无自由基引发剂的情况下,通过热、高能辐射或热和高能辐射的方式进行交联的应用。
中的结构或作经由异戊二烯醇(Ⅴa)的酯被引入预聚合物中的那些物质,其中n=1-20。
按照本发明使用的活性预聚合有机化合物,可以是基于α,β-烯属不饱和二羧酸的且向其中引入了至少一种具有结构式(Ⅰ)至(Ⅹ)的包含易夺取的氢原子的基团的不饱和聚酯树脂;或者是由基于α,β-烯属不饱和二羧酸的且缺少具有易夺取的氢原子的基团的不饱和聚酯树脂,和包含具有易夺取的氢原子的基团的预聚合有机化合物组成的混合物。
这些预聚合有机化合物,可以衍生自单官能醇、多官能醇、其烷氧化产品、聚醚多元醇、聚酯多元醇、聚四氢呋喃和/或聚己内酯,它在端基上包含有经由α,β-烯属不饱和二羧酸的酯而连接上的且具有易夺取的氢原子的结构单元。
特别优选使用的活性预聚合有机化合物,在室温下为液体;或根据DIN 53180,其软化范围小于130℃且在100℃下的粘度低于100000mPas,同时在粘度不大于10000mPas的某个温度下其粘度至少稳定24小时,而且它在加工过程中能熔化或受热。
按照本发明使用的活性预聚合物质,可以单独或与粘结剂和/或有机填料和/或无机填料结合使用,可作为涂料粘结剂、涂料组合物用于制造紧密的或孔状的、增强的或非增强的模制成型料、压铸组合物、电线圈用电绝缘组合物、电气工程中绝缘线圈线用的电缆瓷漆、可日光固化的路面划线涂料、密封剂和涂料组合物;或用作印刷油墨粘接料、用作粘合剂或用作由有机或无机物质制得的定向或无定向的、平面的或任何成形的纤维衬材料的粘结剂。
按照本发明使用的活性预聚合有机化合物,可与常规的自由基引发剂、C-C-不稳定物质和反应促进剂,与稳定剂以及其它与选自粘度调节剂、流动促进剂和增亮剂的添加剂结合在一起使用。
进而,按照本发明使用的活性预聚合有机化合物,在固化时可采用一种或多种选自用多官能异氰酸酯、氨基树脂和多官能环氧化物进行共交联的已知的固化机理。
按照本发明使用的活性预聚合有机化合物,包含具有至少一个键能不大于397KJ/mol的易夺取氢并具有至少一个烯属双键的结构单元。
键能数值已在文献中给出,且可得自例如,在Library ofCongress中的由Allyn和Bacon,Inc(位于美国Massachusetts州Newton的Simon & Schuster的一个分支机构)出版的Mrrison,Robert Thornton的有机化学(位于内封面的表:均裂键的离解能),按出版日期的图书编目为ISBN-205-08453-2(1987)。
这些反应体可存在于相同的分子中。然而,活性预聚合物质(有机化合物)也可包括,由仅包含易夺取的氢原子的预聚合物与仅包含烯键的预聚合物组成的混合物。在固化过程中,也可采用一种或多种已知的固化机理,例如用多官能异氰酸酯、氨基树脂如三聚氰胺-、尿素-或苯并三聚氰二胺-甲醛树脂,多官能环氧化物等进行共交联。其这种辅助采用的交联机理,也可导致互穿网络在涂层中的生成,这样通常可得到特定的所需性能,如特别是高耐化学性。
中的结构被引入,其中-R-为氧或具有一个或多个酯、酰胺、氨酯和/或酮基团的二价基团或为盐型键。
可作为易夺取的氢原子被引入按本发明的物质中的其它结构的例子,为选自异烷基、氨基异烷基、环异烷基、具有一个或多个杂原子的环异烷基、异烷基芳基的基团;或具有以下结构式的结构,其中
