Description

带槽的树脂成型品
本申请是申请日为2014年02月06日(最早优先权日为2013年02月12日)、申请号为CN201480008233.4、发明名称为“带槽的树脂成型品”的申请的分案申请。
技术领域
本发明涉及带槽的树脂成型品、使用该带槽的树脂成型品的复合成型品和它们的制造方法、以及上述带槽的树脂成型品的表面观察方法。
背景技术
近年来，以汽车、电气产品、工业设备等为代表的领域中，为了满足二氧化碳的排出量削减、制造成本的削减等的要求，将金属成型品的一部分替换为树脂成型品的趋势正在扩大。随之，将树脂成型品和金属成型品一体化而成的复合成型品广泛地得到普及。不仅如此，将由同种或异种的材料形成的成型品一体化而成的复合成型品也广泛地得到普及。
此外，由于大量采用填充有玻璃纤维等无机填充材料的树脂材料，该成型中的无机填充材料的取向大多成为问题，因此进行了用于观察无机填充剂的各种方法。
作为将一个成型品与其他成型品一体化的复合成型品的制造方法，提出了例如如下的方法。专利文献1中提出了如下方法：向一方的树脂中混入玻璃纤维等填充剂而成型，对粘接另一方的树脂的面实施化学试剂、等离子体、火焰等处理而去除厚度0.几μm～几10μm的树脂，然后使粘接前述另一方的树脂的面与前述另一方的树脂接触而进行填充、成型，从而使其粘接。此外，专利文献2中提出了如下方法：通过向一个树脂成型品的表面照射电磁辐射线而在该表面形成纳米结构，然后，使该表面与另一个树脂成型品接触而进行填充、成型，从而使其一体化。
此外，也进行通过切削、研磨表面、或用化学试剂等来实施处理而去除树脂成型品的表面的树脂，从而暴露出无机填充剂并进行观察、或用X射线CT来观察树脂成型品内部的无机填充剂。

具体实施方式
以下，对本发明的实施方式进行详细说明，但本发明并不受以下实施方式的任何限定，在本发明的目的范围内，可以适宜加以变更来实施。需要说明的是，对于重复说明的部分，有时适当地省略说明，但并非限定发明的主旨。
<带槽的树脂成型品10>
图1为本发明的带槽的树脂成型品10的概要放大截面示意图。带槽的树脂成型品10含有无机填充剂11，形成有暴露出该无机填充剂11的槽12。
[树脂]
对于树脂的种类，只要可以通过激光照射或化学处理等树脂去除方法而形成槽，就没有特别的限定。作为可以通过激光照射而形成槽的树脂，例如可以举出：聚苯硫醚(PPS)、液晶聚合物(LCP)、聚对苯二甲酸丁二醇酯(PBT)、聚缩醛(POM)等。
作为化学处理，可以举出：由酸或碱造成的分解处理、由溶剂造成的溶解处理等。在为非结晶性热塑性树脂的情况下，容易溶解于各种溶剂，但为结晶性树脂的情况下，选择使用两溶剂。作为能够通过添加酸或碱而形成槽的树脂，可以举出：聚对苯二甲酸丁二醇酯(PBT)、聚缩醛(POM)等。在化学处理中，进行限定于槽形成部的化学处理并去除化学处理的产物变得重要。
树脂可以为热塑性也可以为热固性。
[无机填充剂11]
对于无机填充剂11，在通过去除树脂成型品的树脂的一部分而形成槽时，只要暴露在槽中就没有特别限定。
作为无机填充剂11，可以举出：玻璃纤维、碳纤维、晶须纤维、玻璃鳞片、云母、滑石等。其中，通过激光的照射而形成槽时，除了容易透过激光、不易引起由纤维造成的激光遮蔽以外还廉价，因此优选无机填充剂11为玻璃纤维。为了防止无机填充剂11从复合成型品(图2的1)脱落，使无机填充剂11发挥抑制带槽的树脂成型品10和其他成型品(图2的20)的分离的锚固作用，理想的是无机填充剂从槽12的侧面12a突出，无机填充剂11的长度优选长度方向的长度比槽12的宽度方向的长度长。换言之，槽12的宽度方向的长度优选比无机填充剂11的长度方向的长度短。如果形状为纤维状，则优选平均纤维长度比槽12的宽度方向的长度长，如果形状为不规则、片状、颗粒状，则长径、优选为平均粒径比槽12的宽度方向的长度长是优选的。
