Abstract

本发明提供一种以聚对苯二甲酸丁二酯(PBT)为基质，能够均匀熔敷，而且具有高的熔敷强度的激光熔敷用PBT类树脂组合物、以及其成形品。激光熔敷用树脂组合物相对于聚对苯二甲酸丁二酯类树脂(均聚酯或者共聚酯)(A)100重量份，含有聚苯乙烯类热塑性弹性体或聚酯类热塑性弹性体等弹性体(B)1-50重量份、聚碳酸酯类树脂(C)5-100重量份、增塑剂(芳香族多元羧酸酯、丙烯酸类增塑剂等)(D)1-10重量份和玻璃纤维等填充剂或者补强剂(E)0-100重量份。如果由该树脂组合物调制成形品，则由上述成形品部位的不同产生的光线透过率的变化幅度小。因此，可以与对应材均匀地进行激光熔敷。

Description

激光熔敷用树脂组合物和成形品
技术领域
本发明涉及激光熔敷性高、成形加工性优异的聚对苯二甲酸丁二酯类树脂组合物、以及使用它的成形品。
背景技术
聚对苯二甲酸丁二酯(PBT)类树脂由于其耐热性、耐化学性、电特性、机械特性、以及成形加工性等各种特性优异，可用于多种用途。作为具体的用途，可以举例为各种汽车用电气安装部件(各种控制单元、各种传感器、点火线圈等)、连接器类、开关部件、继电器部件、线圈部件等。作为这些部件有时需要气密性，为了简单地制作这些部件，可利用粘合剂、加热板熔敷、超声波熔敷等接合方法。但是，在这些接合方法中，存在几个问题。例如如果使用粘合剂，则存在的问题是到粘合剂固化为止的工序时间的损失和对环境造成的负担。另外，就加热板熔敷和超声波熔敷而言，产品有可能因热或振动等遭到损坏。
另一方面，利用激光熔敷的接合方法中，产品不会因随着熔敷产生的热和振动遭到损坏，熔敷工序也非常简单。但是，当通过激光熔敷接合PBT类树脂时，由于激光的透过性低，会发生碳化等，因此被指出实际上不可能完成熔敷。在特开2001-26656号公报(专利文献1)中，公开了通过用熔敷加工使由具有特定范围熔点的聚酯类共聚物形成的成形品和其它的成形品一体化而制造成形体的方法。在该文献中，记载了均聚芳酸亚烷基酯树脂(聚对苯二甲酸丁二酯、聚对苯二甲酸乙二酯、聚萘二甲酸乙二酯)的激光熔敷强度较小。
在特开平10-245481号公报(专利文献2)中，公开了在由热塑性聚碳酸酯树脂和聚对苯二甲酸乙二酯等热塑性聚酯树脂构成的组合物中，按照1-10重量％的比例，混合在交联丙烯酸酯类弹性体的存在下使以甲基丙烯酸酯为主成分的单体进行接枝聚合得到的甲基丙烯酸酯类树脂(接枝树脂)而得到的热塑性树脂组合物。在该文献中，记载了在上述树脂组合物中，按照1.5/1～4/1(重量比)的比例使用双酚A型聚碳酸酯树脂和聚对苯二甲酸乙二酯树脂的例子。另外，作为上述组合物的热熔敷法，还记载了加热板熔敷法、振动熔敷法或者超声波熔敷法。但是，在该组合物中，要想提高熔敷强度，必须使用上述接枝树脂，同时如果使用该接枝树脂，则机械强度和耐热性容易下降。
另外，有时用以PBT类树脂为基质的成形品，相对于激光的透过率根据部位的不同而进行变化。因此，如果把这样的成形品与对应材(树脂成形品)进行激光熔敷，则有时使成形品和作为对应材的成形品不能在接触界面均匀而且牢固地熔敷。
专利文献1：特开2001-26656号公报(权利要求的范围)
专利文献2：特开平10-245481号公报(权利要求的范围)
发明内容
因此，本发明的目的在于提供以PBT类树脂为基质，同时均匀熔敷性高，可以均匀熔敷的激光熔敷用PBT类树脂组合物及其成形品。
