Description

一种有色聚丙烯纤维及其制备方法 技术领域
本发明涉及一种抗氧化性好的有色聚丙烯纤维及其制备方法。
背景技术
聚丙烯纤维由于具有轻量、快干等优点受到广泛的利用。然而聚丙烯在光和热的作用下会进行氧化分解，产生烷基自由基，而且这种反应会连续不断的进行下去。通过这种被称作自动氧化循环的连锁反应，聚丙烯自身氧化裂解，同时该裂解反应为发热反应，在自身发热的作用下聚丙烯会发生熔融、发烟甚至烧毁。
为了降低聚丙烯的氧化发热问题，现有技术中的主要措施是添加抗氧化剂。如专利CN02112743.3公开了一种可透明化聚丙烯组合物，为了提高聚丙烯的抗氧化性能在其中加入了酚类及亚膦酸酯类或硫酸类抗氧化剂。然而不同于透明聚丙烯，有色聚丙烯的抗氧化性更差，同时有色聚丙烯中的着色剂如炭黑等对抗氧剂有吸附作用，会影响抗氧剂在聚丙烯中的分布，削弱抗氧剂的作用。
发明内容
本发明的目的在于提供一种抗氧化性好的有色聚丙烯纤维。
本发明的技术解决方法：
一种有色聚丙烯纤维，该聚丙烯纤维中含有组分a受阻酚类抗氧剂以及组分b亚磷酸酯类抗氧剂和/或组分c受阻胺类抗氧剂，其中组分a占有色聚丙烯纤维的400～15000ppm；含有组分b时，组分b与组分a的重量比为0.8～6.0：1,优选0.8～4.0：1；含有组分c时，组分c占有色聚丙烯纤维的4000～50000ppm，优选4000～20000ppm。
当组分a占有色聚丙烯纤维的1100～15000ppm时，有色聚丙烯纤维的L值优选小于20。
当组分a占有色聚丙烯纤维的400ppm以上、小于1100ppm时，有色聚丙烯纤维的L值优选20～75。
所述组分a优选占有色聚丙烯纤维的500～8000ppm。
该有色聚丙烯纤维中优选同时含有组分a、组分b和组分c。
所述组分a受阻酚类抗氧剂类抗氧剂优选四[β-(3,5-二叔丁基-4-羟基苯基)丙酸]季戊四醇酯；β-(3,5-二叔丁基-4-羟基苯基)丙酸十八碳醇酯；1,3,5-三甲基-2,4,6-三(3,5-二叔丁基-4-羟基苄基)苯或1,3,5-三(4-叔丁基-3-羟基-2,6-二甲基苄基)-1,3,5-三嗪-2,4,6-(1H,3H,5H)-三酮中的至少一种。
所述组分b亚磷酸酯类抗氧剂优选聚(二丙二醇)苯基亚磷酸酯；双(2,6-二叔丁基-4-甲基苯基)季戊四醇二磷酸酯；三(2,4-二叔丁基苯基)苯基亚磷酸酯；双(2,4,6-三叔丁基苯基)季戊四醇二亚磷酸酯；四(2,4-二叔丁基酚)-4,4'-联苯二亚磷酸酯或3,9-双十八烷氧基-2,4,8,10-四氧-3,9-二磷螺环[5.5]十一烷中的至少一种。
所述组分c受阻胺类抗氧剂类抗氧剂优选聚{[6-[(1,1,3,3-四甲基丁基)氨基]]-1,3,5-三嗪-2,4-[(2,2,6,6,-四甲基-哌啶基)亚氨基]-1,6-己二撑[(2,2,6,6-四甲基-4-哌啶基)亚氨基]}；聚丁二酸(4-羟乙基-2,2,6,6-四甲基-1-哌啶乙醇)酯；NⅠ,NⅡ,NⅢ,NⅣ-四(2,4-二(N-1,2,2,6,6-五甲基-4-哌啶基)亚氨基-n)))-丁基氨基)-1,3,5-三嗪-6-基)-4,7-重氮癸烷-1,10-二胺；双(1-十一烷-2,2,6,6-四甲基哌啶-4-基)碳酸酯或1,3,5-三嗪-2,4,6-三胺-N-N”'-[1,2-乙烷二基双[[[4,6-双[丁基(1,2,2,6,6-五甲基-4-哌啶基)氨基]-1,3,5-三哑嗪-2-基] 亚氨基]3,1-丙烷二基]]-双[N'-N”-二丁基-N',N”-双(1,2,2,6,6-五甲基-4-哌啶基)]中的至少一种。