本发明中，槽12中暴露出的无机填充剂11在有效地发挥抑制带槽的树脂成型品10和其他成型品20的破坏的锚固作用时，从可以适当地架设在例如根据激光照射的部位和非激光照射部位的差异而去除树脂的一部分来形成的凹凸的凸起13之间的方面出发，优选无机填充剂11的形状为纤维状。
对无机填充剂11的含量没有特别限定，相对于树脂100重量份，优选为5重量份以上且80重量份以下。若低于5重量份，则即使无机填充剂11暴露在槽12中，该无机填充剂11也可能无法充分发挥抑制带槽的树脂成型品10和其他成型品20的破坏的锚固作用。若超过80重量份，则带槽的树脂成型品10有可能不具有充分的强度。
[含有无机填充剂11的树脂材料的适当的市售品]
作为含有无机填充剂11的树脂材料的市售品，可以举出：加入玻璃纤维的PPS(产品名：DURAFIDE PPS 1140A7，Polyplastics Co.,Ltd.制造)；加入玻璃纤维/无机填料的PPS(产品名：DURAFIDE PPS 6165A7，Polyplastics Co.,Ltd.制造)；加入玻璃纤维的LCP(产品名：VECTRA LCP E130i，Polyplastics Co.,Ltd.制造)等。
[槽12]
树脂成型品10的表面形成有多个槽12。这些多个槽12中暴露出无机填充剂11。可以通过对树脂的一部分做去除来形成槽12，从槽12的侧面12a以突出的状态使无机填充剂11暴露出。多个槽12可以分别地形成，也可以通过一笔画的要领而一次形成包含多个凹凸的槽。
此外，对于本发明，在将带槽的树脂成型品10的具有槽12的面作为接触面并使之与其他成型品(图2的20)一体化来制造复合成型品(图2的1)时，在该复合成型品1中未暴露出无机填充剂11。本说明书中，即使在复合成型品1中未暴露出无机填充剂11的情况下，只要是在从复合成型品1去除其他成型品20的情况下，从槽12暴露出无机填充剂11，则成为“多个槽12中暴露出无机填充剂11”。
槽12的长度方向优选与无机填充剂11的长度方向不同。槽12的长度方向与无机填充剂11的长度方向相同时，有可能例如在根据激光照射的部位和非激光照射部位的差异而去除树脂的一部分来形成的凹凸的凸起13彼此之间无法适度地架设无机填充剂11，其结果，可能会使无机填充剂11容易从带槽的树脂成型品10脱落，无机填充剂11无法充分地发挥抑制带槽的树脂成型品10和其他成型品20破坏的锚固作用，无法正确地进行无机填充剂的观察。
就形成于树脂成型品10的表面的槽12而言，通过设置多个槽12而进一步提高锚固的效果。多个槽12可以用1个槽以相邻的形式折返形成，也可以由多个槽形成。
多个槽12可以是以等高线的形式排列设置两端连接起来的槽12，且也可以是形成无交叉的条纹状，槽12也可以是形成交叉的网格状。在将槽12形成为网格状时，优选形成为槽12的长度方向与无机填充剂的长度方向不同的斜网格状。此外，可以在将槽12形成为网格状时，成为图9的实施例3-3那样的菱形形状。
对槽12的长度并没有特别限定，在槽12短时，开口部的形状可以是四边形，也可以是圆形、椭圆形。为了得到锚固效果，优选槽12很长。
