Preparation method for preparing hollow nest-shaped anti-damage engineering material base material from coal solid waste or bauxite solid waste by using sintering method
The invention particularly relates to a preparation method for preparing a hollow nest-shaped anti-damage engineering material base material from coal solid waste or bauxite solid waste by using a sintering method. Kaolinite and boehmite which are rich in lithium and gallium rare metal elements in the coal solid waste are used as a combustion aid and a volatilization aid, a hollow nest-shaped hollow-core substrate composed of boron carbide and corundum particles is prepared by using the volatilization characteristic of boron carbide in the sintering process, and the substrate is put into a metal, metal alloy and high polymer molecular material solution which is required by a design function and has a certain temperature for infiltration at set pressure, so as to obtain a boron carbide-based metal, metal alloy and high polymer molecular composite engineering material which meets the design function requirement. Metal elements contained in the substrate raw material are precipitated at the bottom of the substrate in a liquid phase form in the sintering process of the substrate to form hard underpinning, so that the requirement for moving the substrate is just met, and the bonding effect between the boron carbide-based polymer anti-damage engineering material and a ceramic constrained metal material is greatly enhanced.
本发明具体涉及一种利用煤炭固废或铝矾土固废使用烧结法制备中空鸟巢状防毁伤工程材料基材的制备方法；使用煤炭固废中富含锂、镓稀有金属元素的高岭岩及勃姆石做燃烧助剂及挥发助剂，利用碳化硼烧结过程中的挥发特性、制备出中空鸟巢状由碳化硼与刚玉微粒组成的空芯基板，并将此基板放置入设计功能所需且具有一定温度金属、金属合金、高聚分子材料溶液中给予设定压力进行浸润，从而得到达到设计功能要求的碳化硼基金属、金属合金、高聚分子复合工程材料；其中，基板原料中所含金属质元素在基板烧结过程中以液相形式沉淀在基板底部形成硬质托底，恰好解决基板移动所需，并大大增强碳化硼基高分子防毁伤工程材料与陶瓷约束金属材料之间的粘合作用。
