Description

Technical Field

[0001] This invention belongs to the field of ceramic technology, and specifically relates to a wear-resistant and corrosion-resistant ceramic brick and its preparation method. Background Technology

[0002] Ceramic tiles, as a building decoration material, are widely used in indoor and outdoor walls, floors, industrial floors and other fields. Their wear resistance and corrosion resistance are key indicators that determine their service life.

[0003] The preparation of traditional ceramic tiles mainly relies on natural mineral raw materials (such as kaolin and feldspar) and conventional sintering processes. However, due to limitations in raw material formulation design and process parameters, traditional ceramic tiles still suffer from the following problems: Insufficient wear resistance: The Mohs hardness of traditional ceramic tiles is typically 4-5, and the surface glassy phase is prone to scratches under long-term friction; Poor corrosion resistance: Traditional ceramic tiles are easily chemically eroded in corrosive environments such as acids and alkalis, leading to surface powdering and peeling, affecting their service life. Currently, most methods aim to improve the wear resistance of ceramic tiles by directly adding inorganic reinforcing powders (such as alumina and silicon carbide), but these powder materials tend to agglomerate and disperse unevenly during practical applications, resulting in minimal performance improvement.

[0004] Therefore, it is necessary to develop a wear-resistant and corrosion-resistant ceramic tile. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention provides a wear-resistant and corrosion-resistant ceramic tile and a method for preparing the same, wherein the ceramic tile of the present invention achieves a comprehensive optimization of both high wear resistance and high corrosion resistance.

[0006] In a first aspect, the present invention provides a wear-resistant and corrosion-resistant ceramic tile, the wear-resistant and corrosion-resistant ceramic tile comprising a body layer and a glaze layer;

[0007] The raw materials for preparing the glaze layer include modified graphene oxide and modified basalt fiber;

[0008] The modified graphene oxide is prepared by a method including the following steps:

[0009] 1) Mix nano-alumina, nano-silica, silane coupling agent with organic solution, stir, filter, and obtain solid;

[0010] 2) The solid and graphene oxide nanosheets are mixed with an organic solution, heated, stirred, and dried to obtain the modified graphene oxide;

[0011] The modified basalt fiber is prepared by a method including the following steps:

[0012] a) Basalt fiber, dopamine hydrochloride and tris(hydroxymethyl)aminomethane buffer are mixed, heated, stirred and dried to obtain activated basalt fiber;

[0013] b) Mix silicon nitride, dopamine hydrochloride and tris(hydroxymethyl)aminomethane buffer, stir, and dry to obtain activated silicon nitride;

[0014] c) The activated silicon nitride, the activated basalt fiber, the tris(hydroxymethyl)aminomethane buffer solution and the dispersant are mixed, stirred and dried to obtain modified basalt fiber.

[0015] Specifically, this invention introduces modified graphene oxide into the glaze layer. A silane coupling agent reacts with the hydroxyl groups on the surface of nano-alumina and nano-silica, allowing the silane coupling agent to be grafted onto the surface of the nano-alumina and nano-silica. This allows the silane coupling agent to react with the hydroxyl and carboxyl groups on the surface of the graphene oxide nanosheets, resulting in the uniform deposition of nano-alumina and nano-silica on the surface of the graphene oxide nanosheets. During the subsequent firing process to form the glaze layer, the nano-alumina and nano-silica undergo a solid-phase reaction to generate a mullite crystal structure with excellent mechanical properties, which is uniformly distributed on the surface of the graphene oxide nanosheets. Furthermore, the graphene oxide nanosheets have a two-dimensional sheet structure, allowing them to be uniformly dispersed in the glaze layer, forming a dense physical barrier. This effectively blocks the penetration of corrosive media (such as acid, alkali, and salt solutions) and slows down the corrosion process. Under the combined effect of the uniformly distributed mullite crystal structure and graphene oxide, the ceramic tile possesses both excellent mechanical properties and corrosion resistance.