本发明的另一目的在于提供激光熔敷性优异，而且能够获得高的熔敷强度的激光熔敷用PBT类树脂组合物、以及其成形品。
本发明人等为了实现上述课题而进行了专心研究，结果发现如果组合PBT类树脂、聚碳酸酯类树脂、弹性体和增塑剂进行注射模塑成形，则可以不依赖于成形品的部位，相对于激光的透过率高，而且均匀，使PBT类树脂组合物的成形品和对应材(树脂成形品)能在界面均匀而且牢固地进行激光熔敷，从而完成了本发明。
即，本发明的激光熔敷用树脂组合物(或者激光熔敷性树脂组合物)包含聚对苯二甲酸丁二酯类树脂(A)、选自聚苯乙烯类热塑性弹性体和聚酯类热塑性弹性体中的至少一种弹性体(B)、聚碳酸酯类树脂(C)和增塑剂(D)。作为基质树脂的聚对苯二甲酸丁二酯类树脂(A)也可以是聚对苯二甲酸丁二酯、或者用30摩尔％以下的共聚性单体改性的聚对苯二甲酸丁二酯类共聚物。弹性体的折射率在温度25℃下也可以为约1.52-1.59，增塑剂的折射率在温度25℃下也可以为约1.45-1.60。激光熔敷性树脂组合物还可以另外含有填充剂或者补强剂(E)。填充剂或者补强剂(E)没有特别的限制，例如，也可以是玻璃质填充剂或者补强剂(玻璃纤维、玻璃片、玻璃珠等)等。树脂组合物各成分的比例也可以是例如相对于聚对苯二甲酸丁二酯类树脂(A)100重量份，弹性体(B)为约1-50重量份，聚碳酸酯类树脂(C)为约5-100重量份，增塑剂(D)为约1-10重量份，填充剂或者补强剂(E)为约0-100重量份。另外，为了使光透过性稳定，也可以向树脂组合物中加入成核剂(F)。
由本发明的树脂组合物形成的成形品由于光线透过性(相对于激光的光线透过性)高，而且由成形品部位的不同产生的透过率的差小，所以适合于宽范围的激光熔敷。例如，在由注射模塑成形形成的纵80mm×横80mm×厚2mm的成形品中，照射800-1200mm波长的光线时，根据上述成形品部位的不同产生的光线透过率的变化幅度(光线透过率的最大值和最小值的差)为10％以下。
由本发明的树脂组合物形成的成形品与对应材的激光熔敷性优异。因此，本发明不仅包括由上述树脂组合物形成的成形品，而且还包括该成形品和对应材的树脂成形品通过激光熔敷进行接合形成的复合成形品。该复合成形品由上述树脂组合物形成，而且可以通过使位于激光透过侧的成形品和位于激光受光侧的对应材的树脂成形品接触，通过照射激光使上述成形品和上述树脂成形品进行接合来制造。
就本发明来说，由于将PBT类树脂、弹性体、聚碳酸酯类树脂和增塑剂组合使用，所以可以虽然以PBT类树脂为基质，但是透过率在整个成形品中都均匀，均匀熔敷性高，可以通过激光熔敷与对应材均匀熔敷。另外，激光熔敷性优异，可以获得高的熔敷强度。因此，可以获得以PBT类树脂为基质，激光熔敷性优异的组合物和成形品、和以高的熔敷强度进行接合的复合成形品。

在这些填充剂或者补强剂(E)之中，优选可以使激光透过的补强材料。这样的补强材料可以根据激光的波长进行选择。作为这样的补强材料，可以列举例如玻璃类或者玻璃质填充剂或者补强材料(玻璃纤维、玻璃片、玻璃珠等)等，特别优选玻璃纤维，例如具有高强度和刚性的玻璃纤维(切短纤维等)等。

