Description

具有提高的熔体强度的热塑性配制物
发明领域
本发明涉及一种具有热塑性基体和1-40重量％高分子量热塑性加工助剂的热塑性配制物，其具有大于100000g/mol的重均分子量。该配制物具有高熔体强度，但在常规熔融加工条件下仍然可加工。该配制物可用于熔体加工制品，包括挤出产品，如挤出片材、泡沫材料、共挤出型材、吹塑膜，以及其他典型地通过热加工操作形成的物品。
发明背景
热塑性塑料是高度可变的聚合物，它们易于熔融加工成许多不同形状，如型材、片材、棒材；模塑和吹塑成薄膜和物品；以及在许多其他热塑性基材上挤出或共挤出。
热塑性聚合物配制物的熔体强度是许多熔融加工操作成功的关键因素。对于泡沫材料，更高的熔体强度防止泡孔不受控膨胀，提供小而均匀的孔尺寸。更高的熔体强度还防止泡沫材料在冷却之前坍塌，并锁定在泡沫结构中。在其他熔融加工操作中，高熔体强度允许将热挤出固体或泡沫材料从定型或校准设备中拉过。当共挤出热塑性塑料时，高熔体强度为聚合物熔体提供整体性，从而形成没有间隙的连续材料。
增大聚合物配制物的熔体强度的一种途径是增加该聚合物的平均分子量。虽然该方法得到高熔体强度，但熔体黏度会迅速增加，以至于熔体太黏，无法在常规熔融加工设备中加工。还知道更高程度的长链支化和网络/交联结构的存在也能产生更高的熔体强度，这种长链支化和网络/交联结构可存在于分子量非常高的加工助剂中。长链支化可通过辐射或者通过改进聚合工艺来引入到聚合物中。
PVC工业上已经使用熔融加工助剂来增加PVC配制物的熔体强度，这些熔融加工助剂是高分子量相容聚合物(US 2009/0093560)。
在论文“Effect of High Molecular Weight Acrylic Copolymers on theViscoelastic Properties of Engineering Resins”(高分子量丙烯酸系共聚物对工程树脂黏弹性的影响)，Journal of Vinyl&Additive Technology(乙烯基与添加剂技术学报)，2006，第143-150页中，N.Mekhilef等测定了250万至490万道尔顿的丙烯酸系加工助剂对丙烯酸系和聚碳酸酯配制物的影响。本发明使用分子量高得多的丙烯酸系加工助剂，这允许更低的加工助剂用量。更低的加工助剂用量对用申请人的配制物制成的制品的机械性能如模量和硬度产生更少的影响。
需要一种高熔体强度热塑性配制物，其具有足够低的熔体黏度，从而能够在常规熔融加工条件下加工。
令人惊讶的是，现在发现可在热塑性基体中添加低含量的高分子量热塑性加工助剂，以显著增加热塑性配制物的熔体强度，而熔体黏度的增加微乎其微或没有增加——使得高熔体强度配制物能够在常规设备中，在常规条件下熔融加工。高分子量丙烯酸系加工助剂具有大于100000g/mol的分子量。加工助剂能够以低含量用于其中的热塑性配制物对用申请人的配制物制成的制品的机械性能如模量和硬度产生最小的影响。由于具有高多分散性的高分子量加工助剂的低用量和剪切稀化性质，常规加工条件下的黏度可受最小影响。
发明概述
本发明涉及一种高熔体强度热塑性配制物，其包含：
a)包含热塑性聚合物的热塑性基体；
b)1-40重量％的高分子量丙烯酸系加工助剂，

可用的抗冲改性剂包括与基体聚合物折射率匹配的嵌段共聚物、接枝共聚物和核/壳抗冲改性剂。在优选的实施方式中，抗冲改性剂包含至少50重量％的丙烯酸系单体单元。基于基体聚合物和所有添加剂的总层，抗冲改性剂的含量可为0-80重量％，优选5-45重量％，更优选10-30重量％。抗冲改性剂的含量可调节，以满足组合物终端用途的韧性要求。核/壳抗冲改性剂是多阶段依序制备的聚合物，其具有至少两层的核/壳颗粒结构。在一个实施方式中，核/壳抗冲改性剂具有软(弹性)核和硬壳(Tg大于20℃)。较佳的是，核/壳改性剂包含三层，其由硬核层、一个或多个中间弹性层和硬壳层组成。较佳的是，抗冲改性剂是核/壳结构，其中壳包含至少50重量％的甲基丙烯酸甲酯单体单元。在一个实施方式中，核/壳抗冲改性剂具有硬核(Tg大于30℃，更优选大于50℃)。在一个实施方式中，核/壳抗冲改性剂完全由丙烯酸系单体单元组成。
加工
热塑性基体聚合物、高分子量丙烯酸系加工助剂和任选的抗冲改性剂及其他添加剂在熔融状态下掺混。热塑性配制物的两种或更多种组分可先干掺混，然后熔融掺混。在一个实施方式中，高分子量丙烯酸系聚合物、热塑性基体聚合物和任选的抗冲改性剂熔融掺混在一起，并形成粒料。然后在熔融加工设备操作中与其他组分一起添加粒料，所述其他组分如染料、填料和发泡剂。
在一个实施方式中，热配混可通过用常规双螺杆挤出法形成热塑性配制物来完成。单螺杆挤出机和具有其他设计的挤出机也在本发明的构思范围之内。
在另一个实施方式中，高分子量加工助剂、基体聚合物和/或抗冲改性剂中的一种或多种的乳液可掺混成液体分散体，然后可通过例如喷雾干燥、凝固或冷冻干燥来干燥掺混物，形成粉末掺混物。然后，粉末掺混物可进一步与热塑性配制物的其他组分通过干掺混或熔融掺混来配混。粉末-粉末掺混也在构思范围之内。还构思了中间步骤，其中喷雾干燥的粉末通过挤出熔体方式配混成粒料，供进一步熔融配混。
可使用本发明的具有可控熔体黏度的高熔体强度热塑性配制物的常规熔融加工操作包括但不限于挤出、共挤出、注射成型、压缩成型、薄膜挤出和吹塑操作。本发明的高分子量、高多分散性配制物发生明显剪切稀化，因而它对高剪切黏度的影响将会最小。本发明的长链支化度更高的加工助剂能更有效地增加熔体强度。
用途：
本发明的热塑性配制物可用于熔融加工应用，这些应用可得益于高熔体强度而熔体黏度增加很少。这些应用包括但不限于泡沫材料、型材共挤出、热成型、熔融吹塑膜。基于所提供的描述和实施例，本领域普通技术人员能够容易地想到其他能得益于高熔体强度、低熔体黏度热塑性配制物的工艺。
在泡沫工艺中，在聚合物熔体中添加化学发泡剂或气体发泡剂，该熔体在离开挤出机时膨胀。高熔体强度配制物在发泡操作中提供了若干优点。高熔体强度对单个泡孔的膨胀提供控制，允许形成更均匀的孔尺寸和更小的孔尺寸。泡沫的出模膨胀也得到更好的控制。高熔体强度还有助于防止泡孔在形成后坍塌。此外，由于聚合物配混物的更高熔体强度，挤出泡沫更容易定型和/或压延，而不会使发泡制品变形。
在型材共挤出中，熔体强度更高的丙烯酸系聚合物在热塑性配制物中提供了更多的连续性，在热塑性层上很少造成或没有造成间隙或坑洼印记，并且出模膨胀增大，更好地匹配共挤出基材。
对于棒材、片材及其他制品，挤出热塑性塑料的更高熔体强度减小了它们离开模头时的下垂量，也减少了热塑性层在共挤出中的下垂。
熔体强度更高的热塑性配制物允许吹塑膜工艺中有更好的控制，确保形成没有缺陷的连续薄膜。
在本说明书中，已经以能够清楚、简明地撰写说明书的方式描述了各种实施方式，但应理解的是，其本意是各种实施方式可以在不背离本发明的情况下进行各种分合。例如，应理解的是，本文所述的所有优选特征都适用于本文所述发明的各个方面。
