Abstract
Description
Technical Field
[0001] The present invention relates to the field of ink, and in particular to a performance-stable ink, a preparation method thereof, and application thereof in ceramic products. Background Art
[0002] Ceramic ink is a type of ink specifically formulated for ceramic materials, typically used for printing patterns and decorating ceramics. Its composition differs from that of regular ink. Ceramic ink primarily consists of a pigment, a binder, and a solvent. The pigment undergoes special processing to adapt to the characteristics of the ceramic surface, ensuring vibrant, long-lasting color.
[0003] Some kitchen ceramic products such as casseroles that use ceramic ink may develop cracks or scratches around the ink patterns on the casseroles during daily use. When cooking at high temperatures on a gas stove, the incompletely burned gas will contain some carbon monoxide (the main components of incompletely burned gas include CO, CO2, nitrogen oxides, hydrocarbons and H2O, etc.), and the iron oxide used as a pigment will undergo an oxidation-reduction reaction with carbon monoxide, which will cause fading and poor stability.
[0004] Therefore, a performance-stable ink, a preparation method thereof and application in ceramic products are proposed. Summary of the Invention
[0005] The purpose of the embodiments of the present invention is to provide an ink with stable performance, a preparation method thereof, and its application in ceramic products, aiming to solve the problem of cracks or scratches around the ink pattern of the casserole during daily use. The iron oxide used as a pigment will undergo an oxidation-reduction reaction with carbon monoxide, which will cause fading and poor stability.
[0006] Specific technical solution: A stable performance ink comprising the following components: enhanced color, solvent, dispersant, surfactant, preservative and modified binder; The enhanced color includes Fe2O3 and Ag2O added in a weight ratio of 7-10:1-3; the modified adhesive includes bauxite powder and resin added in a weight ratio of 1-3:2-4.
[0007] Therefore, adding a modified binder composed of bauxite powder and resin to the ink can ensure the performance stability of iron oxide in applications such as ceramic inks, colors and coatings, especially in the defixation or stabilization treatment during ceramic firing to enhance the durability and adhesion of iron oxide; Silver oxide, a bait-like protective component, is added to the color iron oxide in the ink. When encountering redox reactions that may occur in some application scenarios, the divalent silver ions in the silver oxide are more active in redox reactivity than the trivalent iron ions, and can preferentially replace the color iron oxide for redox reactions, protecting the trivalent iron ions, locking the iron oxide as the color, and improving the stability of the ink. In addition, the proportion of iron oxide as a red pigment is much greater than that of black silver oxide, so the overall color is still dark red. After losing some silver oxide, the overall color is still red.
[0008] In one embodiment, the performance-stable ink includes the following raw materials in parts by weight: 32 parts of enhanced color, 68 parts of solvent, 12 parts of dispersant, 15 parts of surfactant, 7 parts of preservative and 35 parts of modified binder.
[0009] In one embodiment, the modified adhesive comprises bauxite powder and resin added in a weight ratio of 2:3.
[0010] Furthermore, the resin includes acrylic resin, polyurethane and silicate resin.
[0011] In one embodiment, the enhanced color comprises Fe2O3 and Ag2O added in a weight ratio of 9:2; wherein the method for preparing the enhanced color comprises the following steps: Step 1: Grind Fe2O3 and Ag2O into powder respectively; Step 2: Use circulating air mixing equipment for comprehensive and systematic mixing.
