Description

一种含有石墨烯的耐热膜
技术领域
本发明涉及一种耐热膜，特别是涉及一种含有石墨烯的耐热膜。
背景技术
在通信及电子行业，电子产品及网络产品在制作过程中，会使用到一些膜材料，同时对这些膜材料有较高的要求，如具有较好的耐热性，这样可以避免温度过高对设备或产品产生不良的影响。石墨烯具有非常多的优点，石墨烯应用到耐热膜当中的研究目前非常少，但是非常具有前景，因此开发一种含有石墨烯的耐热膜有良好的应用前景。
发明内容
要解决的技术问题：常规耐热膜耐热温度较低的问题。
技术方案：一种含有石墨烯的耐热膜，由以下成分按照重量比组成：石墨烯1～3份，氧化镁10～20份，PET改性酚醛树脂10～20份，甲基硅树脂10～15份，氧化铝5～10份。
制备方法：通过旋转涂敷法来制备耐热膜，具体过程如下：首先称取石墨烯1～3kg，氧化镁10～20kg，PET改性酚醛树脂10～20kg，甲基硅树脂10～15kg，氧化铝5～10kg。将上述成分调配均匀后，在旋转的基板表面涂覆上述调配好的铸膜液，涂覆后膜的厚度为1um以下。50℃下放置20h，晾干后即可得到含有石墨烯的耐热膜。
有益效果：含有石墨烯的膜具有良好的耐热性。
具体实施方式
实施例1
首先称取石墨烯1kg，氧化镁10kg，PET改性酚醛树脂20kg，甲基硅树脂10kg，氧化铝5kg。将上述成分调配均匀后，在旋转的铜板表面涂覆上述调配好的铸膜液，涂覆后膜的厚度为0.3um。
实施例2
制备方法同实施例1，具体成分含量如下：首先称取石墨烯3kg，氧化镁20kg，PET改性酚醛树脂10kg，甲基硅树脂15kg，氧化铝10kg，涂覆后膜的厚度为1um。
实施例3
制备方法同实施例1，具体成分含量如下：首先称取石墨烯2kg，氧化镁15kg，PET改性酚醛树脂15kg，甲基硅树脂12kg，氧化铝8kg，涂覆后膜的厚度为0.7um。
耐热性测试
将上述实施例1、实施例2、实施例3获得的膜进行耐热性测试，放入温度为800℃烘箱中，烘烤时间为20h，20h后实施例1、实施例2、实施例3的产品均未有起泡或裂开现象，具备了良好的耐热性。
