Embodiment 1

[0032] A method for preparing a digital metal surface rock plate, comprising the following steps:

[0033] The green body is fed into the ceramic digital printer, and the bottom glaze is printed by inkjet (the application amount is 150g / m 2 ), digital metal glaze (application amount is 200g / m 2 );

[0034] Send it into a kiln for sintering at 1450°C for 40 minutes, and cool to obtain the digital metal surface rock plate.

[0035] The viscosity of the digital metal glaze is 102mPa·s (at 25°C).

[0036] The digital metal surface slab is prepared by inkjet printing bottom glaze and digital metal glaze on the body, and sintered. The metal surface is formed by printing digital metal glaze. By controlling the digital metal glaze The viscosity of the material is 60~150mPa·s (25°C), which can be evenly coated and leveled during the printing process, and will not be deformed during the sintering process, so it has good flatness and density.

[0037] The bottom glaze is prepared fro...

Abstract

The invention belongs to the technical field of rock plates, and particularly discloses a preparation method of a digital metal surface rock plate, which comprises the following steps: feeding a green body into a ceramic digital printer, and printing ground glaze and digital metal glaze through ink-jet printing; and sintering in a kiln, and cooling to obtain the digital metal surface rock plate. And the viscosity of the digital metal glaze material is 60 to 150 mPa.s. The digital metal surface rock plate is prepared by ink-jet printing of the ground coat and the digital metal glaze on the green body and sintering, the digital metal glaze is printed to form a metal surface, and the digital metal glaze can be uniformly coated and leveled in the printing process by controlling the viscosity of the digital metal glaze to be 60-150mPa. S (25 DEG C), so that the digital metal glaze can be uniformly coated and leveled, and the digital metal glaze can be uniformly coated and leveled in the printing process. And deformation cannot occur in the sintering process, so that good flatness and compactness are achieved.

Description

technical field [0001] The invention relates to the technical field of rock slabs, in particular to a method for preparing a digital metal surface rock slab. Background technique [0002] As a new material emerging in the past two years, slate can replace stone, glass, plastic panels, quartz stone, artificial stone, etc. due to its large size, thinness, and good secondary processing performance. It is widely used in various countertops, large background, cabinet customization and other fields. [0003] The proportion of digital technology in the field of ceramics and rock slab processing is gradually increasing. In the field of ceramics and rock slab processing, the superiority of digital technology is becoming more and more prominent. At present, the strength of rock slabs printed by digital technology is generally low. Therefore, how to Printing rock slabs with good strength through digital technology has become a technical problem to be solved urgently by those skilled i...