[0012] Furthermore, the circulating air blowing and mixing equipment includes an air blowing collision mixing tank, a first main air supply pipe and a second main air supply pipe; The first main air supply pipe and the second main air supply pipe are symmetrically distributed on both sides of the blowing collision mixing tank and are connected to the blowing collision mixing tank; an exhaust mechanism is installed between the first main air supply pipe and the second main air supply pipe, and the exhaust mechanism is connected to the first main air supply pipe and the second main air supply pipe respectively, and the exhaust mechanism is connected to the blowing collision mixing tank through the main exhaust pipe; a plurality of feeding hoppers are installed on the blowing collision mixing tank; It should be noted that the multiple feeding hoppers can be two, three, four, five, etc., and there is no limit on the specific number, as long as it can be used to add a variety of materials. Here, the specific number of the multiple feeding hoppers is preferably two; Multiple materials are added into the blowing collision mixing tank through multiple feeding hoppers, and the multiple blowers installed inside the blowing collision mixing tank drive the collision to form airflow; The exhaust mechanism is started to form an exhaust airflow of the main exhaust pipe inside the blowing collision mixing tank by using the main exhaust pipe. The exhaust mechanism then separates the exhaust airflow of the main exhaust pipe carrying multiple materials and introduces them into the first main supply air pipe and the second main supply air pipe respectively, forming the supply air flow of the first main supply air pipe and the second main supply air pipe; The airflows carrying various materials collide and mix.
[0013] Therefore, the iron oxide and silver oxide crushed into powder enter the blowing collision mixing tank through the feeding hopper, and the blowing collision mixing tank uses multiple blowers to blow the iron oxide and silver oxide powders to form an airflow for collision mixing. Thereafter, the exhaust mechanism is started to use the main exhaust pipe to form a main exhaust pipe exhaust airflow inside the blowing collision mixing tank. The exhaust mechanism then separates the main exhaust pipe exhaust airflow introduced and carrying a variety of materials into the first main supply air pipe and the second main supply air pipe, forming the first main supply air pipe supply airflow and the second main supply air pipe supply airflow; multiple air flows carrying a variety of materials are achieved without collision mixing, thereby improving the mixing uniformity of the iron oxide and silver oxide powder, and is conducive to strengthening the preferential replacement of silver oxide for color iron oxide for redox reaction, protecting trivalent iron ions, ensuring efficient locking of iron oxide as color, and improving the stability of the ink.
[0014] It should be noted that the exhaust mechanism is composed of a motor and multiple blades.
[0015] Furthermore, the air-blast collision mixing tank is internally installed with a No. 1 feed pipe and a No. 2 feed pipe distributed in parallel, a No. 1 side feed pipe is installed on the side wall of the No. 1 feed pipe and is connected to the No. 1 side feed pipe; a plurality of No. 1 interspersed feed pipes are arranged at equal intervals on the No. 1 side feed pipe, and the plurality of No. 1 interspersed feed pipes are all connected to the No. 1 side feed pipe; A No. 2 side feed pipe is installed on the side wall of the No. 2 feed pipe and is connected to the No. 2 side feed pipe; a plurality of No. 2 interpenetrating feed pipes are arranged at equal intervals on the No. 2 side feed pipe, and the plurality of No. 2 interpenetrating feed pipes are all connected to the No. 2 side feed pipe; Multiple No. 1 interpenetrating feed pipes are sequentially interpenetrated in the gaps of multiple No. 2 interpenetrating feed pipes to form multiple hedging units; multiple feeding holes are opened on the No. 1 side feed pipe, the No. 2 side feed pipe, the No. 1 interpenetrating feed pipe and the No. 2 interpenetrating feed pipe; Multiple hedging units blow the blower to form an airflow carrying materials, which is discharged through multiple feeding holes and then subjected to unit modular systematic collision and mixing.
[0016] Therefore, the iron oxide and silver oxide crushed into powder are added to the inside of the blowing collision mixing tank through multiple feeding hoppers, and then blown by multiple blowers installed correspondingly inside the blowing collision mixing tank to form an air flow carrying the material, which is discharged through multiple feeding holes; multiple No. 1 interlaced feeding pipes are sequentially interlaced in the gaps of multiple No. 2 interlaced feeding pipes to form multiple hedging units; thus, modular unit systematic collision mixing is achieved, and the subsequent mixing cycle is shortened on the basis of improving the mixing efficiency; thus, the mixing uniformity of the iron oxide and silver oxide powders is promoted; It should also be noted that after the multiple hedging units have completed the collision and mixing of the airflow carrying the materials, the exhaust mechanism uses the main exhaust pipe to form the main exhaust pipe exhaust airflow inside the blowing collision mixing tank.
