Description

technical field [0001] The invention relates to the technical field of anti-skid ceramic tiles, in particular to a digital anti-skid inkjet ink, a preparation method and a preparation method of a digital anti-skid ceramic tile. Background technique [0002] In recent years, with the increasing safety awareness of consumers, non-slip ceramic tiles have gradually become the mainstream of the building materials market. At present, non-slip ceramic tiles are mainly made by changing the design of concave and convex molds, adjusting the refractoriness of the decorative glaze layer, and selecting dry particles or special materials. Anti-skid particles and other processes make the surface of the brick into a macro or micro uneven structure, and use this structure and the mechanical bite and friction generated by the sole under pressure to achieve anti-slip effect, compared with ordinary ceramic tile production process : Pressing - drying - glazing - inkjet - firing - edging, these a...

Problems solved by technology

[0003] ⑴ narrow scope of application

For example, the invention patent of publication number CN108249763A discloses a kind of wear-resistant and anti-slip ceramics and its preparation method. By preparing a non-slip ceramic glaze, adjusting the alumina content in the glaze to control the refractoriness of the glaze surface, making the surface of the product rough and applying friction to achieve the anti-slip effect. The disadvantage lies in the difference between conventional and non-slip products with different processes 1. When switching production between different production platforms, it is necessary to continuously adjust the glaze formula to meet the production requirements of the product's anti-skid level. It is impossible to use the same glaze formula on a large scale in the production of different production platforms and different types of ceramic tiles, so the prepared products Its anti-slip effect cannot be guaranteed to be consistent, and its anti-slip coefficient has low controllable precision, which limits the scope of production application

[0004] ⑵Complicated process operation

At present, most of the anti-slip ceramic tile preparation processes at home and abroad use methods such as spraying, spraying or printing dry particles and anti-skid particles to form concave-convex effects on the surface of the base, such as a ceramic tile with a dry glaze decorative surface disclosed in the invention patent of the notification number CN103626523B and Its manufacturing method invention patent, announcement number CN103435369B invention patent discloses the manufacture method of wear-resistant and anti-slip dry grain ceramic tiles, announcement number CN107365080B invention patent discloses the preparation method of anti-skid wear-resistant ceramic tiles, the common point of the technical scheme of these methods is to adopt dry Granules are sprayed, drenched or screen-printed to apply dry granules or non-slip granules to the brick adobe that has completed the pattern decoration. Or a variety of dry granules or anti-slip granules with different properties are used in combination. It is necessary to modify the production line to increase process points, equipment and post manpower to complete the printing and spraying of dry granules or anti-slip granules. This is in line with the company's goal of reducing staff and increasing efficiency. Moreover, dry granules and anti-slip granules are divided into various categories according to different anti-slip properties, and sometimes it is necessary to add posts to manage them. There are various types of dry granules or anti-slip granules, and they are easily affected by human factors when they are frequently used. Leading to production errors and production quality accidents; at the same time, the above-mentioned various dry granules and anti-slip granules are expensive, and a large amount of glue is needed to fix the dry granules to complete the glazed anti-slip decoration. Compared with other types of anti-slip bricks, the production cost An increase of 2.0-3.8 yuan / square, high production costs, high work intensity, and complicated process operations lead to high production costs of this type of anti-slip ceramic tiles, making it difficult for enterprises to produce normally and cost-effectively

[0005] ⑶ Poor production stability

For example, the utility model patent with the notification number CN202108224U discloses a non-slip ceramic floor tile. The upper surface is processed with irregular grooves with a certain depth to achieve the anti-slip effect. The biggest disadvantage is that ceramic tiles with different anti-slip coefficient levels need to be frequently switched and applied with concave-convex molds with different roughness to achieve the anti-skid effect. The roughness is designed and fixed in advance, and the firing systems of different production platforms are different. The anti-slip effect of different batches of anti-slip ceramic tiles prepared cannot be guaranteed to be consistent. Frequent replacement of molds on the one hand may easily cause the production glaze line to fail to operate normally. The phenomenon of empty kiln seriously affects the stability of product production quality, and the excellent rate of product production is generally lower than 90%. On the other hand, changing molds requires a large number of staff to cooperate, and the production efficiency is low, so the continuity of the production line cannot be guaranteed.
