[0009] Furthermore, the upper surface of the sheet body has a plurality of strip grooves extending through both sides.

[0010] Furthermore, the lengths of the first convex strip and the second convex platform are equal to the width of the strip groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The sheet body in the utility model comprises a PU color-changing layer, a PVC hard layer and a bonding layer, which are arranged in sequence from the outside to the inside. The PU color-changing layer is a thin film formed by adding color-changing particles into modified polyurethane through processing. The PU color-changing layer is compounded with the PVC hard layer through a laminating machine, and then the PVC hard layer is glued to form the sheet body. The finished product has soft and dazzling colors and has strong spatial elements and three-dimensional sense. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0017] like Figure 1-2 As shown, this embodiment provides a colorful and color-changing PVC decorative sheet, including a sheet body 1, and the sheet body 1 includes a PU color-changing layer 11, a PVC hard layer 12 and an adhesive layer 13.

[0018] The PU color-changing layer 11, the PVC hard layer 12 and the bonding layer 13 are arranged in sequence from the outside to the inside. The PU color-changing layer 11 is composed of color-changing particles and polyurethane. The thickness of the PU color-changing layer 11 is 50-160 microns, and the thickness of the PVC hard layer 12 is 30-600 microns. The color of the PU color-changing layer 11 changes with the angle of sight, and is visually very gorgeous.

[0019] The sheet body 1 has a first convex strip 14 at the bottom of one side, and a second convex strip 15 at the top of the other side. The thickness of the first convex strip 14 plus the thickness of the second convex strip 15 equals the thickness of the sheet body 1. When installing, the first convex strip 14 and the second convex strip 15 can be spliced, which can be used to determine whether the splicing is crooked. Preferably, the first convex strip 14 has a limiting groove 151, and the second convex strip 15 has a limiting column 141 below. The limiting column 141 corresponds to the limiting groove 151, so that positioning can be performed more quickly during installation.

[0020] The upper surface of the sheet body 1 has a plurality of conical grooves 16 arranged in a matrix, the depth of the conical grooves 16 being lower than the thickness of the PU color-changing layer 11 . The plurality of conical grooves 16 can enhance the three-dimensional effect of the sheet body 1 .

[0021] In another embodiment, the upper surface of the sheet body 1 has a plurality of strip grooves 17 extending through both sides, and the width difference between the first convex strip 14 and the second convex platform is equal to the width of the strip groove 17 , which can enhance the three-dimensional effect of the sheet body 1 .

[0022] The sheet body 1 of this scheme includes a PU color-changing layer 11, a PVC hard layer 12 and an adhesive layer 13, which are arranged in sequence from the outside to the inside. The PU color-changing layer 11 is a thin film formed by adding color-changing particles into modified polyurethane through processing. The PU color-changing layer 11 is compounded with the PVC hard layer 12 by a laminating machine, and then the PVC hard layer 12 is glued to form the sheet body 1. The finished product has soft and dazzling colors and has strong spatial elements and three-dimensional sense.
