Abstract
本发明涉及一种聚乙烯组合物,包括:a)含有可交联的含硅基团的聚乙烯(A);和b)母料,所述母料包括一种或多种添加剂;和含有C3‑C5α‑烯烃均聚物或共聚物(B)的载体。本发明还涉及通过对根据前述任一项权利要求所述的组合物在交联条件下进行处理可得到的交联的聚乙烯组合物。本发明还涉及以下用途:母料用于将添加剂加入含有可交联的含硅基团的聚乙烯中的用途,所述母料包括添加剂;和含有C3‑C5α‑烯烃均聚物或共聚物(B)的载体。C3‑C5α‑烯烃均聚物或共聚物(B)作为一种或多种添加剂的载体用于改善当聚乙烯组合物交联时硅烷醇缩合催化剂的性能的用途,所述聚乙烯组合物还包括含有可交联的含硅基团的聚乙烯。
Description
背景技术
添加剂,比如颜料、抗氧剂、硅烷醇缩合剂等,通常不会以其纯形式、而是以包含聚合物(所谓的载体)的所谓的母料的形式加入,其中所述添加剂以高浓度被包含。然后所述母料与所述母料的添加剂应当加入的聚合物进行复合。
采用催化剂的含有可交联的含硅基团的聚烯烃的交联是本领域众所周知的。在EP736065中特别描述了这种交联。然而,在将另外的添加剂(比如抗氧剂或颜料)添加到含有可交联的含硅基团的聚烯烃中的情况下,这种添加通常必须在交联之前进行。已经发现这样的添加剂可以降低硅烷醇缩合剂的交联性能,即需要更长的交联时间、更苛刻的交联条件(比如更高的温度和/或更高的湿度)和/或更高用量的催化剂。
因此,需要避免或至少减小添加剂对交联性能的负面影响。
发明内容
令人惊奇地发现,添加作为含有C3-C5α-烯烃均聚物或共聚物的母料的添加剂,能够改善交联性能。
因此,本发明提供一种聚乙烯组合物,其包括:
a)含有可交联的含硅基团的聚乙烯(A);和
b)母料,所述母料包括
-一种或多种添加剂;和
-含有C3-C5α-烯烃均聚物或共聚物(B)的载体。
令人惊奇地发现,通过在母料中使用C3-C5α-烯烃均聚物或共聚物,添加的母料形成了第二相。这使得损害母料以外的任何东西的添加剂(比如硅烷醇缩合催化剂)的使用成为可能。因此,虽然形成了第二相,但改善了硅烷醇缩合催化剂的交联性能。
此外,在母料中含有颜料的情况下,能够通过一相交联以及另一相着色而得到两相。
除非下文中有相反的表述,术语“母料”是指上述母料,其含有:
-一种或多种添加剂;和
-含有C3-C5α-烯烃均聚物或共聚物(B)的载体。
在本发明中,术语“载体”是指存在于母料中的聚合物的整体。
在组分(B)为共聚物的情况下,共聚单体的含量优选为基于组分(B)的总重量的至少2.0wt.%,更优选为至少5.0wt.%。
在组分(B)为共聚物的情况下,共聚单体的含量优选为基于组分(B)的总重量的不超过25wt.%,更优选为不超过20wt.%,最优选为不超过15wt.%。
组分(B)中的共聚单体优选选自C2-C8α-烯烃,更优选选自C2-C4α-烯烃,最优选所述共聚单体为乙烯。
应当理解,术语“共聚单体”意味着所述共聚单体不同于聚合物中的主要单体。就此而言,“主要单体”是指所述单体以基于组分(B)的总量超过50mol%的量存在。组分(B)中还可以存在两种或更多种共聚单体。通常组分(B)中存在不超过四种共聚单体,优选组分(B)中存在不超过两种共聚单体,最优选组分(B)中存在不超过一种共聚单体。

接枝可以在存在或不存在自由基引发剂下进行,但优选在自由基引发剂的存在下进行,所述自由基引发剂比如为有机过氧化物、有机过酸酯或有机氢过氧化物。
在接枝前添加到聚合物中的所述接枝剂的量优选为接枝剂所应用的聚合物的0.01到3.0重量%,更优选为0.03到1.5重量%。
或者,所述羧酸基团和/或羧酸酐基团还可通过共聚引入聚合物中。US 3 723 397中有特别描述。

