Preparation method of pantograph carbon slider composite material
The invention relates to the technical field of carbon slider preparation, more specifically to a preparation method of a pantograph carbon slider composite material. According to the invention, ironoxide red, cobalt powder, hafnium oxide, nickel powder, copper powder, carbon black, graphite powder and the like are added into raw materials and fused with other materials in the raw materials, so that the mechanical strength of a finished product carbon slider can be supplemented, and the finished product carbon slider is not prone to breaking and cracking. The preparation process comprises thefollowing steps: grinding the raw materials, carrying out compression molding and copper immersion, and finally sintering and carbonizing, thereby enhancing the density and strength of the carbon slider material. The volume density of the prepared pantograph carbon slider composite material is 8.0-9.0 g/cm<3>, the tensile strength is greater than or equal to 180 Mpa, the impact toughness is greater than or equal to 12J/cm<2>, the resistivity at 20 DEG C is less than or equal to 0.20 mu omega.m, and the Rockwell hardness (HBS) is 60-100.
本发明涉及碳滑板制备技术领域，更具体而言，涉及一种受电弓碳滑板复合材料的制备方法，通过在原料中加入铁红、钴粉、氧化铪、镍粉、铜粉、炭黑、石墨粉等，与原料中的其他材料相融合，可以补充成品碳滑板的机械强度，使其在运行中不易折断和破裂；其制备工艺是，首先对原料进行研磨，再通过模压成型、浸铜工艺、最后烧结炭化处理，可以增加碳滑板材料的密度和强度。制备的受电弓碳滑板复合材料体积密度8.0‑9.0g/cm、抗拉强度≥180Mpa、冲击韧性≥12J/cm、20℃电阻率≤0.20µΩ·m、洛氏硬度（HBS）60‑100。