[0017] Furthermore, the first main air supply pipe and the second main air supply pipe adopt the same structure, and a plurality of secondary collision pipe groups are installed on the first main air supply pipe, and the secondary collision pipe groups include secondary exhaust pipes, which are located on both sides of the secondary exhaust pipe and are connected to a secondary air supply pipe, and the secondary air supply pipes are connected to the first main air supply pipe; In the process of the first main air supply duct and the second main air supply duct separately guiding the air flow carrying the material, the secondary exhaust duct is used to mobilize the air flow carrying the material in the vertical direction along the flow of the air flow to perform collision mixing.
[0018] Therefore, during the flow of the air flow in the first main air supply duct and the second main air supply duct, a secondary exhaust duct is used to mobilize the air flow carrying materials in the vertical direction of the air flow locally for collision mixing, so as to further improve the collision mixing of different materials, which is conducive to the comprehensive and uniform mixing of different materials.
[0019] Another object of the present invention is to provide a method for preparing a performance-stable ink, the method comprising the following steps: Step 1: Add the enhanced color, surfactant and preservative to the solvent, stir and mix at a stirring speed of 60-160 r / min; then filter and grind; Step 2: Add dispersant and modified binder, stir and mix at a stirring speed of 200-300 r / min; reduce the stirring speed to 120-180 r / min, and then provide ultrasonic environment for treatment; Step 3: Add defoaming agent and stir at a speed of 20-30 r / min. After it stops, filter and take the filtrate to prepare ink with stable performance.
[0020] Another object of the present invention is to provide an ink with stable performance for use in ceramic products.
[0021] It should be noted that although silver oxide decomposes into silver and oxygen at 200-300°C, silver will react with oxygen to form silver oxide again when fired at 1000-1400°C.
[0022] Compared with the prior art, the present invention can achieve: 1. Adding a modified binder composed of bauxite powder and resin to the ink can ensure the performance stability of iron oxide in applications such as ceramic inks, colors and coatings, especially during ceramic firing to enhance the durability and adhesion of iron oxide by defixing or stabilizing it; Silver oxide, a bait-like protective component, is added to the color iron oxide in the ink. When encountering redox reactions that may occur in some application scenarios, the divalent silver ions in the silver oxide are more active than the trivalent iron ions in the redox reaction, and can preferentially replace the color iron oxide to undergo redox reactions, protecting the trivalent iron ions, thereby locking the iron oxide as the color and improving the stability of the ink. In addition, the proportion of iron oxide as a red pigment is much greater than that of silver oxide as a black pigment, so the overall color is still dark red. Even after losing some silver oxide, the overall color is still red. Second, the iron oxide and silver oxide crushed into powder enter the blowing collision mixing tank through the feeding hopper, and the blowing collision mixing tank uses multiple blowers to blow the iron oxide and silver oxide powders to form an airflow for collision mixing. Thereafter, the exhaust mechanism is started to use the main exhaust pipe to form a main exhaust pipe exhaust airflow inside the blowing collision mixing tank. The exhaust mechanism then separates the main exhaust pipe exhaust airflow introduced and carrying a variety of materials into the first main air supply pipe and the second main air supply pipe, forming the first main air supply pipe air supply airflow and the second main air supply pipe air supply airflow; multiple air flows carrying a variety of materials are achieved without collision mixing, thereby improving the mixing uniformity of the iron oxide and silver oxide powder, and is conducive to strengthening the silver oxide to preferentially replace the color iron oxide for redox reaction, protecting the trivalent iron ions, ensuring efficient locking of the iron oxide as the color, and improving the stability of the ink; 3. The iron oxide and silver oxide crushed into powder are added to the inside of the blowing collision mixing tank through multiple feeding hoppers, and then blown by multiple blowers installed correspondingly inside the blowing collision mixing tank to form an air flow carrying the material, which is discharged through multiple feeding holes; multiple No. 1 interlaced feeding pipes are sequentially interlaced in the gaps of multiple No. 2 interlaced feeding pipes to form multiple hedging units; to achieve unit modular systematic collision mixing, shorten the subsequent mixing cycle on the basis of improving mixing efficiency; and promote the mixing uniformity of iron oxide and silver oxide powders; 4. During the flow of the air flow in the first main air supply duct and the second main air supply duct, a secondary exhaust duct is used to mobilize the air flow carrying materials in the vertical direction along the flow of the air flow to perform collision mixing, so as to further improve the collision mixing of different materials, which is conducive to the comprehensive and uniform mixing of different materials.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. The specific implementation of the present invention is described in detail below with reference to the specific embodiments.
