Description

TECHNICAL FIELD

[0001] The present application relates to the field of ceramic tile anti-fouling treatment, in particular to an anti-fouling treatment method and system applied to the surface of ceramic tile and anti-fouling ceramic tile. BACKGROUND

[0002] In the process of ceramic tile preparation, in order to improve the surface anti-fouling performance, after the firing step of ceramic tile, after edge grinding and polishing, the "super bright" waxing process or anti-fouling waxing is generally used. The millstone of the two processes uses a high-speed motor of 1000-3000 rpm to quickly polish the anti-fouling coating on the surface of the ceramic tile, forming an organic protective film layer on the surface. The technical inertia of the traditional waxing anti-fouling technology has technical defects that cannot be ignored: No matter how the anti-fouling coating is iterated or the thickness of the organic coating is increased, as long as the film is still formed on the surface of the ceramic tile, the hardness, wear resistance, chemical inertia and optical stability of the ceramic tile glaze are much higher than those of the anti-fouling coating (the hardness of the existing coating is usually 3H-6H, and it is easy to age and yellow), after being put into use, human walking and external friction on the anti-fouling coating can easily cause it to wear out quickly, and the anti-fouling function will be lost, which cannot be durable, equivalent to a "sacrifice layer"; secondly, on the appearance of the ceramic tile, the surface organic film layer gives the ceramic tile a plastic or wax feeling, covering the natural beauty of the ceramic tile glaze, and the organic film layer further causes the gloss of the ceramic tile surface to decay and the texture to deteriorate after wear and aging, which is difficult to meet the natural, warm and durable appearance requirements of high-end ceramic tiles pursued by customers. SUMMARY

[0003] The main purpose of the present application is to propose an anti-fouling treatment method applied to the surface of ceramic tile, which adopts a completely different technical route from the traditional waxing anti-fouling, and combines the properties of ceramic tile glaze with a specific anti-fouling treatment method, overcoming the technical defects of the existing anti-fouling coating, such as not durable, and the appearance of ceramic tile cannot meet the requirements of high-end ceramic tile.

[0004] The secondary purpose of the present application is to propose an anti-fouling treatment system for implementing the aforementioned anti-fouling treatment method.

[0005] The third purpose of the present application is to propose an anti-fouling ceramic tile having a specific structure after the aforementioned anti-fouling treatment method.

[0006] To achieve the above purpose, the present application proposes an anti-fouling treatment method applied to the surface of ceramic tile, comprising the following steps: S1. Penetration anti-fouling treatment: applying a penetration anti-fouling agent that can penetrate into the pores of the glaze on the polished ceramic tile glaze; S2. Curing and sealing treatment: a curing and sealing agent is applied on the tile surface treated in step S1, the penetrating anti-fouling agent reacts with the curing and sealing agent to form a cured anti-fouling material, the anti-fouling material fills the glaze pores and forms an anti-fouling layer on the glaze surface; S3. Selective removal: a cleaning and softening agent is applied on the tile surface treated in step S2, the anti-fouling layer is softened, and then the anti-fouling layer is mechanically removed to expose the glaze surface, while the anti-fouling material filled in the glaze pores is retained.

[0007] Generally, technicians are accustomed to the technical paradigm of traditional wax polishing anti-fouling route, and it is difficult for them to break away from the thinking inertia that "anti-fouling treatment is equal to adding an anti-fouling film layer on the tile surface". The focus of the present application is to overcome the traditional thinking inertia. Since the anti-fouling film layer formed by traditional wax polishing anti-fouling is easily damaged during use, the hardness, wear resistance, chemical inertness and optical stability of the dense inorganic silicate glass phase formed by sintering at a temperature above 1000 degrees Celsius are significantly better than the corresponding properties of the anti-fouling film layer. Can a new anti-fouling treatment method be used to combine the properties of the tile glaze and improve the anti-fouling performance and durability of the tile glaze, while also considering the aesthetic effect of high-end tiles? This is the main technical problem solved by the present application.

