Description

Technical Field

[0001] The invention relates to the technical field of artificial stone decorative materials, and in particular to a method for manufacturing three-dimensional textured artificial stone. Background Art

[0002] The existing process of preparing three-dimensional textured artificial stone using permeable materials (such as permeable glaze, permeable ink, etc.) usually sprays the permeable materials with patterns on a flat substrate, so that these permeable materials penetrate into the substrate and form three-dimensional textures inside the substrate. However, this existing process has some fatal disadvantages: first, since the permeation process of the permeable material is accompanied by lateral penetration, the three-dimensional texture becomes very blurred and a fine three-dimensional texture pattern cannot be obtained; second, if only a single material (or a single color material) is sprayed without the help of precise spraying equipment such as screen printing and inkjet printing, the surface texture cannot be obtained, that is, expensive screen printing or printing equipment and materials must be used to obtain the surface texture, thereby greatly increasing the production cost.

[0003] Therefore, it is very necessary to improve the existing method to produce artificial stone with strong three-dimensionality, clear texture and deep texture throughout. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a method for manufacturing a three-dimensional textured artificial stone.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A method for manufacturing a three-dimensional textured artificial stone comprises the following steps:

[0010] b. Using a mold with a concave-convex surface to press the substrate so that the upper surface of the substrate is concave-convex;

[0011] S3, performing a subtractive treatment on the substrate processed in step S2, so that the upper surface of the substrate after the subtractive treatment is parallel to the lower surface of the substrate, thereby obtaining the three-dimensional texture artificial stone.

[0012] Preferably, step S2 further includes the following step c or step d:

[0013] c. applying at least one penetrating ink to the upper surface of the substrate, and allowing the applied penetrating ink to penetrate into the interior of the substrate;

[0014] d. Apply the filling material to the upper surface of the substrate to form a filling layer.

[0015] Further preferably, in step c, the penetration depth of at least one penetrating ink in the substrate is 0.05 to 30 mm.

[0016] Preferably, during the infiltration process of step c, the bottom of the substrate is at 0 to 10 -5 Pa environment.

[0017] Preferably, during the infiltration process of step a, the bottom of the substrate is at 0 to 10 -5 Pa environment.

[0018] Preferably, in step a, the penetration depth of the penetrating ink in the substrate is 0.05 to 30 mm.

[0019] Preferably, step S4 includes: drying and curing the substrate before or after the material reduction treatment.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

The present invention applies penetrating ink on the upper surface of the substrate and presses the substrate through a mold to obtain a substrate with a curved permeable layer. Since the permeation concentration of the penetrating ink in the substrate decreases with the penetration depth gradient, the color of the upper surface of the artificial stone after the subtractive treatment varies, so that a new plane texture pattern and a new three-dimensional texture throughout the body are formed on the surface and inside of the substrate.

[0029] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with specific embodiments.

[0033] a. applying the penetrating ink to the upper surface of the substrate, and allowing the applied penetrating ink to penetrate into the interior of the substrate;

[0035] S3, performing a subtractive treatment on the substrate processed in step S2, so that the upper surface of the substrate after the subtractive treatment is parallel to the lower surface of the substrate, thereby obtaining the three-dimensional texture artificial stone.

[0036] The present invention applies penetrating ink on the upper surface of the substrate and presses the substrate through a mold to obtain a substrate with a curved penetrating layer. Since the penetration concentration of the penetrating ink in the substrate decreases gradually with the penetration depth, the color of the upper surface of the artificial stone after subtractive processing varies, so that new plane texture patterns and new three-dimensional full-body textures are formed on the surface and inside of the substrate, so that the finished artificial stone presents a clear and three-dimensional texture pattern.

[0037] In one embodiment, step S2 further includes at least one of the following steps c and d:

[0043] (II) mixing at least two penetrating inks and applying the mixed inks to the surface of a substrate, and allowing the applied penetrating inks to penetrate into the interior of the substrate;

[0044] (III) At least two kinds of penetrating inks are sequentially applied to the surface of a substrate and sequentially penetrate into the interior of the substrate.

[0045] Specifically, in step (I), the penetration depth of the penetrating ink in the matrix is ​​0.05 to 30 mm; for example, the penetration depth of the penetrating ink in the matrix can be 0.05 mm, 0.1 mm, 0.5 mm, 1 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm or a range consisting of any two groups of values ​​therein.

[0046] Specifically, in step (II) and step (III), the penetration depth of each penetrating ink in the matrix is ​​independently 0.05 to 30 mm; for example, the penetration depth of each penetrating ink in the matrix can be independently 0.05 mm, 0.1 mm, 0.5 mm, 1 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm or a range consisting of any two groups of values ​​therein.

[0047] The present invention has no particular restrictions on the color of the penetrating ink in step a and the color of the penetrating ink in step c, and they can be selected according to the requirements of the target texture pattern.

[0049] In one embodiment, during the infiltration process of step a, the bottom of the substrate is at 0 to 10 -5 Pa environment.

[0050] In one embodiment, in step a, the penetration depth of the penetrating ink in the substrate is 0.05-30 mm. For example, in step a, the penetration depth of the penetrating ink in the substrate can be 0.05 mm, 0.1 mm, 0.5 mm, 1 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, or a range consisting of any two groups of values.

[0051] In one embodiment, in step b, the pressing pressure is 0.05-20 kg / cm 2 By controlling the pressing pressure within this range, the matrix can be deformed to form a stable concave-convex surface while avoiding cracks inside the matrix.

[0052] In one embodiment, step S4 includes: drying and curing the substrate before or after the subtractive treatment.

[0053] In one embodiment, the upper surface of the three-dimensional textured artificial stone is a plane.

[0054] In one embodiment, the subtractive processing method includes any one of cutting, scraping and polishing.

[0055] In one embodiment, the penetrating ink is applied by spraying or printing.
