(A)聚合物树脂,和
(B)稳定化量的以下结构的亚磷酸酯
其中R1,R2,R3和R4独立地选自下组:烷基结构部分和以下结构的取代的环烷基结构部分

其它添加剂可以是例如增塑剂,环氧化的植物油如环氧化大豆油,润滑剂,乳化剂,颜料,荧光增白剂,阻燃剂,抗静电剂,发泡剂,和硫代增效剂如硫代二丙酸二月桂基酯或硫代二丙酸二硬脂基酯等。
除本发明的第一和第二亚磷酸酯外,另外的亚磷酸酯或亚膦酸酯,例如亚磷酸三苯酯,亚磷酸二苯基烷基酯,亚磷酸苯基二烷基酯,亚磷酸三(壬基苯基)酯,亚磷酸三月桂基酯,亚磷酸三(十八烷基)酯,二硬脂基季戊四醇二亚磷酸酯,亚磷酸三(2,4-二叔丁基苯基)酯,二异癸基季戊四醇二亚磷酸酯,三硬脂基山梨醇三亚磷酸酯,和4,4′-联苯二亚膦酸四(2,4-二叔丁基苯基)酯可以被用在本发明的某些实施方案中。已经发现,亚磷酸三(2,4-二叔丁基苯基)酯作为第三亚磷酸酯的使用在本发明的实践中是特别有利的,并且是优选的。
本文中描述的添加剂和稳定剂优选以有效改进组合物稳定性的量存在。当使用上述添加剂和稳定剂之一时,基于树脂的重量计量通常小于约5重量%,并且基于树脂的重量计量优选为至少约50ppm。
本发明的改进的稳定剂有利地帮助聚合物树脂组合物的稳定化,特别是在高温加工中,对抗熔融指数和/或颜色的变化,即使所述聚合物树脂可能经历很多挤出操作。这些稳定剂可以在由树脂组合物制造成型制品前的任何方便的阶段通过常规的技术容易地结合进所述树脂组合物中。例如,所述稳定剂可以与干燥粉末形式的树脂混合,或者所述稳定剂的悬浮体或乳液可以与聚合物的溶液、悬浮体或乳液混合。
含本发明的改进的稳定剂的组合物可以通过各种各样的方法制备,例如包括所述成分与配方中希望的任何其它材料的紧密掺混的那些方法。合适的程序包括溶液混合和熔体混合。因为在商业聚合物加工厂熔体混合设备的可获得性,熔体加工程序通常是优选的。在这样的熔体混合方法中使用的设备的实例包括同向旋转和反向旋转挤出机,单螺杆挤出机,盘式包装处理机(disc-pack processor)和各种其它类型的挤出设备。在某些情况下,所述混合的材料通过模口中的小的排出口离开所述挤出机,并且通过使得到的熔融树脂的条状物经过水浴而将所述条状物冷却。所述冷却的条状物可以被切成小颗粒,以便包装和进一步处理。
对用于获得颗粒形式的添加剂的方法的详细描述可见于例如美国专利号5,240,642和5,844,042。
所有所述成分可以首先被加入到加工系统中,或者另外地,某些添加剂可以被彼此预混合或者与一部分聚合物树脂预混合以制备稳定剂浓缩物。而且,采用至少一个放空口以允许熔体的放空(大气或真空)有时也是有利的。本领域普通技术人员将能够调节共混时间和温度以及组分添加位置和顺序,而不用过多的另外的试验。
尽管本发明的改进的稳定剂可以在将聚合物树脂制造成成型制品前通过常规的技术方便地结合进聚合物树脂中,也可以将它们通过局部涂布来施加到完成的制品上。制品可以包含本发明的稳定剂化合物和树脂,并且可以被制成例如照明灯罩,屋顶片材,电话罩,飞行器内部件,建筑内部件,计算机和商业机器外壳,汽车部件和家用器具。所述制品可以通过挤出、注射成型、旋转模塑、压缩和其他方法制备。这对于纤维应用可能是特别有用的,其中本发明的稳定剂被局部涂布在所述纤维上,例如通过熔融纺纱过程中的纺纱整理。
本发明的改进的稳定剂化合物还可以被用在热固性树脂组合物如聚氨酯、环氧树脂、蜜胺树脂和酚醛树脂中,并且可以被用于热固性/热塑性树脂共混物中。它们可以以上面对热塑性树脂组合物所给出的水平存在。
在没有进一步的详细说明的情况下,据信本领域技术人员利用本文的描述可以完全利用本发明。以下实施例被包括在本文中以给本领域技术人员提供关于实施所要求保护的发明的进一步指导。所提供的实施例仅是对本申请的教导有贡献的工作的代表。因此,这些实施例并不是意图以任何方式限制如所附权利要求书所定义的本发明。
实施例
在下面的表1中,以下亚磷酸酯被以它们的商品名提及:Ultranox626(Chemtura Corporat ion),Ultranox 641(Chemtura Corporation),Alkanox 240(Chemtura Corporation),Weston 619(ChemturaCorporation)和Doverphos S-9228(Dover Chemical Corporation)。
Ultranox 626是双(2,4-二叔丁基苯基)季戊四醇二亚磷酸酯。它的结构是:
Ultranox 641是2,4,6-三叔丁基苯基-2-丁基-2-乙基-1,3-丙二醇亚磷酸酯。它的结构是:
Alkanox 240是亚磷酸三(2,4-二叔丁基苯基)酯。它的结构是:
其中n=3.