[0026] Example 1, a stable performance ink, comprising the following components: an enhanced color, a solvent, a dispersant, a surfactant, a preservative, and a modified binder; Among them, the enhanced color includes Fe2O3 and Ag2O added in a weight ratio of 7:1; the modified adhesive includes bauxite powder and resin added in a weight ratio of 1:2.
[0027] Therefore, adding a modified binder composed of bauxite powder and resin to the ink can ensure the performance stability of iron oxide in applications such as ceramic inks, colors and coatings, especially in the defixation or stabilization treatment during ceramic firing to enhance the durability and adhesion of iron oxide; Silver oxide, a bait-like protective component, is added to the color iron oxide in the ink. When encountering redox reactions that may occur in some application scenarios, the divalent silver ions in the silver oxide are more active in redox reactivity than the trivalent iron ions, and can preferentially replace the color iron oxide for redox reactions, protecting the trivalent iron ions, locking the iron oxide as the color, and improving the stability of the ink. In addition, the proportion of iron oxide as a red pigment is much greater than that of black silver oxide, so the overall color is still dark red. After losing some silver oxide, the overall color is still red.
[0028] Example 2, a stable performance ink, comprising the following components: an enhanced color, a solvent, a dispersant, a surfactant, a preservative, and a modified binder; Among them, the enhanced color includes Fe2O3 and Ag2O added in a weight ratio of 10:3; the modified adhesive includes bauxite powder and resin added in a weight ratio of 3:4.
[0029] Example 3, a stable performance ink, comprising the following components: an enhanced color, a solvent, a dispersant, a surfactant, a preservative, and a modified binder; The enhanced color comprises Fe2O3 and Ag2O added in a weight ratio of 9:2; and the preparation method of the enhanced color comprises the following steps: Step 1: Grind Fe2O3 and Ag2O into powder respectively; Step 2: Use circulating air mixing equipment for comprehensive and systematic mixing.
[0030] Example 4: This example is described in detail based on Example 3. A stable performance ink comprises the following raw materials in parts by weight: 32 parts of enhanced color, 68 parts of solvent, 12 parts of dispersant, 15 parts of surfactant, 7 parts of preservative and 35 parts of modified binder.
[0031] Example 5: This example is described in detail based on Example 3. The modified adhesive comprises bauxite powder and resin added in a weight ratio of 2:3; the resin comprises acrylic resin, polyurethane and silicate resin.
