Wood pyrolysis modification method for preparing biological ceramic-based composite material
The invention belongs to the technical field of ceramics and ceramic-based composite materials, and discloses a wood pyrolysis modification method for preparing a wood-derived biological state ceramic-based composite material, which comprises the following steps: carrying out pyrolysis modification on a wood block at a high temperature (250-600 DEG C) to obtain a dipping template with good permeability; the ceramic-based composite material impregnated templates with different permeability can be prepared by regulating and controlling the pyrolysis temperature. The method is easy to operate, the ceramic-based composite material dipping template with a complete pore structure and a good permeation effect can be prepared, and related pyrolysis modification equipment is simple in structure and high in practicability; according to the method, the ceramic-based composite material impregnation template with the optimal permeation effect can be obtained by controlling the pyrolysis temperature and combining regulation and control of impregnation process parameters and selection of slurry types, the consumed time is short, the material permeation effect is improved (permeation is uniform and permeation efficiency is high), and the production period for preparing the biological ceramic-based composite material is shortened.
本发明属于陶瓷及陶瓷基复合材料技术领域，公开了一种用于制备木材衍生的生物态陶瓷基复合材料的木材热解改性方法，该方法是在高温下(250～600℃)对木材块体进行热解改性，即获得具有良好渗透性的浸渍模板，对热解温度进行调控可制得具有不同渗透性的陶瓷基复合材料浸渍模板。该方法操作简单、能制备出孔隙结构完整且渗透效果良好的陶瓷基复合材料浸渍模板，涉及的热解改性设备结构简单但实用性强，能通过控制热解温度、结合浸渍工艺参数的调控、浆料种类的选择来获得渗透效果最佳的陶瓷基复合材料浸渍模板，且耗时较短，本发明提高了材料渗透效果(渗透均匀且渗透效率高)，缩短了制备生物态陶瓷基复合材料生产周期。