n=2或3,
R2为例如不多于8个碳原子的二价脂族或芳族基团,或为单键,
R3有时为取代的二价脂族、环脂族、杂环或芳族基团,或为单键,
R4为氢、例如1-8个碳原子的直链或支链烷基、卤代芳基或异戊基苯基,
R5为烷基、卤代烷基、卤代芳基或异戊基苯基,
按照本发明使用的活性预聚合有机化合物可以是线性的,也可以是单一或多支化度的,且具有,例如由结构式(Ⅹ)和(Ⅺ)所给出的结构,其中-R-为桥键基团或单键且D-为具有易夺取的氢原子的结构。在本文中,烯属双键可同时位于分子的基团-R-中和其它部位上,或存在于与包含D-的预聚合物质进行混合的不含D-的任何预聚合物质中。由结构式(Ⅺ)和(Ⅻ)所给出的结构仅作为例子用于说明原理。
特别容易得到的物质是其中-R-为酯基的那些,且可通过二环戊二烯(DCPD)加成到多官能的多羧酸上而得到,在该反应中,催化剂如三氟化硼合乙醚的使用对于高转化率来说可能是必需的。非常易得的加成物,是马来酸酐和水与DCPD进行加成所得到的具有结构式(ⅩⅢ)和(ⅩⅣ)的物质。
如果使用这些物质,可通过与对羧基反应活性的聚合物的反应容易得到按照本发明所使用的物质。这种聚合物的例子为单-和多官能羟基化合物、单-和多官能羟基化合物的羧酸酯、单-和多官能聚合的环氧化物、有羟基-官能的天然油和树脂、环氧化的天然油和树脂、单-和多官能聚异氰酸酯、和单-和多官能聚胺。
此外,可经由环状不饱和二羧酸与氨基羧酸或氨基醇的酰亚胺,引入包含烯丙基氢的基团。其例子示于结构式(ⅩⅥ)和(ⅩⅦ)。具有易夺取的氢原子和OH基团的其它物质,为桥亚甲基四氢苯二甲酸及其衍生物,如甲基桥亚甲基四氢苯二甲酸或具有结构式(ⅩⅥ)
的四氢苯二甲酰亚氨基醇类。
这些化合物通过与对OH反应活性物质进行反应而适合用于合成按本发明的物质。
此外,包含烯丙基氢的环二羧酸的衍生物,可通过含马来酸的聚酯与其它二烯如丁二烯或戊二烯进行Diels-Alder反应而得到。
按照本发明使用的一种重要物质类别,包括具有结构式(ⅩⅢ)和(ⅩⅣ)的物质的酯,以及异戊二烯醇的马来酸单酯和富马酸单酯与烷氧化的单-和多元醇的酯,其中每种酯在每个分子中可包括2-2000个氧化乙烯和/或氧化丙烯单元,其例子为乙氧化的或丙氧化的三羟甲基丙烷,乙氧化的或丙氧化的季戊四醇,乙氧化的或丙氧化的甘油,聚乙二醇单烷基醚,聚丙二醇单烷基醚、聚环氧乙烷、聚环氧丙烷、聚四氢呋喃和聚己内酯型的聚酯-和聚醚多元醇。通过引入长链的聚对苯二甲酸乙二醇酯单元或聚丁二烯二醇,该物质在固化后具有分子假塑性和改善的弹性。同样合适的有:由上述羟基化合物与具有易夺取的氢原子的醇,例如糠醇、四氢糠醇、1-烷基链烯醇的单酯得到的酯;或由具有结构式(ⅩⅥ)和(ⅩⅦ)的物质与二羧酸,例如马来酸、富马酸、衣康酸、柠康酸、邻苯二甲酸及其异构体得到的酯。
