Transparent glaze for calligraphy plaque and use thereof in enamel calligraphy plaque

Abstract

A transparent glaze for a calligraphy plaque, mainly composed of the following raw materials in parts by weight: 6-8% of B2O3, 19-20% of Na2O, 4-5% of Al2O3, 40-41% of SiO2, 20-21% of PbO, 7.5-8.0% of TiO2, and 1-1.2% of MoO3. In the formula, the content of titanium is reduced to reduce the opalescence of porcelain glaze, thereby improving the transparency; in addition, the content of sodium oxide is increased to reduce the melting point, so that the transparent glaze can be formed by low-temperature firing, and the impact of high-temperature firing on the calligraphy content at the bottom is reduced as much as possible. Moreover, an enamel calligraphy plaque prepared using the transparent glaze for a calligraphy plaque has a fine and smooth porcelain surface, high transparency, good flatness, a strong sense of layering, and a very strong visual effect.

Description

A transparent glaze for calligraphy plaques and its application in enamel calligraphy plaques Technical Field

[0001] The invention belongs to the technical field of new materials and relates to a glaze slurry for calligraphy plaques, in particular to a transparent glaze for calligraphy plaques and an application thereof in enamel calligraphy plaques. Background Art

[0002] In the past, plaques were basically made of wood, paper frames, aluminum-plastic panels, etc. These materials have disadvantages such as being difficult to preserve, difficult to clean, easy to deform, and easy to fade. Summary of the Invention

[0003] In view of this, the present invention provides a calligraphy plaque transparent glaze and application of the glaze in enamel calligraphy plaques.

[0004] It should be noted that compared with traditional plaques, enamel calligraphy plaques have the excellent properties of enamel, such as good weather resistance, wear resistance, scratch resistance, high hardness, corrosion resistance, bright colors and no fading, easy to clean, etc.; compared with traditional enamel products, it has the cultural attributes given to it by artistic calligraphy and painting; the two are combined and complement each other, and the fusion of two traditional things can better reflect the beauty of Chinese classical culture.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The first technical purpose of the present invention is to provide a transparent glaze for calligraphy plaques, which is mainly composed of the following raw materials in parts by weight: B2O3 6-8%; Na2O 19-20%; Al2O3 4-5%; SiO2 40-41%; PbO 20-21%; TiO2 7.5-8.0%; and MoO3 1-1.2%.

[0007] It is worth noting that the present invention reduces the titanium content to reduce the opacity of the porcelain glaze itself and increase its transparency, while increasing the sodium oxide content to lower the melting point so that it can be fired at low temperature, minimizing the impact of high-temperature firing on the calligraphy content on the bottom.

[0008] Moreover, various effects of the upper layer of porcelain glaze on the plaque can be designed according to the content of the calligraphy. For example, the surface of the plaque in a downtown scenic area needs to be bright and shiny, so it can be sealed with a high-gloss glaze layer; the plaque in a temple can be sealed with a matte and low-lying glaze layer; the plaque in a small cottage in the woods can be sealed with a relief-layered glaze layer; the upper layer of glaze will not snatch away the connotation and temperament of the calligraphy, but can further enhance the cultural conception of the entire plaque through the combination of gloss and spatial levels; it can also highlight the matte and low-lying text content on the shiny porcelain plate, and the text can be clearly seen with different light; the shapes are complex and diverse, although they are inconsistent with traditional cultural plaques, but plaques of various complex shapes can also be made, which are easy to adapt to the ever-changing appreciation tastes.

[0009] The second technical purpose of the present invention is to provide a calligraphy plaque transparent glaze for use in enamel calligraphy plaques.

[0010] Optionally, the enamel calligraphy plaque is made by spraying the calligraphy plaque transparent glaze on an enamel calligraphy base plate, followed by drying and firing.

[0011] Furthermore, the spraying thickness of the calligraphy plaque transparent glaze is 30-60 μM, the firing temperature is 790° C., and the firing time is 4 minutes.

