Description

Texture forming method of decorative brick and decorative brick

Technical Field

The invention relates to a decorative brick pressed by a brick press, in particular to a method for forming textures of the decorative brick.

Background

In the prior art, decorative bricks, such as polished ceramic bricks, which are pressed by a brick press, adopt a process of distributing powder on the surface of the powder for multiple times to form the texture effect on the surface of a brick body. The texture formed is relatively solidified and mechanized, and is easy to be uniform.

Disclosure of Invention

The invention aims to provide a texture forming method of a decorative tile so as to form a texture rich in variation. It is another object of the present invention to provide a decorative tile having a rich texture.

The method of the invention is realized as follows: filling various powders into a mould of a brick press, enabling the various powders in the mould to be non-uniformly mixed, thereby forming a plurality of blocks consisting of different powders, then pressing the powders in the mould by the brick press to prepare a green brick matrix, and then dividing a green brick from the green brick matrix, wherein a cutting surface is used as a decorative surface of the green brick.

As an alternative embodiment, one of the methods for non-uniformly mixing the multiple powders in the mold is to distribute the powders in layers along the height direction of the mold, so that at least part of the powders in the mold form a longitudinal layered structure, each layer of powders is a block, and during distribution, after a groove is scraped on the surface of the lower layer of powders which is just laid, a layer of powders is laid, so that the upper layer of powders permeates into the lower layer of powders.

As an alternative embodiment, one of the methods for non-uniformly mixing the powders in the mold is to distribute the powders in layers along the transverse direction of the mold, so that at least part of the powders in the mold form a transverse layered structure, and each layer of the powders is a block.

In the transverse layered structure, an outer layer surrounds an inner layer and is nested layer by layer.

As an alternative, in the transverse layered structure, there are both a structure in which the layers are arranged side by side and a structure in which the outer layer surrounds the inner layer, nested layer by layer.

As alternative embodiments, there are two methods for non-uniformly mixing the multiple powders in the mold, one is a material distribution method of distributing materials layer by layer along the height direction of the mold, so that part of the powders in the mold form a longitudinal layered structure; and secondly, forming a transverse layered structure of partial powder in the die along the distribution mode of transverse layered distribution of the die, and finally forming a combination of a longitudinal layered structure and a transverse layered structure of the powder in the same die, wherein each layer of the powder is a block no matter the longitudinal layered structure or the transverse layered structure.

As an alternative embodiment, before the distributing manner of the transverse layered distribution is implemented, a vertical partition plate is placed in the mold at the interface of every two layers of powder corresponding to the transverse layered structure, and after the powder is filled into the space between the partition plates, all the partition plates are taken out of the mold.

As an alternative embodiment, the partition is an orifice plate with through-holes.

As an alternative, one of the methods for non-uniformly mixing the powders in the mold is to mix the different powders together with a light agitation, which means that the agitation is not enough to eliminate all the blocks, so that the blocks still exist after the different powders are mixed with the agitation.

Alternatively, after the powder in the mold is pressed by the brick press, the pressed product is cut, and the cut pieces are assembled into the green body.

The decorative brick is realized by the following steps: the texture pattern on the decorative surface of the decorative tile is formed by the method, and the whole decorative tile has texture formed by the plurality of blocks and the interfaces among the blocks.

The invention has the advantages that: the plurality of blocks formed by the non-uniformly mixed powder enables the cutting surface formed by cutting the green brick matrix to have varied textures, and the green bricks cut from the green brick matrix naturally have varied texture patterns by taking the cutting surface as a decorative surface. Compared with the existing green brick texture forming method, the formed texture is richer and more natural, and texture patterns which are difficult to reach in the prior art and almost infinitely variable can be obtained by changing the mixing mode of powder and matching with different cutting angles of a green brick matrix. The method of the invention is not only suitable for decorative bricks which need to be fired at high temperature, such as ceramic tiles, but also suitable for baking-free bricks which do not need to be fired at high temperature, such as decorative bricks which use cement as a binder. The decorative brick provided by the invention has the texture formed by the plurality of blocks and the interfaces among the blocks together, and the texture can be maintained to any extent no matter how much the decorative brick is worn, so that the decorative brick is durable.

