The invention relates to the technical field of building materials, and provides a one-time firing method of a decorative wallboard, which comprises the following steps: and (4) carrying out bottom layer decoration material distribution in the sagger to form a decoration layer, wherein the thickness of the decoration layer is 3-5 mm. And (3) distributing a first transition layer on the decorative layer to form the first transition layer, wherein the thickness of the first transition layer is 1.5-2.5 mm. And distributing the material to the first transition layer to form a second transition layer, wherein the thickness of the second transition layer is 2.5-3.5 mm. And distributing foaming powder to the second transition layer to form a foaming powder layer, wherein the thickness of the foaming layer is 44-50 mm. And sintering after the material distribution is finished to obtain a primary wallboard, wherein the sintering temperature is 1170-1200 ℃, and the sintering time is more than or equal to 10 hours. The method can be used for firing the decorative wallboard at one time, and the quality of the manufactured decorative wallboard is good. The invention provides a decorative wallboard, which is prepared by the firing method provided by the invention. The decorative wall board can be applied to indoor wall decoration. |
