[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a high thermal stability plastic flooring, including a board body 1. The board body 1 includes a bottom layer 101, a base layer 102 above the bottom layer 101, a stabilizing layer 103 above the base layer 102, a heat insulation layer 104 above the stabilizing layer 103, and a wear-resistant layer 105 above the heat insulation layer 104. Multiple transverse grooves 8 are formed through the left and right sides of the board body 1, arranged in two layers. Multiple longitudinal grooves 6 are formed through the front and rear sides of the board body 1, located between the two layers of transverse grooves 8. A transverse connecting assembly for fixing adjacent plates 1 is provided between two adjacent plates 1 on the left and right sides, and a longitudinal connecting assembly for fixing adjacent plates 1 on the front and back sides is provided between two adjacent plates 1 on the back and front sides. The bottom layer 101 is made of rubber, the base layer 102 is made of polyvinyl chloride as the main raw material, which is blended and granulated by a twin-screw extruder and then hot-pressed. The stabilizing layer 103 is made of glass fiber mesh to improve bending strength and sound insulation performance. The thermal insulation layer 104 is made of calcium carbonate. Calcium carbonate board has high compressive strength and a thermal conductivity of 0.045~0.062W / (m·K). This structure effectively insulates against heat. The wear-resistant layer 105 is a UV coating that forms a dense polymer film on the surface, significantly improving the wear resistance and scratch resistance of the substrate. During production, the base layer 102 is first extruded from the extruder. Then, adhesive is applied to the bottom and top of the base layer 102. The bottom layer 101 is then bonded to the bottom of the base layer 102, and the heat insulation layer 104 is bonded to the top of the base layer 102. Before bonding the heat insulation layer 104, the stabilizing layer 103 is placed between the heat insulation layer 104 and the base layer 102. After the adhesive dries, UV paint is sprayed, and the wear-resistant layer 105 is then coated. 5. UV lamp irradiation curing is performed to form a wear-resistant layer 105, thereby making the plastic flooring preform. The heat insulation layer 104 can isolate the air above, so that the temperature is not easily transferred to the base layer 102 below. Even in high temperature environment, the ambient temperature of the base layer 102 remains low. Temperature radiation will also cause a slight increase in the temperature of part of the base layer 102, causing the base layer 102 to expand. The longitudinal grooves 6 and transverse grooves 8 will accommodate the expansion, so that the base layer 102 as a whole will not be squeezed and deformed, thus improving the service life of the plastic flooring.

[0022] In this invention, the transverse connecting assembly includes a first connecting frame 2 disposed between two adjacent left and right panels 1. Multiple second inserts 9 are integrally formed on both sides of the first connecting frame 2, and the second inserts 9 can be inserted into transverse grooves 8. When installing two plastic floorboards left and right, firstly, the second inserts 9 on the first connecting frame 2 are inserted into the transverse grooves 8 of the plastic floorboards via interference fit. Then, another plastic floorboard is placed on the other side of the first connecting frame 2, and the second inserts 9 on the other side of the first connecting frame 2 are inserted into the transverse grooves 8 via interference fit, thereby completing the assembly of the two adjacent left and right plastic floorboards. The longitudinal connecting assembly includes components disposed between two adjacent front and rear panels 1. The second connecting frame 3 has multiple first inserts 7 integrally formed on both sides, and the first inserts 7 can be inserted into the longitudinal groove 6. When installing two plastic floorboards one after the other, firstly, the first inserts 7 on the second connecting frame 3 are inserted into the longitudinal groove 6 of the plastic floorboard. Then, the other plastic floorboard is placed on the other side of the second connecting frame 3, and the first inserts 7 on the other side of the second connecting frame 3 are inserted into the longitudinal groove 6, thereby completing the assembly of the two adjacent plastic floorboards. This allows for quick installation and positioning, improving the installation efficiency of the plastic floorboards. Both the first connecting frame 2 and the second connecting frame 3 are made of stainless steel with poor thermal conductivity.

[0023] The top of the board 1 has a groove 4, and a protrusion 5 is integrally formed in the groove 4. During the installation of the first connecting frame 2 and the second connecting frame 3, the protruding parts of the top of the first connecting frame 2 and the second connecting frame 3 will be inserted into the groove 4 and held in place by the protrusion 5. At the same time, after the installation is completed, the top of the first connecting frame 2 and the second connecting frame 3 are at the same level as the top of the board 1, which prevents the protrusion from causing people to trip during walking. The board 1 has buffer grooves 10 on all four sides, and the buffer grooves 10 on all four sides are connected to prevent the plastic floor from expanding and squeezing the first connecting frame 2 and the second connecting frame 3, so that there is a gap between the first connecting frame 2, the second connecting frame 3 and the plastic floor, which improves the comfort of using the floor.

[0024] The working principle of this utility model is as follows: During production, the base layer 102 is first extruded from the extruder. Then, adhesive is applied to the bottom and top of the base layer 102. The bottom layer 101 is then attached to the bottom of the base layer 102, and the insulation layer 104 is attached to the top of the base layer 102. Before the insulation layer 104 is attached, the stabilizing layer 103 is placed between the insulation layer 104 and the base layer 102. After the adhesive dries, UV paint is sprayed, and the wear-resistant layer 105 is cured by UV light to form the wear-resistant layer 105, thereby making the plastic flooring preform. The insulation layer 104 can isolate the air above, making it difficult for the temperature to be transferred to the base layer 102 below. Even in high-temperature environments, the ambient temperature of the base layer 102 remains relatively low. Temperature radiation will also cause a slight increase in the temperature of some parts of the base layer 102, causing the base layer 102 to expand. The longitudinal grooves 6 and transverse grooves 8 will accommodate the expansion, preventing the base layer 102 from being squeezed and deformed, thus improving the service life of the plastic flooring.
