Description
技术领域
本发明涉及煤焦油沥青技术领域，尤其涉及一种高温煤焦油沥青。
背景技术
沥青主要可以分为煤焦油沥青、石油沥青和天然沥青三种：其中，煤焦油沥青是炼焦的副产品。石油沥青是原油蒸馏后的残渣。天然沥青则是储藏在地下，有的形成矿层或在地壳表面堆积。
煤焦油在加工过程中，通过蒸馏除去液体馏分后的残渣称为煤焦油沥青，煤焦油沥青是煤焦油的主要成分，约占总量的50%-60%。一般认为其主要成分为多环、稠环芳烃及其衍生物，化合物的具体组成非常复杂，原煤和加工工艺的不同也会导致组分的差异，目前的方法主要是基于软化温度来区分。根据蒸馏温度的不同，煤焦油沥青可分为低温煤焦油沥青、中温煤焦油沥青和高温煤焦油沥青。
在高、中、低温煤焦油沥青中，只有高温煤焦油沥青最适合作为炭素前驱体的原料；高温煤焦油沥青相比石油沥青具有更高的芳香组分含量，更易于实现石墨化并制成炭素材料；煤焦油沥青基炭素材料有着各种优越的特性，在各个领域的高精尖和前沿技术方面有着广阔的应用前景。但是高温煤焦油沥青相对中温煤焦油沥青和低温煤焦油沥青来说，制备工艺复杂、制备难度大、生产成本高。
发明内容
基于上述背景技术，本发明提供一种高温煤焦油沥青。
一种高温煤焦油沥青，包括中温煤焦油沥青和除尘粉，所述中温煤焦油沥青和除尘粉的质量比为3：1。
进一步的，所述除尘粉为针状焦或石油焦或沥青焦或天然石墨或人造石墨。
综上所述，本发明具有以下有益效果：
本发明的一种高温煤焦油沥青含碳量高，具有优异的导电及导热性能，且价格低廉，有利于煤焦油沥青的石墨化和炭素材料的生产。
实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明的实施例，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
一种高温煤焦油沥青，包括中温煤焦油沥青和除尘粉，所述中温煤焦油沥青和除尘粉的质量比为3：1。
进一步的，所述除尘粉为针状焦或石油焦或沥青焦或天然石墨或人造石墨。
将中温煤焦油沥青加热至液态，然后按上述比例加入除尘粉，并混合均匀，即可制得本发明的一种高温煤焦油沥青。在本实施例中，除尘粉是增碳剂，优选的，除尘粉为针状焦。
以上实施例仅用以说明本发明的技术方案，而非对其进行限制；尽管参照前述实施例对本发明进行了详细的说明，对于本领域的普通技术人员来说，依然可以对前述实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或替换，并不使相应技术方案的本质脱离本发明所要求保护的技术方案的精神和范围。
