Refractory fiber and preparation method thereof
The invention relates to the field of refractory fibers, in particular to a refractory fiber and a preparation method thereof.The preparation method comprises the following steps that S1, bauxite, kaolin and vermiculite are taken and ground into powder; s2, adding the vermiculite powder into a sodium chloride solution, heating, slowly dropwise adding tetramethylammonium bromide and a hexadecyl trimethyl ammonium bromide solution into the sodium chloride solution in sequence through a liquid adding device, and carrying out ball milling to obtain refined vermiculite powder; s3, adding water into the bauxite powder, adjusting the pH value to 9-10, carrying out ultrasonic treatment, and carrying out ball milling to obtain refined bauxite powder; s5, adding the refined vermiculite powder, the refined bauxite powder and the refined kaolin powder into a diluent, carrying out ultrasonic treatment, adding aluminum oxide whiskers, an adsorbent, a binding agent and silica sol, and carrying out heating and heat preservation; s6, spinning is carried out at the temperature of 1550-1600 DEG C, and the refractory fiber is obtained. The dripping speed can be controlled through the liquid adding device, and then sufficient reaction of the solution is guaranteed.
本发明涉及耐火纤维领域，特别是一种耐火纤维及其制备方法，包括以下步骤：S1、取铝矾土、高岭土、蛭石研磨成粉末；S2、将蛭石粉末加入氯化钠溶液中后进行加热，同时通过加液装置将四甲基溴化铵和十六烷基三甲基溴化铵溶液依次缓慢的滴加至氯化钠溶液中，进行球磨，得到细化蛭石粉末；S3、向铝矾土粉末中加水，调节pH至9‑10后，进行超声处理，再球磨得到细化铝矾土粉末；S5、将细化蛭石粉末、细化铝矾土粉末和细化高岭土粉末加入稀释剂中，进行超声处理，添加氧化铝晶须、吸附剂、结合剂和硅溶胶，加热保温；S6、在1550‑1600℃下进行纺丝，得到耐火纤维。本发明通过加液装置能够控制滴加速度，进而保证溶液的充分反应。
