The invention discloses a high-temperature-resistant roller rod and a preparation method thereof. The high-temperature-resistant roller rod is prepared by blending and pressing modified reinforced particles and modified zirconium silicate particles, the modified zirconium silicate particles are treated by a modifier, so that an island-shaped structure deforms, [SiO4] tetrahedrons and [ZrO8] dodecahedrons are separated, SiO2-Al2O3 composite oxide has a more stable structure, and through control of an additive, the [SiO4] tetrahedrons, and the [AlO6] octahedron form a closely connected spherical structure under a certain condition, the spherical structure is newly compounded with the [ZrO8] dodecahedron to form a ring [ZrO8] dodecahedron island-shaped structure, the island-shaped structure of zirconium silicate is not changed, the high temperature resistance, wear resistance and toughness of the roller rod are improved, the modified reinforced particles are prepared, the toughness of the high-temperature-resistant roller rod is further improved, and the service life of the roller rod is prolonged.
本发明公开了一种耐高温辊棒及其制备方法，通过改性增强颗粒和改性硅酸锆颗粒共混压制制得，改性硅酸锆颗粒通过改性剂处理，使岛状结构变形，[SiO4]四面体和[ZrO8]十二面体脱离，SiO2‑Al2O3复合氧化物具有更稳定的结构，通过添加剂的控制，使[SiO4]四面体，[AlO6]八面体在一定条件下形成紧密连接的球形结构，这种球形结构与[ZrO8]十二面体重新复合，形成环[ZrO8]十二面体岛状结构，硅酸锆的岛状结构不变，增加了辊棒的耐高温性、耐磨性、韧性，并制备了改性增强颗粒，进一步的提升了耐高温辊棒韧性，使得辊棒的使用寿命提升。
