The invention relates to the technical field of preparation of carbon sliding strips, in particular to a method for improving the mechanical strength, the conductivity and the impact resistance of a pantograph carbon sliding plate material. TiC, ZrC, WC, VC, SiC, CU, carbon black, graphite powder and the like are added into raw materials and fused with other materials in the raw materials, so thatthe mechanical strength of the finished carbon sliding plate can be supplemented, and the finished carbon sliding plate is not prone to being broken and fractured in the operation process; the preparation process comprises the following steps: firstly grinding the raw materials, and then carrying out compression molding, copper immersion process, roasting and electrifying purification treatment to increase the density and the strength of the carbon slide plate material. The volume density of the prepared pantograph carbon sliding strip is smaller than or equal to 3.8 g/cm < 3 >, the breakingstrength is larger than or equal to 80, the compressive strength is larger than or equal to 100, impact toughness is larger than or equal to 0.2 J/cm < 2 >, 20-DEG C resistivity is smaller than or equal to 5 mu omega.m, and Rockwell hardness (HBS) is smaller than or equal to 80.

    本发明涉及碳化条制备技术领域,更具体而言,涉及,以提高受电弓碳滑板材料的机械强度、电导性和耐冲击性能。通过在原料中加入TiC、ZrC、WC、VC、SiC、CU、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、焙烧、通电纯化处理,可以增加碳滑板材料的密度和强度。制备的受电弓碳化条体积密度≤3.8g/cm、抗折强度≥80、抗压强度≥100、冲击韧性≥0.2J/cm、20℃电阻率≤5µΩ·m、洛氏硬度(HBS)≤80。
