High-hole thin-wall cordierite carrier with good protectiveness and preparation method thereof
The invention discloses a high-hole thin-wall cordierite carrier with good protectiveness and a preparation method thereof.The carrier comprises carrier raw materials and ingredients, and the carrier raw materials comprise, by weight, 28%-35% of spherical flaky mixed talc, 13%-16% of spherical silicon oxide, 16%-19% of flaky aluminum oxide, 8% of fibrous boehmite and 8% of fibrous kaolin; according to the invention, by selecting the morphology and stacking arrangement mode of the raw materials, the internal resistance of the pug under stress slippage is improved, the deformation amount is reduced, and meanwhile, the extrusion performance is improved by introducing the high-temperature-resistant inorganic powder with relatively large particle size and consistent or approximate expansion coefficient.
本发明公开了一种保护性好的高孔薄壁堇青石载体及其制备方法，载体包括载体原料和配料，载体原料按照重量份数包括28％～35％的球状片状混合滑石，13～16％的球状氧化硅，16～19％的片状氧化铝，8％的纤维状一水软铝石，8％的纤维状高岭土，15～30％的无机填料，通过对原料形貌、堆积排列方式进行选取，提高了泥料受力滑移下的内部阻力，减少了变形量，同时通过引入粒度较粗的膨胀系数一致或接近的耐高温无机粉料，提高了挤出性能。