此外，可认为：本发明的带槽的树脂成型品10的用途是与其他成型品一起成为复合成型品的用途、以及观察无机填充剂的暴露状态的用途。在成为复合成型品时，为了充分发挥锚固的效果，相邻槽12的间隔W是槽的宽度的0.75倍以上且4倍以下，即如果槽的宽度为200μm，则优选相邻槽12的间隔W为150μm以上且800μm以下；更优选是，相邻槽12的间隔W是槽的宽度的1倍以上且2倍以下，即如果槽的宽度为200μm，则相邻槽12的间隔W为200μm以上且400μm以下。如果是间隔低于槽的宽度的0.75倍，即在槽的宽度为200μm时，则在间隔低于150μm时，无机填充剂11无法充分地发挥抑制带槽的树脂成型品10的破坏的锚固作用，在通过槽12与其他成型品20接合而形成复合成型品1时，有可能会在对复合成型品1施加外力时，由于有可能用很小的外力就破坏了带槽的树脂成型品10。如果是间隔为槽的宽度的4倍，即在槽的宽度为200μm时，则在间隔超过800μm时，无机填充剂11谈不上有充分地抑制其他成型品20破坏的锚固效果，在用槽12与其他成型品20接合而形成了复合成型品1时，在对复合成型品1施加外力时，有可能用很小就破坏了其他成型品20。
另一方面，在观察无机填充剂的暴露状态时，从残留于成型品表面的树脂成分变少，容易观察无机填充剂的方面出发，优选在无机填充剂不脱落的范围内，使相邻槽12的间隔W较短。具体而言，对于相邻槽12的间隔W，如果槽的形状为斜网格状，则间隔W优选为150μm以下，如果槽的形状为单一方向的直线状，则间隔W更优选为50μm以下。
此外，对于槽12的深度D，只要能观察无机填充剂11的程度即可，但在复合成型品中，优选深度D为槽的宽度方向的长度的1/2以上。在深度低于槽12的宽度方向的长度的1/2时，在通过槽12与其他成型品20接合而形成复合成型品1时，由于无法在槽12中暴露出的无机填充剂11与其他成型品20之间产生充分的锚固效果，因此，有可能无法牢固地密接带槽的树脂成型品10与其他成型品20。
此外，在要求牢固的接合强度的复合成型品中，优选相邻槽12的间隔为槽12的宽度的1倍以上且2倍以下。槽12的宽度过窄时，无机填充剂11无法充分发挥抑制其他成型品20破坏的锚固作用，有可能会在通过槽12与其他成型品20接合而形成了复合成型品1时，在对复合成型品1施加外力时，使其他成型品20遭到破坏。相邻槽12的间隔过窄时，无机填充剂11无法充分发挥抑制带槽的树脂成型品10破坏的锚固作用，有可能会在通过槽12与其他成型品20接合而形成了复合成型品1时，在对复合成型品1施加外力时，使带槽的树脂成型品10遭到破坏。这种槽间隔即使被局部设置在要求牢固的接合强度的部位，也是有效的。
<带槽的树脂成型品10的制造方法>
带槽的树脂成型品10是通过如下步骤而得到的：通过对含有无机填充剂11的树脂成型品进行激光的照射、化学处理等而部分去除树脂，从而形成暴露出无机填充剂11的多个槽来得到。
激光的照射是基于照射对象材料的种类、激光装置的输出等而设定的，但是对树脂照射适度的能量而不形成槽时，无法充分暴露出无机填充剂、或难以形成预期设定的宽度、深度的槽，因此优选分多次进行。
此外，无机填充剂会部分遮蔽激光的能量。因此，为了将树脂去除至深处，在想要多次进行激光的照射时，越往后则越需要赋予因激光接触到已经暴露出的无机填充剂而被吸收的能量部分的分量的高能量。因此，在多次重复地进行激光的照射时，优选包括使激光的照射量比前一次的照射量高的工序。
对无机填充剂的种类并没有特别限定，但从因激光的照射而造成的遮蔽效果少、容易去除树脂，容易适宜地架设在槽的两侧面之间的方面出发，优选无机填充剂为玻璃纤维。
此外，为了去除位于激光透光性低的无机填充剂的背面的树脂，优选从与成型品的表面通常垂直进行以外的其他方向进行激光的照射。