[0008] The present application discards the technical paradigm of "adding an organic anti-fouling film layer on the tile surface" used in the traditional wax polishing anti-fouling route, and innovatively combines the properties of the tile glaze and a specific anti-fouling treatment method to create a new technical paradigm. The present application applies a penetrating anti-fouling agent and a curing and sealing agent on the tile glaze in steps, the penetrating anti-fouling agent penetrates into the open pores of the glaze layer, and then reacts with the curing and sealing agent to form an anti-fouling material. The anti-fouling material fills the glaze pores and forms an anti-fouling layer on the glaze surface. Then, by softening the tile surface, the anti-fouling layer on the glaze surface is selectively removed by mechanical removal, so that the glaze surface is completely exposed, and the anti-fouling material in the glaze pores is selectively retained. Since the anti-fouling material is hidden inside the pores, it is almost not affected and damaged by external forces after being put into use, and the anti-fouling performance is long-lasting and reliable. Compared with the existing method of attaching an organic film layer to the glaze, the present application completely exposes the glaze, and the tile surface presents the real and original gloss and touch of the glaze. The glaze performance is durable, and meets the pursuit of natural and warm texture and lasting beauty in the high-end ceramic market. There is no situation like the destruction of the organic film layer after long-term use, which leads to a decrease in aesthetic and tile surface performance.

[0009] Preferably, the penetration antifouling agent comprises, by weight percentage, fluorosilicon modified acrylate copolymer emulsion 30-50%, nano-silica dispersion pretreated by silane coupling agent KH-560 10-20%, acetylenic diol non-ionic surfactant 0.5-1.5%, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate 2-4%, and deionized water 23-57%. The solidification pore sealing agent comprises, by weight percentage, epoxy-acrylic hybrid emulsion 25-40%, hydrophilic modified polyether amine curing agent 5-10%, silane modified sheet mica powder 15-25%, steric alcohol amine pH regulator 0.1-0.5%, and deionized water 23-54%. Preferably, the steric alcohol amine pH regulator is AMP-95.

[0010] The fluorosilicon modified acrylate copolymer emulsion in the penetration antifouling agent provides carboxyl (-OH) derived from the acrylate copolymer chain as one of the most effective reaction sites, the side groups from the copolymer chain or the silicon hydroxyl (Si-OH) on the surface of the nano-silica dispersion pretreated by silane coupling agent KH-560 provides a source of hydroxyl (-OH), and the silane coupling agent KH-560 provides an epoxy group; the epoxy-acrylic hybrid emulsion in the solidification pore sealing agent provides an epoxy group as a core reaction group, the hydrophilic modified polyether amine curing agent provides an amine group (-NH2) source as the main functional group for ring-opening addition curing reaction with the epoxy group. The solidification pore sealing agent is used in a just-in-time manner, or the hydrophilic modified polyether amine curing agent is simultaneously added dropwise during step S2. The penetration antifouling agent and the solidification pore sealing agent cooperate to undergo curing and hybridization in the pores. The curing reactions mainly involve neutralization and amidation between the amine group in the solidification pore sealing agent and the carboxyl group in the penetration antifouling agent, as well as ring-opening polymerization with the epoxy groups carried by the penetration antifouling agent and the solidification pore sealing agent themselves. These reactions form a dense three-dimensional crosslinked network in the pores, chemically bonding the flexible antifouling segment of the penetration antifouling agent with the rigid epoxy segment of the solidification pore sealing agent. The main hybridization reactions include the nano-silica pretreated by KH-560 in the penetration antifouling agent, the surface of which has been entangled or reacted with the long organic chains of the silane coupling agent. Meanwhile, the other end of the silane coupling agent (siloxane part) forms Si-O-Si covalent bonds or hydrogen bonds with nano-SiO2 and the ceramic tile pore wall (mainly composed of silicates). This enables the inorganic nano-filler and the inorganic ceramic matrix to be firmly combined with the organic resin network through the organic silane bridge, achieving "organic-inorganic hybridization". Finally, a non-simple physical filling is formed in the pores, which is an antifouling layer with an organic crosslinked network as the continuous phase, chemically bonded nano-silica as the reinforcing phase, and strong anchoring with the ceramic pore wall through the silane bridge.