本发明还公开了一种有色聚丙烯纤维的制备方法，将聚丙烯与组分a受阻酚类抗氧剂以及组分b亚磷酸酯类抗氧剂和/或组分c受阻胺类抗氧剂混合均匀并挤出造粒得到有色聚丙烯混合物，然后将有色聚丙烯混合物进行熔融纺丝得到有色聚丙烯纤维，其中组分a占聚丙烯混合物的400～15000ppm,添加组分b时，组分b与组分a的重量比为0.8～6.0：1；添加组分c时，组分c占聚丙烯混合物的4000～50000ppm。
本发明所述的有色聚丙烯纤维具有优异的抗氧化性能，裂解发热少，应用广泛。
具体实施方式
聚丙烯本身的结构不稳定，容易被氧化，并且氧化过程伴随有发热现象，因此会影响使用聚丙烯纤维的制品的安全性。虽然添加抗氧剂可以提高聚丙烯的抗氧化性能，但是对于抗氧化性更差的含有着色剂的有色聚丙烯而言，由于着色剂对抗氧剂的吸附，会影响抗氧化剂的效果。而添加过多的抗氧剂又会降低聚丙烯制品的物理性能，且会导致有色聚丙烯制品容易黄变。
本发明提供的有色聚丙烯纤维不仅具有优良的抗氧化性能，纤维的物理性能如强度也较好，且不容易发生黄变。
本发明的有色聚丙烯纤维中含有组分a受阻酚类抗氧剂以及组分b亚磷酸酯类抗氧剂和/或组分c受阻胺类抗氧剂，组分a占有色聚丙烯纤维的400～15000ppm。当聚丙烯纤维含有组分b时，组分b与组分a的重量比为0.8～6.0：1；当聚丙烯纤维含有组分c时，组分c占有色聚丙烯纤维的4000～50000ppm。
在聚丙烯氧化分解的过程中会生成烷基自由基和过氧化自由基，其中烷基自由基会进一步氧化成过氧化自由基。而过氧化自由基不稳定，一部分过氧化自由基又会进一步生成氢过氧化物，加速聚丙烯的氧化分解。上述组分a受阻酚类抗氧剂可以捕捉过氧化自由基，组分b亚磷酸酯类抗氧剂可以捕捉氢过氧化物，组分c受阻胺类抗氧剂可以同时捕捉过氧化自由基和烷基自由基。
为了获得具有一定抗氧化性的有色聚丙烯纤维，纤维中组分a受阻酚类抗氧剂的含量必须在400ppm以上，否则组分a受阻酚类抗氧剂大部分被纤维中的着色剂吸附后将难以提高有色聚丙烯纤维的抗氧化性能，同时着色剂本身的抗氧化性能也较差，会导致有色聚丙烯纤维抗氧化性能的进一步恶化。而当有色聚丙烯纤维中组分a受阻酚类抗氧剂含量高于15000ppm时，不仅会增加有色聚丙烯纤维的制备成本，同时过量的组分a受阻酚类抗氧剂在空气中会被氧化生成醌类化合物，导致有色聚丙烯纤维发生黄变。
当组分a占有色聚丙烯纤维的1100～15000ppm时，有色聚丙烯纤维的L值小于20；当组分a占有色聚丙烯纤维的400ppm以上、小于1100ppm时，有色聚丙烯纤维的L值为20～75。
本发明的有色聚丙烯纤维中组分a受阻酚类抗氧剂含量优选为500～8000ppm。
