[0002] As a kind of decoration and home furnishing material, floor is widely used in people's life and work. Moreover, with the improvement of people's living standard, people have higher and higher functional requirements for floor, and different needs are generated.

[0016] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0017] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of a floor with surface relief embossing and light-shadow changing provided by the present invention. The floor with surface relief embossing and light-shadow changing includes a base layer 10, a relief layer 20 arranged on the base layer 10, and a wear-resistant layer 30 arranged on the base layer 10. It can be imagined that the floor with surface relief embossing and light-shadow changing also includes other functional components, such as a snap-on structure, a waterproof layer, etc., which are well known to those skilled in the art and will not be described in detail here.

[0018] The base layer 10 is an SPC or PP board. The SPC board is a new type of floor, also known as stone plastic floor. Its base material is a composite board made of stone powder and thermoplastic polymer material that are evenly mixed and then extruded at high temperature. It has the properties and characteristics of both wood and plastic, has a certain degree of flexibility, and ensures the strength and toughness of the floor.

[0019] The relief layer 20 has a plurality of relief areas 21 arranged in an array, and a plurality of boundary lines 22 between adjacent relief areas 21 .

[0020] The relief area 21 is a polygonal structure, which is a hexagon in this embodiment. The edge of the relief area 21 is a circle of raised texture, which is clearly distinguished from the boundary line 22. A plurality of linear textures 211 are arranged at intervals in the relief area 21. The two ends of the linear texture 21 are connected to the edge of the relief area 21, and the distances between adjacent linear textures 21 are equal. Preferably, the distances between adjacent linear textures 21 are equal to the width of the linear texture 21. The linear texture 211 is a raised texture, and the area between two linear textures 211 is a sunken texture. The area occupied by the linear texture 211 and the area between the two linear textures 211 are preferably half each, so as to ensure that the raised texture and the sunken texture in one relief area 21 are evenly distributed, so that the colors in each relief area 21 are consistent. The depth of the linear texture 211 is between 0.05mm and 0.5mm, which can present a good light and shadow gradient. The width of the linear texture 211 is determined according to the size of the relief area 21. Preferably, the width of each linear texture 211 is equal to one fortieth of the width of the relief area 21. The relief area 21 can also be shaped as a triangle, a square, and a rectangle to form a unit module, as long as the linear textures 211 in the adjacent relief areas 21 of each relief area 21 are avoided to be parallel. Preferably, the linear textures 211 in different directions, the angles of the relief area 21 and the linear textures 211 in at least three directions around are between 20 degrees and 30 degrees, ensuring that the difference in COF friction coefficient is within 10%, preferably within 5%, ensuring that the COF friction coefficient is greater than 0.30, and more preferably greater than 0.35.

[0021] In order to achieve the effect of light and shadow transformation, the directions of the linear textures 211 in adjacent embossed areas 21 are different. When the direction of light irradiation is parallel to the direction of the linear texture 211, the light is refracted less, making the color look lighter. When the direction of light irradiation is perpendicular to or at an angle to the direction of the linear texture 211, the larger the angle, the more light is refracted, making the color look darker, thereby making the multiple embossed areas 21 look different in color depth, achieving the effect of light and shadow transformation. At the same time, the use of textures in different tilt directions can have certain anti-slip and anti-fingerprint effects. Through a specific arrangement order and a light source in a fixed direction, the floor can present a light and shadow gradient effect such as in the indoor situation. The demarcation line 22 is a sinking texture, and the smaller the width of the demarcation line 22, the better. Preferably, the width of the demarcation line 22 is 1 to 2 times the width of the linear texture 211, so that the boundaries of the multiple embossed areas 21 are more obvious. The embossed layer 20 is formed by pressing the embossed texture on the embossing roller on the PVC color film.

[0022] The wear-resistant layer 30 is a transparent PVC plate with good chemical stability, corrosion resistance, anti-aging and other characteristics, and is used to protect the relief layer 20. During production, the wear-resistant layer 30 and the relief layer 20 are pressed in advance by hot pressing, and will be pressed by an embossing roller during the pressing process. The embossing roller is provided with a relief texture corresponding to the relief area 21, so as to press out the texture of the relief area 21. The pressed wear-resistant layer 30 and the relief layer 20 are connected to the base layer 10 by glue. The relief layer 20 can also be embossed by applying pressure and heat on the finished board through special calendering or steel plate, and by digital printing combined with 3D-uv printing to achieve embossed relief.

[0023] Compared with the prior art, the floor with surface relief embossing and light-shadow transformation of the present invention is provided with a plurality of relief areas 21 and a plurality of linear textures 211 arranged at intervals are provided in the relief areas 21. The two ends of the linear textures 21 are connected to the edges of the relief areas 21, and the distances between adjacent linear textures 21 are equal. The directions of the linear textures 211 in adjacent relief areas 21 are different. When the direction of light irradiation is parallel to the direction of the linear textures 211, the light is refracted less, making the color look lighter. When the direction of light irradiation is perpendicular to or at an angle to the direction of the linear textures 211, the greater the angle, the more light is refracted, making the color look darker. As a result, the plurality of relief areas 21 appear to have different shades of color, achieving the effect of light-shadow transformation.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
