[0002] VCM laminated boards are widely used in the fields of home appliance housings and building wall panels. It is difficult to achieve a three-dimensional cloth-texture effect on VCM laminated boards. The current conventional production method is to draw or emboss one side of the PET film, which has no three-dimensional texture and has a poor cloth-texture effect. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a method for manufacturing a three-dimensional cloth-textured laminated board, which can manufacture a laminated board with rich three-dimensional texture and deep cloth-textured effect.

[0022] Reference Figure 1 The present invention discloses a method for manufacturing a three-dimensional cloth-textured laminate, comprising the following steps:

[0023] A vertical drawing pattern 71 is formed on the back of the first transparent film 7 by physical drawing, a polyester coating is applied on the vertical drawing pattern 71 to form a first polyester coating 6, and then an aluminum plating process is performed on the first polyester coating 6 to form a translucent aluminum plating layer 5, and a polyester coating is applied on the aluminum plating layer 5 to form a second polyester coating 4;

[0024] UV curing glue is coated on the front side of the second transparent film 9, and is pressed by a pressure roller with transverse lines, and cured by UV lamp to form a UV embossed layer 10 with transverse wire drawing lines;

[0025] The composite glue is applied on the back of the second transparent film 9, and then laminated with the front of the first transparent film 7 by dry lamination and cured;

[0026] The composite glue is coated on the front side of the base film 3, and then laminated with the second polyester coating 4 on the first transparent film 7 by a dry lamination method and cured;

[0027] Glue is applied on the back side of the base film 3 and attached to the front side of the substrate 1 to obtain a finished product.

[0028] Among them, according to different needs, the base film 3 can be selected from different colors of film materials, and the base film 3 constitutes the background color of the film-coated board. The aluminum coating 5 is translucent, and different light transmission effects can be obtained by adjusting the thickness of the aluminum coating 5. The first polyester coating 6 and the second polyester coating 4 can improve the bonding performance and isolate air and water vapor to prevent chemical reactions with the aluminum coating 5.

[0029] Reference Figure 1 In this method, a first transparent film 7 and a second transparent film 9 are superimposed on the base film 3, wherein a vertical brushed pattern 71 is formed on the back of the first transparent film 7, wherein the horizontal brushed pattern and the vertical brushed pattern 71 are superimposed on different planes to form a three-dimensional cloth texture effect, and the base film 3 constitutes the background color of the finished laminated board, achieving a deep sense of brushed texture and rich three-dimensional texture.

[0030] In some embodiments of the present invention, the method further comprises the following steps: before applying the composite glue on the back of the second transparent film 9, a translucent colored ink is first applied to form a colored ink layer 8, so that the finished laminated board has different color effects.
