Description
技术背景
本发明涉及一种运输工具前灯反光罩,该反光罩包括基体和反光涂层,基体由微粒填料和其它添加物混合而成的塑料制成,反光层直接涂在基体的表面上。
该反光罩由文件EP0184554A1给出,它由基体和直接涂在基体上的反光层组成,该基体由微粒填料混合而成的塑料制作,塑料用热固性塑料,可实现如下基体表面质量,即直接在基体上涂反光层而无需附加中间涂层。尽管如此,由于一般的热固性塑料具有较小的热形状不变性,使得塑料基体的反光罩因前灯的光源的工作所产生的热量而变形。这违反关于前灯光分布的现有法律规定。为了达到反光层良好的耐抗性,必须选择合适的基体材料。
本发明优点
本发明提出的反光罩的特征为,塑料为热固性塑料,塑料的pH值在6-8之间,其具有下述优点,由于采用热固性塑料基体,因而具有良好的耐抗性,并避免了上述的缺点。此外,用pH值在6-8之间的填料确保了反光层的良好的耐抗性。
在权利要求中将说明本发明极具优点的设计和详细构成。
附图
图中给出了本发明的两个实施例,后面将作进一步地说明,图1是反光罩的纵截面图。
实施例描述
一种图1中所示的用于运输工具,特别是用于汽车前灯的反光罩,其由通过注塑或压铸而成的基体10以及通过在其凹形内表面12直接涂上而无需附加中间涂层的反光层14组成。
该反光罩的基体10由微粒填料和其它附加材料混合而成的热固性塑料制成,填料的pH值在6-8之间,优选pH值在6.5-7.5之间,特别是pH值约为7的填料,且填料是化学中性的。颗粒尺寸最大为1μm,基体由大量该颗粒组成,颗粒在基体加工前后应尽可能均匀地分布在基体内。
用来制作基体的填料最少占总重量的40%,填料占总重量的份额优选在50%-70%之间,也可以使用几种不同填料的混合物,但共同占总重量的份额应与上述值相同。
在第一个实施例中应用一种未饱和的聚酯材料,如聚酯树脂作为热固性塑料,未饱和的聚酯树脂与低光滑度添加剂(Low-profile-Additiv)混合,在实例中比例关系为70%的聚酯树脂和30%的低光滑度添加剂,低光滑度添加剂所占的份额可以减少到0。
下面将给出制作基体10的量配方,组成物的量以占总重量的份额给出:聚酯树脂(也可用低光滑度添加剂):约占20%-30%填料: 最少:40%玻璃纤维: 约占5%-20%浓缩剂: 约占0%-1%添加物: 约占1%-5%
用玻璃纤维是为了达到基体足够的机械稳定性,此外,用添加物是为了达到外壳良好的可加工性,在第一个实例中外壳为一软型外壳,表示为BMC一外壳,即整体注塑合成外壳。
在第二个实例中用环氧树脂作为热固性塑料,这种塑料在加工前是松散的粒料,下面将给出制作基体10的配方,组成物的量以占总重量的份额给出:
环氧树脂: 约占30%-50%
填料: 最少40%
玻璃纤维: 约占0%-5%
添加物: 约占1%-5%
上述实施例中所给出的各组成物质在加工前均匀地混合并使其匀质化,如在辊式破碎机中进行均匀地混合并使其匀质化,接着通过在相应的模具如成基体10形状的模具中的注塑或压铸,该模具至少在要涂以反光层14的基体10的凹形内表面12范围内具有较低的表面粗糙度,优选粗糙度最大不在于0.2μm,基体在模具中成型后通过加温以一定的方式在模具中时效硬化。
接着要通过例如吹刷或清洗的方法使基体10的内表面12净化,一种存在的且许可的特殊情况使制造其内表面12具有非常小粗糙度的基体10成为可能,这种特殊情况就是,填料的平均最大颗粒度为1μm,模具具有较小的粗糙度,反光罩罩体10的内表面12的粗糙度最大不超过0.3μm,优选0.15μm,基体10较高的表面质量使得在其内表面12上可以不加任何附加涂层而直接涂上反光层14。
反光层14以一定方式涂在基体10的内表面12上,反光层14最好由铝组成,其最小反光度为90%。由于填料的化学中性,反光层在潮湿的影响下仍能达到很好的耐抗性。