组分b亚磷酸酯类抗氧剂除了具有上述捕捉氢过氧化物的作用外，还可以有效地抑制组分a受阻酚类抗氧剂在空气中的氧化，从而抑制聚丙烯的黄变。为了同时达到上述效果，有色聚丙烯纤维中组分b与组分a的重量比为0.8～6.0：1。当组分b与组分a的重量比低于0.8：1时，不能有效抑制组分a受阻酚类抗氧剂在空气的氧化，无法避免聚丙烯纤维的黄变，同时也不能有效的捕获氢过氧化物，聚丙烯的氧化分解加速严重。当组分b与组分a的重量比大于6.0：1时，相对于组分a受阻酚类抗氧剂会有较多的组分b亚磷酸酯类抗氧剂残留在有色聚丙烯纤维中，而由于已经没有可供捕捉的氢过氧化物，这部分组分b亚磷酸酯类抗氧剂起不到抗氧 化的作用，反而会增加有色聚丙烯纤维的制备成本，同时大量的组分b亚磷酸酯类抗氧剂会使聚丙烯纤维的强度下降。在含有组分b亚磷酸酯类抗氧剂时，本发明的有色聚丙烯纤维中组分b与组分a的重量比优选为0.8～4.0：1。
组分c受阻胺类抗氧剂的作用为捕捉烷基自由基及过氧化自由基。当有色聚丙烯纤维中组分c受阻胺类抗氧剂的含量低于4000ppm时，不能有效地捕捉烷基自由基及过氧化自由基，过多的烷基自由基会进一步氧化成过氧化自由基，而过氧化自由基又会生成大量的氢过氧化物，进一步加速聚丙烯的氧化，无法提高有色聚丙烯纤维的抗氧化性能。而当组分c受阻胺类抗氧剂的含量高于50000ppm时，有色聚丙烯纤维的强度下降，同时成本也会增加。在含有组分c受阻胺类抗氧剂时，本发明的有色聚丙烯纤维中组分c的含量优选4000～20000ppm。
本发明所述有色聚丙烯纤维中含有组分a受阻酚类抗氧剂以及组分b亚磷酸酯类抗氧剂和/或组分c受阻胺类抗氧剂，也即存在三种情况：一是含有组分a和组分b，二是含有组分a和组分c，三是含有组分a、组分b和组分c。其中优选第三种情况，即有色聚丙烯纤维中同时含有组分a受阻酚类抗氧剂、组分b亚磷酸酯类抗氧剂和组分c受阻胺类抗氧剂。

本发明所涉及的测试方法如下：
(1)耐氧化发热测试
首先将有色聚丙烯纤维制备成筒编物，并按照JIS L 0217 103法进行前处理。然后依据《聚丙烯纤维的酸化发热试验方法(加速法)》(日本化学纤维协会法)进 行测试并评价。当试验时间到达100小时时，自身并未发热，即判断该聚丙烯纤维的耐氧化发热性合格。否则，判定为不合格。
(2)纤维的黄变值测试
在密闭容器中放入NOx气体发生剂(85％磷酸及2％的亚硝酸水溶液)，然后将试样及蓝色标准染色布置于容器内，当蓝色标准染色布颜色褪为标准灰度板3号时，更换蓝色标准染色布，当颜色再次达到标准灰度板3号时，将试样取出，并清洗2次，晾干。通过Datacolor 650分光光度仪对黄变值进行测定。
(3)纤维的强度测试
通过强伸度测试仪进行测试。测试速度为200mm/min,两夹具之间的距离是200mm。
(4)纤维的抗氧化发热性(简易法/wt％)
取纤维样品，称取重量为W1，用差示扫描量热仪，在气体氛围为压空、气体流量为60±0.05ml条件下，从25℃开始以30℃/min的速度升温至160℃，保持22小时，通过分析得出重量减少率，重量减少率在10wt％以下的话，科肯法判断为合格。重量减少率越低，表明抗氧化性越好。

通过Datacolor 650分光光度仪对染色后的筒编物进行L值测定。
