Preparation method of toughened building ceramic product and ceramic product
The invention discloses a preparation method of a toughened building ceramic product. The preparation method comprises the following steps: laying low-shrinkage material powder on the surface of a building ceramic green body, carrying out dry pressing, and sintering. In addition, the invention also discloses a ceramic product prepared by the preparation method of the toughtened building ceramic product. The shrinkage of the ceramic body is counteracted by the low-shrinkage material so that the shrinkage of the surface layer of the ceramic is less than that of the base body in the shrinkage process, the ceramic is dragged by the shrinkage of the base body to form surface layer pressure stress, and the aim of remarkably improving the breaking strength of the ceramic product is further achieved; meanwhile, the preparation of the building ceramic thin plate is also facilitated so that the use amount of raw materials for producing green bodies can be reduced, high-quality ceramic raw material resources are saved, the production cost is reduced, and energy conservation and emission reduction are facilitated, thereby playing an important role in sustainable development of the building ceramic industry, acceleration of ecological civilization construction and realization of green development.
本发明公开了一种钢化建筑陶瓷制品的制备方法，通过在建筑陶瓷坯体表面铺设低收缩材料粉体，经干压成型、烧结而成。此外，还公开了利用上述钢化建筑陶瓷制品的制备方法制得的陶瓷制品。本发明通过低收缩材料来抵消陶瓷坯体的收缩，使得陶瓷在收缩过程中表层收缩少于基体的收缩，从而被基体的收缩牵扯而形成表层压应力，进而达到显著提高陶瓷制品抗折强度的目的；同时，也有助于建筑陶瓷薄板的制备，从而能够减少生产坯体原料的使用量、节约优质陶瓷原料资源，降低生产成本，有利于节能减排，从而为建筑陶瓷行业的可持续发展，以及加快生态文明建设、实现绿色发展发挥重要作用。