[0011] The silane coupling agent KH-560 has a bifunctional group, the alkoxyl group at one end condenses with the hydroxyl group on the surface of the nano-silica after hydrolysis to form a covalent bond; the other end of the organic long chain (such as epoxy group) is physically entangled or chemically reacted with the polymer chain of the fluorosilicon modified acrylate. Through the foregoing treatment, a "molecular bridge" is built between the inorganic nano-filler and the organic resin matrix, greatly improving the dispersibility of the nanoparticles in the resin and the interfacial bonding force. The final filling into the pores is not a loose mixture, but an organic-inorganic hybrid reinforcing network, which significantly improves the compression resistance, wear resistance and bonding strength. In the curing and sealing agent, the silane modified mica powder and the epoxy-acrylic hybrid, the epoxy resin provides high adhesion and chemical resistance, and the acrylic resin provides flexibility and fast drying. Both form an interpenetrating network or core-shell structure through hybridization, and the performance is complementary. The hydrophilic modified polyether amine curing agent undergoes ring-opening addition reaction with the epoxy group to form a dense three-dimensional crosslinked network, and this network also reacts with the active groups (such as carboxyl groups from silane or acrylic acid) enriched in the penetrating stain-proof agent to achieve interlayer chemical bonding. The silane modified mica powder has better compatibility with the hybrid resin on the surface of the lamellar layer, can be arranged in parallel at the pore opening, and forms a dense physical barrier like "tiles", together with the chemical crosslinked network of the resin, to form a double sealing on the physical sealing and chemical reaction crosslinking.

[0012] Further preferably, the cleaning softener comprises, in terms of weight percentage: alkyl polyglycoside 8-15%, sodium lauroyl glutamate 3-7%, dipropylene glycol butyl ether 5-10%, organic amine pH adjuster 1-2%, HASE thickening agent 0.2-0.8%, and deionized water 66-82%. Through the cleaning softener in the above formula, all continuous organic coatings formed on the surface of the ceramic tile glaze by the aforementioned penetrating stain-proof agent and curing and sealing agent are removed, while the reaction products of the penetrating stain-proof agent and the curing and sealing agent that have penetrated and filled and cured inside the pores on the surface of the ceramic tile glaze are preserved and protected, and a specific nylon brush wheel is used, so that the final fired glaze of the ceramic tile is completely exposed.

[0013] Preferably, in step S1, the penetrating stain-proof agent is first added dropwise on the surface of the ceramic tile, and then the penetrating stain-proof agent is uniformly coated on the surface of the ceramic tile by a grinding disc at a speed of 40-70 revolutions per minute, the above steps are repeated 5-10 times, and then the penetrating stain-proof agent on the surface of the ceramic tile is dried by a grinding disc at a speed of ≥1000 revolutions per minute; In step S2, the curing and sealing agent is first added dropwise on the surface of the ceramic tile, and then the curing and sealing agent is uniformly coated on the surface of the ceramic tile by a grinding disc at a speed of 50-60 revolutions per minute, the above steps are repeated 5-10 times, and then the curing and sealing agent on the surface of the ceramic tile is dried by a grinding disc at a speed of ≥1000 revolutions per minute; In step S3, the cleaning softener is first dripped on the surface of the ceramic tile, and then the cleaning softener is coated on the surface of the ceramic tile by using a grinding disc at a rotating speed of 45-65 rpm, and the above steps are repeated for 6-20 times, and then the cleaning softener on the surface of the ceramic tile is dried by using a grinding disc at a rotating speed of ≥1000 rpm.