本发明的PBT类树脂组合物也可以是粉粒状混合物或熔融混合物(颗粒等)。本发明的树脂组合物可以制造成形性高、机械强度和耐热性高的成形体或者成形品。特别是，用本发明的树脂组合物形成的成形品虽然由PBT类树脂组合物形成，但是光线透过性(特别是相对于激光的光线透过性)高，适合激光熔敷。例如，在以边浇口方式通过由宽2mm的铸口的注射模塑成形(例如，在实施例中记载的条件下的注射模塑成形)形成的成形品[长80mm×宽80mm×厚2mm]中，800-1200nm波长的光线透过率在厚度方向为约20％以上(例如，20-70％)，优选约25％以上(例如，25-60％)，更优选约30％以上(例如，30-50％)。而且，由本发明的树脂组合物形成的成形品光透过性根据成形品的部位(场所)产生的变化小，激光均匀透过。例如，在将本发明的树脂组合物进行注射模塑成形形成的上述成形品[长80mm×宽80mm×厚2mm]中，当沿厚度方向照射800-1200nm波长的光线(激光)时，由成形品部位的不同产生的光线透过率的变化幅度为约10％以下(0-10％)，优选约7％以下(0-7％)，更优选约5％以下(0-5％)，特别优选约3％以下(0-3％)，也可以是约2-6％。因此，可以宽范围地均匀而且牢固地进行激光熔敷，可以提高熔敷界面部分的气密性。另外，由于由激光产生的熔敷性高，所以可用于制造利用激光进行熔敷的成形体。
[成形体]
成形体可以用常用的方法制造由PBT类树脂(A)、弹性体(B)、聚碳酸酯类树脂(C)、增塑剂(D)、根据需要的填充剂或者补强材料(E)和/或成核剂(F)等构成的树脂组合物，所述常用的方法是例如(1)将各成分混合，用单轴或者双轴挤压机进行混合并挤压而调制成粒状，然后成形的方法，(2)先调制组成不同的颗粒(母料)，将该规定量颗粒混合(稀释)并用于成形，从而获得规定组成的成形品的方法，(3)直接向成形机中加入各成分中的1种或者2种以上的方法等。另外，颗粒也可以例如通过将除脆性成分(玻璃类补强材料等)之外的成分熔融混合后，再混合脆性成分(玻璃类补强材料)的方法调制。
成形体也可以通过将上述PBT类树脂组合物熔融混炼后，用挤压成形、注射模塑成形、模压成形、吹塑成形、真空成形、旋压成形、气体注射成形法等常用的方法成形，但是通常用注射模塑成形法进行成形。注射模塑成形的条件可以适当选择，例如，可以在约250-280℃下将PBT类树脂组合物熔融混炼，根据需要调制颗粒，利用注射模塑成形机，在气缸温度约250-280℃的条件下进行注射模塑成形。另外，模温度可以为60℃以下(例如，约40-60℃)，但是为了获得均匀的激光光线透过率的成形体，优选模温度为约65-90℃(例如，70-90℃)。
成形品的形状没有特别限制，但是由于通过激光熔敷将成形品与对应材(其它的树脂成形品)接合而使用，所以通常是至少具有接触面(平面等)的形状(例如板状)。另外，本发明的成形体由于相对于激光的透过性高，所以激光透过部位的成形品的厚度(激光透过方向的厚度)可以选择较宽的范围，也可以是例如约0.1-5mm，优选约0.1-4mm，更优选约0.1-3mm(例如0.5-3mm)。
作为激光光源，没有特别限制，例如，可以使用色素激光器、气体激光器(激元激光器、氩气激光器、氪激光器、氦氖激光器等)、固体激光器(YAG激光器等)、半导体激光器等。作为激光，通常使用脉冲激光。
上述成形品由于激光熔敷性优异，所以通常优选通过激光熔敷使其与对应材的树脂成形品进行熔敷，但是如果需要，也可以用其它的热熔敷法，例如振动熔敷法、超声波熔敷法、加热板熔敷法等使其与其它的树脂成形品熔敷。
