Description
技术领域
本发明涉及散热降温纳米新材料领域,具体提供一种散热降温纳米粉。
背景技术
电子产品越来越普及,近期新兴的LED照明,更有全面取代传统节能灯照明的趋势。电子产品永远存在发热、散热问题,LED灯发热问题更严重,是制约LED灯发展的关键问题。因此,为了解决电子产品散热问题,提高降温效果,急需有新的散热降温新材料出现。
另外,传统的供暖电子产品,也需要把热量快速传递给周围,提高环境温度,若在供暖器的散热片表面喷涂散热降温纳米粉生产的涂料,能够轻易实现快速将热量辐射给周围环境,从而提高环境温度的效果。
发明内容
本发明经实验获得一种散热降温纳米粉,热辐射系数为98%。以该散热降温纳米粉为填料,可生产散热涂料,辐射涂料,散热油墨等产品,具有明显辐射散热降温效果。
本发明一种散热降温纳米粉末,其特征在于:包含35.0~40.0%质量且粒径为10~15μm的SiO2,12.0~15.0%质量且粒径为5~10μm的Al2O3,1.0~2.0%质量且粒径为3~5μm的Fe2O3,4.0~5.0%质量且粒径为1~5μm的ZnO,5.0~8.0%质量且粒径为500nm~1μm的MgO,8.0~10.0%质量且粒径为100nm~500nm的B2O3,4.0~6.0%质量且粒径为100nm~200nm的MnO,1.0~2.0%质量且粒径为50nm~100nm的Na2O,2.0~4.0%质量且粒径为50nm~100nm的Li2O,3.0~5.0%质量且粒径为50nm~100nm的ZrO,8.0~10.0%质量且粒径为20nm~50nm的BN,0.5~1.0%质量且粒径为10nm~50nm的SiC,0.5~1.0%质量且粒径为10nm~50nm的TiO,余量为不可避免杂质。
本发明一种散热降温纳米粉,热辐射系数高达98%。以该散热降温纳米粉为填料生产散热降温涂料,辐射涂料,散热油墨,都具有明显降温效果。譬如LED灯壳,常见结构的灯壳散热器,表面有喷涂散热纳米粉为填料生产的散热涂料,比没有喷涂的,会多降温5~25%,降温幅度与具体散热器结构有很大关系。
散热纳米粉为填料生产的辐射涂料,喷涂在供暖器的散热器表面,可以大大提高热传导效率,快速提高周围环境温度。
若直接将散热降温纳米粉溶入布料,则可以生产很保暖的保暖内衣。
具体实施方式
下面对本发明优选实施例进行进一步说明。发明内容中表述的成份组合及质量比范围均属于本发明的保护范围,实施例不视为对本发明保护范围的限制。
实施例,本实施例散热降温纳米粉,以下罗列六种不同质量百分占比:
