Abstract
本发明涉及提高由合成材料、特别是聚碳酸酯制成的模制部件表面的粘附稳定性的方法。
Description
技术领域
本发明涉及提高塑料模制品、特别是聚碳酸酯模制品表面的粘附稳定性的方法。
背景技术
聚碳酸酯可根据已知方法制造。适用于制造聚碳酸酯的方法例如有：由双酚与光气根据相界面法的制造方法、或由双酚与光气根据均相中的方法即所谓的吡啶法的制造方法、或由双酚与碳酸酯根据熔融酯交换法的制造方法。这些制造方法例如述于H.Schnell著的“Chemistry and Physics of Polycarbonates(聚碳酸酯化学和物理)”(Polymer Reviews(聚合物综述)第9卷31-76页，IntersciencePublishers，纽约，伦敦，悉尼，1964，)。所述的制造方法还述于D.Freitag，U.Grigo，P.R.Müller和H.Nouvertne著的“Polycarbonates(聚碳酸酯)”(Encyclopedia of Polymer Science and Engineering(聚合物科学与技术百科全书)第11卷，第2版，1988，648-718页)，以及U.Grigo，K.Kircher和P.R.Müller著的“Polycarbonate(聚碳酸酯”(Becker，Braun，Kunststoff-Handbuch第3/1卷，聚碳酸酯，聚缩醛，聚酯，Celluloseester，Carl Hanser Verlag München，Vienna 1992，117-299页)。
熔融酯交换法具体述于H.Schnell著的“Chemistry and Physics ofPolycarbonates(聚碳酸酯化学和物理)”(Polymer Reviews(聚合物综述)第9卷44-51页，Interscience Publishers，纽约，伦敦，悉尼，1964)和DE-A 1031512、US-A 3,022,272、US-A 5,340,905和US-A 5,399,659中。
在聚碳酸酯的制造中使用杂质含量低的原料和辅助物质较好。特别是在根据熔融酯交换法制造时，应尽可能使所用的双酚和所用的碳酸衍生物不含碱金属离子和碱土金属离子。这样的纯原料可由例如碳酸衍生物(如碳酸酯)和经重结晶、洗涤或蒸馏的双酚获得。
在根据熔融酯交换法制造聚碳酸酯时，双酚和碳酸二酯的反应可连续或不连续地在例如搅拌釜、薄膜蒸发器、降膜蒸发器、串联搅拌釜、挤出机、捏合机、简单圆盘型反应器和高粘度圆盘型反应器中进行。
为了更好地使由此方法制成的强吸湿性强聚碳酸酯能进行后面的工艺，通常在制造后将其立即造粒。
聚碳酸酯颗粒也可根据已知方法制成各种半成品或模制品。这些加工技术的例子有挤出法、注塑法和挤坯吹塑法。半成品的例子有薄膜、实心板、两壁板、型材和管子。这些聚碳酸酯可用于各种用途。它们用于电子工程、汽车工程、建筑工程或数据存储中。
现今，如果为了随后的用途(如作为光学数据载体)而要用金属膜蒸气镀覆碳酸酯模制品，必须要对模制品的表面进行特别处理，以增加被镀覆的金属膜和模制品之间的粘附性。
已经发现，聚合物颗粒中所含的夹带水(溶解水)会导致在镀覆由此制成的模制品时产生问题，因为粘附稳定性、特别是含水量在表面上不均匀分布时的粘附稳定性对于金属膜的最佳粘附性会太低。
发明内容
因此，本发明的目的是提高塑料模制品表面的粘附稳定性，以使它和随后镀覆的金属膜的粘附性最佳。
根据本发明，第一方法是通过在造粒过程中已经调节好颗粒中夹带水的比例，达到了此目的。
另一方面，本发明规定要调节半成品中夹带水的比例。夹带水的比例优选小于0.01％(100ppm)。
为了使聚碳酸酯颗粒在聚合后也保持或呈现出特定的含水量，本发明还提出要使颗粒或半成品升温至某一温度。通过加热颗粒或半成品，就能获得规定和均匀分布的水的比例，因此由这些颗粒或半成品制成的模制品从其含水量看是最佳的，这样就可保证没有缺陷地进行随后的镀覆。
为了使调节过水的比例的颗粒或半成品在制成模制品以前，其水的比例不因环境影响(如大气中的湿气等)而变化，本发明还要求颗粒或半成品在制成模制品以前以气密方式储存。
如果以这种方式储存的颗粒或半成品的气密性包装只在制成模制品之前打开短的时间，这就确保了由所述的颗粒或半成品制成的模制品表现出足够的粘附稳定性，以保证了模制品和金属镀膜之间的可靠粘附性。
具体实施方式
为了检验聚碳酸酯在不同湿度下的储存对粘附性的影响程度，将大小为1.5厘米×1.5厘米的PC片在特定湿度下储存14天。随后，在高真空蒸发单元中在试样片上镀覆200纳米的铝膜。用解剖刀在镀金属膜的一面上刻出网格。为了保证网格大小相同，借助于以1.5毫米间距铣出带条的蒙片(mask)来刻网格。
以180°的角度用7.5牛的恒力剥下已经覆盖在上面的15毫米宽粘合带(tesaDocument-Film 5730000000，Beiersdorf)。只有在0％大气湿度下储存的试样(储存在装有蓝色硅胶的容器中)显示铝膜没有脱落或略微脱落。在其余的试样(24％和100％大气湿度)的情况下，铝膜已经完全脱落。在储存于24％大气湿度下的试样中，通过称重确定残余的水含量为0.4％；在储存于100％大气湿度下的试样中，残余的水含量为2.8％。
在4小时内将含水量为1.5％的PC试样加热到140℃，使含水量降低到随后能达到良好粘附性的程度(0.1％)。
在除去水分并且还存在干燥剂的条件下储存，使得颗粒状态下或者甚至半成品状态下的含水量减少到能达到良好粘附性的程度，其粘附性就像用在装有蓝色硅胶的容器中储存14天的PC片进行的实验中获得的粘附性那样。
本发明避免了额外工艺步骤，即在制造模制品之前重复除去吸湿性颗粒或半成品中的水，本发明通过在制造颗粒时或在制造半成品时已经将夹带水的比例减少到一定程度，使颗粒或半成品得到适当的储存，因此不再需要在制造模制品前进行额外的干燥步骤。
