Abstract

PROBLEM TO BE SOLVED: To generate a three-dimensional pattern by causing the deformation of a flat sheet by a polymerization rate factor during polymerizing. SOLUTION: The polymerization rate varies on account of a variation factor, so that an original planar pattern and a second stage flat sheet 2 are twisted and deformed. A first stage flat sheet 1 is an acrylic flat sheet of a methylacrylate resin and a usable transparent or monochromatic flat sheet material. The surface of the acrylic flat sheet is a printed surface or an electroplated plastic or a sprayed coating liquid. A polymerizable liquid material M is of the same acrylic resin. Although the first stage flat sheet 1 and the polymerizable liquid material M are of the same material, the pattern is twisted so as to show a three-dimensional effect by the variation factor generated by providing a blocking part.

2. Description of the Related Art The existing flat sheet is generally an acrylic flat sheet or a polyvinyl chloride (PVC) flat sheet synthesized from a methyl acrylate resin. However, both types of flat sheets were usually solid or transparent and had no chromatic effect. In order to provide a better visual effect to the flat sheet, U.S. Pat. No. 4,680,155 discloses a process for producing a flat sheet having a pattern simulating a marble pattern. According to the process of the above patent, at least two different colored liquid polymers are injected into the mold in the form of a contact flow. The lines of the two polymer flows are relatively high and are arranged at an angle. Convection causes the polymer to flow sufficiently and mix to such an extent that it forms a composition simulating the marble pattern (color). However, the flat sheet produced by the process of this patent has only a planar pattern, which cannot provide a visually three-dimensional effect. Therefore, it is an issue for such a flat sheet to increase the market value of a product using the flat sheet. US Patent 468
While the current monochromatic flat sheets made by the process of No. 0155 are useful, they lack versatility and are not three-dimensional.

According to the present invention, a first stage sheet is printed on its surface to form a second stage sheet having a planar pattern. The printed surface of the second stage sheet is reacted with a polymerizable liquid material. After the second stage sheet and the polymerizable liquid material are cured, a recycled flat sheet having a three-dimensional pattern is formed.

Another object of the present invention is to plastically electroplate a second stage sheet to form a second stage flat sheet in which the surface layer of the first stage sheet has a planar pattern, wherein the second stage sheet is electrically plated. It is an object of the present invention to provide a method for producing a recycled flat sheet having a three-dimensional pattern in which the plated surface is allowed to react with the polymerizable fluid material. After the second stage sheet and the polymerizable liquid material are cured, a recycled flat sheet having a three-dimensional pattern is formed.

It is a further object of the present invention that the surface of the first-stage sheet is printed to form a second-stage flat sheet having a planar pattern, the plastic is electroplated, and the second-stage flat sheet is electroplated. It is an object of the present invention to provide a method for producing a recycled flat sheet having a three-dimensional pattern in which the printed, electroplated surface of the staged sheet is allowed to react with the polymerizable fluid material. After the second stage sheet and the polymerizable liquid material are cured, a recycled flat sheet having a three-dimensional pattern is formed.

BRIEF DESCRIPTION OF THE DRAWINGS For a full understanding of these and other objects of the invention as well as the invention itself, and all of which will be apparent to those skilled in the art, the following detailed description of the invention is set forth in the following detailed description. The claims must be understood in conjunction with the figures. Like numbers refer to like or similar parts throughout the specification and drawings.

[0008] Many other advantages and features of the present invention will become apparent to those skilled in the art with reference to the detailed description and drawings, in which preferred structural embodiments containing the principles of the present invention are shown by way of illustration. For ease of understanding the principles of the present invention, reference will now be made to the embodiments illustrated in the drawings. Certain terms are used to describe the same. However, it is not intended that the scope of the invention be limited thereby, and modifications and further improvements of the apparatus shown, further applications of the principles of the invention as set forth herein, will occur to those skilled in the art to which the invention pertains. It can be understood that it can be normally performed.

Referring to FIG. 1, this is a flow chart of the process of the present invention, in which a first stage flat sheet 1 comprises a second stage flat sheet 2 having a blocking portion 21 having a planar pattern and color. A surface print A or plastic electroplate B or a combination of surface print A and plastic electroplate B or paint spray C is formed to form. The first stage flat sheet 1 is an available PVC or acrylic flat sheet product. It is transparent or monochromatic. The second stage flat sheet 2 is placed in a mold, which is filled with a polymerizable liquid material M. Material M is PVC
System or acrylic system. The variables during the polymerization of the material M and the second stage flat sheet are as follows: (1) The material M which can be polymerized with the surface material of the second stage flat sheet 2 which is not isolated by the blocking portion.
The rate of polymerization resulting from the fusion between

(2) The rate of polymerization resulting from the fusion between the body material at the bottom of the blocking portion of the second stage flat sheet and the polymerizable material M. (3) The rate of polymerization between the polymerizable material under the same fusing temperature and the blocking portion of the second stage flat sheet 2 where the block portions have different thermal conductivity for different colors.

Since the rate of polymerization changes due to a variable factor, the original flat pattern and the flat sheet 2 in the second stage are twisted and deformed. After the second stage flat sheet 2 and the polymerizable liquid material M are cooled and cured, a recycled flat sheet 3 having a three-dimensional pattern and a plurality of colors is obtained. The invention will be further described with reference to examples. The first stage flat sheet 1 is an acrylic flat sheet of methyl acrylic resin, which is a transparent or monochromatic flat sheet material available. The surface of the acrylic flat sheet is a printed surface or electroplated plastic or sprayed paint. The polymerizable liquid material M is the same acrylic resin material. The first stage flat sheet 1 and the polymerizable material M are the same material, but the pattern still has a twist to show a three-dimensional effect due to the variation factors caused by the provision of the blocking portions 21. The arrangement of the first stage flat sheet 1 and the polymerizable liquid material M can also be interchanged as follows: acrylic first stage flat sheet vs. PVC liquid material, PVC first stage flat sheet. Liquid material for PVC, first stage flat sheet of PVC versus acrylic liquid material. All of the above arrangements also produce a three-dimensional pattern effect.

Referring to FIG. 2, this shows a portion of a recycled flat sheet made in accordance with the present invention.
A flat sheet with a planar pattern originally exhibits a twisted three-dimensional shape. Referring also to FIG. 3, there is shown a second stage flat sheet 2 provided with blocking portions 21a, 21b having different colors, the blocking portions 21a, 21b being substantially planar (see FIG. 4). ). After filling the mold with the polymerizable liquid material M, the blocking portions 21a, 21b may be twisted or deformed due to variables, and the degree and depth of the twist or deformation may vary as shown in FIGS. The original pattern results.

US Pat. No. 4,680,155 discloses the use of polymerizable liquid materials of different colors, which are mixed at different slopes, heights, and speeds to simulate a marble pattern. However, these patterns are planar in appearance.
