Description

Technical Field

[0001] The invention relates to the field of glazes, and in particular to a negative oxygen ion ceramic surface glaze and a manufacturing method thereof. Background Art

[0002] Ceramic products, with their high density, excellent thermal stability, minimal shrinkage and deformation, easy washing and cleanliness, chemical stability, and durability, are a popular choice and have a broad market. Negative oxygen ion ceramics release negative ions by releasing electrons. These electrons are captured by molecules such as oxygen, forming "negative oxygen ions." These negatively charged oxygen molecules can then combine with one or more water molecules to form "air negative oxygen ions." When the concentration of negative oxygen ions in the air increases significantly, they neutralize the positively charged groups produced by human metabolism. Therefore, exposure to air can create a sense of well-being, like stepping into a forest. This sensation is particularly pronounced when humidity increases. Natural, odorless, non-toxic, and safe, ceramics purify the air, relieve fatigue, and promote health, while also possessing antibacterial, antimicrobial, and deodorizing properties. The amount of negative oxygen ions released by ceramic surface glazes has become a key indicator of their performance. While maintaining the various advantages of existing ceramic glazes, increasing their negative oxygen ion release is crucial. To this end, the present invention proposes a negative oxygen ion ceramic surface glaze and a manufacturing method thereof to solve the defects and shortcomings of the prior art.

[0144] The preparation steps of the negative oxygen ion ceramic surface glaze in this comparative example are the same as those in Example 1, except that there is no negative oxygen ion powder.

[0145] Performance testing:

[0146] 1. Detection of negative oxygen ion release of ceramic glaze:

[0147] The prepared glaze was evenly coated on a 3cm×3cm square ceramic sheet and hardened into shape by ultraviolet light. The ceramic sheet was then placed in a sealed chamber filled with a mixture of heated saturated air and water vapor. The temperature in the sealed chamber was controlled at 30°C and the relative humidity was 95%. The glaze on the upper layer of the ceramic sheet released negative oxygen ions in the sealed chamber. Finally, the amount of negative oxygen ions in the sealed chamber was measured.

[0148] 2. Hardness test of ceramic glaze surface:

[0149] The hardness of the prepared glaze was tested according to the standard GB / T6739-1996, using the A method testing machine method. The larger the H value, the greater the hardness of the glaze layer.

[0150] 3. Test of wear resistance of ceramic glaze surface

[0151] The ceramic glazes prepared in the above examples and comparative examples were tested for wear resistance according to the existing surface abrasion resistance method for glazed tiles (ISO 10545-7:1996 Determination of resistance to surface abrasion for glazed tiles).

[0152] The existing test steps are as follows: the abrasive is steel balls with the grade specified in ISO10545-7, 20 ml of deionized water, and 3.0 g of 80 mesh corundum sand or 3.0 g of 80 mesh quartz sand.

[0153] Test samples for Examples 1-5 and Comparative Examples 1-13 were prepared by applying equal masses of glaze to ceramic sheets of equal size and curing them for the same time. The glaze surfaces were tested using the aforementioned tools. The samples prepared in each embodiment were cleaned and dried to a constant weight before and after the wear test, and their weights were recorded. The wear results for each embodiment were determined based on the pre- and post-test weighing results.

[0154] Table 1:

[0155]

[0156]

[0157] Table 2:

[0158]

[0159] From the above, we can conclude that:

[0160] (1) The final hardness of the ceramic surface glaze varies depending on the mass ratio of the modified resin prepared by bisphenol A epoxy resin and polyether polyurethane oligomer with isocyanate terminal. Specifically, the higher the epoxy resin content, the greater the hardness of the ceramic surface glaze, but the release of negative oxygen ions will decrease.

[0161] (2) When the proportion of the polyether polyurethane oligomer with an isocyanate terminal in the step of preparing the modified resin is increased, the release amount of negative oxygen ions of the final ceramic surface glaze can be effectively increased, but the hardness of the ceramic surface glaze will also decrease.

[0162] (3) When the specific gravity of epoxy resin in the step of preparing modified resin is increased, the wear resistance of ceramic surface glaze can be effectively improved.

[0163] 4. The adhesion test of glaze shall be carried out in accordance with GB / T9286-1998 "Scratch test for paint and varnish films":

[0164] The test results are graded as follows:

[0165] Level 0: The cutting edge is completely smooth, without any falling off;

[0166] Level 1: There is a slight coating peeling off at the intersection of the cuts, but the cross-cut area affected cannot be significantly greater than 5%;

[0167] Level 2: Coating peels off at the intersection of the cuts and / or along the edges of the cuts, and the affected cross-cut area is significantly greater than 5%, but not significantly greater than 15%;

[0168] Level 3: The coating has partially or completely fallen off in large fragments along the cut edge and / or partially or completely peeled off at different locations on the grid. The affected cross-cut area is significantly greater than 15%, but not significantly greater than 35%.

[0169] Level 4: The coating is peeling off in large pieces along the cut edges, and / or some squares are partially or completely peeling off. The affected cross-cut area is significantly greater than 35%, but not significantly greater than 65%;

[0170] Level 5: The degree of thorn drop exceeds that of level 4.

[0171] Table 3:

[0172]

[0173] Table 4:

[0174]

[0175] From the above, we can conclude that:

[0176] (1) When silicon dioxide, titanium dioxide, zirconium dioxide, and zinc oxide in nano-oxide powders are reduced or removed, the adhesion and wear resistance of the final ceramic surface glaze are affected;

[0177] (2) When the raw materials of negative oxygen ion powder are changed, such as increasing the content of tourmaline powder, the release of negative oxygen ions can be increased, but the overall adhesion of the glaze on the ceramic surface will be reduced; reducing the content of tourmaline powder can increase the overall adhesion of the glaze on the ceramic surface but will reduce the release of negative oxygen ions on the ceramic surface.

[0178] 4. The ceramic glaze prepared in this embodiment was tested according to the standards of GB18582-2008 "Limits of Hazardous Substances in Interior Wall Paints for Interior Decoration and Decorative Materials" and JG / T24-2000 "Synthetic Resin Emulsion Sand Wall Architectural Paints":

The method for manufacturing the negative oxygen ion ceramic surface glaze according to any one of claims 1 to 4, characterized in that: The manufacturing method specifically comprises the following steps: (1) first preparing a modified resin, mixing and dissolving the prepared modified resin with ore powder, nano-oxide powder, and negative oxygen ion powder in an organic solvent, and controlling the temperature during dissolution to be 150-200° C., mixing and stirring in a high-speed stirrer at 1500-1600 rpm, and applying ultrasonic treatment with a power of 100 W throughout the process; (2) Add dispersant, defoaming agent, film-forming aid, ultraviolet absorber and leveling agent, stir and disperse at high speed to obtain glaze.

6. The method for manufacturing the negative oxygen ion ceramic surface glaze according to claim 5, characterized in that: The preparation process of the modified resin powder comprises the following steps: (1) mixing and dissolving bisphenol A epoxy resin powder with a molecular weight of 5000-8000 and polyether polyurethane oligomer with an isocyanate terminal in a tetrahydrofuran solution, and controlling the temperature in the reactor to 210-225° C. and the pressure to 1.35-1.55 MPa; (2) Then, a curing agent is added and mixed, and infrasonic and ultrasonic treatments are applied during the reaction process. After solidification, the product is taken out, crushed and sieved to obtain modified resin powder.

7. The method for manufacturing a negative oxygen ion ceramic surface glaze according to claim 1, characterized in that: The mass ratio of the bisphenol A epoxy resin to the polyether polyurethane oligomer with isocyanate at the end is 3:1.
