Sandstone-like porcelain exterior wall tile and production method thereof

Abstract

The invention relates to an exterior wall tile and a production method thereof, in particular to a production method of a sandstone-like porcelain exterior wall tile. The production method comprises the following steps: using architecturally applicable materials to press an adobe of the exterior wall tile; adding sandstone particles with a fineness of 20-150 meshes in a suspending agent to prepare a glaze slurry; spraying or coating the glaze slurry on the surface of the adobe; drying, preheating, sintering and cooling the adobe covered with the glaze slurry to obtain a finished product. According to the invention, the whole sandstone-like porcelain exterior wall tile is prepared by only needing one sintering process, thus fuel and energy of sintering one time are saved compared with the prior art, the energy consumption and exhaust discharge of products with same specification are greatly reduced; and the whole exterior wall tile has the decorative effect similar to that of simulation sandstone, thus compared with the prior art, the exterior wall tile disclosed herein has better decorative effect and lower production cost.

Description

technical field [0001] The invention relates to an exterior wall brick and a production process thereof, in particular to a porcelain exterior wall brick imitating a sandstone shape and a production process thereof. Background technique [0002] The existing production process of imitating sandstone exterior wall tiles is: first make the colored grains of imitated sandstone, then mix, press and sinter the colored grains and auxiliary materials to make finished ceramic tiles. Among them, the production of imitation sandstone color particles includes adding colorants such as feldspar, porcelain sand, quartz sand, clay, etc., and water to a certain fineness through ball milling, and then making the mud into particles through high-temperature heat exchange. [0003] The disadvantages of such a process are: [0004] 1. High cost: the imitation sandstone exterior wall brick products are the same outside and inside, which wastes resources and increases the cost of raw materials; ...

AI Technical Summary

Problems solved by technology

[0004] 1. High cost: the imitation sandstone exterior wall brick products are the same outside and inside, which wastes resources and increases the cost of raw materials;

[0005] 2. Not environmentally friendly: heating and drying of color particles and sintering of products, two times of heating waste a lot of fuel, which is not conducive to energy saving and environmental protection;

[0006] 3. Low efficiency: the production process of color particles is original, and the working hours are longer; the two sinterings further prolong the processing time;

[0007] 4. The surface of the product is relatively smooth, and it is easy to form mirror reflection of light, resulting in light pollution; the color particles are unevenly distributed, the color is turbid, there is no layer and three-dimensional effect, and the decorative effect of real sandstone cannot be achieved.
