Description

Technical Field

[0001] The invention belongs to the technical field of wax painting technology, and in particular relates to a wax painting technology for ceramic products. Background Art

[0002] Batik is a traditional Chinese folk printing and dyeing technique - a type of indigo dyeing. Its principle is to use wax to seal fabric fibers to prevent dye from penetrating and forming patterns. During the dyeing process, the wax naturally cracks and forms natural "ice patterns". With the advancement of the times and the development of technology, traditional batik techniques are no longer restricted to fabric media, but are instead applied to a variety of media including cotton, linen, ceramics, leather and other items.

[0003] In a Chinese patent with publication number CN105856399A, a wax painting process for ceramic products is mentioned, including S1, dissolving wax; S2, painting patterns on blanks; S3, coloring; S4, brushing glaze into kiln; S5, cooling out of kiln. The steps of the present invention are simple. The fluid properties and anti-staining properties of the wax liquid itself are mainly used to form wax liquid flow patterns that are difficult to draw artificially on the basis of the preset pattern when the wax liquid is painted on the surface of the ceramic blank. At the same time, a method of carving wax patterns on the cooled wax liquid with a knife can be used to make the wax painting pattern more natural and realistic. When the wax liquid is cooled, the area covered by the wax liquid will prevent and hinder the entry of pigments during coloring, so that wax patterns are formed at the pattern drawn by the wax liquid. Then, the wax painting pattern is made more firm through the steps of coloring, brushing glaze into the kiln and cooling out of the kiln. The ceramic products treated by the process of the invention have the advantages of realistic patterns, firm colors and not easy to discolor.

[0004] During the application process, the applicant discovered that the above application had defects during use. When making batik ceramic products, the process disclosed in the application requires first using wax liquid to draw a preset pattern on the surface of the ceramic blank, and then coloring, glazing and firing. At this time, the wax liquid on the surface of the blank is not removed. The wax liquid will be wrapped by the ceramic glaze and sandwiched between the blank and the ceramic glaze, making it difficult to evaporate under high temperature conditions, which in turn makes it impossible to remove the ceramic glaze pigment on the area coated with wax liquid, and it is impossible to form the missing pattern of the wax painting process, which ultimately makes the wax painting pattern on the finished ceramic product blurred, and it is impossible to form a clear color contrast between the colored area and the waxed area. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a wax painting process for ceramic products to solve the problem that on existing wax-painted ceramic products, the wax liquid will be wrapped between the blank and the ceramic glaze, making it impossible for the pigment and the wax liquid to be discharged, thereby causing the boundary between the wax painting area and the colored area on the ceramic surface to be blurred and the contrast to be unclear.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A wax painting process for ceramic products, comprising the following steps:

[0008] S1, cutting the film to be torn off according to a preset pattern to obtain a pattern sample film, using the pattern sample film as an interlayer to cover the melted wax liquid, and forming a pattern wax patch after the wax liquid is cooled;

[0009] S2, attaching the pattern wax patch to a preset position on the surface of the ceramic blank, heating and softening the pattern wax patch, so that the softened pattern wax patch is deformed and attached to the surface of the ceramic blank, and after the wax on the pattern wax patch is cooled, a ceramic blank with a pattern wax patch is obtained;

[0010] S3, covering the surface of the ceramic blank with the pattern wax patch with a ceramic glaze pigment to obtain a colored blank;

[0011] S4, after the ceramic glaze pigment on the surface of the colored blank is dried, the pattern wax patch on the surface of the colored blank is heated and melted to expose the pattern sample film inside the pattern wax patch, and the entire pattern wax patch is peeled off through the pattern sample film to obtain a colored blank with an uncolored pattern gap;

[0012] S5, brushing or spraying ceramic glaze on the surface of the colored blank with the uncolored pattern gap, and putting the glazed blank into a kiln and firing it at a constant temperature of 900° C. to 1300° C. for 6-8 hours;

[0013] S6, turning off the fire, cooling and taking out of the kiln to obtain wax-painted ceramic products.

[0014] Preferably, the film to be torn includes PU film, PET film and TPE film.

[0015] Preferably, the surface of the film to be torn has perforations through which the ceramic glaze pigment can pass.

[0016] Preferably, rosin and resin are added to the melted wax liquid to increase the adhesion of the wax liquid.

[0017] Preferably, when heating and softening the pattern wax patch, a portion of the pattern wax patch is heated first, so that the softened portion of the pattern wax patch is seamlessly bonded to the surface of the ceramic blank, and then the adjacent portion of the softened bonding portion of the pattern wax patch is heated to soften and bond the pattern wax patch from near to far, so that the entire pattern wax patch is seamlessly bonded to the surface of the ceramic blank.

[0018] Preferably, the ceramic glaze pigment covering methods include dipping, brushing and spraying.

