本发明涉及一种组合物,该组合物含有一种具有高热传导率的聚酰胺基体,并且包括一种氮化物和一种金属氧化物,以及任选的一种阻燃体系。所述组合物可以特别地用于生产用于照明装置的部件(包括电致发光二极管)。
Description
本发明涉及一种组合物,该组合物基于聚酰胺基体并且展现高的热传导率并且包括一种氮化物和一种金属氧化物以及可能还有一种阻燃体系。这种组合物可以特别地用于生产用于照明设备的部件(发光二极管)。
现有技术
聚酰胺是一种广泛用于制造多种物品(例如模制品和/或注塑模制品)的合成聚合物。工业聚酰胺在不同领域例如机动车、电学的或电子的领域用于大批物品的制备,其刚度、耐冲强度、尺寸稳定性的特殊性能,特别是在相对高的温度下,其表面状况、密度和重量为特别所希望的。针对给定应用的材料选择总体上是由关于某些特性所要求的性能水平以及其成本所引导的。事实上,一直在寻求能够满足性能和/或成本方面要求的新材料。
从已有技术中已知,使用工业聚酰胺对不同的应用具有良好的热传导率,特别是在电学的或电子的领域,当其与半导体、发动机、或发光或与光相互作用的部件使用时。这样,电致发光二极管(LED)是当它们通过电流时能够发光的电子的部件,该电流产生强热然后适当的消散,目的是预防热区和引起损坏。
已知将由聚酰胺制成的部件用于通过使用能够增强聚酰胺的热传导率的添加剂(例如像石墨或氮化硼)制备这样的包括LED的物品。然而,在聚酰胺中石墨的使用也导致了电传导率的强增长,特别是在文件FR 2596 567中所提到的。
因此,存在发明在不同的应用具有一个在机械学和阻燃性的良好的折衷的同时,具有高的热传导率以及低的电传导率(这就是说良好的电绝缘)的聚酰胺基组合物的需要。
此外,已知当矾土在聚酰胺中以非常高的比例使用时,使其有可能给予一个热传导率的程度。然而,基体中矾土的这样一个比例导致在聚酰胺组合物的机械学和流变性质上的急剧的恶化。