[0014] The conventional grinding disc uses a high-speed motor at 1000-3000 rpm to quickly spray the anti-fouling coating on the surface of the ceramic tile. The high-speed rotation causes most of the coating material to be thrown off the tile surface, resulting in low material utilization. Especially for matte tiles, the conventional process only adds one layer of coating, and the anti-fouling layer is even thinner. The present application first coats slowly to help the relevant agents to fully penetrate the surface of the ceramic tile, and then the surface residual liquid is dried by high speed.

[0015] Preferably, the tool for mechanically removing the glaze surface layer in step S3 is a nylon brush wheel, and the cross section of a single brush wire of the nylon brush wheel is a cross-shaped or star-shaped special-shaped structure, and the Shore hardness is D60-D75. Through the cooperation of the special-shaped structure and the hardness, more cutting edges than the conventional circular brush wire cross section can be provided, which significantly improves the scraping efficiency of the glaze surface layer and improves the scraping effect. The design target of the conventional nylon brush wheel is used for polishing and brightening, which is different from the use in the present application.

[0016] Further preferably, the nylon brush wheel is loaded on a rotating disc, and the nylon brush wheel is rotated by rotating the rotating disc to polish and grind the surface of the ceramic tile and mechanically remove the anti-fouling layer. The nylon brush wheel loaded on the rotating disc has multiple pieces, the brush wires on the nylon brush wheel are distributed in clusters, and a chip removal channel is provided between the brush wire clusters. The nylon brush wheel is divided into high-density brush wheels and low-density brush wheels according to the number of brush wire clusters thereon, and the arrangement mode of the high-density brush wheels and the low-density brush wheels on the rotating disc is that at most two adjacent brush wheels have the same density. By alternately arranging the high-density brush wheels and the low-density brush wheels, the high-density brush wire clusters provide the main mechanical scraping force to ensure the effective peeling of the residual film layer on the surface, and the low-density brush wheels help to smoothly remove the chips.

[0017] Further preferably, the width of the chip removal channel between the high-density brush wheel and the low-density brush wheel is 1 / 5 to 1 / 3 of the width of a single bristle cluster of the high-density brush wheel, the circumscribed circle diameter of the cross-section of a single bristle is 0.2 to 0.3 mm, and the bristle length is 25 to 35 mm. This optimized channel width provides ample overflow space and a path for the softened residue (slurry) to be removed, preventing secondary adhesion caused by repeated rolling between the brush wheel and the brick surface. A specific proportion of channel width between the bristle clusters ensures that the gap can effectively accommodate and remove the removed residue (waste chips) without being too wide and affecting the continuity of the brush wheel's cleaning effect. Combined with the circumscribed circle diameter and length of the bristle cross-section, it is more suitable for precise removal of residues on the glaze surface.

[0018] The nylon brush wheel's unique cross-section, specific hardness (D60~D75), and high and low density arrangement design ensure that it can effectively scrape away chemically softened surface residues without damaging the glaze.

[0019] This invention proposes a stain-resistant ceramic tile, which is obtained by the aforementioned stain-resistant treatment method.

[0020] This invention proposes an antifouling treatment system for use in conjunction with the aforementioned antifouling treatment method, comprising: A conveyor unit used to transport ceramic tiles; The coating application unit includes storage tanks for holding penetrating antifouling agent, curing and sealing agent, and cleaning and softening agent, a pumping system, and a dripping device; The grinding disc coating unit includes several sets of slow grinding discs and several sets of fast grinding discs. The rotation speed of the slow grinding discs and the fast grinding discs is controlled by several sets of variable frequency motors. The method achieves a minimum rotation speed of 40 rpm for the slow grinding discs and a rotation speed of at least 1000 rpm for the fast grinding discs.

