High-strength high-density carbon material as well as preparation method and application thereof
The invention discloses a high-strength high-density carbon material as well as a preparation method and application thereof. The preparation method comprises the following steps: S1, mixing at leastone of petroleum coke powder, pitch coke powder and mesocarbon microbeads having self-adhesion with a phenolic resin binder to obtain a mixed material, and crushing the mixed material to obtain mixedpowder; S2, performing compression molding and/or isostatic pressing on the mixed powder to obtain a blocky green body; and S3, carrying out carbonization graphitization sintering treatment on the blocky green body under the condition of air isolation to obtain the high-strength high-density carbon material. The high-strength high-density carbon material is prepared by using the preparation methodand can be applied to growth of glass hot bending molds, continuous casting molds, electric spark electrodes or polycrystalline silicon for solar energy. The carbon material which has good mechanicalproperties and can be applied to the fields of 3D glass hot bending molds and the like can be obtained only through one-shot sintering without dipping treatment.
本发明公开了高强高密炭素材料及其制备方法和应用，制备方法包括以下步骤：S1：将具有自粘性的石油焦粉、沥青焦粉和中间相炭微球中的至少一种与酚醛树脂粘结剂混合得到混合材料并将混合材料粉碎得到混合粉料；S2：将所述混合粉料通过模压成型和/或等静压成型压制得到块状坯体；S3：将所述块状坯体在隔绝空气的条件下进行炭化石墨化烧结处理得到所述高强高密炭素材料。高强高密炭素材料由上述制备方法制得，该高强高密炭素材料能够应用在玻璃热弯模具、连续铸造模具、电火花电极或太阳能用多晶硅生长中。本发明不需要再进行浸渍处理且仅通过一次性烧结即可获得具有良好力学性能且能够应用于3D玻璃热弯模具等领域中的炭素材料。
