Description
Technical Field
The invention relates to the technical field of tableware, in particular to a gradual color change molding process of a porcelain-like product.
Background
Melamine products are products which are pressed and formed by taking melamine formaldehyde resin as a matrix and matching with additives such as coloring agents, curing agents and the like, and the appearance of finished products has the luster similar to ceramics and is also called as porcelain-like products. Currently, melamine tableware surface texturing is mainly achieved through a decal process. However, the decal process flow is complex, including the procedures of decal printing, cutting, polishing, drying, decal pressing and the like, and the decal is difficult to increase due to the complexity of the device, so that some decals cannot achieve the ideal effect or even cannot achieve the ideal effect. If the color of the surface of the device is gradually changed, the effect presented by the decal process is stiff and unnatural. Especially, the device shape has concave-convex design, when the decal paper is pasted, the deviation is slight, the gradual change pattern of the decal paper can not accurately correspond to the concave-convex texture of the device shape surface, and the natural smooth color gradual change effect is hardly presented, so that the fineness and the attractive degree of the utensil are affected. In addition, the manufacture of the stained paper is also a consumption of natural resources, and if the use of the stained paper can be reduced, the natural environment can be protected.
Disclosure of Invention
Based on the above, the invention aims to overcome the defects of the prior art and provide a gradual change color forming process of the porcelain-like product.

Referring to fig. 1 to 2, the present embodiment provides a ceramic-like product gradient forming process, which includes the following steps:
step one: firstly, obtaining a first color blank 1 through compression molding, and then obtaining a second color blank 2 through compression molding, wherein the second color blank 2 is made of a material with a certain perspective effect, and the thickness of the second color blank 2 is gradually reduced from the center of the second color blank 2 to the outer edge direction, so that the second color blank 2 presents a transparent effect;
step two: and (3) molding the second color blank 2 on the first color blank 1, performing high-temperature reaction for a preset time, and opening the mold to obtain the porcelain-like product with the visual effect that the inner surface gradually changes from the outer edge to the center color, as shown in fig. 2.
Since the thickness of the second color body 2 is gradually reduced from the center of the second color body 2 to the outer edge, and the second color body 2 has a transparent visual effect, when the second color body 2 is molded on the first color body 1, the color of the second color body 2 fused with the first color body 1 appears, that is, the color of the inner surface of the porcelain-like product gradually changes from the outer edge to the center, and the color of the first color body 1 is more obvious at the outermost edge, and the color of the second color body 2 is more obvious at the inner edge.
The ceramic-like product gradient color forming process provided by the embodiment of the invention abandons the traditional decal process, adopts a brand-new method to realize the gradient color treatment of melamine tableware (ceramic-like products), solves the problem that stained paper lacks natural aesthetic feeling, is not limited by a device, avoids the problem that the melamine tableware adopting the decal process has broken flowers after long-time use and can cause stained paper to change color when heavy oil dishes are contained, and ensures the lasting aesthetic degree of the product; the molding process in the embodiment of the application omits a complicated applique process, shortens the production time and reduces the production cost; moreover, the forming process in the embodiment of the application can avoid the use of stained paper, and is more energy-saving and environment-friendly. And the gradual discoloration is formed by pressing the second color blank body 2 and the first color blank body 1, so that the color patterns are not damaged easily in the cleaning and using processes, and the service life is longer.
Preferably, the thickness of the first color body gradually increases along the direction from the center to the outer edge of the first color body. Thus, the formed gradient color effect is better.
In the first step, the same lower mold is used for both the pressing of the second color blank 2 and the pressing of the first color blank 1, the first color blank 1 is formed by pressing a first upper mold and a lower mold, and the second color blank 2 is formed by pressing a second upper mold and a lower mold, so that the use of the molds can be reduced, and the cost can be reduced. When the porcelain imitation products with different gradient color requirements are required to be manufactured, the first upper die is replaced. Wherein the molding surface of the first upper mold has a first molding surface portion for forming the first color body 1, and the molding surface of the second upper mold has a second molding surface portion for forming the second color body 2.
In the second step, the preset time is 30-60 seconds. Specifically, in the present embodiment, the preset time in the second step is 30 seconds, and of course, in other embodiments, the preset time in the second step may be 40 seconds, 50 seconds, and 60 seconds. The high-temperature reaction is sufficient, and the quality of the prepared porcelain-like product is better.
In this embodiment, the color of the first melamine raw material for manufacturing the first color blank 1 and the color of the second melamine raw material for manufacturing the second color blank 2 have chromatic aberration.
Preferably, the ceramic imitation product gradual change molding process further comprises the following step three: and (3) scattering a proper amount of flash powder on the inner surface of the ceramic imitation product obtained in the step (II), and carrying out mold assembly again and high-temperature reaction for a preset time to obtain the ceramic imitation product with the flash powder on the inner surface, so that the ceramic imitation product has the flash powder and has a better visual effect.
Preferably, the ceramic imitation product gradual change molding process of the embodiment further comprises the following step four: and (3) trimming, grinding and polishing the porcelain imitation product obtained in the step (III) to improve the quality and the fineness of the porcelain imitation product.
The porcelain imitation product in the embodiment can be a product made of melamine materials such as tableware, tea set and the like, the tableware can be a basin, a bowl, a dish, a spoon or the like, and the tea set can be a teapot, a teacup and the like.
The gradual change color on the imitation porcelain manufactured by the forming process is formed by the thickness difference of melamine raw materials, namely, the gradual change color is positioned in the imitation porcelain product, so that the imitation porcelain is not easy to damage, longer in service life, attractive in appearance, stronger in ornamental value and lower in cost.
The above examples merely represent a few embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the inventive manual self-centering vise. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