本发明还公开了进行激光熔敷的复合成形品。该复合成形品是将由上述PBT类树脂组合物形成的成形品(第1成形品)和对应材的树脂成形品(第2成形品，被附体)通过激光熔敷进行接合一体化而成的。例如，可以通过使第1成形品和第2成形品接触(特别是至少使接合部分进行面接触)后，照射激光，使第1成形品和第2成形品的界面至少局部熔化而使接合面粘合，之后通过冷却将二种成形品进行接合、一体化，成为一个成形体。在这样的复合成形体中，如果使用本发明的成形体，则可通过熔敷获得高的接合强度，从而可以保持与用激光照射时不发生熔敷的非熔敷部件相同的高熔敷强度。因此，即使进行激光熔敷实际上也不会使接合强度下降，可以获得牢固接合的复合成形体。
作为构成上述对应材的树脂成形品的树脂，没有特别限制，可列举各种热塑性树脂，例如烯烃类树脂、乙烯基类树脂、苯乙烯类树脂、丙烯酸类树脂、聚酯类树脂、聚酰胺类树脂、聚碳酸酯类树脂等。在这些树脂之中，也可以由与构成上述PBT类树脂组合物的树脂相同种类或者相同类别的树脂(PBT类树脂、PET类树脂等聚酯类树脂(芳香族聚酯类树脂)，聚碳酸酯类树脂等)或者其组合物构成对应材。例如，也可以分别由本发明的PBT类树脂组合物形成第1成形体和第2成形体。
上述PBT类树脂组合物(或者第1成形体)只要不损害激光透过性(例如，相对于波长800-1200nm激光的透过性)，就可以包括着色剂(例如，特开2000-309694号公报和特开2001-71384号公报中记载的着色剂等)。作为着色剂，可列举相对于激光为非吸收性的着色剂(无机或者有机染颜料)，例如黄色染颜料(钙黄等无机颜料，联苯胺黄等有机颜料)、橙色染颜料(汉撒黄等)、红色颜料(红色颜料等无机颜料，色淀红等有机颜料)、蓝色颜料(钴蓝等无机颜料，铜酞花青蓝等有机颜料)、绿色颜料(铬绿等无机颜料，铜酞花青绿等有机颜料)、紫色染颜料等。这种着色剂可以单独使用，也可以多个着色剂组合使用而调整为所希望的色调。例如，可以利用减色混合(多种染颜料，例如黄色染颜料和紫色染颜料的组合，黄色染颜料和红色染颜料和蓝色染颜料的组合等)将树脂着色为没有色彩(灰色或黑色)。也可以通过使用这种着色剂不能目视识别第1成形体和第2成形体。第1成形体中着色剂的总使用量没有特别的限制，例如，可以相对于树脂100重量份为约0.01-10重量份(例如0.01-7重量份)，优选约0.01-5重量份。
被附体(或者对应材)也可以含有相对于激光的吸收剂或者着色剂。上述着色剂可以根据激光的波长进行选择，可列举无机颜料[碳黑(例如乙炔碳黑、灯黑、热裂法碳黑、炉黑、槽法碳黑、科琴黑等)等黑色颜料，红色氧化铁等红色颜料，钼橙等橙色颜料、氧化钛等白色颜料等]、有机颜料(黄色颜料、橙色颜料、红色颜料、蓝色颜料、绿色颜料、紫色颜料等)等。这些吸收剂可以单独或者二种以上组合使用。作为吸收剂，通常可以使用黑色颜料或者染料，特别是碳黑。碳黑的平均粒径通常为约10-1000nm，优选约10-100nm。着色剂的比例相对于被附体整体为约0.1-10重量％，优选约0.5-5重量％(例如0.5-3重量％)。
激光照射通常从第1成形体向第2成形体的方向进行，通过在包括吸收剂或者着色剂的第2成形体的界面上放热，使第1成形体和第2成形体进行熔敷。即，可以通过使位于激光透过侧的第1成形体(由本发明的树脂组合物形成的成形品)和位于激光受光侧的第2成形体(对应材的树脂成形品)接触，通过照射激光使上述第1成形体和上述第2成形体进行接合，获得复合成形品。而且，也可以根据需要使用透镜系，在第1成形品和第2成形品的界面上使激光聚光，从而在接触界面进行熔敷。