Weston 619是二硬脂基季戊四醇二亚磷酸酯。它的结构为:
Doverphos S-9228是双(2,4-二枯基苯基)季戊四醇二亚磷酸酯。它的结构为:
在表1中:
实施例1-3和5和比较例1-3和5通过冷挤出制备。
实施例4和6和比较例4和6通过热挤出制备。
亚磷酸酯1是Ultranox 626.
亚磷酸酯2是Ultranox 641。
亚磷酸酯3是Alkanox 240。
亚磷酸酯4是Weston 619。
亚磷酸酯5是Doverphos S-9228。
冷挤出的颗粒
(表1中的实施例1)
将Ultranox 626(4.75kg),粉末状Ultranox 641(0.33kg,使用Fitzmil研磨以提供<60目的更小的颗粒大小)和DHT-4A(0.39kg)共混30-45分钟。
将所述均化的混合物通过一个Acrison计量体积的进料器进料到California Pellet Mill,其使用具有1/8直径模口孔的1厚模口和带直肋骨的辊。调节至所述颗粒磨的进料速率,以维持好的颗粒质量,并且送到20目筛分机以除去细粉,然后被循环回新鲜进料。所述方法在控制湿度和温度的环境中进行。
热挤出的颗粒
(表1中的实施例4)
将Ultranox 626(1.57kg),Ultranox 641(0.11kg)和DHT-4A(0.13kg)加入到行星式粉末混合器中。
将所述均化的混合物进料到Brabender实验室挤出机中,该挤出机具有长度为24D(800mm),直径为33mm的内腔(cochlea)和1∶4的压缩比,并且具有在所述内腔的8个不同区加热的能力。将所述混合物通过四个直径为2.5mm的孔挤出,所述内腔的旋转速率为320rpm,并且温度恒定在155。
将如此得到的挤出物(paghetti)在冷却到室温后切成小块,以得到具有约2-2.5mm的直径和8-12mm的长度的颗粒。
水解稳定性
(表1中的实施例3)
水解条件的控制
水解的测定依赖于能够产生具有均匀湿度和温度的恒定环境并且被精确控制的测试室。新墨西哥州Albuquerque的Thunder ScientificCorporation生产的系列2500试验台(benchtop)双压力湿度产生器是这样一种设备。水解测定值的重现性在大的尺度上取决于测试室的精度。参见以下说明:
2500型双压力湿度产生器(Model 2500 Two-Pressure HumidityGenerator)说明书
相对湿度精确性+/-0.5%
室温度精确性+/-0.6
室温度均匀性+/-0.1
重量增加
将1克被测试的样品在20mL闪烁管中称重,并且将所述管放在恒定温度/湿度的室中。以适当的时间间隔称量所述管,并且记录重量。重量增加表示为一定时间后样品初始重量的百分比。
酸值
水解的亚磷酸酯的酸含量通过测定中和已知量的样品所需要的碱的当量量来确定。将大约10克量的样品放在玻璃培替式皿中,并且将所述皿放在恒定温度/湿度的室中。在规则的时间间隔打开所述室,并且从所述培替式皿中取出1克样品用于酸值测定。
在与对照样比较的实施例1-6中举例说明本发明。实施例1的亚磷酸酯的水解稳定性(以其获得1重量%增加所花费的时间度量)优于对照样。即,如表1中所示,添加6%Ultranox 641对Ultranox 626的水解稳定性有显著影响,即82小时对48小时。令人惊异地,超过10重量%时Ultranox 641含量的增加(实施例2和3)导致Ultranox 626的水解稳定性与实施例1相比降低,尽管所述结果仍然好于采用对照样得到的结果。
众所周知,Alkanox 240(亚磷酸酯3)和Doverphos S-9228(亚磷酸酯5)具有优异的水解稳定性,并且添加这些亚磷酸酯至Ultranox 626导致更高性能的混合物(参见美国专利号6,680,351,7,157,511和7,176,252)。以上数据证明,在冷挤出情况下,或者甚至在热挤出情况下,添加6重量%的Alkanox 240或Doverphos S-9228不能与Ultranox641的出乎预料的和不能预见的性能相比。
考虑到在不偏离本发明原则的情况下可以做出的许多变化和修改,应该参考所附权利要求书来理解本发明的保护范围。
