Problems solved by technology

[0003] At present, the dry granule materials used in the industry are mainly divided into two types in terms of gloss. One is bright low-temperature dry granule materials, which are mainly used in polishing products with relatively high gloss; the other is matte. At present, matt dry granules are mainly achieved by increasing the formula to achieve matte. Due to the high temperature of the formula, this kind of dry granule materials are prone to rough hand feeling and easy to hide dirt after being applied to ceramic tile products.
Moreover, in the traditional technical scheme, whether it is dry grain material with bright effect or dry grain material with matte effect, its application range is affected by the firing temperature of ceramic tiles, and there is generally a problem that the application range is not wide enough. With the development of ceramic products Diversification of specifications, from 300mm small bricks to 1600mm*3200mm or even larger slates, the existing matt dry granule materials, due to the high firing temperature of large-scale products, are used in large-scale After the product is put on, it is difficult to present its matte effect, and loses the matte characteristics of the matte dry particle itself

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a matte dry particle material and a preparation method thereof. Background technique [0002] The iterative upgrading of surface technology of ceramic products benefits from the continuous updating and upgrading of ceramic materials. Among the materials used in many ceramic products, dry granular materials are undoubtedly a relatively important ceramic application material. Dry granule materials are used in ceramic products to make the product have a more prominent surface texture. On imitation stone, sandstone, cloth grain, wood grain and other products, the surface texture of the product is more realistic than the original material. The dry granule material needs to be fired and melted in advance, and the organic matter and burnable substances in the formula are decomposed at high temperature during the process of making the dry granule, so that the dry granule material has l...