[0032] Example 6, as Figure 2-4 : The circulating air blowing and mixing equipment includes an air blowing collision mixing tank 200, a first main air supply pipe 300 and a second main air supply pipe 600; The first main air supply pipe 300 and the second main air supply pipe 600 are symmetrically distributed on both sides of the blowing collision mixing tank 200 and are connected to the blowing collision mixing tank 200; an exhaust mechanism 500 is installed between the first main air supply pipe 300 and the second main air supply pipe 600, and the exhaust mechanism 500 is connected to the first main air supply pipe 300 and the second main air supply pipe 600 respectively, and the exhaust mechanism 500 is connected to the blowing collision mixing tank 200 through the main exhaust pipe 400; a plurality of feeding hoppers 100 are installed on the blowing collision mixing tank 200; It should be noted that the multiple feeding hoppers 100 can be two, three, four, five, etc., and there is no specific limit on the number as long as it can be used to load a variety of materials. Here, it is preferred that the specific number of the multiple feeding hoppers 100 is two; Multiple materials are added into the blowing collision mixing tank 200 through multiple feeding hoppers 100, and are driven to collide with each other by multiple blowers installed correspondingly inside the blowing collision mixing tank 200, forming an airflow; The exhaust mechanism 500 is started to form the main exhaust pipe exhaust airflow inside the mixing tank 200 by using the main exhaust pipe 400 (for details, please refer to Figure 4 The exhaust mechanism 500 then separates the main exhaust pipe exhaust airflow carrying multiple materials and introduces them into the first main air supply pipe 300 and the second main air supply pipe 600, forming the first main air supply pipe air flow (for details, please refer to Figure 4 The air supply direction of the first main air supply pipe is shown as A) and the air supply flow of the second main air supply pipe is shown as A). Figure 4 Air supply direction C of the second main air supply duct shown); The airflows carrying various materials collide and mix.
[0033] Therefore, the iron oxide and silver oxide crushed into powder enter the blowing collision mixing tank 200 through the feeding hopper 100, and the blowing collision mixing tank 200 uses multiple blowers to blow the iron oxide and silver oxide powders to form an airflow for collision mixing. Thereafter, the exhaust mechanism 500 is started to use the main exhaust pipe 400 to form a main exhaust pipe exhaust airflow inside the blowing collision mixing tank 200. The exhaust mechanism 500 then separates the main exhaust pipe exhaust airflow introduced and carrying a variety of materials and introduces them into the first main air supply pipe 300 and the second main air supply pipe 600 respectively, forming the first main air supply pipe air supply airflow and the second main air supply pipe air supply airflow; multiple air flows carrying a variety of materials are achieved without collision mixing, thereby improving the mixing uniformity of the iron oxide and silver oxide powders, and is beneficial to strengthening the preferential replacement of silver oxide for color iron oxide for redox reaction, protecting trivalent iron ions, ensuring efficient locking of iron oxide as color, and improving the stability of the ink.
[0034] It should be additionally explained that the exhaust mechanism 500 is composed of a motor and a plurality of blades.
[0035] Further, such as Figure 3 : The air-blast collision mixing tank 200 is internally installed with a No. 1 feed pipe 210 and a No. 2 feed pipe 220 that are distributed in parallel. A No. 1 side feed pipe 2101 is installed on the side wall of the No. 1 feed pipe 210 and is connected to the No. 1 side feed pipe 2101; a plurality of No. 1 interspersed feed pipes 2102 are evenly spaced on the No. 1 side feed pipe 2101, and the plurality of No. 1 interspersed feed pipes 2102 are all connected to the No. 1 side feed pipe 2101; A No. 2 side feed pipe 2201 is installed on the side wall of the No. 2 feed pipe 220 and is connected to the No. 2 side feed pipe 2201; a plurality of No. 2 interpenetrating feed pipes 2202 are evenly spaced on the No. 2 side feed pipe 2201, and the plurality of No. 2 interpenetrating feed pipes 2202 are all connected to the No. 2 side feed pipe 2201; Multiple No. 1 interpenetrating feed pipes 2102 are sequentially interpenetrated in the gaps between multiple No. 2 interpenetrating feed pipes 2202 to form multiple counterbalancing units; multiple feeding holes are provided on the No. 1 side feed pipe 2101, the No. 2 side feed pipe 2201, the No. 1 interpenetrating feed pipe 2102, and the No. 2 interpenetrating feed pipe 2202; Multiple hedging units blow the blower to form an airflow carrying materials, which is discharged through multiple feeding holes and then subjected to unit modular systematic collision and mixing.
