Description

快速成型碳碳复合3D打印材料
技术领域
本发明涉及一种快速成型碳碳复合3D打印材料，属于材料技术领域。
背景技术
3D打印也称为快速成型制造技术，其制造过程是通过对三维模型分层离散处理，将每一层的资料传输到3D打印机，利用激光，紫外光照，热熔喷嘴等方式将金属、陶瓷粉末、塑料或者细胞组织等材料进行逐层堆积进而粘结成型，最终制造出整个材料或者器件。3D打印具有制造过程简单、产品开发周期短、易于制造复杂形状部件，多个部件可以一体化成型，零件加工余量小，节约材料等特点。
作为3D打印的核心部件的打印材料近年来一直受到广泛的关注。逐步开发出了陶瓷、光敏树脂、金属合金、生物组织、复合材料以及塑料等不同的种类。根据打印材料形状的不同，可以分为丝状、粉末状以及液状材料。可以这样说，打印材料的种类的不同，就决定了3D打印机的种类与性能。材料是制约3D打印的一个重要的因素。
石墨烯是一种完全透明的碳材料，具有良好的导电的特性。是从石墨材料中剥离出来、由碳原子组成的只有一层原子厚度的二维晶体。
离子液体，顾名思义，就是完全由阴阳离子所组成的，在室温下呈液态的盐类化合物。与传统的固体盐不同，以液体状态存在的熔融盐分子具有可设计性，不同的阴阳离子能够组合出种类繁多的离子液体。通过选择不同的阴阳离子，或者直接引入特定的官能团进行修饰,对离子液体的性质，如熔点、粘度、疏水性进行调整，来满足不同的需要。离子液体因为没有明显测得的饱和蒸汽压，因而使用离子液体比使用传统的化学溶剂更加符合环境友好的绿色发展理念。离子液体具有可设计性，通过调整不同的阴阳离子对，能够设计出种类不同，满足不同需要的专门离子液体来。
发明内容
本发明公开了一种快速成型碳碳复合3D打印材料，该3D打印材料具有快速成型、耐高温，高强度，耐摩擦的特点；该材料经过打印成型后，作用持久，耐高温、导电且不易腐蚀的特点。对环境与使用人员无毒害作用。