[0019] Preferably, the ceramic glaze pigments include water-based dyes, iron oxide dyes and metal salt dyes.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention forms a pattern sample film by cutting the to-be-torn film into a preset pattern, and using the pattern sample film as an interlayer to cover the melted wax liquid. After the wax liquid is cooled, a pattern wax patch is formed. When a wax drawing pattern needs to be formed on a ceramic product, the pattern wax patch is softened and pasted on a ceramic blank, and then the ceramic blank is overall colored. Some ceramic glaze pigments are sprayed on the pattern wax patch. After the ceramic glaze pigments are dried and solidified on the surface of the ceramic blank, a part of the pattern wax patch is melted to expose the to-be-torn film inside the pattern wax patch, and the entire pattern wax patch is torn off through the to-be-torn film. The pattern wax patch forms an uncolored gap in the shape of the pattern wax patch on the surface of the ceramic blank, and then glazes and fires it to form a wax-painted ceramic product. Compared with traditional wax-painted ceramic products, this process can completely remove the wax liquid attached to the surface of the ceramic blank and the ceramic glaze pigment on the surface of the wax liquid, and there will be no situation where the wax liquid and pigment are blocked between the ceramic blank and the ceramic glaze and cannot be removed. The boundary between the dyed area and the undyed area on the surface of the ceramic blank is clearer and brighter, the appearance is better, and a higher quality wax-painted ceramic product is obtained. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figure 1 , a ceramic wax painting process, comprising the following steps:

[0026] S1. Cut the film to be torn according to the preset pattern. The designer can design more complex and varied patterns through computers and other equipment, and then use an intelligent cutting machine to cut the film to be torn into the designed pattern to obtain a pattern sample film. The pattern sample film is used as an interlayer to cover the melted wax liquid. The wax liquid is evenly distributed on both sides of the pattern sample film. After the wax liquid is cooled, a pattern wax patch is formed;

[0027] S2, attaching the pattern wax patch to a preset position on the surface of the ceramic blank, heating and softening the pattern wax patch, so that the softened pattern wax patch is deformed and attached to the surface of the ceramic blank, and after the wax on the pattern wax patch is cooled, a ceramic blank with a pattern wax patch is obtained;

[0028] S3, covering the surface of the ceramic blank with the pattern wax patch with a ceramic glaze pigment to obtain a colored blank, wherein the ceramic glaze pigment covering method includes dipping, brushing and spraying, and the ceramic glaze pigment includes water-based dyes, iron oxide dyes and metal salt dyes;

[0029] S4, after the ceramic glaze pigment on the surface of the colored blank is dried, the pattern wax patch on the surface of the colored blank is heated and melted to expose the pattern sample film inside the pattern wax patch, and the entire pattern wax patch is peeled off through the pattern sample film to obtain a colored blank with an uncolored pattern gap;

[0030] S5, brushing or spraying ceramic glaze on the surface of the colored blank with the uncolored pattern gap, and putting the glazed blank into a kiln and firing it at a constant temperature of 900° C. to 1300° C. for 6-8 hours;

[0031] S6, turning off the fire, cooling and taking out of the kiln to obtain wax-painted ceramic products.

[0032] As can be seen from the above, the film to be torn off is cut into a preset pattern to form a pattern sample film, and the pattern sample film is used as an interlayer to cover the melted wax liquid. After the wax liquid is cooled, a pattern wax patch is formed. When a wax painting pattern needs to be formed on a ceramic product, the pattern wax patch is softened and pasted on the ceramic blank, and then the ceramic blank is colored as a whole. Some ceramic glaze pigments are sprayed on the pattern wax patch. After the ceramic glaze pigment is dried and solidified on the surface of the ceramic blank, a part of the pattern wax patch is melted to expose the film to be torn off inside the pattern wax patch, and the entire film to be torn off is torn off through the film to be torn off. Patterned wax patches are used to form uncolored gaps in the same shape as the patterned wax patches on the surface of the ceramic blank, which are then glazed and fired to form wax-painted ceramic products. Compared with traditional wax-painted ceramic products, this process can completely remove the wax liquid attached to the surface of the ceramic blank and the ceramic glaze pigment on the surface of the wax liquid, and there will be no situation where the wax liquid and pigment are blocked between the ceramic blank and the ceramic glaze and cannot be removed. The boundary between the dyed area and the undyed area on the surface of the ceramic blank is clearer and distinct, the appearance is better, and higher-quality wax-painted ceramic products are obtained.

[0033] The film to be torn off includes PU film, PET film and TPE film, and other films that are soft and not easy to break can also be used to facilitate tearing off the entire pattern wax patch through the film.

[0034] In the traditional batik process, cracks will occur when the wax liquid cools down, and some pigments will adhere to the fabric through these cracks, forming special ice patterns. In order to imitate ice patterns on ceramic products, the surface of the film to be torn off has perforations for the ceramic glaze pigments to pass through. When the pattern wax patch is softened and then dried and shaped on the ceramic product again, the ceramic glaze pigments can pass through the wax pattern gaps and perforations and come into contact with the ceramic product, forming characteristic ice patterns on the surface of the ceramic product.

[0035] The melted wax liquid is added with rosin and resin to increase the adhesion of the wax liquid. The rosin and resin can increase the adhesion of the wax liquid, so that the wax liquid can stably adhere to the film to be torn off, which is convenient for attaching the pattern wax patch to the ceramic product and for subsequently tearing off the entire pattern wax patch through the film to be torn off.

[0036] When heating and softening the pattern wax patch, first heat a portion of the pattern wax patch so that the softened portion of the pattern wax patch is first seamlessly bonded to the surface of the ceramic blank, and then heat the adjacent portions of the softened bonding portion of the pattern wax patch to soften and bond the pattern wax patch from near to far, so that the entire pattern wax patch is seamlessly bonded to the surface of the ceramic blank.