[0036] Therefore, the iron oxide and silver oxide crushed into powder are added to the interior of the blowing collision mixing tank 200 through multiple feeding hoppers 100, and then blown by multiple blowers correspondingly installed inside the blowing collision mixing tank 200 to form an air flow carrying the material, which is discharged through multiple feeding holes; multiple No. 1 interlaced feeding pipes 2102 are sequentially interlaced in the gaps of multiple No. 2 interlaced feeding pipes 2202 to form multiple hedging units; thus, modular unit systematic collision mixing is achieved, and subsequent mixing cycles are shortened on the basis of improving mixing efficiency; thus, the mixing uniformity of the iron oxide and silver oxide powders is promoted; It should also be noted that after the multiple hedging units have completed the collision and mixing of the airflow carrying the materials, the exhaust mechanism 500 uses the main exhaust pipe 400 to form the main exhaust pipe exhaust airflow inside the blowing collision mixing tank 200.
[0037] Further, such as Figure 2 The first main air supply duct 300 and the second main air supply duct 600 have the same structure. A plurality of secondary collision tube groups 310 are installed on the first main air supply duct 300. The secondary collision tube groups 310 include secondary exhaust ducts 330. Two sides of the secondary exhaust ducts 330 are connected to a secondary air supply duct 320, and the secondary air supply ducts 320 are connected to the first main air supply duct 300. During the process of the first main air supply duct 300 and the second main air supply duct 600 separately guiding the airflow carrying materials, the secondary exhaust duct 330 is used to mobilize the airflow carrying materials in the vertical direction along the flow of the airflow for collision and mixing.
[0038] Therefore, during the flow of the air flow in the first main air supply duct and the second main air supply duct, the secondary exhaust duct 330 is used to mobilize the air flow carrying materials in the vertical direction along the flow of the air flow to perform collision mixing, thereby further improving the collision mixing of different materials, which is conducive to the comprehensive and uniform mixing of different materials.
[0039] Example 7: This example provides a method for preparing a performance-stable ink. The method for preparing the performance-stable ink comprises the following steps: Step 1: Add the enhanced color, surfactant and preservative to the solvent, stir and mix at a stirring speed of 60-160 r / min; then filter and grind; Step 2: Add dispersant and modified binder, stir and mix at a stirring speed of 200-300 r / min; reduce the stirring speed to 120-180 r / min, and then provide ultrasonic environment for treatment; Step 3: Add defoaming agent and stir at a speed of 20-30 r / min. After it stops, filter and take the filtrate to prepare ink with stable performance.
[0040] Example 8: This example provides a performance-stable ink for use in ceramic products.
[0041] It should be noted that although silver oxide decomposes into silver and oxygen at 200-300°C, silver will react with oxygen to form silver oxide again when fired at 1000-1400°C.

[0044]
[0045] The above sample AO was tested using a colorimeter, and the test results are shown in Table 2; Table 2 shows the three parameters L, a, and b of the sample AO test (L, a, and b represent brightness, red-green value, and yellow-blue value respectively)
[0046]
[0047]
[0048]
[0049]
[0050]
[0051] Through Table 1 and Figure 1 The three parameters L, a, and b represent brightness, red-green value, and yellow-blue value, respectively. It can be seen that when inks 1 to 108 with added Ag2O were placed in a high-temperature environment that was not fully burned, the three parameters L, a, and b remained basically unchanged. When inks 109 to 126 without added Ag2O were placed in a high-temperature environment that was not fully burned, the L parameter increased significantly, the a parameter decreased significantly, and the b parameter increased, with basically no change. From the rule that "the larger the L value, the brighter the color; the smaller the L value, the darker the color; the larger the absolute value of the a value, the higher the color saturation", we can know that: adding a modified binder composed of bauxite powder and resin to the ink can ensure the performance stability of iron oxide in applications such as ceramic inks, colors and coatings, especially during ceramic firing, the defixation or stabilization treatment can enhance the durability and adhesion of iron oxide; adding a bait-type protective component silver oxide to the color iron oxide in the ink, when encountering redox reactions that may occur in some application scenarios, the redox reactivity of the divalent silver ions in the silver oxide is higher than that of the trivalent iron ions, and can preferentially replace the color iron oxide for redox reactions, thereby protecting the trivalent iron ions, locking the iron oxide as the color, and improving the stability of the ink.
