Zirconium silicate composite ceramic roller and preparation method thereof
The invention discloses a zirconium silicate composite ceramic roller and a preparation method thereof. The ceramic roller is prepared by blending and pressing modified zirconium silicate particles and reinforced fibers, wherein the modified zirconium silicate particles are treated by a modifier, so an island-shaped structure is deformed, and a [SiO4] tetrahedron and a [ZrO8] dodecahedron are separated. SiO2-Al2O3 composite oxide has a more stable structure; the [SiO4] tetrahedron and an [AlO6] octahedron form a closely connected spherical structure under a certain condition through control of an additive; the spherical structure is newly compounded with the [ZrO8] dodecahedron to form a ring [ZrO8] dodecahedron island-shaped structure, and the island-shaped structure of zirconium silicate is not changed; and thus, the high temperature resistance, wear resistance and toughness of the roller are improved. A heptadecafluorodecyl base layer on the surface of a reinforced fiber is a hydrophobic layer, so the ceramic roller can be effectively prevented from absorbing moisture in air, and cracks of the ceramic roller during use are avoided.
本发明公开了一种硅酸锆复合陶瓷辊棒及其制备方法，该陶瓷辊棒由改性硅酸锆颗粒和强化纤维共混压制制得，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，强化纤维表面的十七氟癸基层为疏水层，能够有效地防止陶瓷辊棒吸收空气中水分，避免了陶瓷辊棒在使用时出现裂痕。
