Description

Technical Field

[0001] The utility model relates to the technical field of textile carpets, in particular to an anti-slip carpet with a porous film. Background Art

[0002] With the improvement of family living environment and quality of life, more and more families are choosing to lay anti-skid carpets on indoor and outdoor floors such as outside doors, living rooms, bedrooms, bathrooms, etc. TPE materials are increasingly used in the backing of anti-skid carpets because of their certain anti-skid properties, softness, excellent elasticity and toughness, and light weight, environmental protection, long service life, and large processing variability.

[0003] However, most of the TPE-backed anti-skid carpets on the market are fully coated with TPE. Since TPE material is a high molecular polymer with a very dense structure, fully coated TPE anti-skid carpets have the problems of poor air permeability, difficulty in drying, and inability to drain water when laid on wet and slippery surfaces, resulting in non-slip problems.

[0004] The existing Chinese patent with publication number CN205493449U discloses a combined anti-slip carpet, including a surface layer located at the upper part and a base layer located at the lower part, the surface layer and the base layer are detachably bonded together by a connecting piece, the connecting piece is located between the surface layer and the base layer and is distributed at the edges around the surface layer and the base layer, the connecting piece is composed of a buckle group that can be connected to and disassembled from each other, the upper surface and the lower surface of the base layer are respectively provided with anti-slip belts, the anti-slip belts are composed of a plurality of convex anti-slip strips arranged and distributed, and the extension direction of the anti-slip strips located on the upper surface of the base layer is staggered with the extension direction of the anti-slip strips located on the lower surface of the base layer.

[0005] The existing Chinese patent with publication number CN113907588A discloses a carpet anti-skid pad with strip-shaped anti-skid strips and a method for using the same. The carpet anti-skid pad with strip-shaped anti-skid strips comprises a non-woven fabric layer and an anti-skid strip, the lower side of the non-woven fabric layer is fixed with an anti-skid strip, the length of the anti-skid strip is the same as the length of the carpet anti-skid pad, and the upper surface of the non-woven fabric layer is used to place the carpet. The present invention relates to a carpet anti-skid pad with strip-shaped anti-skid strips and a method for using the same.

[0006] The above-mentioned prior art provides a carpet anti-skid pad with strip-shaped or Z-shaped anti-skid strips. By adopting strip-shaped or Z-shaped anti-skid strips as the backing, the problems of poor air permeability, difficulty in drying, and non-anti-skid when encountering water are solved to a certain extent. However, due to the structure of the strip-shaped or Z-shaped anti-skid strips themselves, the strip-shaped or Z-shaped anti-skid strips may warp or break after washing, and for a softer carpet surface layer, the overall unevenness may cause the carpet surface to sag, resulting in an inharmonious pattern on the carpet surface.

[0039] Carpet surface layer 1 Middle layer 2 Porous film layer 3 Porous gap 4 DETAILED DESCRIPTION

[0040] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0041] like Figure 1 and Figure 2 As shown, a non-slip carpet with a porous membrane provided by the utility model includes a carpet surface layer 1, an intermediate layer 2 and a porous membrane layer 3 arranged in sequence from top to bottom, the porous membrane layer 3 is integrally formed, and a plurality of hollow porous gaps 4 are distributed on the porous membrane layer 3, any porous gap 4 extends from the bottom surface of the porous membrane layer 3 to the junction of the intermediate layer 2 and the porous membrane layer 3, or, any porous gap 4 extends from the bottom surface of the porous membrane layer 3 to the intermediate layer 2.

