Description

一种聚氨酯复合材料
技术领域
本发明涉及聚氨酯领域，具体的说是一种聚氨酯复合材料。
背景技术
热可塑性聚氨酯(TPU)弹性体，是由含NCO官能基的二苯基甲烷二异氰酸酯(MDI)与含0H官能基的多元醇(POLYOL)、1，4丁二醇(1，4-BG)经押出混炼而制成，由于弹性好、物性佳、各种机械强度都很好，因此广泛用于射出、押出、压延及溶解成溶液型树脂等加工方式，是塑胶加工业者经常使用的塑胶材料，其制成的产品涵盖了工业应用和民用必需品的范围。TPU不仅拥有卓越的高张力、高拉力、强韧和耐老化的特性，而且是成熟的环保材料；目前TPU已被广泛应用于电子电器、汽车、日常用品等。但是，TPU的缺点是导热性能较差。
随着市面上对于电子产品的要求有轻量化、小型化趋势，其中对电子电器元件及汽车电子元件又有高散热要求。但传统的导热材料一般为金属制品，其显著特点是高导热，但金属制品比重较大、加工困难。目前常见的导热聚合物材料如导热PPS等，其主要为硬质工程塑料，不能满足汽车电子组件产品对于材料柔韧性的要求。。
发明内容
为了弥补现有技术的不足，本发明提供一种具有柔韧性好、导热系数高、质轻的聚氨酯复合材料。
本发明解决其技术问题所采用的技术方案是：一种聚氨酯复合材料，按照重量份计，包括以下组分：
优选的，所述纳米氧化铝粉的粒径为20-40nm。
优选的，所述的抗氧剂为β(3，
5-二叔丁基-4羟苯基)丙酸季戊四醇酯和三(2，4-二叔丁基苯酚)亚磷酸酯的混合物。
优选的，所述的β(3，5-二叔丁基-4羟苯基)丙酸季戊四醇酯和三(2，4-二叔丁基苯酚)亚磷酸酯的质量比为3∶5。
有益效果：聚氨酯复合材料以乙酸乙酯和异氰酸酯聚氨酯为主料，通过在聚氨酯中分散镁粉来提高导热性能，另外通过竹炭纤维与镁粉相互协同作用，提高聚氨酯复合材料的导热系数。
具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合实施方式，进一步阐述本发明。
本发明所述的一种聚氨酯复合材料，按照重量份计，包括以下组分：
优选的，所述纳米氧化铝粉的粒径为20-40nm。
优选的，所述的抗氧剂为β(3，
5-二叔丁基-4羟苯基)丙酸季戊四醇酯和三(2，4-二叔丁基苯酚)亚磷酸酯的混合物。
优选的，所述的β(3，5-二叔丁基-4羟苯基)丙酸季戊四醇酯和三(2，4-二叔丁基苯酚)亚磷酸酯的质量比为3∶5。
以上显示描述了本发明的基本原理、主要特征和优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中的描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附权利要求书及其等效物界定。