这种按本发明的物质,通过调节烷氧化剂的类型和烷氧化的程度,也有可能控制其最终产品的性能如硬度、亲水性和弹性。在本文中,多元醇有可能是仅部分酯化的,而残留羟基可以是游离的、被可能含有或不含有易夺取的氢原子的其它物质酯化或醚化、或与其它活性物质进行反应。适合这种目的的化合物的例子为异氰酸酯或环氧化物。其它重要的物质类别是含羟基的天然油,如蓖麻油。另一种重要物质包括,包含具有易夺取的氢原子的结构单元的、基于α,β-烯属不饱和羧酸如马来酸、富马酸、衣康酸和/或柠康酸的不饱和聚酯树脂。正如以上所提及的,以活性稀释剂单体如苯乙烯、α-甲基苯乙烯、乙烯基甲苯、邻苯二甲酸烯丙基酯、丙烯酸酯和乙烯系化合物或类似物的溶液形式使用的,包含DCPD结构单元的不饱和聚酯树脂是许多专利的主题。在例如粉末涂料,也可为固体物质的情况下,由于马来酸和富马酸双键的难以满足的均聚能力,这些活性稀释剂的使用在已有技术看来是重要的。
为本发明目的的不饱和聚酯树脂,是包括具有易夺取的氢原子的的结构单元的已知聚酯。按照本发明使用的聚酯,是通过已知的已有技术中的聚酯制备方法,一般是在升高的温度下,通过多官能羟基化合物与多官能酸和/或其酸酐的缩聚反应进行合成的。此外,从这种物质的酯出发并在升高的温度下,通过酯基转移作用而生成聚酯通常是有利的,这是由于在某些情况下,这种酯基转移作用比直接酯化能更加容易和更加迅速地进行。也可通过使用(部分或全部)多官能胺而得到具有酰胺结构的粘结剂。部分使用单官能的起始物质可以调节分子量。下文中所列的起始物质,应该被看作仅用于说明本发明的例子。
合适的起始物质的例子为:二-和多羧酸如己二酸、辛二酸、苯二甲酸异构体、四氢邻苯二甲酸、桥亚乙基四氢邻苯二甲酸、六氢邻苯二甲酸、富马酸、马来酸、衣康酸、柠康酸、偏苯三酸、均苯四酸,二-和多元醇如乙二醇、聚乙二醇、丙二醇、聚丙二醇、丁二醇异构体、己二醇、新戊二醇、三羟甲基丙烷、甘油、季戊四醇、双酚A、氢化双酚A,OH-多官能聚合物如OH基-改性聚丁二烯或带有羟基的聚氨酯预聚物和环氧树脂,多官能天然物质或其衍生物如亚麻油脂肪酸。另外重要的是烷氧化的OH-官能物质,其例子为上述多元醇的乙氧化或丙氧化产物。
根据DE-A-1570323,引入酰胺和酰亚胺结构也是已知的已有技术。这种聚酯酰胺或聚酯酰亚胺,能够在许多场合下比纯聚酯更好地满足某些特殊要求,例如在热稳定性方面。在本发明范围内,涉及特定要求,例如硬度、弹性、粘度和/或软化点的聚酯合成,是按照熟练人员已知的常规进行的。例如,熟练人员知道,通过多元醇或多羧酸的链长来改变固化的聚酯树脂的弹性。例如,使用己二醇或己二酸合成的聚酯树脂,比基于苯二甲酸和乙二醇的聚酯树脂更加柔软。还有,对熟练人员来说,通过另外使用能够在聚酯分子中产生支化作用的多官能物质,如偏苯三酸或三羟甲基丙烷来控制性能是已知的。在本文中,向聚酯中引入具有易夺取的氢原子的结构性组分例如通过另外使用带有易夺取的氢原子的可共缩合的起始物质而得以完成。这种易得到且不昂贵的起始物质,是马来酸酐和水与具有结构式(ⅩⅢ)和(ⅩⅣ)的DCPD的加成物,它可与其它化合物一起用于合成聚酯。
还有,也能在合成聚酯中使用具有结构式(ⅩⅤ)的二氢二环戊二烯醇,由此也可引入具有易夺取的氢原子的结构。
用于合成具有易夺取的氢原子的结构性组分聚酯的其它物质的例子,为1-甲基链烯醇、具有结构式(ⅩⅥ)的四氢邻苯二甲酰基氨基烷醇、具有结构式(ⅩⅦ)的桥亚甲基四氢邻苯二甲酰基氨基烷醇、异戊二烯醇、糠醛和四氢糠醛。
