Preparation method of large-size ultrathin high-strength ceramic board
The invention discloses a preparation method of a large-size ultrathin high-strength ceramic board. The preparation method comprises the following steps of 1, preparing a ceramic base material; 2, preparing ceramic base slurry; 3, preparing a chopped fiber reinforced felt; 4, preparing a prepreg; 5, preparing a ceramic tile blank; 6, drying and glazing a green body; 7, sintering. In the preparation process, the chopped fiber felt is adopted as a reinforcing material, and a prepreg cold-pressing blank method is designed according to the characteristics of the fiber felt. The strength and rigidity of the blank can be effectively improved, and the thickness of the blank is reduced. The sintering shrinkage rate of a ceramic product can be reduced, cracking and deformation of the ceramic product are limited, and basic guarantee is provided for preparation of large-size ceramic tiles. The chopped fiber felt is adopted and can play a supporting role in the blank manufacturing process, the large-size blank can be better manufactured, and the problem in the prior art that the pressed blank is cracked in the conventional blank manufacturing process is solved.
本发明公开了一种大尺寸超薄高强度陶瓷大板的制备方法，包括以下步骤：步骤一：陶瓷基料的配制；步骤二：陶瓷基浆料的制备；步骤三：短切纤维增强毡的制备；步骤四：预浸料的制备；步骤五：瓷砖胚体的制备；步骤六：坯体干燥与上釉；步骤七：烧结。本发明的制备过程中采用了短切纤维毡作为增强材料，并且根据纤维毡的特性，设计预浸料冷压制胚的方法；不仅可以有效提高胚体的强度和刚度，降低胚体厚度；还可以降低陶瓷制品烧结收缩率，限制其开裂和变形，为大尺寸瓷砖制备提供基本保障。本发明中采用了短切纤维毡，在制坯过程中可以作为一个支撑作用，可以更好的制备大尺寸的坯体，坚决目前常规的制坯过程中压坯出现开裂的问题。