[0021] Multiple slow coating stations and fast drying stations for the penetrating antifouling agent, multiple slow coating stations and fast drying stations for the curing and sealing agent, and multiple slow coating stations and fast drying stations for the cleaning and softening agent are sequentially arranged on the transmission unit. The coating application unit applies the penetrating antifouling agent, the curing and sealing agent, and the cleaning and softening agent respectively at the slow coating station corresponding to the penetrating antifouling agent, the curing and sealing agent, and the cleaning and softening agent, and then achieves uniform coating through the slow grinding disc; the fast grinding disc quickly dries the residual liquid on the glaze surface at the fast drying station corresponding to the penetrating antifouling agent, the curing and sealing agent, and the cleaning and softening agent. The last fast drying station of the cleaning softener is integrated with a mechanical cleaning device, the mechanical cleaning device uses a nylon brush wheel with a Shore hardness of D60-D75, and a single brush wire of the nylon brush wheel has a cross-shaped or star-shaped special-shaped structure. A control system is used to coordinate the operation sequence of the conveying unit, the coating application unit, and the grinding disc coating unit, and control the process parameters of the units.

[0022] Through the cooperation of the conveying unit, the coating application unit, the grinding disc coating unit, the stations, and the control system, the control system coordinates the operation sequence of the units and controls the process parameters, and effectively implements the aforementioned anti-fouling treatment method.

[0023] Preferably, a recycling filter device is integrated in the slow coating station of the selective cleaning unit to recycle and filter the used cleaning softener.

[0024] The application discloses an anti-fouling treatment method applied to a ceramic tile surface, a nylon brush wheel used in cooperation with the anti-fouling treatment method, a system, and an anti-fouling ceramic tile obtained by the method. The method overturningly adopts a "penetration anti-fouling-curing hole sealing-selective cleaning" step-by-step treatment process, constructs an anti-fouling sealing layer in the ceramic tile pores by penetrating an anti-fouling agent and a curing hole sealing agent, and accurately removes the residual glaze surface coating by the synergistic effect of a special nylon brush wheel and a cleaning softener, so that the original glaze surface of the ceramic tile is completely exposed after high-temperature firing. The obtained ceramic tile product perfectly retains the natural texture of the glaze layer and the properties of the glaze surface (high hardness, wear resistance, chemical inertness, and optical stability), and has a long-lasting anti-fouling property, thereby solving the technical problems that in the traditional waxing anti-fouling route, an organic anti-fouling film layer is added to the surface layer of the ceramic tile, the properties of the film layer are not as good as those of the protected glaze surface, the film layer is easily worn in use, the anti-fouling property is not long-lasting, and the appearance is not beautiful.

[0070] Comparative Example 1 The same sample as in Example 1 is used, and a commercially available water-based antifouling agent and a traditional water-based antifouling process (surface film forming type) are used for treatment.

[0071] After the above antifouling treatment, each sample is tested, and the experimental data are as follows: Table 1 As can be seen from the above table data, in Examples 1-3 of the present application, the "penetration antifouling-curing sealing-selective removal" step-by-step treatment process is used, the antifouling agent and the curing sealant are used to form an antifouling material in the pores of the ceramic tile, and the synergistic effect of the special nylon brush wheel and the cleaning softener is used to accurately remove the residual coating on the glaze surface, so that the original glaze of the ceramic tile after high-temperature firing is completely exposed. The obtained ceramic tile product not only perfectly retains the natural texture of the glaze layer and the performance of the glaze itself (high hardness, wear resistance, chemical inertness and optical stability), but also has long-lasting antifouling performance.

[0072] Comparative Example 1 has better antifouling performance in the initial state, but after QUV aging for 1500 hours, it appears obvious yellowing, after 1000 times of steel wool rubbing, obvious scratches appear, and the organic film layer is worn out, the gloss retention rate and the antifouling performance decrease significantly. It can be seen that the examples of the present application not only have a large advantage in antifouling, wear resistance and other quantitative indicators compared with the prior art, but more importantly, the aesthetic texture and long-term durability of the ceramic tile are fundamentally improved, and the main technical problem of the present application is solved. On the other hand, Comparative Example 1 also proves the defects of the prior art in the glaze surface film forming. Although the commercially available antifouling agent can achieve a certain antifouling property (5 levels), the coating film (organic film layer) on the glaze surface becomes the bearing surface of all external forces, resulting in poor wear resistance of the coating (almost complete failure of antifouling property after rubbing), and easy aging and yellowing. This fundamentally contrasts with the durable design of the present application, which uses the original fired glaze to bear external forces, and the antifouling function is hidden in the pores of the glaze layer, highlighting the innovative value of the present application.

