Abstract

The invention discloses a printing method for the glazed surface of building materials, which belongs to the technical field of building materials. The printing method for the glazed surface of building materials includes the following steps: (1), preparing printing slurry; (2), pouring the slurry into In the light-curing 3D printer barrel, according to the digital model, the slurry is sprayed layer by layer on the X-Y surface of the green body layer through preset printing parameters to form a glaze layer, and the printing is completed. The printing paste is prepared from the following raw materials in parts by weight: 65-75 parts of ceramic powder, 10-20 parts of frit, 10-20 parts of photosensitive resin, 1-3 parts of surfactant, 0.5-1.5 parts of photoinitiated agent. The printing method for the glazed surface of building materials optimizes the printing slurry, reduces the viscosity of the printing slurry, optimizes the rheological properties, and at the same time modifies aluminum nitride and calcium phosphate to obtain a material with good flexural strength, dense ceramics.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a printing method for glazed surfaces of building materials. Background technique [0002] 3D printing technology is rapid prototyping technology, also known as additive manufacturing. It is based on a digital model, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. 3D printing technology combines cutting-edge technologies in multiple fields such as material technology, digital modeling, and information processing, breaking the traditional thinking mode of processing. [0003] Studying the rheological properties of surface ceramic paste is crucial to the operability of 3D printing, and it will also affect the density and mechanical properties of printed ceramic products. [0004] CN105198414A discloses a ceramic material for 3D printing, comprising the following components by weight: 50-150 parts by weight of...