在实施例和比较例中，使用以下的PBT类树脂(A)、弹性体(B)、聚碳酸酯类树脂(C)、增塑剂(D)、填充剂或者补强剂(E)、成核剂(F)和着色剂。
PBT类树脂(A)
(A-1)间苯二甲酸二甲酯(DMI)改性PBT树脂
在对苯二甲酸和1，4-丁二醇的反应中，使用12.5摩尔％的DMI作为共聚成分来代替对苯二甲酸的一部分(12.5摩尔％)，从而调制改性聚对苯二甲酸丁二酯。
弹性体(B)
(B-1)含有环氧基的聚苯乙烯类热塑性弹性体ESBS[Daicel化学工业(株)制“EPOFRIEND AT504”]
(B-2)聚酯类热塑性弹性体[东洋纺(株)制“GP200”]
(B-3)聚苯乙烯类热塑性弹性体[Kuraray(株)制“Septon 4055”]
聚碳酸酯类树脂(C)
(C-1)聚碳酸酯树脂(帝人化成(株)制“PANLITE L-1225”)
增塑剂(D)
(D-1)芳香族多元羧酸酯[旭电化工业(株)制ADR CIZER-UL-100]
(D-2)丙烯酸类增塑剂[东亚合成(株)制ARUFON UP-1020]
(D-3)苯乙烯-丙烯酸类流动改性剂[东亚合成(株)制ARUFONXFM-910]
填充剂或者补强剂(E)
(E-1)玻璃纤维[日东洋纺织(株)制“CS3J-948S”，平均纤维直径φ11μm，平均纤维长400μm]
成核剂(F)
(F-1)氮化硼[川奇制铁(株)制FS-1]
(F-2)滑石[日本Talc(株)制Talc 3A]
着色剂
紫色染颜料[Clariant Japan制SANDOPLAST VIOLET RSB]
黄色染颜料[Clariant Japan制SANDOPLAST YELLOW 2G]
按照表1中所示的比例(重量比)，将各成分用两轴挤压机(日本制钢所制，30mmφ)在260℃进行混炼，从而制作颗粒。将得到的颗粒用注射模塑成形机((株)东芝制)，在气缸温度260℃和模温度80℃的条件下进行注射模塑成形，使试验片A(纵80mm×横80mm×厚2mm，边浇口，铸口宽2mm)成形。
另外，作为相对于上述试验片A的被熔敷体B，使用上述颗粒100重量份和黑色着色用炭黑(Win Tech Polymer(株)制，商品名“2020C”)5重量份进行注射模塑成形，制作壁厚2mm的箱形试验体B。该箱形试验体B是长80mm、宽40mm和高20mm的长方体状，上端面开口。另外，在下端面上，用激光熔敷进行密封，然后使用钻床形成用于施加内压的孔(φ10mm)。另外，试验体B作为基于激光的发热体发挥作用。
如图1中所示，在箱形试验体B(4)的开口端部分使试验片A(3)重叠而使其接触，使用激光熔敷机(Leister社制)，由激光振荡器的头部(1)开始调整激光(2)的焦点，在试验片A和箱形试验体B的接触面上按照线宽1.5mm使其聚光。然后，从试验片A(3)侧，在扫描速度10mm/秒的条件下照射波长940nm的激光进行熔敷，从而制作箱形试验体B的开口部分被试验片A(3)密封的盒状复合体。
(1)气密性(均匀熔敷性)
对于由激光熔敷获得的试验片A和试验体B的盒状复合体，在水中施加30秒内压0.02MPa，根据接合部分有无产生气泡来评价气密性。
(2)光线透过率
对于试验片A的各部位，使用分光光度计(日本分光(株)制“V570)”测量波长940nm下的光线透过率(％)，从而计算出光线透过率的最大值和最小值的差(变化幅度，％)。
实施例和比较例的结果示于表1中。