Detailed Description

In order to facilitate an understanding of the present invention, a more complete description of the present invention is provided below. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Example one

According to the texture forming method of the decorative brick, a plurality of powders are filled in a mold of a brick press, and the powders in the mold are non-uniformly mixed, so that a plurality of blocks which are composed of different powders and are shown in fig. 1 are formed. Each curve in FIG. 1 represents an interface between two different blocks, the different blocks being composed of different powders. The preparation method of the powder can adopt the prior art.

It should be noted that the present invention does not require that the powder of the same block is only a single powder. The powder in the same block can be single powder or formed by mixing multiple powders. However, two different blocks adjacent to each other should be composed of different powders. The different powder materials comprise powder materials with different colors and particle sizes or powder material mixtures with different proportions.

The green body 1 shown in fig. 2 is produced by pressing the powder having the partition structure shown in fig. 1 with a brick press under high pressure. Each curve segment in fig. 2 represents an interface between two different blocks. Subsequently, a block of green brick is separated from the green brick matrix 1. The cutting surface is the front surface of each green brick, namely the decorative surface of the green brick. Fig. 3 schematically illustrates three different angled cut surfaces of the green body 1, indicated by planes P1, P2, P3, respectively. Different texture patterns can be cut by the cutting surfaces with different angles. Even if the cutting surfaces are at the same angle, the texture patterns on the cutting surfaces formed by cutting once are different, so that abundant and natural texture patterns are obtained. It should be noted that the cutting surface for dividing the green body is not limited to a flat surface, and the green body may be cut along a curved surface, so that a decorative tile having a curved surface can be produced.

When the green brick matrix is cut, the green brick matrix can be taken out of the mold of the brick press and then cut, or can be directly cut in the mold of the brick press.

After the green bricks are separated from the green brick matrix, the subsequent processing technology of the green bricks can adopt the prior art, thereby finally preparing the required decorative bricks. The decorative tile body is manufactured to have the texture formed by the plurality of blocks and the interfaces among the blocks together, and not only has the texture on the decorative surface of the tile body.

The shape of the green brick matrix is not limited to fig. 2, and may be other shapes such as a cylindrical shape.

Example two

The method for non-uniformly mixing multiple powders in the mold can adopt the existing layered distribution process, namely, the materials are distributed in layers along the height direction of the mold to form a longitudinal layered structure shown in fig. 4, and each layer of powder is a block. Specifically, powder is paved layer by layer in the mould by a material distributing vehicle, and the number of the paved powder layers is determined according to the actually needed texture effect. It should be noted that the thicknesses of the powders in the respective layers are not necessarily uniform, and the thicknesses of the powders in the same layer are not necessarily uniform. In the material distribution process, a layer of powder can be laid after a groove is scraped on the surface of the lower layer of powder which is just laid, so that the upper layer of powder permeates into the lower layer of powder, and the interface of adjacent blocks interpenetrates with each other. In this way, the texture on the cutting surface cut from the green brick matrix has the natural effect of mutually penetrating and transiting the blocks. The shape, depth and number of the grooves are determined according to the actually required texture effect. The process method can be to lay a layer of powder after the surface of each layer of powder is scraped with a groove, or to perform the operation only on one or a plurality of layers of powder.

EXAMPLE III

The method for non-uniformly mixing the powder materials in the mould can also be a method for distributing the powder materials in a transverse layered manner along the mould to form a transverse layered structure. FIG. 5 is an example of a powder material forming a transverse layered structure. As shown in fig. 5, the powder filled into the mold is formed in a structure in which layers are arranged side by side, and each layer of powder is a block. It should be noted that the interfaces between the layers may be flat or curved, and the interfaces arranged side by side are not necessarily parallel to each other, and the intervals between the interfaces are not necessarily the same.

