[0004] To solve the above-mentioned technical problems, this application is implemented as follows:
[0005] In a first aspect, embodiments of this application provide a method for preparing a binder for pigments, comprising:
[0006] Frankincense resin and olive oil are stirred at a temperature of 120℃-130℃ to dissolve the frankincense resin, thereby obtaining a first mixture; the components of the first mixture, by mass percentage, include: 70%-80% of the olive oil and 20%-30% of the frankincense resin.

[0022] Figure 3 This is the second flowchart of a pigment preparation method provided in the embodiments of this application. Detailed Implementation
[0023] The technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] To better understand the technical solutions of the embodiments of this application, the relevant content of this application will be described below.
[0025] Ceramic painting is a ceramic decoration technique that involves painting on a fired white clay body. After painting, the white clay body is fired again at high temperature to form the finished product. Because the paint adheres to the glaze, this ceramic decoration technique is also called overglaze painting. In ceramic art creation, overglaze painting is widely used to decorate various objects. Related techniques require the artificial preparation of pigments for ceramic painting. Specifically, the pigments are mainly obtained by manually mixing ceramic color powder with frankincense oil, diluting it with camphor oil, and then grinding it manually. However, the binders currently used for pigments are quite dark, and the mixing of ceramic color powder and binder has a significant impact on the color of the pigments.
[0026] This application provides a method for preparing a binder for pigments to solve the problem of the binder for pigments having a heavy color.
[0027] See Figure 1 The present application embodiment describes a method for preparing a binder for pigments, comprising:
[0028] Step 101: Stir the frankincense resin and olive oil at a temperature of 120℃-130℃ to dissolve the frankincense resin and obtain a first mixture; the components of the first mixture by mass percentage include: 70%-80% of the olive oil and 20%-30% of the frankincense resin.
[0029] Step 102: Add 1%-2% of activated clay by mass of the first mixture to the first mixture to obtain the second mixture;
[0030] Step 103: Stir the second mixture;
[0031] Step 104: Remove the activated clay from the second mixture to obtain the adhesive.
[0032] In this embodiment of the application, in order to make the adhesive lighter in color, the frankincense resin can be selected from high-quality frankincense resin particles with a lighter color, and impurities in the frankincense resin are removed in advance by vibrating sieve.
[0033] In step 101, 20-30% by mass of frankincense resin and 70-80% by mass of olive oil are stirred at a temperature of 120°C-130°C to dissolve the frankincense resin. In this embodiment, to ensure complete dissolution of the frankincense resin, stirring can be continued at the above-mentioned high temperature for more than 1 hour, for example, 1-2 hours. Heating and stirring the frankincense resin and olive oil in this embodiment is environmentally friendly, healthy, and odorless. Furthermore, in this embodiment, by setting the olive oil content to 70%-80% and the frankincense resin content to 20%-30% in the first mixture, the final adhesive has a better bonding effect, thereby improving the adhesion of pigments added to the adhesive.
[0034] In step 102, activated clay has the function of adsorbing color. Activated clay is added to the first mixture to obtain the second mixture. The color of the second mixture is lighter than that of the first mixture.
[0035] In step 103, by stirring the second mixture, the activated clay can fully adsorb the color of the second mixture. Furthermore, to achieve a better adsorption effect, the stirring speed and stirring time can be increased, for example, the second mixture can be stirred at high speed for 1 to 2 hours.
[0036] In step 104, after the bleaching clay has fully absorbed the color of the second mixture, the bleaching clay is removed from the second mixture to obtain a light-colored oily adhesive containing olive oil and frankincense resin. In this embodiment, the bleaching clay in the second mixture can be removed in various ways, such as by filtration, precipitation, or centrifugation.
[0037] The embodiments of this application can obtain a light-colored adhesive through the above preparation steps, which can reduce the influence of the adhesive on the color of the pigment.
[0038] Optionally, see Figure 2 Add 1%-2% by mass of activated clay to the first mixture, comprising:
[0039] After the first mixture is cooled, 1%-2% of activated clay by mass of the first mixture is added to the first mixture.
[0040] In this embodiment, the cooling of the first mixture can be achieved through natural cooling or by using other cooling equipment. In this embodiment, adding activated clay after the first mixture has cooled can avoid affecting the activity of the clay, thereby ensuring the adsorption effect of the clay.
[0041] Optionally, the removal of activated clay from the second mixture includes:
[0042] The second mixture was left to stand, and the activated clay was removed from the second mixture after standing using a centrifuge.
