The invention discloses a ceramic-based composite material applied to mining explosion-proof lamps and a preparation method of the ceramic-based composite material, and relates to the technical field of mining operation materials. The ceramic-based composite material is prepared from the following raw materials in parts by weight: 60-65 parts of high-purity alpha-Al2O3, 3-5 parts of silicon nitride, 10-20 parts of SiC fibers, 3-5 parts of short carbon fibers, 1-3 parts of graphene sheet layers and 1-4 parts of additives. The SiC fiber, the short carbon fiber and the graphene are added to form a three-dimensional reinforced network, so that the tensile strength, the compressive strength and the fracture toughness of the composite material are remarkably enhanced, the composite material can bear frequent vibration and impact in a mine, and the service life of a lamp is prolonged; compared with a traditional metal material, the composite material has the advantages that the weight of the lamp is obviously reduced, and the transportation and operation cost is reduced; the invention not only overcomes the limitation of the existing mining explosion-proof lamp material, but also shows obvious advantages in the aspects of improving the lamp performance, reducing the cost, guaranteeing the production safety and the like, and provides important material support for the progress of the mine lighting technology.
本发明公开了一种矿用防爆灯具应用的陶瓷基复合材料及其制备方法，包括以下重量份组成的原料：高纯度α‑Al2O360～65份、氮化硅3～5份、SiC纤维10～20份、短切碳纤维3～5份、石墨烯片层1～3份以及添加剂1～4份，本发明涉及矿用作业材料技术领域，通过添加SiC纤维、短切碳纤维以及石墨烯，形成三维增强网络，显著增强了复合材料的抗拉强度、抗压强度及断裂韧性，使其能够承受矿井中频繁的震动和冲击，延长灯具寿命；相比传统金属材料，本发明的复合材料显著减轻了灯具的重量，降低了运输和操作成本；本发明不仅克服了现有矿用防爆灯具材料的局限性，而且在提升灯具性能、降低成本、保障生产安全等方面展现出显著优势，为矿井照明技术的进步提供了重要的材料支撑。
