The invention relates to the technical field of carbon strip preparation, and discloses a preparation method of a directly sintered carbon strip for a pantograph carbon slide plate, and the preparation method comprises the following steps: S1, green coke powder separation: R aggregate: 30 meshes; the powder R is 120 meshes; the particle size D50 of the R fine powder is 45 microns, and the particle size D50 of the R fine powder is 8 microns; s2, proportioning: proportioning the raw materials with different granularities, wherein R aggregate is equal to 40%; r powder is equal to 40%; r fine powder D50 is 45 microns and is equal to 6%; r fine powder D50 is 8 microns and is equal to 4%; carbon black = 3%; stearic acid = 2%; the content of mesophase carbon microspheres is 2%; the coal-based pitch is equal to 3%. By applying the self-sintering characteristic of the material, particles are mutually bonded and shrunk in the sintering process, so that the material has relatively high density, the required mechanical property is directly achieved, repeated dipping and sintering processes are not needed, and the production period is greatly shortened; and compared with a traditional sintering mode, the sintering time is shorter, and the related cost is greatly saved.
本发明涉及碳条制备技术领域，且公开了一种直接烧结的受电弓碳滑板用碳条的制备方法，包括以下步骤：S1、生焦粉料分机：R骨料：30目；R粉料：120目；R细粉：一种粒度D50=45微米，一种粒度D50=8微米；S2、配料，将不同粒度的原料进行配比：R骨料=40%；R粉料=40%；R细粉D50=45微米=6%；R细粉D50=8微米=4%；炭黑=3%；硬脂酸=2%；中间相碳微球=2%；煤系沥青=3%。本发明通过运用材料本身的自烧结特性，在烧结过程中颗粒相互粘结收缩，使材料具有较高密度，直接达到所需力学性能，不需要多次重复浸渍与烧结工艺，大大缩短了生产周期；与传统的烧结方式比，烧结时间更短，大大节省了相关成本。
