| description | The invention provides basalt nanosheet-based high-temperature-resistant and ultraviolet-resistant insulation paper capable of being recycled for multiple times and a preparation method thereof.The preparation method comprises the steps that para-aramid fibers are ground in deionized water to obtain fibrillated para-aramid fibers, and the fibrillated para-aramid fibers are dispersed in a potassium hydroxide solution; adding a dimethyl sulfoxide solution at a preset temperature for reaction to obtain an ANF/DMSO mixed solution, and then adding a protonation donor solvent for reaction to obtain aramid nanofibers; the preparation method comprises the following steps: reacting basalt nanosheets with a polyvinylpyrrolidone solution to obtain basalt nanosheets with carbonyl groups on the surfaces, mixing the basalt nanosheets with the carbonyl groups on the surfaces with aramid nanofibers, carrying out suction filtration to form paper, and drying to obtain the basalt nanosheet-based high-temperature-resistant and u |