[0016] Specifically, this invention also introduces modified basalt fibers into the glaze layer. Utilizing the principle that dopamine can self-polymerize to form polydopamine under alkaline conditions, polydopamine microspheres are grown on the surfaces of basalt fibers and silicon nitride after activation of basalt fibers and silicon nitride respectively. This improves the adhesion and activity of the basalt fiber and silicon nitride surfaces, making it easy for silicon nitride to adhere to the basalt fiber surface. While increasing the surface roughness of basalt fibers, active groups such as hydroxyl groups are introduced, enhancing the interfacial bonding between modified basalt fibers and other raw materials. At the same time, silicon nitride itself has high hardness and self-lubricating properties, effectively improving the hardness and wear resistance of ceramic tiles. Through the combined effect of modified basalt fibers and modified graphene oxide, the mechanical properties (high hardness, wear resistance) and corrosion resistance of ceramic tiles are significantly improved.

[0081] Comparative Example 1

[0082] The only difference from Example 1 is that the modified graphene oxide was replaced in equal amounts with a mixture of nano-alumina, nano-silica and graphene oxide nanosheets (the mass ratio of nano-alumina, nano-silica and graphene oxide nanosheets was 1:1.5:0.15), while the other conditions remained the same as in Example 1.

[0083] Comparative Example 2

[0084] The only difference from Example 1 is that no nano-silica was added to the modified graphene oxide in Comparative Example 2 (the amount of nano-alumina added was adjusted to 2.5g), and the other conditions were the same as in Example 1.

[0085] Comparative Example 3

[0086] The only difference from Example 1 is that in Comparative Example 3, the modified basalt fiber was replaced with a mixture of 8g basalt fiber and 1g silicon nitride, while the other conditions remained the same as in Example 1.

[0087] Comparative Example 4

[0088] The only difference from Example 1 is that Comparative Example 4 lacks modified graphene oxide, and the amount of modified basalt fiber added is increased to 6 parts, while the other conditions are the same as those in Example 1.

[0089] Comparative Example 5

[0090] The only difference from Example 1 is that Comparative Example 5 lacks modified basalt fiber, and the amount of modified graphene oxide added is increased to 6 parts, while the other conditions are the same as those in Example 1.

[0091] Product performance testing

[0092] The ceramic tile samples prepared in Examples 1-3 and Comparative Examples 1-5 were subjected to Mohs hardness, abrasion resistance, and corrosion resistance tests. Specifically, abrasion resistance was tested according to GB / T 3810.7-2016 "Determination of Abrasion Resistance of Glazed Tile Surfaces"; corrosion resistance was tested according to GB / T 3810.13-2016 "Determination of Chemical Corrosion Resistance".

[0093] The test results are shown in Table 1.

[0094] Table 1

[0095] Sample group Mohs hardness abrasion resistance Corrosion resistance Example 1 7.0 Level 4, 12000 RPM GLA Example 2 7.0 Level 4, 12000 RPM GLA Example 3 7.0 Level 4, 12000 RPM GLA Comparative Example 1 5.5 Level 4, 2100 RPM GLB Comparative Example 2 5.0 Level 4, 2100 RPM GLB Comparative Example 3 6.0 Level 4, 6000 RPM GLA Comparative Example 4 5.0 Level 4, 2100 RPM GLB Comparative Example 5 5.5 Level 4, 2100 RPM GLB

[0096] As shown in Table 1, the ceramic tile samples prepared in Examples 1-3 have a Mohs hardness of up to 7.0 and a wear resistance of up to level 4 at 12,000 revolutions, exhibiting excellent wear resistance and corrosion resistance.

[0097] Compared to Example 1, Comparative Example 1, due to the direct addition of nano-alumina and nano-silica, tends to agglomerate, resulting in a significant reduction in hardness, wear resistance, and corrosion resistance.

[0098] Compared to Example 1, Comparative Example 2 lacks nano-silica, which prevents it from forming a mullite crystal structure with nano-alumina, resulting in a significant reduction in hardness, wear resistance, and corrosion resistance.

[0099] Compared to Example 1, Comparative Example 3 directly added basalt fiber, which has a smooth surface, resulting in weaker bonding between the basalt fiber and the raw material, leading to relatively poor hardness and wear resistance.

[0100] Compared to Example 1, Comparative Examples 4 and 5 showed significantly reduced hardness, wear resistance, and corrosion resistance due to the lack of modified graphene oxide and modified basalt fiber, respectively.