化学处理中，选择与树脂的特性相应的酸、碱、有机溶剂等而使用。在树脂因酸而分解的聚缩醛树脂成型品中，可以通过用酸来分解去除设置槽的位置而形成槽。在容易溶解于有机溶剂的非结晶性树脂成型品中，可以预先对成型品表面对设置槽的位置以外的部分进行掩蔽后，通过用有机溶剂进行溶解去除，从而形成槽。
<复合成型品1>
图2为本发明的复合成型品1的概要放大截面的示意图。复合成型品1中，在带槽的树脂成型品10的具有槽12的面上邻接有其他成型品20。对槽12的内部的其他成型品20的形态没有特别限定，但为了得到高锚固效果，其他成型品20优选在槽12的内部以包围无机填充剂11的方式配置。
[其他成型品20]
其他成型品20只要在未固化状态的情况下能够进入暴露出无机填充剂11的槽12中就没有特别限定，可以为热塑性树脂、固化性树脂(热固性树脂、光固化性树脂、辐射线固化性树脂等)、橡胶、粘接剂、金属等中的任意者。
<复合成型品1的制造方法>
复合成型品1并不限定于多次成型，可以通过超声波熔接、激光熔接、高频感应加热熔接等、树脂成型品之间的加热熔融而得到。
以往，在对包含异种材料的树脂成型品之间进行加热熔接时，需要对1次成型品的第一熔接预定面与2次成型品的第二熔接预定面的两者进行加热熔融。然而，在本说明书中记载的发明中，1次成型品和2次成型品即使为异种材料，也只要仅对第二熔接预定面进行加热熔融即可。根据本说明书中记载的发明，只要对预先形成槽12的第一熔接预定面压接其他树脂成型品20，并进行加热熔接即可，因此，可以减少树脂的溢出量，得到尺寸精度和接合强度两者优异的复合成型品1。
[多次成型]
图3为通过多次成型而得到复合成型品1时的概要说明图。首先，如图3的(1)所示，对1次树脂进行1次成型，制作带槽的树脂成型品预备体10’。接着，如图3的(2)所示，对预备体10’的表面的至少一部分，进行树脂的部分去除，形成槽12。由此，制作带槽的树脂成型品10。
接着，如图3的(3)所示，将带槽的树脂成型品10放入至模具(未图示)，在该模具的内部，将具有槽12的面作为接触面，密封2次树脂(构成其他成型品20的材料的未固化物)，固化该材料。通过经过上述工序，可以得到与由多次成型形成的固化性树脂的复合成型品1。此外，同样，通过采用加热熔融而成的热塑性树脂为2次树脂，而得到与由多次成型形成的热塑性树脂的复合成型品1。
如此，多次成型中，因为有将2次树脂密封至模具内部时的压力，所以容易将2次树脂填充至槽，在槽的内部，容易将2次树脂配置得包围无机填充剂。
在下述实施例中，是以带槽的成型品10具有槽11，其他成型品20不具有槽的形式进行说明的，但并不限定于此，例如，也可以是使其他成型品20也具有槽，在模具的一侧面放入带槽的成型品10，在另一侧面放入其他成型品20后，在带槽的成型品10与其他成型品20之间放入粘接剂组合物，该粘接剂组合物进入带槽的成型品10的槽11和其他成型品20的槽。无论粘接剂组合物的种类如何，即使是粘接剂组合物谈不上适合于带槽的成型品10与其他成型品20之间的层间粘接的情况下，也可以牢固地接合带槽的成型品10与其他成型品20。
[超声波熔接]
图4为通过超声波熔接而得到复合成型品1时的概要说明图。首先，如图4的(1)所示，使其他树脂成型品20的熔接预定面即第二熔接预定面201接近于带槽的树脂成型品10的熔接预定面即第一熔接预定面101。
第一熔接预定面101为具有槽12的面。此外，第二熔接预定面201优选与一般的超声波熔接相同而具有凸起201A。
接着，如图4的(2)所示，重叠第一熔接预定面101与第二熔接预定面201，形成使其上下压接的状态，在该状态下，通过超声波而在接合面产生纵向的振动，并通过振动的摩擦热而使它们熔接。通过经过上述工序，可以得到利用超声波熔接形成的复合成型品1。
