摘要/Abstract

摘要： 建筑陶瓷薄板作为一种轻薄、低能耗的家装产品而逐渐成为市场的发展潮流,如何进一步对其实现减薄和增强也成为研究的热点。本文以建筑陶瓷高铝粉料为基体,设计二次球磨法并引入长径比为70~82的氧化锆纤维作为增强相,借助KH570表面改性剂改善纤维/基体(F/M)的界面结合,制备了氧化锆纤维增强超薄陶瓷板。研究表明,采用二次球磨工艺可以有效实现纤维在基体中的分散,当氧化锆纤维的掺杂量为3%(质量分数)时,超薄陶瓷板的弯曲强度可达到106.4 MPa,相较于空白样(96.8 MPa)提升了9.92%。在高温固相反应中,陶瓷熔融相的Na⁺、K⁺对氧化锆晶格的渗透作用会引起四方晶系氧化锆相向锆英石相的转变,四方晶系氧化锆相内部存在微裂纹拓展、颗粒弥漫增强、“纤维桥联-断裂拔出”等多种良性增强机制。

Abstract: As a kind of light, thin and low energy consumption home decoration products, building ceramic sheet has gradually become the development trend of the market and how to further thinning and strengthen it has also become a research hotspot. In this article, the building ceramics powder with high aluminum content was used as the matrix, a secondary ball milling method was designed and the zirconia fiber with the length-diameter ratio of 70 to 82 was used as the reinforcing phase into the matrix. With the help of KH570 which was as the surface modifier to improve the interface bonding of fiber/matrix (F/M), the zirconia fiber reinforced ultra-thin ceramic plate was prepared. The results show that the secondary ball milling process can effectively influence the fiber dispersion in the matrix. When the doping amount of zirconia fiber is 3% (by mass), the bending strength of the ultra-thin ceramic plate reaches 106.4 MPa which is 9.92% higher than the blank sample of 96.8 MPa. In the high temperature solid phase reaction, the permeation of Na⁺ and K⁺ in the ceramic melt phase to the zirconia lattice causes the transformation of the tetragonal zirconia phase to the zirconite phase. Many positive strengthening mechanisms in the tetragonal zirconia phase, such as micro-crack expansion, particle diffusion enhancement and fiber bridge-pull out, may be responsible for inhibiting cracks’ propagation.

Key words: building ceramic sheet, secondary ball milling process, dispersity, zirconia fiber, strengthening mechanism