Fig. 6 shows another example of a lateral hierarchical structure. FIG. 6 is a powder layering structure in a mold, as seen from a top view of the mold. As shown in fig. 6, the powder forms a structure in which the outer layer surrounds the inner layer and is nested layer by layer, and each layer of powder is a block. Except that the powder of the most central layer is equivalent to a solid upright column body, each other layer of powder is equivalent to a hollow upright column body, and the upright column body of the outer layer surrounds the upright column body of the inner layer and is nested layer by layer. The cross section of each of the upright columns is not limited to the illustrated oval shape, and may be other shapes such as a triangular shape, and may be designed arbitrarily.

Different transverse layered cloth modes can be combined together to form a structure with layers arranged side by side and a layered structure with an outer layer surrounding an inner layer and nested layer by layer. For example, as shown in fig. 7, it can be seen from the top view of the mold that the powder charged into the same mold by the horizontal layered distribution method has a structure in which the layers are arranged side by side like fig. 5, and a structure in which the outer layer surrounds the inner layer and is nested layer by layer like fig. 6.

In order to facilitate the horizontal layered distribution, before the horizontal layered distribution is implemented, a vertical partition plate is placed in the mold corresponding to the interface of every two layers of powder in the horizontal layered structure, the powder is filled into the interval between the partition plates, and then all the partition plates are pulled out of the mold. When the partition plate is extracted, the mixing degree of the powder of the two adjacent layers at the interface can be changed by changing the extraction action speed, so that different interlayer mixing effects are formed.

The partition should conform to the shape of the interface between each two layers of powder in the transverse layered structure. For example, for the lateral layered structure shown in fig. 6, the shape of the separator shown in fig. 8 should be adopted. Each of the vertical hollow thin-walled upright columns with oval cross-section in fig. 8 is a partition. The hollow thin-walled upright columns of different diameters correspond to the elliptical interfaces of the corresponding diameters in fig. 6.

As an alternative embodiment, the partition is an orifice plate with through-holes. Therefore, powder materials of adjacent layers can permeate into each other through the through holes to form a certain interlayer mixing effect. Different interlayer mixing effects can be achieved by designing different shapes, sizes, numbers and distribution positions of the through holes, and finally different textures are formed. It should be noted that the orifice plate of the present invention also includes a wire mesh.

Example four

The method for non-uniformly mixing various powder materials in the die can also be a material distribution mode of layering material distribution along the height direction of the die and a material distribution mode of transverse layering material distribution along the die, and a combination of a longitudinal layered structure and a transverse layered structure is formed in the same die. For example, as shown in fig. 9, three layers of powder near the bottom of the mold are distributed in layers along the height direction of the mold to form a longitudinal layered structure similar to that shown in fig. 4; the powder of the other layers is distributed in a transverse layered mode to form a transverse layered structure similar to that in the figure 7.

EXAMPLE five

The method for non-uniformly mixing various powders in the die can be a method of distributing materials in layers, and different powders can be stirred and mixed together slightly, wherein the slightly stirring and mixing means that the stirring degree is not enough to eliminate all blocks, so that a plurality of blocks formed by different powders still exist after the powders in the die are stirred and mixed. Specifically, the various powders may be poured separately into the mold to form individual blocks, and then the powders within the mold may be gently mixed with agitation so that the different blocks are slightly mixed while the presence of the blocks remains. Or the powder in the container can be poured into the mould after a plurality of powder materials are poured into the same container respectively. The process of pouring the powder in the container into the mould is a process of slightly stirring and mixing the powder, and the powder naturally forms a plurality of blocks in the mould.

The present embodiment is characterized in that unlike the previous embodiments, the present embodiment has a relatively clear interface, and the interface between adjacent blocks is relatively fuzzy, which can generate a texture effect of completely random natural variation transition between blocks.

EXAMPLE six

After the powder in the mould is pressed by the brick press, the pressed product is not needed to be directly used as a green brick matrix as in the first embodiment, but the pressed product can be cut firstly, and then the cut blocks are spliced into the green brick matrix. This allows for more flexible and varied combinations of textures. As a method for combining the blocks into a green body, for example, an adhesive, specifically, cement, tile glue or the like can be used. The processing method after the green brick matrix is manufactured is the same as the first embodiment, and the description is omitted.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. The protection scope of the present invention should be subject to the appended claims.