[0042] The utility model provides an anti-skid carpet with a porous TPE film. By setting the bottom-back porous film layer 3 as a hollow porous space 4, the obtained anti-skid carpet with a porous film has excellent air permeability and is easy to spin-dry compared with the fully coated bottom-back TPE carpet on the market. The hollow porous spaces are distributed on the porous film layer to form a suction cup effect, which is conducive to a closer contact between the carpet and the ground, and the anti-skid performance is better. When the carpet is laid on a wet and slippery ground, water can be discharged in time, and the carpet has good anti-skid properties when encountering water. In addition, compared with strip-shaped or Z-shaped anti-skid strips, since the porous film layer 3 adopts an integrated molding structure, the porous film layer 3 is not easy to warp or break after washing, and the carpet surface is smoother, and even for a softer carpet surface layer 1, it will not affect the presentation of the carpet surface pattern.

[0043] Specifically, the material of the porous membrane layer 3 is TPE, and the Shore hardness of the TPE particles is 20-85A. Figure 3 As shown, the thickness of the porous film layer 3 is 0.1-5 mm, and the weight of the porous film layer 3 is 50-1000 g / m 2 .like Figures 4 to 10As shown, the shape of the hole-like gap 4 can be a circle, an ellipse, a triangle, a rectangle, a rhombus, a cross, a plum blossom or other irregular hollow shapes, and the area of ​​a single hole-like gap 4 is 0.25-10000mm 2 The distance between any two pore-shaped gaps 4 is 1.5 mm to 500 mm. The carpet surface layer 1 is a tufted carpet surface layer 1, a knitted carpet surface layer 1, a woven carpet surface layer 1, a needle-punched carpet surface layer 1, a flocked carpet surface layer 1 or a hand-woven carpet surface layer 1. The carpet surface layer 1 can be made of chemical fiber, natural fiber or blended fiber, and the weight of the carpet surface layer 1 is 120-2000 g / m 2 The middle layer 2 is a non-woven fabric, a woven fabric or a knitted fabric, and the middle layer 2 can be made of chemical fibers, natural fibers or blended fibers.

[0044] The anti-slip carpet of the utility model can be firstly compounded with the carpet surface layer 1 and the middle layer 2, and then further compounded with the porous film layer 3, or firstly compounded with the porous film layer 3 and the middle layer 2, and then further compounded with the carpet surface layer 1, or firstly fully coated with TPE film on the middle layer 2, and then punched with hot puncture roller to form porous gaps 4, and finally compounded with the carpet surface layer 1. A feasible implementation method is that for the carpet surface layer 1 with a relatively flat back side, the middle layer 2 can be omitted, and the carpet surface layer 1 can be directly compounded with the porous film layer 3.

[0045] A feasible method for preparing the porous membrane layer 3 is: use a cast machine or a laminating machine to heat the TPE particles to a molten state, and the molten TPE is poured through a die head onto a roller with corresponding holes. At the same time, centrifugal paper is wound onto the roller from the bottom of the roller, and then under the action of a scraper at the rear, the centrifugal paper is adhered to the roller, and then under the extrusion of a pressure roller at the rear, the centrifugal paper and the TPE film are pressed together to form a porous TPE film with porous gaps 4, that is, a porous TPE film layer.

[0046] Another feasible method for preparing the porous TPE film layer is: use a cast iron machine or a laminating machine to heat the TPE particles to a molten state, the molten TPE passes through the cast iron head to form a uniform film, the TPE film is quickly cooled by a cooling roller to fix the shape and structure of the film, and after the film is cooled, a mechanical punching device is used to punch holes in the TPE film according to the shape and spacing of the predetermined porous gaps 4, and then a clean centrifugal paper roll is prepared, and the punched TPE film is physically compounded with the centrifugal paper roll. The compounded TPE film and the centrifugal paper are rolled into a coil by a winding mechanism to obtain a porous TPE film with porous gaps 4, that is, a porous TPE film layer.

[0047] In summary, since the back TPE of the strip-shaped TPE-backed anti-slip carpet on the market is a relatively independent strip structure, the back TPE of the utility model is an integrated porous structure. After multiple uses and washings, the porous film layer 3 of the anti-slip carpet with a porous film of the utility model is not easy to warp or break, and the safety and usage experience are better.
