Zusammenfassung
(EN)
The invention discloses a preparation method of a porous carbon heat-insulating composite material and aims to solve the problem that existing porous carbon heat-insulating composite material preparation methods are long in process period, serious in volume shrinkage during carbonization and large in potential safety hazard. The preparation method includes: using ion liquid as a carbon precursor, an eutectic-salt mixture as a pore foaming agent and an inorganic carbon fiber prefabricated member as enhancosome; grinding and mixing the ion liquid and eutectic-salt mixture; increasing temperature for fusion under protection of high-pressure inert gas; mixing with the carbon fiber prefabricated member; continuing increasing temperature to enable the ion liquid to be carbonized into porous carbon to obtain a carbon fiber enhanced porous carbon/salt complex; subjecting the carbon fiber enhanced porous carbon/salt complex to cooling, water washing and drying to obtain the carbon fiber enhanced porous carbon heat-insulating composite material. The preparation method is simple in process, short in period, small in potential safety hazard and environment-friendly, and the carbon fiber enhanced porous carbon heat-insulating composite material prepared by the method is low in heat conductivity, good in heat-insulating performance, free of surface cracking and more conducive to preparing special-shaped components.

本发明公开了一种多孔炭隔热复合材料的制备方法,目的是解决现有多孔炭隔热复合材料制备方法工艺周期长、炭化过程中体积收缩大、安全隐患大等问题。技术方案是以离子液体作为炭前躯体,低共熔盐类混合物作为致孔剂,无机炭纤维预制件作为增强体,首先将离子液体和低共熔盐类混合物研磨混合,在高压惰性气体保护下升温熔融后与炭纤维预制件混合,继续升温使离子液体炭化形成多孔炭,得到炭纤维增强多孔炭/盐复合体,再经过冷却水洗干燥后获得炭纤维增强多孔炭隔热复合材料。本发明制备工艺简单,周期短,安全隐患小、绿色环保,且制备的炭纤维增强多孔炭隔热复合材料热导率低,隔热性能好,表面不会开裂,更有利于制备异形构件。