超声波熔接可以使用例如SEIDENSHA ELECTRONICS CO.,LTD.制造的Ultrasonicwelder SONOPETΣ-1200超声波熔接机进行。此时，理想的是，设定沉降量是确定接合部品的状态而决定的最佳量。
[激光熔接]
图5为通过激光熔接而得到复合成型品1时的概要说明图。首先，在其他树脂成型品20的熔接预定面即第二熔接预定面201设置激光吸收部位202。激光吸收部位202是通过利用黑色马克笔(magic笔)涂布第二熔接预定面201等而得到的。需要说明的是，本实施例中，激光吸收部位202设置于第二熔接预定面201的大致整个面，但是只要设置于预先想要熔接的预定部位即可。
接着，如图5的(1)所示，使其他树脂成型品20的熔接预定面即第二熔接预定面201与带槽的树脂成型品10的熔接预定面即第一熔接预定面101相对。
第一熔接预定面101为具有多个槽12的面。对多个槽12的形状没有特别限定，槽12可以形成无交叉的条纹状，槽12也可以形成交叉的网格状。在将槽12形成网格状时，优选形成槽12的长度方向与无机填充剂的长度方向不同的斜网格状。此外，在将槽12形成网格状时，也可以为菱形形状。
第一熔接预定面101的槽12可以形成于第一熔接预定面101的整个面，但只要形成于与其他树脂成型品20熔接的部位即可。
接着，如图5的(2)所示，重叠第一熔接预定面101与第二熔接预定面201，使用夹具等形成使其上下压接的状态，进而，如图5的(3)所示，从与其他树脂成型品20的第二熔接预定面201相反的面朝向第二熔接预定面201照射激光。如此，通过激光的照射而熔解第二熔接预定面201附近的其他树脂成型品20，该熔化了的树脂因受到由上述压接形成的力而进入至槽12，与带槽的树脂成型品10熔接。通过经过上述工序，得到通过激光熔接形成的复合成型品1。
激光的照射可以是一个部位也可以是多个部位，但为多个部位时，优选以能够对抗由上述压接带来的力的程度，抑制照射的部位的数量，并且几乎均匀地照射激光。在对第二熔接预定面201的熔融树脂施加较大力而使之进入至带槽的树脂成型品10的槽12时，利用第二熔接预定面201的未熔融的部位来对抗力，因此，这是由于：照射的部位过多时，有可能对熔融树脂无法赋予适当的力。此外，由于在没有大致均匀地照射激光时，有可能在接合部位产生形变。
以往，激光熔接是在对同种材料形成的树脂成型品之间进行熔接时进行的。如果为同种材料形成的树脂成型品，则在2次成型品接受激光热量而进行放热时，也传递该热量至对面成型品，不仅2次成型品的熔接预定面发生了熔融，1次成型品的熔接预定面也发生熔融而相互地熔合。另一方面，这是由于：即使想要在同种材料形成的树脂成型品之间进行激光熔接，也限定于可以熔化2次成型品的熔接预定端面，而不会熔化1次成型品的熔接预定端面。
根据本发明，即使作为对象的树脂成型品彼此间为异种材料，如果2次成型品的熔接预定面被熔化，则也使其溶化的树脂进入至槽12，因此可以得到复合成型品1。此外，由于不会使1次成型品和2次成型品两者同时熔化，因此，尺寸稳定性优异。从此观点出发，本发明可以说是基于新颖的构思的发明。
[高频感应加热熔接]
图6为通过高频感应加热熔接而得到复合成型品1时的概要说明图。首先，如图6的(1)所示，在带槽的树脂成型品10的熔接预定面即第一熔接预定面101上载置放热体40，进一步载置其他树脂成型品20。此时，第一熔接预定面101与其他树脂成型品20的熔接预定面即第二熔接预定面201相对。需要说明的是，第一熔接预定面101为具有槽12的面。
放热体40具有通孔(未图示)，如果是被施加高频时放热的材质，则没有特别限定。
通孔的数量可以为1个也可以为多个，但通孔为多个时，优选以能够对抗由下述压接形成的力的程度来抑制通孔的数量。在对第二熔接预定面201的熔融树脂施加较大力而进入至带槽的树脂成型品10的槽12时，利用第二熔接预定面201的未熔融的部位来对抗力，因此，这是由于：通孔的数量过多时，有可能对熔融树脂无法赋予适当的力。
接着，如图6的(2)所示，重叠第一熔接预定面101与第二熔接预定面201，形成使其上下压接的状态，进而，如图6的(3)所示，从其他树脂成型品20的与第二熔接预定面201相反的面向第二熔接预定面201施加高频。如此，通过施加高频，而熔化第二熔接预定面201附近的其他树脂成型品20，该溶化了的树脂通过放热体40的通孔进入槽12，其他树脂成型品20与带槽的树脂成型品10熔接。通过经过上述工序，得到通过高频感应加热熔接形成的复合成型品1。
需要说明的是，在本说明书中，高频是指可以使放热体产生感应电流，由此使放热体放热的电磁波。此外，在概要说明图中，带槽的树脂成型品和其他树脂成型品是在平面之间进行压接的，但可以局部为凸形状，也可以在加热熔融后进行压接。
以往，高频感应加热熔接是在对同种材料形成的树脂成型品之间进行熔接时进行的。如果为同种材料形成的树脂成型品，则在2次成型品放热时，也传递该热量至对面成型品，不仅使2次成型品的熔接预定面熔化，也使1次成型品的熔接预定面熔化而使它们相互地熔合。另一方面，这是由于：即使想要在同种材料形成的树脂成型品之间进行激光熔接，也限定于可以熔化2次成型品的熔接预定端面，而不会熔化1次成型品的熔接预定端面。
根据本发明，即使作为对象的树脂成型品彼此间为异种材料，如果2次成型品的熔接预定面被熔化，则也使其熔化的树脂进入至槽12，因此可以得到复合成型品1。此外，由于不会使1次成型品和2次成型品两者同时熔化，因此，尺寸稳定性优异。从该观点出发，本发明可以说是基于新颖的构思的发明。

[带槽的树脂成型品的制造]
对在上述(注射成型的条件)所示的条件下将上述加入玻璃纤维的LCP(产品名：VECTRA LCP S135，Polyplastics Co.,Ltd.制造)进行注射成型而成的注射成型品，以使振荡波长为1.064μm、槽的宽度为200μm、相邻槽的间隔为200μm的方式，以斜网格状进行照射。激光的照射次数设为10次，扫描速度设为1000mm/s。由此，得到实施例6的带槽的树脂成型品。
另一方面，将上述加入玻璃纤维的LCP(产品名：VECTRA LCP S135，PolyplasticsCo.,Ltd.制造)自身作为比较例6的树脂成型品。
[复合成型品的制造]
对于实施例6和比较例6的每个带槽的树脂成型品，将具有槽的面作为第一熔接预定面，与VECTRA LCPS135(Polyplastics Co.,Ltd.制造)进行超声波熔接，制造实施例的复合成型品。超声波熔接是使用SEIDENSHA ELECTRONICS CO.,LTD.制造的Ultrasonicwelder SONOPETΣ-1200超声波熔接机，在设定凹陷量为0.8mm、超声波的频率为20kHz、振幅为60μm、空气压力为0.1MPa的条件下进行。
同样，对于比较例6的每个树脂成型品，在上述条件下与VECTRA LCPS135(Polyplastics Co.,Ltd.制造)进行超声波熔接，从而制作比较例6的复合成型品。
[破坏载荷的测定]
为了评价强度，对实施例和比较例的每个树脂成型品测定破坏载荷。破坏载荷的测定如下进行。使用Tensilon UTA-50kN(ORIENTEC Co.,Ltd.制造)作为测定装置，在十字头速度为1mm/分钟的条件下进行。将结果示于表12。
[表12]