[0043] In this embodiment, allowing the second mixture to stand allows sufficient time for the components to settle or disperse, enabling them to stratify or separate uniformly. After standing the second mixture, centrifuging is used to remove the bleaching clay, which improves the removal efficiency. In this embodiment, to achieve better centrifugation results, the standing time can be more than 4 hours; for example, 4-6 hours is acceptable.
[0044] This application also provides an adhesive for pigments, which is prepared by any of the above-described adhesive preparation methods.
[0045] Optionally, the adhesive has a solids content of 10%-20%.
[0046] In this embodiment, the solid content of the adhesive is 10%-20%, which is beneficial to improve the adhesive effect of the adhesive and makes the pigment with added adhesive have stronger adhesion. After the pigment dries on the white body, it adheres to the glaze surface. After high-temperature firing, there is no bubbling, no odor, and it is environmentally friendly and healthy.
[0047] It should be noted that the specific implementation methods of the adhesives in the embodiments of this application can refer to the above description and can achieve the same technical effect. In order to avoid repetition, the comparison will not be repeated.
[0048] In related technologies, ceramic painting pigments are obtained by manually mixing ceramic color powder with a binder, diluting it with camphor oil, and then manually grinding it. It is evident that ceramic painting pigments in these technologies suffer from inconvenience due to the manual mixing and grinding process.
[0049] To address the inconvenience of manually mixing and grinding ceramic painting pigments, see [link to relevant documentation]. Figure 3 This application also provides a method for preparing a pigment, comprising:
[0050] Step 201: Mix the various materials to obtain a third mixture;
[0051] Step 202: Add the third mixture to a mill and grind it to obtain pigment;
[0052] The third mixture includes:
[0053] 50-60 parts by weight of adhesive, wherein the adhesive is any one of the adhesives in the above embodiments;
[0054] 40-50 parts by weight of ceramic pigment.
[0055] In this embodiment, the binder and ceramic pigments in the above-mentioned weight proportions are mixed and ground to obtain a pigment for ceramic painting. This pigment can be used directly for painting, making it convenient to use immediately. Furthermore, the binder in this embodiment has the characteristics of light color and strong adhesion. Therefore, the pigment prepared by the method of this embodiment also has the beneficial effects of good coloring effect, strong adhesion after firing, and no bubbling or shrinkage after firing when applied thickly at 2mm.
[0056] It is worth noting that the pigments in this embodiment can be used immediately or after dilution. Related technologies using camphor oil for dilution produce a strong, pungent odor that can negatively impact health. Therefore, in this embodiment, the pigments can be diluted with odorless turpentine during use, overcoming the drawback of the pungent odor and achieving environmental friendliness and health benefits.
[0057] Optionally, such as Figure 2 As shown, the third mixture also includes:
[0058] 30-40 parts by weight of transparent glaze.
[0059] In this embodiment, by adding the aforementioned amount of transparent glaze by weight, the transparency of the prepared pigment can be increased, thereby improving the painting effect.
[0060] Optionally, such as Figure 2 As shown, the third mixture also includes:
[0061] Dispersant 0.2-0.5 parts by weight;
[0062] In this embodiment, by adding the above-mentioned amount of dispersant by weight, the color of the prepared pigment can be more uniform, thereby improving the painting effect.
[0063] Optionally, adding the third mixture to the mill for grinding includes:
[0064] The third mixture is added to a mill and ground until the particle size is less than or equal to 10 micrometers.
[0065] This application does not limit the specific type of mill. For example, to achieve a better milling effect, the mill may be a three-roll mill.
[0066] In this embodiment of the application, by adding a third mixture comprising 50-60 parts by weight of binder, 40-50 parts by weight of ceramic pigment, 30-40 parts by weight of transparent glaze and 0.2-0.5 parts by weight of dispersant to a mill and grinding it to a particle size of less than or equal to 10 micrometers, an oil-based paste painting pigment can be obtained. This oil-based paste painting pigment has the following advantages over solvent-based pigments in related technologies: strong adhesion after firing, no bubbling or cratering after firing when the thickness is 2mm, no irritating odor, no deterioration after 24 months of storage, high transparency, particle size not greater than 10μm and flowability not greater than 4cm.
[0067] This application also provides a pigment, which is prepared by any of the pigment preparation methods described above. Specific implementation methods of the pigment in this application can be referred to the above description and can achieve the same technical effects; therefore, to avoid repetition, they will not be elaborated further.
