Background
In recent years, with the increasing awareness of safety precautions of consumers, the antiskid ceramic tile gradually becomes the mainstream of the building material market, at present, the antiskid ceramic tile is mainly characterized in that the surface of a tile blank is made into a macroscopic or microscopic uneven structure by changing the design of a concave-convex mould, adjusting the refractoriness of a decorative glaze layer, selecting dry particles or special material antiskid particles and other process modes, the antiskid effect is achieved by utilizing the mechanical engagement effect and the friction effect generated by the structure and a sole under pressure, and compared with the production process of common ceramic tiles: the preparation technology of the antiskid material comprises the following steps of pressing, drying, surface glaze spraying, ink jetting, sintering and edge grinding, and has the following defects:
⑴ the application range is narrow, different types of antiskid ceramic tiles are produced on the same production platform or on different production platforms of the same type of antiskid ceramic tiles, and the produced antiskid coefficients are easily influenced by production process conditions and firing system, so that the prepared antiskid coefficients are inconsistent, and in order to achieve the antiskid effect of the same level, a ceramic manufacturer needs to continuously adjust the production process to adapt to the antiskid coefficient requirement of the antiskid ceramic tiles.
⑵, the process operation is complex, most of the current preparation processes of the anti-skid ceramic tiles at home and abroad adopt the modes of spraying, spraying or printing dry particles, anti-skid particles and the like to form concave-convex effects on blank surfaces, for example, the ceramic tiles with dry glaze decoration surfaces disclosed in the patent publication No. CN103626523B and the manufacturing method thereof, the patent publication No. CN103435369B and the patent publication No. CN107365080B disclose the manufacturing method of the anti-skid and wear-resistant ceramic tiles, the technical scheme of the methods is that the dry particles are distributed on the tile blanks subjected to pattern decoration by the modes of spraying, spraying or silk screen printing, the technical scheme is characterized in that the dry particles are complex in operation, one or a plurality of dry particles with different performances or anti-skid particles are mixed for use according to different anti-skid effects and different production platforms, process points, equipment and posts need to be improved, the hands of workers and workers need to improve production lines, the printing and spraying of the anti-skid particles or the anti-skid particles are required to be changed frequently, the anti-skid particles are distributed and applied to the production process points, the dry particles and the equipment and the production cost of the dry particles is increased by the high-skid-resistant particles, the cost of the dry particle production process is increased, the cost of the dry particle is increased, the cost of the dry particle is increased when the dry particle is increased, the cost of the dry particle is increased.
⑶ production stability is poor, in the preparation process of the antiskid ceramic tile, the surface of the green brick is formed into a rugged structure by utilizing the mold design in the pressing process to improve the antiskid effect of the ceramic tile, for example, the utility model with the publication number of CN202108224U discloses an antiskid ceramic floor tile, the adopted process steps are that the irregular mold is manufactured, dried, the surface glaze is sprayed, the pattern is decorated, the ceramic tile is fired and the edge is grinded, the technical proposal is that the antiskid effect is achieved by processing the irregular groove with certain depth on the upper surface of the ceramic tile, the biggest disadvantage is that the antiskid effect of the ceramic tile with different antiskid coefficient grades is achieved by frequently converting and using the rugged molds with different roughness degrees, the roughness degree of the rugged molds is designed and fixed in advance, but the firing systems of different production platforms are different, the antiskid effect of the prepared antiskid ceramic tile with different batches cannot be ensured to be consistent, the frequent replacement of the molds can not cause the normal operation of the production glaze line to cause the empty kiln phenomenon easily, the production quality stability of the product is seriously affected, the rate of the production and the equal to be generally lower than 90%, on the other hand, the synergistic replacement of the mold needs to ensure the excellent operation efficiency of the production line.