[0073] Comparative Example 2 The same sample as in Example 1, the agents used and the tools are used, the difference is that the grinding plate speed in steps S1-S3 is different, no slow grinding plate is used, and the corresponding number of fast grinding plates (2000 rpm) is used for corresponding times.

[0074] Comparative Example 3 The same sample, the same agent and the specific grinding disc speed (slow first and fast later) as in Example 1 were used, with the difference that a conventional nylon brush wheel with a conventional Shore hardness D90 was used, with a single brush wire diameter of 1 mm and a conventional circular cross-section, with a brush wire length of 60 mm and a vertical array arrangement.

[0075] Comparative Example 4 The difference from Example 1 is that the penetration antifouling agent is mixed directly with the solidification pore sealing agent and applied once.

[0076] Table 2 From the data in the above table, it can be seen that, in Comparative Example 1, after replacing the conventional high-speed grinding disc speed, the antifouling effect of Comparative Example 2 significantly decreased at the beginning, most of the glaze pores were not effectively sealed, among which the hydrophobic performance decreased significantly, the gloss retention rate decreased, and the wear resistance slightly decreased, but the effect was better than that in Comparative Example 1. This shows the key role of the "slow first and fast later" speed process. The full-speed causes the coating to be thrown off in large quantities before penetration, which cannot effectively enter and fill the pores, resulting in poor initial antifouling performance (level 2), which cannot meet the national standard for antifouling. Although the glaze is exposed, which makes the wear resistance and aging resistance data have certain improvement compared with the traditional commercially available antifouling agent, but the core antifouling function cannot be realized.

[0077] In Comparative Example 1, after replacing the conventional nylon brush wheel, the initial antifouling effect of Comparative Example 3 significantly decreased, and there were obvious scratches after the steel wool friction, which shows the necessity of "special cleaning tools". The conventional brush wheel with high hardness (D90), thick diameter and no chip design can remove part of the surface coating, but it will scratch the glaze, damage the aesthetic effect and create new hiding points. At the same time, its cleaning efficiency is low, which causes the pore mouth sealing material to be partially damaged, and the initial and wear-resistant antifouling properties (level 3, level 2) are significantly decreased.

[0078] Comparative Example 1, the distribution of the penetration antifouling agent and the curing pore sealing agent is replaced by mixed one-time distribution. In Comparative Example 4, the uniformity is poor and the texture is poor in macroscopic observation, and the microscopic observation shows that there is a discontinuous hardened coating film residue on the glaze surface, the film thickness is uneven, the initial antifouling and hydrophobic performance are significantly reduced, and after the coating film is rubbed by steel wool, scratches appear at the rubbed place, the hydrophobic performance is significantly reduced, and the gloss retention rate is significantly reduced. It can be seen that the specific sequence of the distribution process is irreplaceable. After the penetration antifouling agent and the curing pore sealing agent are mixed and applied once, the components of different polarities interfere with each other and are rapidly cross-linked into a film on the surface, which seriously hinders the penetration into the deep pores (forming a structure of “surface blocking and internal emptiness”). This leads to poor initial antifouling (level 3), and the hardened coating film formed on the surface is uneven and easy to powder, and the wear resistance and aging resistance are comprehensively deteriorated. This also proves that the step-by-step sequence of first penetrating and filling and then curing and sealing plays a key role in the results of forming an antifouling material in the deep pores in the present application.

[0079] Comparative Example 5 (D5) The difference from Example 1 is that an equal amount of conventional nano-silica dispersion liquid is used to replace the nano-silica dispersion liquid pretreated with silane coupling agent KH-560 in the penetration antifouling agent.

[0080] Comparative Example 6 (D6) The difference from Example 1 is that an equal amount of conventional acrylic emulsion is used to replace the fluorosilicon-modified acrylic ester copolymer emulsion in the penetration antifouling agent.