优选地,根据本发明的聚乙烯组合物不含有任何除布朗斯台德酸之外的酸。
因此,根据本发明的聚乙烯组合物不含有为路易斯酸但同时不是布朗斯台德酸的化合物。

在一种优选的实施方式中,所述颜料由乳浊剂组成。优选地,所述乳浊剂选自二氧化钛和/或CaCO3,最优选地,所述乳浊剂为二氧化钛。
令人惊奇地发现,使用C3-C5α-烯烃均聚物或共聚物作为载体用于含有一种或多种颜料或一种或多种硅烷醇缩合催化剂的母料,会改善交联性能。因此,在其他条件(例如温度/压力)相同的情况下,能够采用相同量或更少量的硅烷醇缩合催化剂而获得更高的交联度。

具体实施方式
通过下文描述的实施例进一步解释本发明。
方法和实施例
熔体流动速率
熔体流动速率(MFR)根据ISO 1133测定并以g/10min表示。MFR是聚合物的流动性的指标,因而是加工性能的指标。熔体流动速率越高,聚合物的粘度越低。对于聚乙烯而言,MFR在190℃下测定。MFR可以 在不同载荷,比如2.16kg(MFR2)或21.6kg(MFR21)下进行测定。
密度
低密度聚乙烯(LDPE):密度根据ISO 1183-2进行测定。样品的制备根据ISO 1872-2表3Q(压塑法)进行。
低压法聚乙烯:聚合物的密度根据ISO 1183/1872-2B进行测定。
热延伸试验
将如下文“样条制备”项下的实验部分中制备的样条用于测定热延伸性能。根据ISO5275A由1.8+/-0.1mm厚的交联条制备得到三条哑铃状样品,该样品沿挤出方向取出。根据EN60811-2-1(热延伸试验)通过测量热形变来进行热延伸试验。
在哑铃上分别标记20mm的基准线。每个测试样品从其上端垂直固定在烘箱中,0.2MPa载荷系于每个测试样品的下端。在200℃的烘箱中保持15分钟后,测定预先标记的线之间的距离,计算热延伸百分率,即伸长率%。对于永久形变%而言,从测试样品上移除拉伸力(重量),然后在200℃恢复5分钟,然后使其在室温下冷却至环境温度。通过标记的线之间的距离计算永久形变%。报告三次测试的平均值。
采用X-射线荧光分析测定可水解的硅烷基的含量(mol-%)
将粒料样品压制成3mm厚的板(150℃、5巴的压力下2分钟,并冷却至室温)。通过波长色散XRF(Bruker公司提供的AXS S4Pioneer Sequential X-射线分光仪)分析硅原子的含量。所述粒料样品被压制成3mm厚的板(150℃、5巴的压力下2分钟,并冷却至室温)。
通常,在XRF方法中,样品经波长为0.01-10nm的电磁波辐射。然后存在于样品中的元素发射出具有离散能量的荧光X-射线辐射,所述离散能量对于每种元素是特征性的。通过测定发射出的能量的强度可以实现定量分析。所述定量方法通过含有已知浓度的目标元素的化合物进行校准,所述化合物可以在例如Brabender复合机中制备。
XRF结果示出Si的总含量(wt%),并计算为可交联的含硅基团(例如R1SiR2 qY3-q)的wt%。
熔点(Tm)
烯烃共聚物的熔融温度(Tm)根据ASTM D 3418进行测定。采用Mettler TA 820差示扫描量热(DSC)仪对3±0.5mg的样品测定其Tm。在-10到200℃之间以10℃/min冷却和加热扫描获得熔融曲线。熔融温度取作吸热和放热的峰值。
极性共聚单体和α-烯烃共聚单体的含量
极性共聚单体的共聚单体含量(wt.%)在以13C-NMR校准的基于傅里叶变换红外光谱(FTIR)测定法的已知方法中测定,如Haslam J,Willis HA,Squirrel DC在塑料鉴定和分析(Identification and analysis of plastics)(第二版,London lliffe books出版社;1972)中描述的那样。FTIR仪器为Perkin Elmer 2000,1次扫描,分辨率4cm-1。如本领域技术人员所知,将使用的共聚单体的峰与聚乙烯的峰对照(例如丙烯酸丁酯在3450cm-1的峰与聚乙烯在2020cm-1的峰相比较)。基于可聚合的单体的总摩尔数将wt.%通过计算转换为mol%。
另一种测定极性共聚单体以及α-烯烃共聚单体含量的方法是采用NMR-法,该方法与上述X-射线法和FTIR法得出同样的结果,即对于本发明的目的而言,所述两种结果将是相当的。
共聚单体的含量采用13C–NMR测定。样品溶于1,2,4-三氯苯/苯-d6(90/10w/w),在Bruker 400MHz分光仪上于130℃记录13C-NMR谱。(Ola27/32012)
