Description

一种散热降温纳米粉新材料
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：
