能着色、适合用于激光焊接领域的热塑性聚合物组合物以及由它制造激光焊接制品的方法。

Description

激光可焊热塑性聚合物组合物以及激光焊接方法
技术领域
本发明涉及能着色、适合用于激光焊接领域的热塑性聚合物组合物。本发明还涉及激光焊接含热塑性聚合物组合物的物体的方法。
背景技术
常常要求生产可机械地装配成更复杂零件的模塑塑料零件。传统上，塑料零件的装配一向通过将它们胶粘或螺栓连接或者使用搭扣配合连接件而实现的。这些方法存在着它们给装配过程增加复杂额外步骤的缺点。搭扣配合连接件常常不是气密且液密的并且要求复杂的设计。较新的技术是振动和超声焊接，但这些也可能要求复杂的零件设计和焊接设备。另外，加工造成的摩擦可能产生可能污染零件内部的粉尘。在涉及敏感电气或电子元件时这是突出问题。
较新研发的技术是激光焊接。在此种方法中，两个待连接的聚合物物体对所使用的激光波长具有不同的透光水平。一个物体对激光的波长来说是至少部分透明的(并被称作“相对透明”物体)，但第二零件(part)吸收相当一部分的入射辐射(并被称作“相对不透明”物体)。物体中的每一个呈现接触表面(faying surface)，而相对透明物体呈现与其接触表面相对的撞击表面(impinging surface)。使接触表面互相接触，于是形成接合(juncture)。激光束射向相对透明物体的撞击表面，以便它穿过第一物体并照射第二物体的接触表面，从而导致第一和第二物体在接触表面的接合处被焊接起来。通常参见美国专利5,893,959，在此收作参考。该方法可以是非常洁净、简单和快速的并提供非常牢固、易于复制的焊接和相当大的设计灵活性。
激光焊接的缺点是，相对不透明的物体必须包含吸收该激光波长光的材料。该激光吸收材料一般是颜料如炭黑或黑色染料如苯胺黑。这些材料的存在通常使相对不透明的物体变黑，即便当也存在其它颜色的着色剂时。然而，常常希望激光焊接制品的相对不透明零件具有天然颜色或着成某种颜色，包括白色，而不是黑色。于是，获得一种聚合物组合物，它能以其天然颜色或某种非黑的颜色使用，以形成用于激光焊接方法的相对不透明物体，则将是可心的。
美国专利申请公开号2003/0130381公开一种热塑性模塑组合物，它包含激光透明热塑性材料和一或多种选择的IR吸收化合物，其中该组合物含有小于0.1wt％炭黑。
发明概述
扼要地说，按照本发明一个方面，提供一种聚合物组合物，它包含：
(a)约17-约99.5wt％的热塑性聚合物；
(b)约0.003-约0.05wt％的炭黑；
(c)约0.4-约10wt％的选自二氧化钛、硫化锌和氧化锌之一或多种的无机物；
(d)0-约70wt％的增强剂和/或无机填料；
(e)0-约70wt％的添加剂；和
(f)0-约3wt％的一种或多种着色剂，
其中上述重量百分数以组合物的总重量为基准计。
按照本发明另一个方面，提供一种利用激光辐射将第一聚合物物体焊接到第二聚合物物体上的方法，其中所述第一聚合物物体对于所述激光辐射相对透明，而所述第二物体对所述激光辐射相对不透明，所述第一和所述第二物体每一个呈现接触表面，所述第一物体呈现与其所述接触表面相对的撞击表面，所述方法包含以下步骤：(1)使所述第一和第二物体的接触表面物理地接触，以便在二者之间形成接合以及(2)以所述激光辐射照射所述第一和第二物体，以便所述激光辐射撞击该撞击表面，穿过所述第一物体并照射所述第二物体的所述接触表面，从而导致所述第一和第二物体在接触表面的接合处被焊接，其中所述第二聚合物物体由热塑性聚合物组合物构成，它包含：
(a)约17-约99.5wt％的热塑性聚合物；

