Preparation method of viscose-based short fiber thermal insulation composite material
The preparation method comprises the following steps: taking viscose-based carbon fibers as raw materials, chopping the viscose-based carbon fibers, mixing the chopped viscose-based carbon fibers with an auxiliary material A solution, heating the mixed chopped fibers in a vacuum tube furnace to obtain pretreated carbon fibers, mixing an auxiliary material B solution with the pretreated carbon fibers to obtain mixed carbon fibers, putting the mixed carbon fibers into a drying oven, and carrying out cross-linking curing to obtain mixed gel; finally, the mixed gel is subjected to a high-temperature cracking reaction, and the short fiber hard heat preservation composite material is finally prepared and is low in heat conductivity, good in mechanical performance and excellent in density and high-temperature resistance.
本发明以粘胶基碳纤维为原料，将其短切后和辅料A溶液混合，再将混合后的短切纤维放入真空管式炉中加热，得到预处理碳纤维，接着辅料B溶液与预处理碳纤维混合得到混合碳纤维，并将混合碳纤维放入烘箱中交联固化得到混合凝胶，最终将混合凝胶进行高温裂解反应，最终制得短纤维硬质保温复合材料，本发明的粘胶基短纤维保温复合材料，热导率低，具有较好的机械性能，且密度、耐高温性能优异。
