[0002] With the improvement of family living environment and life quality, more and more families begin to choose to lay non-slip carpet on indoor and outdoor ground such as door, living room, bedroom and bathroom. Because TPE material has certain non-slip property, softness, excellent elasticity and toughness, and light quality, environmental protection, long service life, large processing change degree etc., it is applied more and more on non-slip carpet back bottom.

[0003] However, most of the TPE back bottom non-slip carpets on the market at present adopt full TPE coating. Because TPE material is a kind of high molecular polymer structure and is very dense, full TPE coating non-slip carpet has the problems of poor air permeability, not easy to dry, water cannot be discharged when laid on wet and slippery ground, leading to non-slip.

[0004] The existing Chinese patent with publication number CN205493449U discloses a combined non-slip carpet, which comprises 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 through connecting pieces. The connecting pieces are located between the surface layer and the base layer and are distributed at the edges of the surface layer and the base layer. The connecting pieces are composed of buckles that can be connected and detached with each other. The upper surface and the lower surface of the base layer are respectively provided with anti-slip strips. The anti-slip strips are composed of a plurality of outward protruding anti-slip strips arranged and distributed. The extension direction of the anti-slip strips on the upper surface of the base layer and the extension direction of the anti-slip strips on the lower surface of the base layer are interlaced with each other.

[0005] The existing Chinese patent with publication number CN113907588A discloses a carpet non-slip pad with strip-shaped anti-slip strips and a using method thereof. The carpet non-slip pad with strip-shaped anti-slip strips comprises a non-woven fabric layer and anti-slip strips. The lower side of the non-woven fabric layer is fixed with anti-slip strips.

[0006] The above-mentioned existing technology discloses a carpet non-slip pad with strip-shaped or Z-shaped anti-slip strips. By adopting strip-shaped or Z-shaped anti-slip strips as the bottom back, the problems of poor air permeability, not easy to dry and not non-slip when encountering water are solved to a certain extent. However, due to the structure of the strip-shaped or Z-shaped anti-slip strips, the strip-shaped or Z-shaped anti-slip strips may be warped or broken after washing. For a relatively soft carpet surface layer, the unevenness of the whole may cause the carpet surface to be depressed, resulting in the problem of inconsistent patterns of the carpet surface.

[0040] Blanket layer 1, Intermediate layer 2, Porous membrane layer 3, Porous pores 4 Detailed Implementation

[0041] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0042] As shown in Figures 1 and 2, the non-slip carpet with a perforated membrane provided by this utility model includes a carpet surface layer 1, an intermediate layer 2, and a perforated membrane layer 3 arranged sequentially from top to bottom. The perforated membrane layer 3 is integrally formed, and a plurality of hollow perforated gaps 4 are distributed on the perforated membrane layer 3. Any perforated gap 4 extends from the bottom surface of the perforated membrane layer 3 to the junction of the intermediate layer 2 and the perforated membrane layer 3, or any perforated gap 4 extends from the bottom surface of the perforated membrane layer 3 to the intermediate layer 2.

[0043] This invention relates to an anti-slip carpet with a porous TPE film. By setting the perforated film layer 3 of the backing to hollowed-out perforated gaps 4, the resulting anti-slip carpet with a porous film has superior breathability and is easier to spin dry compared to commercially available full-coated TPE backing carpets. Furthermore, the perforated gaps on the film layer create a suction cup effect, which facilitates closer contact between the carpet and the ground, resulting in better anti-slip performance. When the carpet is laid on a wet or slippery surface, water can be drained in time, providing good anti-slip performance when wet. In addition, compared to strip or Z-shaped anti-slip strips, the perforated film layer 3 is integrally molded, making it less prone to curling or breaking after washing, and the carpet surface is smoother. Even on softer carpet layers 1, it does not affect the presentation of the carpet pattern.

[0044] Specifically, the porous membrane layer 3 is made of TPE, and the Shore hardness of the TPE particles is 20-85A. As shown in Figure 3, the thickness of the porous membrane layer 3 is 0.1-5mm, and the weight of the porous membrane layer 3 is 50-1000g / m³. 2 As shown in Figures 4 to 10, the shape of the perforated void 4 can be a circular, elliptical, triangular, rectangular, rhomboid, cross-shaped, plum blossom-shaped, or other irregular hollow geometric shapes. The area of ​​a single perforated void 4 is 0.25-10000 mm². 2The distance between any two hole gaps 4 is 1.5mm-500mm. 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-knitted carpet surface layer 1, which is made of chemical fibers, natural fibers or blended fibers, and the weight of the carpet surface layer 1 is 120-2000g / m 2 The intermediate layer 2 is a non-woven fabric, a woven fabric or a knitted fabric, which is made of chemical fibers, natural fibers or blended fibers.

[0045] The anti-skid carpet can be used in the following way: the carpet surface layer 1 and the intermediate layer 2 are compounded first, and then the hole-shaped membrane layer 3 is compounded further; or the hole-shaped membrane layer 3 and the intermediate layer 2 are compounded first, and then the carpet surface layer 1 is compounded further; or the TPE film is fully coated on the intermediate layer 2 first, and then the hole-shaped gaps 4 are formed by using a hot needle roller, and finally the carpet surface layer 1 is compounded. In a feasible implementation, for the carpet surface layer 1 with a relatively flat back, the intermediate layer 2 can be omitted, and the carpet surface layer 1 is directly compounded with the hole-shaped membrane layer 3.

[0046] A feasible preparation method of the hole-shaped membrane layer 3 is as follows: the TPE particles are heated to a molten state by using a casting machine or a film coating machine, the molten TPE is coated on a roller with a corresponding hole shape through a die head, the centrifugal paper is wound on the roller from below the roller, and then the centrifugal paper is adhered to the roller under the action of a rear scraper, and then the centrifugal paper and the TPE film are pressed together under the extrusion action of a rear pressure roller, so as to form a hole-shaped TPE film with hole-shaped gaps 4, i.e. a hole-shaped TPE film layer.

[0047] Another feasible preparation method of the hole-shaped TPE film layer is as follows: the TPE particles are heated to a molten state by using a casting machine or a film coating machine, the molten TPE is formed into a uniform film through a casting head, the TPE film is rapidly cooled through a cooling roller to fix the shape and structure of the film, the film is cooled, and then a mechanical punching device is used to punch the TPE film according to the shape and distance of the hole-shaped gaps 4, a clean centrifugal paper roll is prepared, the punched TPE film is physically compounded with the centrifugal paper roll, and the compounded TPE film and the centrifugal paper are wound into a roll by a winding mechanism, so as to obtain a hole-shaped TPE film with hole-shaped gaps 4, i.e. a hole-shaped TPE film layer.

[0048] In summary, since the back TPE of the strip-shaped TPE back anti-skid carpet on the market is a relatively independent strip structure, the back TPE of the present anti-skid carpet is an integrated hole structure, the hole-shaped membrane layer 3 of the present anti-skid carpet with a hole-shaped membrane is not easy to be warped or broken after multiple uses and washing, and the safety and use experience are better.