实施例
样品制备
实施例和对比例中使用的组合物由表1和2所示成分在单螺杆挤塑机中的熔融混炼制成。
在表1中，“聚缩醛”是指Delrin460，一种聚缩醛共聚物，由E.I.du Pont de Nemours and Co.，Wilmington，DE供应。在表2中，“聚酰胺”是指Zytel101L NC010，一种聚酰胺6，6，由E.I.du Pont deNemours and Co.，Wilmington，DE供应。在表1中，“蓝颜料”是指酞菁蓝，而“紫颜料”是指二二烯(dioxadine)紫颜料。
组合物被模塑成激光焊接用的试样条。获得的试样条的颜色用肉眼评估并载于表1和2中。
激光焊接强度
图1-3披露用于测定激光可焊性和焊接强度的典型试样件11的几何形状，如本文中对实施例2-9和对比例2-6所报道的。试样件11的形状大致为矩形，尺寸为70mm×18mm×3mm并在一端有20mm深半凹台(half lap)。半凹台由接触表面13和立面(riser)15限定。
在图4中，试样件11′为相对透明聚合物试样件，而试样件11″为相对不透明聚合物试样件，每一个试样件(11′和11″)具有上面描述的典型试样件11的形式和尺寸。试样件11′和11″的接触表面13′和13″分别被置于接触状态从而在二者之间形成接合17。相对透明试样件11′限定了被沿箭头A方向运动的激光辐射19撞击的撞击表面14′。激光辐射19穿过相对透明试样件11′并照射相对不透明试样件11″的接触表面13″，从而导致试样件11′和11″在接合处被焊接在一起，由此形成试样条21。
实施例2-9和对比例2-6：
对应于实施例2-9和对比例2-6的树脂组合物被模塑成相对不透明试样件11″。在实施例2-4和对比例2-5的情况下，Delrin460被模塑为相对透明试样件11′。在实施例5-10和对比例6的情况下，Zytel101L NC010被模塑成相对透明试样件11′。
在每种情况下，试样件11′和11″按如上所述在0.3MPa加紧压力的条件下被焊接在一起形成试样条21。激光辐射从Rofin-Sinar LaserGmbH 940nm二极管激光器射出。激光束聚焦成直径3mm并以表1和2的小标题“焊接速率”的一栏内所示的速率沿着试样件11′和11″的宽度通过一次。激光功率在约50-455W之间变化。
对分开所得试样条21的11′和11″试样件所需的力，使用ShimadzuSeisakusho制造的Shimadzu Autograph试验机(其夹紧于试样条的台肩)进行测定，其中拉伸力沿着试样条的纵向施加。试验机在2mm/min的速度下操作。如果需要大于1kgf的力来分开试样件，则认为它们是激光可焊的，正如在表1和2中所示。如果在激光焊接期间试样件之间没有粘附力，则认为它们不具有激光可焊性，正如在表1和2中所示。针对每种组合物提供最佳焊接强度的功率在表1和2的小标题“激光功率”的一栏内给出。所得焊接强度在表1和2的小标题“激光焊接强度”的一栏内给出。
对比例1：
图5公开了由对比例1的组合物模塑的相对不透明试样件30的几何形状，其用于测定如本文中所报道的对比例1的激光可焊性和焊接强度。试样件30大体呈矩形，具有40mm×20mm×3.2mm的尺寸。图5还披露相对不透明试样件32的几何形状，其也用于测定如本文中所报道的对比例1的激光可焊性和焊接强度。试样件32由Delrin460模塑并大体呈矩形，具有40mm×20mm×1.6mm的尺寸。各个试样件以其表面彼此搭接接触形成它们之间的接合34并在0.3MPa压力下夹紧。相对透明试样件32限定了沿箭头A的方向运动的激光辐射19撞击的撞击表面36。激光辐射19穿过相对透明试样件32并照射相对不透明试样件30的表面并试图借此使试样件30和32在接合34处焊接在一起结果形成试样条38。激光辐射从Rofin Sinar Laser GmbH 940nm二极管激光器射出。激光束被聚焦为直径3mm并沿着30和32的宽度以50-500cm/min的速度和以200W的功率通过一次。该激光焊接不成功而且在所尝试的速度下，在试样件30和32之间没有形成粘合。
实施例1：
图6和7公开由实施例1的组合物模塑的相对不透明试样件40的几何形状。试样件40的形式是圆敞口碗状物体，用作玩具陀螺(toy top)的底座并具有唇44。图6-8公开由Delrin460模塑的相对透明试样件42的几何形状。试样件42是圆盘，用作玩具陀螺的盖子并具有中心孔46和唇48。附图标记50指的是玩具陀螺的转子，其具有底座52和杆54。底座52插入到试样件40中，然后将试样件42放在试样件40顶面，以便使杆54穿过孔46并让试样件42的下表面接触唇44的上表面。
继续参见图6和7，试样件42在0.3MPa压力下被夹紧到试样件40。激光辐射19在试样件42接触唇44的点处通过相对透明试样件42并照射相对不透明试样件40的表面，从而使试样件40和42焊接成为玩具陀螺形式的试样件56。在焊接过程中，激光辐射沿径向围绕试样件42通过一次，以致其运动以150cm/min的速度描绘一个圆。激光辐射从Rofin Sinar Laser GmbH 940nm二极管激光器射出。激光束聚焦成直径0.3mm并在30W的功率下操作。
焊接强度的测定是利用Shimadzu Seisakusho制造的ShimadzuAutograph试验机将试样件56夹紧在圆柱体钢夹具上并对杆54施加向下的力来实施的。分开焊接试样件40和42所需要的力示于表1。
因此，显然本发明提供了一种激光可焊热塑性聚合物组合物和激光焊接方法，它们完全满足前面所举出的目的和优点。虽然已就本发明具体实施方案对其做了描述，但显然许多替代、修改和变换对于本领域技术人员是显而易见的。因此，意图是涵盖所有落在所附权利要求的精神和广义范围的此类替代、修改和变换。
