High-strength and high-toughness graphite and preparation method thereof
The invention provides high-strength and high-toughness graphite and a preparation method thereof. The preparation method comprises the following steps: step 1, heating, mixing and kneading coke aggregate, short carbon fibers and a binder to obtain a paste material; 2, cooling the paste material, crushing, and carrying out isostatic compaction to obtain a green body; step 3, carbonizing the green body to obtain a carbonized product; and step 4, carrying out graphitization treatment on the carbonized product to obtain the high-strength and high-toughness graphite. According to the preparation method of the high-strength and high-toughness graphite disclosed by the embodiment of the invention, the short carbon fibers are added into the fine-particle coke aggregate, and the high-strength and high-toughness graphite is obtained after isostatic compaction, carbonization and graphitization treatment.
本发明提供一种高强度高韧性石墨及其制备方法。其中，制备方法包括如下步骤：步骤1，将焦炭骨料、短切碳纤维、以及粘结剂进行加热混捏，得到糊料；步骤2，将所述糊料冷却后进行粉碎，并进行等静压成型，得到生坯；步骤3，将所述生坯进行炭化处理，得到炭化产物；步骤4，将所述炭化产物进行石墨化处理，得到所述高强度高韧性石墨。根据本发明实施例的高强度高韧性石墨的制备方法，在细颗粒的焦炭骨料中，加入短切碳纤维，在经等静压成型、炭化、石墨化处理后，得到高强度、高韧性的石墨。
