Abstract

The invention discloses a granite-speckle-imitated ceramic exterior wall brick and a preparation method thereof. The preparation method comprises the following steps: preparing color particles of different colors, different sizes and different shapes, and mixing the particles; adding an environmental protection additive to achieve mixing of different color particles without being compatible; spraying the mixed color particles on a ceramic exterior wall brick body; performing fusion spreading on the low-melting components of the colored particles during a firing process, performing natural fusion on the edges of the different color particles, leaving the inorganic color particles of different sizes, different shapes and unevenness on the ceramic tile, and obtaining the granite-speckle-imitated ceramic exterior wall brick with a uneven grainy surface. The performance of the ceramic exterior wall brick is higher than the relevant national standards, which not only helps to reduce the over-exploitation of granite stone in the construction industry, also provides consumers with realistic granite-speckle-imitated ceramic exterior wall brick, and meets the needs of consumers for granite decorative effects.

Description

technical field [0001] The invention relates to a ceramic outer wall tile, in particular to a ceramic outer wall tile imitating granite patterns and a preparation method thereof, and belongs to the field of building ceramic materials. Background technique [0002] With the continuous improvement of people's living standards in our country, consumers have higher and higher requirements for building decoration materials. Especially in the field of building exterior walls, ordinary silica brick walls or cement walls can no longer meet the aesthetic needs of consumers. In the context of the rapid development of the building ceramics industry, consumers are more and more keen on the exterior walls of stone or imitation stone. In particular, granite stone and plates or coatings with granite patterns are more and more popular with consumers. Natural granite is a non-renewable stone, which is expensive and difficult to process due to its high hardness. Therefore, natural granite ...