[0012] Furthermore, the spraying process parameters are as follows:

[0013] Glaze slurry bulk density is 140~155g / cm 3 , the spraying air pressure is 0.3-0.6Mpa, and the gun distance is 250-500mm.

[0014] Furthermore, the glaze slurry is composed of the following raw materials in parts by weight:

[0015] 100 parts of calligraphy plaque transparent glaze, 0.1 parts of methyl cellulose, and 50 parts of water.

[0016] The beneficial effects of the present invention are as follows: the enamel calligraphy plaque prepared by using the calligraphy plaque transparent glaze of the present invention has a delicate porcelain surface, high transparency, good flatness, strong layering, and strong visual effect.

[0038] Experimental Example 1

[0039] The formula of calligraphy plaque transparent glaze KE009 includes the following components:

[0040] B2O37.5%; Na2O 19%; Al2O34%; SiO240%; PbO 21%; TiO28.0%; MoO31%;

[0041] Test materials: Enamel calligraphy base plate special transparent glaze KE009 enamel plate transparent glaze 6108

[0042] Test process:

[0043] 1. Glaze slurry preparation

[0044] The enamel base is made by using an electrostatic dry method to paint calligraphy ink on a white board. Two types of transparent glaze are sprayed on the base, and the samples are fired for comparative testing:

[0045] (1) The preparation formula of wet glaze slurry 1 is

[0046] KE009100% methylcellulose 0.5% water 50%; grinding coarseness is 0.05-0.1g (140 mesh sieve residue), making the porcelain surface more delicate;

[0047] (2) The preparation formula of wet glaze slurry 2 is:

[0048] 6108100% MCV0760.6% 30202% Sodium nitrite 0.3%

[0049] Water: 50%; grinding coarseness is 0.1-0.2g;

[0050] 2. Spraying and making the base plate

[0051] The prepared glaze slurry was sprayed on the enamel calligraphy base plate with a thickness of 30-60 μM. After drying, the firing process was set at 790°C for 4.0 min to obtain the enamel calligraphy plaque plate. The porcelain surface effect was observed and compared.

[0052] Spraying precautions:

[0053] The bulk density of glaze slurry is controlled within 140g / cm 3 ~155g / cm 3 ;

[0054] To prevent the orange peel wrinkle problem under the condition of partial pouring of glaze slurry, the spraying process is adjusted accordingly. The gun distance remains unchanged, but the air pressure setting is changed to 0.3-0.6Mpa:

[0055] Test data and analysis:

[0056] The bulk density of glaze slurry is controlled at 140g / cm 3 ~155g / cm 3 When spraying, the No. 2 glaze slurry is more drippy and some sagging occurs during spraying.

[0057] 3. When the thickness of the porcelain layer is 30-60μm, the transparency of the No. 1 porcelain layer is significantly stronger than that of No. 2, and the thicker parts of No. 2 are partially covered with white.

[0058] It can be seen that the transparency and operating performance of the enamel calligraphy plaque special porcelain glaze KE009 are significantly better than the existing silk screen enamel transparent glaze. Combined with the adjusted process, a more excellent enamel calligraphy plaque can be produced. Experimental Example 2: Calligraphy text color matching ratio

[0059] In order to make the background of the plaque coordinate with the environment, it is necessary to adjust the pigment ratio in time to make the color harmonious with the surrounding environment; the pigment ratio can also be adjusted to make the sample color brighter or more stable to meet customer needs. Adjust the ratio of oil to pigment (1:0.8) to make the color thinner and more transparent; you can also adjust the ratio of oil to pigment (1:0.5) to make the color thicker; you can also add other concave and convex oils and adjust the ratio to make the layer show a concave and convex effect, enhancing the three-dimensional sense of the pattern;

[0060] The enamel calligraphy plaques produced according to this process have a delicate surface, high transparency, good flatness, strong sense of layering, and a strong visual effect.

[0061] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