[0081] Comparative Example 7 (D7) The difference from Example 1 is that an equal amount of conventional mica powder is used to replace the silane-modified flaky mica powder in the curing pore sealing agent.

[0082] Comparative Example 8 (D8) The difference from Example 1 is that an equal amount of epoxy resin is used to replace the epoxy-acrylic hybrid emulsion in the curing pore sealing agent.

[0083] Comparative Example 9 (D9) The difference from Example 1 is that an equal amount of acrylic resin is used to replace the epoxy-acrylic hybrid emulsion in the curing pore sealing agent.

[0084] Table 3 From the above table data, in Comparative Example 1, the conventional nano-silica dispersion liquid is used in the penetration antifouling agent. Since it is not pre-treated with silane, the conventional nano-SiO2 has poor compatibility with the resin, leading to uneven dispersion (agglomeration is observed under microscope), which affects the compactness of the pore filling. This directly causes the initial antifouling property to decrease (4 levels), and after wear resistance, the structure is more easily damaged, and the antifouling property drops to 3 levels, and the aging resistance also becomes poor. This shows that the untreated nanoparticles cannot achieve effective organic-inorganic hybrid enhancement.

[0085] In Comparative Example 1, the conventional acrylic emulsion is used in the penetration antifouling agent. Since it is not modified with silane, the surface energy of the conventional acrylic emulsion is high, and the antifouling property is poor (only 3 levels initially), and it cannot achieve "selective cleaning", leading to continuous coating film remaining on the surface. After rubbing, it is quickly worn (the antifouling property decreases to 2 levels), and it is easily yellowed and aged. This highlights the importance of fluorosilicon segments for providing low surface energy antifouling property and achieving subsequent cleaning steps.

[0086] From the above comparison, it can be seen that the silane modification treatment of the nano-silica dispersion liquid and the fluorosilicon modification of the acrylic emulsion play an important role in the formulation of the penetration antifouling agent.

[0087] In Comparative Example 1, the conventional unmodified sheet mica powder is used in the solidification pore sealing agent in Comparative Example 1. The conventional mica powder has weak adhesion to the resin, and is arranged disorderly at the pore opening, which is easy to protrude and seal the pores. This leads to acceptable initial antifouling property (4 levels), but after wear resistance, the structure is easily damaged, the antifouling property decreases (3 levels), and the aging resistance decreases. This shows that the filler that is not modified with silane cannot form a dense and stable physical barrier.

[0088] In Comparative Example 1, equal amounts of epoxy resin are used in the solidification pore sealing agent in Comparative Example 8, and equal amounts of acrylic resin are used in the solidification pore sealing agent in Comparative Example 9, which respectively replace the epoxy-acrylic hybrid emulsion. In Comparative Example 8, the pure epoxy resin has too much rigidity and insufficient flexibility, leading to brittle and easily cracked coating film (visible under microscope), and large difference in thermal expansion coefficient with the glaze, which is easy to peel off after aging. Although the initial performance is acceptable, the durability is poor. The hybrid structure balances the adhesion, rigidity and flexibility. In Comparative Example 9, the pure acrylic resin has much poorer adhesion and chemical resistance than the epoxy, leading to poor initial antifouling property (2 levels), soft coating film, and poor wear resistance (antifouling completely fails after rubbing), and extremely poor aging resistance. This proves that a single acrylic system cannot meet the requirements of high-performance pore sealing.

[0089] It can be seen that in the solidification pore sealing agent, the silane modification of the sheet mica powder and the epoxy-acrylic hybrid emulsion in the formulation are indispensable, and the solidification pore sealing agent of the formulation cooperates with the penetration antifouling agent to produce a synergistic effect, achieving effective penetration antifouling and solidification pore sealing of the glaze pores, and realizing long-term antifouling performance.

Any equivalent structure variations or direct / indirect applications in other related technical fields, which are made based on the contents of the present application, shall fall within the patent protection scope of the present application.
