Problems solved by technology

However, at present, the taekwondo mats used in taekwondo competitions or training are basically made of EVA plastic particles and pigments (color masterbatch), and there is no anti-skid layer on the surface. Increase its anti-slip degree, resulting in poor anti-slip function of the taekwondo mat, which greatly increases the chance of injury to athletes
Disadvantages of EVA material products: 1. Flammable
Once burned, it will irritate the eyes and skin of the on-site personnel and has a strong irritating smell. If the protection is not good, it will cause great harm to the human body. 2. The product has a high density and poor comfort

Embodiment 1

[0031] Such as figure 1 , 3 -7 shown.

[0032] A kind of composite taekwondo mat with XPE as a sandwich, comprising an anti-slip surface 1, an intermediate layer 2 and an anti-slip bottom surface 3 arranged sequentially from top to bottom; the anti-slip surface 1 is a PVC anti-slip composite layer with anti-slip patterns; the The anti-slip bottom surface 3 is a PVC anti-slip composite layer with anti-slip patterns, the middle layer 2 includes five layers of XPE layers 4, and the densities of the adjacent XPE layers 4 are different.

[0033] The anti-slip resistance range of the anti-slip surface and the anti-slip bottom surface: 30.5N-50.5N; the range of friction coefficient: 0.3-0.55.

[0034] The thickness range of the taekwondo pad: 15-30mm.

[0035] The thickness of the PVC anti-slip composite layer on the anti-slip surface is 1-1.5 mm.

[0036] The five XPE layers of the middle layer 2 are prepared through the existing heat sealing process.

Embodiment 2

[0038] Composite Taekwondo mat as described in Example 1, comprising a square mat 5, a triangular special-shaped mat 6 and a corner mat 7; Splicing primary and secondary teeth 8; the edge of the triangular special-shaped pad 6 is provided with secondary and secondary teeth 9 for splicing; the primary and secondary teeth 8 of the square pad are compatible with the primary and secondary teeth 9 of the triangular special-shaped pad; the edge The corner pad 7 is a rectangle, which is the edge part of the taekwondo pad after the whole combination: when the corner pad is the edge of the taekwondo pad, the three sides of the rectangular corner pad have teeth 12; when the corner pad is When the taekwondo corner pad is on the edge, two adjacent sides of the rectangular corner pad have teeth 13 .

Embodiment 3

[0040] Composite taekwondo mat as described in Example 2, the difference is that one end of the largest hypotenuse of the triangular special-shaped mat 6 is provided with a convex tooth 11, the convex tooth is 20mm high and 95-160mm in length.

Abstract

The invention discloses a composite material taekwondo pad with a sandwich made from XPE. The composite material taekwondo pad comprises a non-slip surface, an intermediate layer and a non-slip bottom surface, which are sequentially arranged from top to bottom, wherein the non-slip surface is made of a PVC non-slip composite layer with non-slip patterns; the non-slip bottom surface is made of a PVC non-slip composite layer with non-slip patterns or an embossing XPE layer with convex-concave patterns; the intermediate layer is formed by multiple XPE layers; and the density of the adjacent XPE layers is the same or different. According to the invention, the intermediate layer is prepared by compounding the multiple XPE layers with the same or different density through a heat seal process, so that the made pad has the advantages of high comfort level, moderate hardness and high impact resistance. According to the non-slip patterns on the non-slip surface and the non-slip bottom surface, the friction force of the whole pad is increased, and the comfort level of a user is guaranteed on the basis that the friction is increased. A taekwondo site is laid by the composite material taekwondo pads, the composite material taekwondo pad is high in overall flatness, high in safety, good in service effect and high in durability and is suitable for wide popularization and application, and the stability and safety of athletes in the sports process are effectively guaranteed.

Description

technical field [0001] The invention relates to a composite material taekwondo mat with XPE as a sandwich core, belonging to the technical field of sports equipment. Background technique [0002] With the continuous development of sports, the difficulty of taekwondo is becoming more and more difficult, and the risk factor is also higher and higher for athletes. Therefore, the requirements for taekwondo mats are also getting higher and higher, not only need to have enough buffer It also needs to protect the personal safety of athletes and protect athletes from injury to the greatest extent. However, at present, the taekwondo mats used in taekwondo competitions or training are basically made of EVA plastic particles and pigments (color masterbatch) foamed, and the surface layer has no anti-skid layer, which is achieved by directly making patterns on the surface. Increase its anti-slip degree, resulting in poor anti-slip function of the taekwondo mat made, greatly increasing t...
