[0002] There are many types of sponges on the market, including foamed cotton, shaped cotton, rubber cotton, memory cotton and SBR sponge, etc. SBR sponge is widely used in life, such as being made into pillow cores and other products. SBR sponge itself has good wear resistance, but in order to further improve the wear resistance of SBR sponge, improve the technical level in the industry, and break the existing technical barriers, this application proposes a new type of SBR sponge that is different from the existing technology. Utility Model Content

[0003] The utility model aims to further improve the wear resistance of SBR sponge and proposes a high wear-resistant SBR sponge pad.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A highly wear-resistant SBR sponge pad comprises an SBR sponge layer, a soft sponge layer is arranged on the SBR sponge layer, a hard sponge layer is fixedly connected to the bottom end of the SBR sponge layer, a plurality of negative pressure holes are arranged at the bottom of the hard sponge layer, the negative pressure holes are hemispherical structures, and suction cups are fixedly connected in the negative pressure holes.

[0006] Furthermore, the hard sponge layer is a cold foamed sponge layer with a hardness between 55 and 110 degrees.

[0007] Furthermore, the bottom of the hard sponge layer is provided with anti-slip grooves.

[0008] Furthermore, the soft sponge layer is a polyester sponge with a hardness between 10 and 30 degrees.

[0009] Furthermore, the hardness of the SBR sponge layer is between 40 and 90 degrees.

[0010] Furthermore, the soft sponge layer, the SBR sponge layer and the hard sponge layer are all provided with a plurality of air holes.

[0011] The beneficial effects of the utility model are:

[0012] 1. Through the setting of hard sponge layer and soft sponge layer, the two largest contact surfaces of the sponge and the outside world have good wear resistance. Combined with the wear resistance of the SBR sponge layer itself, the wear resistance of this product is further improved.

[0013] 2. Through the setting of SBR sponge layer, soft sponge layer and hard sponge layer, the hardness of multiple parts of the sponge is different, which can better cope with various situations and has strong comfort.

[0014] 3. The sponge pad is fixed by adsorption of the suction cup and the contact surface to prevent the sponge pad from sliding, thereby improving the usability of the sponge pad. The air holes make the sponge pad have good air permeability and improve the comfort of the sponge pad. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A highly wear-resistant SBR sponge pad comprises an SBR sponge layer 2, a soft sponge layer 1 is bonded on the SBR sponge layer, the soft sponge layer 1 is a polyester sponge with a hardness between 10 and 30 degrees, and is suitable for children's toys and seat cushions;

[0021] The bottom of the SBR sponge layer 2 is bonded with a hard sponge layer 3, which is a cold foam sponge layer with a hardness between 55 and 110 degrees. It has a certain hardness and elasticity, can provide a certain degree of collision protection, and can also prevent a certain degree of puncture, and has a certain protective ability;

[0022] The soft sponge layer 1 and the hard sponge layer 3 are both wear-resistant, so that the two largest contact surfaces of the sponge and the outside world have good wear resistance. Combined with the wear resistance of the SBR sponge layer 2 itself, the wear resistance of this product is further improved.

[0023] The SBR sponge layer 2 makes the sponge pad have good shock absorption effect and flexibility, and its hardness is between 40-90 degrees, which is soft, thick and comfortable.

[0024] A plurality of negative pressure holes 5 are provided at the bottom of the hard sponge layer 3. The negative pressure holes 5 are hemispherical structures. Suction cups 6 are bonded inside the negative pressure holes 5. The bottom surfaces of the suction cups 6 and the bottom surfaces of the negative pressure holes 5 are in the same horizontal plane. The sponge pad is fixed by the adsorption of the suction cups 6 and the contact surface, thereby preventing the sponge pad from sliding.

[0025] The bottom of the hard sponge layer 3 is provided with anti-skid patterns 4, which increase the friction between the sponge pad and the contact surface, thereby improving the anti-skid performance of the sponge pad. The soft sponge layer 1, the SBR sponge layer 2 and the hard sponge layer 3 are all provided with multiple air holes 7, which make the sponge pad have good air permeability.

[0026] The working principle of this embodiment: through the soft sponge layer 1 and the hard sponge layer 3, the two largest contact surfaces of the sponge and the outside world have good wear resistance. In combination with the wear resistance of the SBR sponge layer 2 itself, the wear resistance of this product is further improved. The sponge pad is fixed by the adsorption of the suction cup 6 and the contact surface to prevent the sponge pad from sliding. Then, the friction between the sponge pad and the contact surface is increased by the anti-slip pattern 4, thereby improving the anti-slip performance of the sponge pad. Then, the air permeability 7 is used to make the sponge pad have good air permeability.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
