Description

Technical Field

[0001] The utility model relates to a waterproof stone plastic floor, belonging to the field of stone plastic floors. Background Art

[0002] The current stone plastic floor is mainly composed of a stone plastic layer, a decorative layer, a topcoat layer and a support layer made of foam material at the bottom. The plug-in tenons of the current stone plastic floor are directly machined from the end face of the stone plastic layer; the stone plastic floors are fixed by plugging. Due to this mode, the end faces between the decorative layer and the stone plastic layer and between the stone plastic layer and the support layer are exposed at the joint position. The water accumulation on the floor surface can easily seep through the joint to the ground, and at the same time, it is also easy to erode between the decorative layer and the stone plastic layer and between the stone plastic layer and the support layer through the joint position, thereby causing the stone plastic material to be soaked in water. At the same time, the adhesives between the decorative layer and the stone plastic layer and between the stone plastic layer and the support layer are soaked in water and deteriorated, and finally, it is easy to cause mildew or swelling inside the floor, affecting the normal use and service life of the floor. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the technical problems in the prior art and provide a waterproof stone plastic floor.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A waterproof stone plastic floor; including:

[0006] A stone plastic layer, an insertion protrusion is provided at one axial end of the stone plastic layer, and an inlay groove corresponding to the insertion protrusion is provided at the other axial end of the stone plastic layer;

[0007] A support part, the support part includes a convex support piece provided on the upper surface of the insertion protrusion and a concave support piece provided on the upper surface of the inlay groove;

[0008] A decorative layer, the decorative layer covers the surface of the stone plastic layer, and the stone plastic layer and the decorative layer are adhesively fixed through a waterproof adhesive;

[0009] Wherein, the waterproof adhesive extends from the bonding gap between the stone plastic layer and the decorative layer towards both ends, one axial end of the waterproof adhesive covers the upper surface of the convex support piece, and the other axial end of the waterproof adhesive covers the upper surface of the concave support piece.

[0010] As a further improvement of the utility model, a waterproof filling cavity is respectively provided at both axial ends of the stone plastic layer corresponding to the ends of the insertion protrusion and the inlay groove. The ends of the convex support piece and the concave support piece are embedded into the corresponding waterproof filling cavities, and the waterproof filling cavities are filled with a waterproof adhesive integrated with the stone plastic layer and the decorative layer.

[0011] As a further improvement of the present utility model, bending portions are respectively provided at both axial ends of the decorative layer. The bending portions are embedded into the waterproof filling cavity. A bending cavity is provided inside the bending portions, and waterproof glue is integrally filled inside the bending portions.

[0012] As a further improvement of the present utility model, a plurality of strip-shaped filling grooves are provided on the surface of the stone plastic layer corresponding to the inlaid grooves and the inserted protrusions.

[0013] As a further improvement of the present utility model, an embedding protrusion is provided on one side of the inserted protrusion facing the decorative layer, and an extending protrusion for embedding into the tail end of the embedding protrusion is provided at the end of the inlaid groove.

[0014] As a further improvement of the present utility model, a first bending portion is provided at the position of the embedding protrusion on the protruding support piece, and a second bending portion is provided at the position of the extending protrusion on the concave support piece.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. The present utility model improves the original structure of the stone plastic floor. The decorative layer and the stone plastic layer are bonded by waterproof glue. At the same time, the relatively rigid concave support piece and protruding support piece are used to replace the stone plastic layer that is prone to thermal stress deformation for combination. At the same time, waterproof glue is integrally coated on the surfaces of the concave support piece and the protruding support piece, thereby realizing the airtight contact of the waterproof glue between adjacent stone plastic floors. Through the combination of the concave support piece and the protruding support piece, a waterproof layer composed of waterproof glue is formed on the surface of the stone plastic floor, reducing the possibility of water collection and penetration. Moreover, the decorative layer is generally made of pure organic materials and will not be additionally mixed with materials such as silicon powder, so the influence of soaking in water is relatively small.

[0017] 2. A large amount of waterproof glue can be filled in the waterproof filling cavity, effectively reducing the possibility of water seepage passing through the joint between the decorative layer and the waterproof glue and contacting the stone plastic layer; at the same time, the certain elasticity of the waterproof glue ensures the airtight effect of the contact between the decorative layers.

[0018] 3. The bending portion can increase the bonding strength between the decorative layer and the waterproof layer. Because the waterproof glue has relatively lower bonding strength compared with the adhesives in the prior art, good floor stability can be ensured by this method.

