Method for manufacturing extrusion molding sculptured natural glazed wood grain bricks

Abstract

The invention relates to a method for manufacturing extrusion molding sculptured natural glazed wood grain bricks. Natural wood grain bricks with very realistic effects can be manufactured, and the bricks can be manufactured under the conditions that the moisture content of the green brick is larger than 16 percent and the diameter of a wood grain carving roller is larger than the green brick cutting length. The method comprises the following manufacturing steps: 1. pressing the green brick by virtue of a stereoscopic carving sculptured wood grain roller so as to enable the texture of the pressed green brick to have the texture and sculpture which are consistent with those of the original wood plate xylem and thin-walled rays; and 2. cutting each green brick into a green brick with the needed length after pressing, and drying in a drying kiln so as to reduce the moisture of the green brick to be 1 percent or below, applying matt or dull glaze with contrast from the color of the green brick of the ceramic tiles on the surface of the green brick, erasing the glaze on the protruding part of the glazed body, remaining the glaze in the concave texture, filling the glaze, firing the tiles in a kiln so as to form contrast between the color of the green brick and the color of the embossing, thereby obtaining the wood grain ceramic bricks. The process is ingenious, the green brick has clean patterns, and contrast is formed between the color of the green brick and the color of the embossing. Therefore, natural wood grain ceramic bricks of which the patterns are different from one another are obtained.

Description

technical field [0001] The invention relates to a production method of extrusion molding imitation relief natural glazed wood grain brick. Background technique [0002] With the continuous development of society, people have higher and higher requirements for ceramic tiles. However, wood grain bricks have always been pursued and favored by people. Now there are three types of wood grain bricks on the market. One is dry pressed by a press. The wood-grain tiles are wood-grain tiles that are printed or ink-jet printed; the other is wood-grain tiles that are extruded from two or more color-contrasting raw materials through an extruder; the other is printed or ink-jet printed wood grain tiles. The wood-grain tiles dry-pressed by the press cannot form the thin-walled ray effect of natural wood because the moisture content of the spray material is below 8%, and the texture pressed by the press is realized by the press mold. The texture of the patterned bricks is consistent, which...

Problems solved by technology

The wood-grain tiles dry-pressed by the press cannot form the thin-walled ray effect of natural wood because the moisture content of the spray material is below 8%, and the texture pressed by the press is realized by the press mold. The texture of the patterned bricks is consistent, which cannot achieve the effect of natural wood grain textures. In addition, after pressing, whether it is printing or inkjet printing, a layer of glaze is required to decorate through the patterns on the glaze surface. Such glazed tiles are not wear-resistant. After decoration, it is easy to grind or wear off the glaze, which will affect the decorative effect and have a limited service life; the wood-grained bricks made by extrusion molding through color contrast have the same wood core grain effect, which cannot highlight the xylem and wood of precious wood. The mechanism of thin-walled rays, the decoration is also very limited, and the whole body is colored, and a layer of skin needs to be thrown off the surface, which is extremely wasteful and costly; ceramic tiles that are directly printed or inkjet printed are limited by the fixing of flower nets and rollers As well as the limitations of inkjet printing documents, the tiles produced have the same pattern and the same effect, which cannot achieve the effect of natural texture.
