Description

Technical Field

[0001] The present application relates to a method for manufacturing an ultra-thin stone skin and the ultra-thin stone skin. Background Art

[0002] The traditional method of obtaining stone skin is cutting, which can only obtain thinner stones instead of real stone skin, which limits the scope of stone application and makes the cost of stone relatively high. As a material with natural patterns, stone is deeply loved by people. If its thickness can be reduced to a certain level, its application scope will be greatly expanded and the cost will be reduced. Summary of the invention

[0003] In view of this, the technical problem to be solved by the present application is to provide a method for manufacturing an ultra-thin stone skin and an ultra-thin stone skin, so as to solve the problem that the ultra-thin stone skin in the prior art is difficult to obtain and the stone skin is not bendable and therefore cannot be applied to curved surfaces.

[0004] In order to solve the above problems, the present application provides a method for making an ultra-thin stone skin, comprising the following steps:

[0005] A natural sedimentary rock block is prepared, and the sedimentary rock block is polished to form at least one plane; a high-temperature resistant liquid resin layer is brushed on the plane; a non-woven fabric is then covered on the liquid resin layer; the liquid resin layer and the non-woven fabric are then dried to fix the non-woven fabric on the plane; finally, the non-woven fabric is mechanically peeled off from the sedimentary rock block, and when the non-woven fabric is detached from the sedimentary rock block, the outermost layer of the sedimentary rock is peeled off from the sedimentary rock block, and finally a stone skin with a thickness of 0.3 mm to 3.0 mm is formed.

[0006] An ultra-thin stone skin is obtained by the above-mentioned production method.

[0007] The ultra-thin stone skin achieved in the present application has the pattern and feel of natural stone skin and can be bent. It can be used not only for the skinning of flat objects but also for the skinning of bent surfaces; and the non-woven fabric and high-temperature resistant resin provide a good injection molding foundation and good high-temperature resistance for the ultra-thin stone skin, so that the natural composite stone skin has the opportunity to further form decorative materials with complex shapes and structures on the basis of injection molding, such as as automotive interior materials.

[0008] Figure 1 Shown is a schematic diagram of the implementation process of a method for making an ultra-thin stone skin provided in an embodiment of the present application. DETAILED DESCRIPTION

[0009] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0010] The present application provides a method for making an ultra-thin stone skin, comprising the following steps:

[0011] A natural sedimentary rock block is prepared, and the sedimentary rock block is polished to form at least one plane; a high-temperature resistant liquid resin layer is brushed on the plane; a non-woven fabric is then covered on the liquid resin layer; the liquid resin layer and the non-woven fabric are then dried to fix the non-woven fabric on the plane; finally, the non-woven fabric is mechanically peeled off from the sedimentary rock block, and when the non-woven fabric is detached from the sedimentary rock block, the outermost layer of the sedimentary rock is peeled off from the sedimentary rock block, and finally a stone skin with a thickness of 0.3 mm to 3.0 mm is formed.

[0012] In one embodiment, the liquid resin used is a polyurethane adhesive.

[0013] In one embodiment, after covering the non-woven fabric on the liquid resin layer, a layer of resin is brushed on the surface of the non-woven fabric, and then covered with another layer of non-woven fabric.

[0014] In one embodiment, the stone blocks brushed with resin and covered with non-woven fabrics are dried or naturally air-dried to fix the non-woven fabrics on the plane of the deposited rock blocks.

[0015] In one embodiment, the non-woven fabric is peeled off by slowly tearing off the non-woven fabric along the edge of the plane of the sedimentary rock block, and the outermost layer of the natural sedimentary rock block is peeled off the surface of the original sedimentary rock block due to adhesion to the non-woven fabric.

[0016] Another aspect of the present application provides an ultra-thin stone skin, which is obtained by the production method of the above embodiment.

[0017] In one embodiment, the stone skin is used as an automobile interior material and can enter a mold for injection molding and cutting, ultimately achieving automobile interior products of various shapes and even styles, achieving a good hand feel and rich plasticity.

[0018] The implementation process and technical effects of the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, a method for making an ultra-thin stone skin provided by an embodiment includes the following steps:

[0020] S1, preparing a natural sedimentary rock block, and grinding the sedimentary rock block to form at least one plane;

[0021] Preferably, the selected natural sedimentary rock block is cut into a cuboid. It is placed on a platform, and then the upper surface is polished to form a plane. Sedimentary rocks are usually formed in places not too deep on the surface of the earth through the transportation, deposition, and diagenesis of water or glaciers. Therefore, sedimentary rocks are characterized by stratification. The stratification structure is a layered structure displayed by the changes in the composition or particle size of the sediment along the direction perpendicular to the sediment surface and the lateral extension.

[0022] S2, brushing a layer of high temperature resistant liquid resin on the plane;

[0023] The resin layer should fully cover the surface of the stone and form a certain thickness. Specifically, the liquid resin is a polyurethane adhesive.

[0024] S3, covering the liquid resin layer with a non-woven fabric while the liquid resin layer is still in a liquid state;

[0025] A layer of non-woven fabric is immediately covered on the liquid resin layer while it is still in a liquid state, so that the non-woven fabric and the liquid resin layer are fused together.

[0026] S4, then drying the liquid resin layer and the non-woven fabric to fix the non-woven fabric on the plane of the sedimentary rock block;

[0027] Drying can be done by drying in a dryer or by natural air drying.

[0028] S5, then mechanically peeling off the non-woven fabric from the sedimentary rock block, when the non-woven fabric is detached from the sedimentary rock block, the outermost layer of the sedimentary rock is peeled off from the sedimentary rock block, and finally forming a stone skin with a thickness of 0.3mm-3.0mm, for example 0.5mm, 0.8mm, 1mm, 2mm.

[0029] The peeling process is to slowly tear off the non-woven fabric along the edge of the plane. The outermost layer of the natural sedimentary rock block is peeled off from the surface of the original sedimentary rock block due to its adhesion to the non-woven fabric, thereby forming a natural composite stone skin formed by the combination of stone powder with natural patterns and non-woven fabric.

[0030] In order to make the obtained stone skin have a thicker feel, after step S3 and before step S5, the following steps are further performed: brushing resin on the surface of the non-woven fabric again, and then covering it with a layer of non-woven fabric; and then performing S5.

[0031] In one embodiment, the stone skin is used for automobile interior decoration materials, which are suitable for further injection molding to form automobile accessories with complex shapes.

[0032] The preferred embodiments of the present invention are described above with reference to the accompanying drawings, but the scope of the present invention is not limited thereby. A person skilled in the art may implement the present invention in a variety of variations without departing from the scope and essence of the present invention, such as using a feature of one embodiment to obtain another embodiment. Any modification, equivalent substitution and improvement made within the technical concept of the present invention shall be within the scope of the present invention.