[0019] 4. The filling grooves further increase the contact area between the waterproof glue and the stone plastic layer, improving the bonding effect of the waterproof glue.

[0020] 5. The extending protrusion and the embedding protrusion can increase the buckle strength and at the same time increase the waterproof sealing contact area, improving the sealing effect. Description of the Drawings

[0027] A waterproof stone plastic floor; comprising:

[0028] As Figure 1 , for the stone plastic layer 1, an insertion protrusion 7 is provided at one axial end of the stone plastic layer 1, and a mosaic groove 8 corresponding to the insertion protrusion 7 is provided at the other axial end of the stone plastic layer 1. An embedded protrusion 9 is provided on one side of the insertion protrusion 7 facing the decoration layer 3, and an extension protrusion 13 for embedding into the tail end of the embedded protrusion 9 is provided at the end of the mosaic groove 8.

[0029] As Figure 1 , for the support part, the support part includes a protrusion support piece 10 provided on the upper surface of the insertion protrusion 7 and a concave support piece 12 provided on the upper surface of the mosaic groove 8. A first bending part 11 is provided at the position of the embedded protrusion 9 on the protrusion support piece 10, and a second bending part 14 is provided at the position of the extension protrusion 13 on the concave support piece 12.

[0030] As Figure 1 , for the decoration layer 3, the decoration layer 3 covers the surface of the stone plastic layer 1. The stone plastic layer 1 and the decoration layer 3 are adhesively fixed by the waterproof glue 5. A plurality of strip-shaped filling grooves 6 are provided on the surface of the stone plastic layer 1 corresponding to the positions between the mosaic groove 8 and the insertion protrusion 7.

[0031] As Figure 1, wherein, the waterproof glue 5 extends towards both ends from the bonding gap between the stone plastic layer 1 and the decorative layer 3. One axial end of the waterproof glue 5 covers the upper surface of the convex support piece 10, and the other axial end of the waterproof glue 5 covers the upper surface of the concave support piece 12. At both axial ends of the stone plastic layer 1 corresponding to the insertion of the ends of the convex 7 and the ends of the inlaid grooves 8, a waterproof filling cavity 15 is respectively provided. The ends of the convex support piece 10 and the concave support piece 12 are embedded into the corresponding waterproof filling cavities 15, and the waterproof filling cavities 15 are filled with the waterproof glue 5 integrated with the stone plastic layer 1 and the decorative layer 3; at both axial ends of the decorative layer 3, bending parts 16 are respectively provided. The bending parts 16 are embedded into the waterproof filling cavities 15, and bending cavities are arranged in the bending parts 16, and the bending parts are integrally filled with the waterproof glue 5.

[0032] Such as Figure 1 and Figure 2 , when manufacturing this product, first, milling processing is carried out on both ends of the stone plastic board that constitutes the main body of the stone plastic layer 1 to process the inserted convex 7 and the inlaid groove 8, and at the same time, the filling groove 6 and the waterproof filling cavity 15 are processed. Subsequently, hot bending processing is carried out on the decorative layer 3. After that, the waterproof glue 5 is coated on the surface of the stone plastic board, and the concave support piece 12, the convex support piece 10 and the decorative layer 3 are placed. Subsequently, through a vacuum barrel, the floor is vacuum cured, and through milling processing, the excess overflowing waterproof glue 5 is removed. Finally, the decorative layer 3 is polished and a topcoat layer 4 with a protective effect is sprayed, and the support layer 2 is adhered to the bottom of the stone plastic layer 1 to complete the processing.

[0033] Such as Figure 3 , when assembling this product, the concave support piece 12 will contact the waterproof glue 5 layer coated on the surface of the convex support piece 10. At the same time, during construction, a layer of waterproof glue 5 or waterproof wax can also be pre-coated on the waterproof glue 5 on the surface of the convex support piece 10. The convex support piece 10 and the concave support piece 12 are made of brass material with high hardness. On the premise that the stone plastic layer 1 does not undergo serious deformation, it can ensure the tight combination between the convex support piece 10 and the concave support piece 12, ensure the stable contact seal at the bonding position that plays a major waterproof role. At the same time, the waterproof glue 5 in the waterproof filling cavity 15 and the bending part 16 also reduce the possibility of seepage water eroding between the stone plastic layer 1 and the decorative layer 3.