大多数不饱和聚酯是非常粘稠的或固态的树脂。本发明的一个特点是使用了具有结构式(Ⅺ)和(Ⅻ)的按本发明的物质,它不是常规的聚酯树脂甚至有时是沸点非常高的低粘度液体;结果,它们所代表的活性稀释剂特别适合本发明的体系,且没有已知的包含丙烯酸基或乙烯基不饱和物如苯乙烯或丙烯酸酯单体的活性稀释剂单体的缺点。这些物质带有两个或多个具有易夺取的氢原子的活性基团;或在由低级醇或二醇与具有结构式(ⅩⅢ)和(ⅩⅣ)的物质形成的单酯的情况下,包含有高摩尔浓度的这些活性基团。因此,它们是高活性交联剂,在许多情况下它们可单独使用,但最好与其它物质一起存在于常规的线性聚酯树脂或低支化度的聚酯树脂中。
从而,有可能对应用技术中重要的软化范围或粘度范围进行调节,而在加工和固化过程中又不产生过高的散发物。这样,具有相对高熔融粘度和高软化点的聚酯可用于本发明,通过加入这些物质可调节到所需要的低加工粘度。也可部分使用已知的聚酯。新颖的是:将该物质自身,特别是与由不饱和聚酯树脂和非聚酯的、相当于结构式(ⅩⅢ)和(ⅩⅣ)的多官能物质组成的本发明的活性混合物进行交联反应,而不必使用单体或聚合物型的活性稀释剂。
在加入能够在加热时产生自由基的物质之后,按照本发明使用的活性预聚合物质就能够进行热固化。已知的自由基引发剂的例子为过氧化物、偶氮化合物、叠氮化物和C-C不稳定物质。通过使用金属共引发剂,例如钴-、镁-、铁-、镍-或铅的化合物,可使固化明显加速,并使固化温度降低。
还有,在α-裂解型(NorrishⅠ型)或H-给体/受体型(NorrishⅡ型)UV引发剂的存在下,按本发明的聚合物是高UV感光性的。
按照本发明使用的,且由于它们分子带有H-受体基团因而具有增强的光敏性的物质也是可以生成的,例如通过具有羟基-官能的苯酮化合物如羟基二苯甲酮或双羟基二苯甲酮而引入其中的H-受体基团。
按照本发明使用的物质,可单独地或与其它粘结剂和/或有机和/或无机填料一起,作为涂料粘结料、涂料组合物用于制备紧密的或孔状的、增强的或非增强的模制成型料、压铸组合物、电绝缘组合物、可日光固化的路面划线涂料、密封剂和涂料组合物;或用作印刷油墨粘接料、粘合剂、用作由有机或无机物质制得的定向或无定向的、平面的或成形的纤维衬材料的粘结剂。
按本发明的物质一般是液体且可直接使用。如果它们在加工过程中粘度太高或为固态,可对它们进行加热,熔化或溶于溶剂中或以分散在水中的形式使用。
实施例1

4.00g 二月桂酸二丁基锡和
4.00g 对苯二酚。

实施例2

将烧瓶的内容物冷却至70℃,然后加入
1730.00g 三羟甲基丙烷和OH值为165的环氧乙烷的乙氧化产物,
4.00g 二月桂酸二丁基锡
然后在轻微的氮气流下,将混合物迅速加热至120℃。随后在六个小时的过程中,将温度逐渐升至190℃并通过蒸馏去除缩合反应产生的水,得到一种酸值为31的柔软树脂。

将溶液刮涂到钢板上,涂层厚度为80μm。在减压下,于40℃时经过三小时的时间,从薄膜中去除溶剂,得到不剥落的薄膜。首先,用中压汞灯以80mW/cm2的能级辐射薄膜240秒。在实施例1至3的情况下,得到了一种不剥落表层,其下仍有未干的组份;而对比例产物的粘性则未变。然后将钢板在烘箱中于180℃下烘烤30分钟。冷却之后,在实施例1至3的情况下,得到了坚硬的、具有良好挠曲强度的耐乙醇的薄膜;而对比例产物,即使在烘烤之后,其粘性实际上却没有降低。
