Description

Technical Field

[0001] The utility model relates to the technical field of foam, in particular to a wear-resistant and highly elastic foam. Background Art

[0002] Foam is a material made by foaming plastic particles, referred to as foam. Foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, CR, EVA, cross-linked PE, SBR, EPDM, etc. Foam has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, easy to use, flexible bending, ultra-thin volume, and reliable performance. However, the structure of traditional foam is simple, and its shock absorption performance can only rely on the physical properties of its own structure to achieve shock absorption effect. When encountering severe impact, its shock absorption effect is limited and cannot guarantee the safety of the protected items. It is easy to collapse and cannot rebound, causing the foam to deform, thereby reducing the protective effect. Utility Model Content

[0006] As a preferred technical solution, the high-elasticity support frame includes a support seat and a connecting portion, the support seat is close to the wear-resistant layer, and two support seats are fixed at both ends of the connecting portion.

[0007] As a preferred technical solution, the connecting portion is provided with bumps, and the bumps are arranged in order on both sides of the connecting portion.

[0008] As a preferred technical solution, air-avoiding holes are further provided in the foam layer, and the air-avoiding holes are provided between two adjacent high-elasticity support frames.

[0009] As a preferred technical solution, an elastic member is provided in the air avoidance hole, and the elastic member abuts against the bottom and the top of the air avoidance hole.

[0010] As a preferred technical solution, it further includes anti-static foam strips, which are arranged in an orderly manner on the upper end of the wear-resistant layer.

[0011] As a preferred technical solution, the anti-static foam strips are semi-cylinders, and every two adjacent anti-static foam strips abut against each other.

[0012] The beneficial effects of the present invention are: the above-mentioned wear-resistant and highly elastic foam and the anti-static foam strips are semi-cylinders, and every two adjacent anti-static foam strips abut against each other, which reduces static electricity while reducing direct contact of the wear-resistant layer with the outside world, thereby reducing friction with the outside world. The wear-resistant layer is coated on the outer surface of the foam layer, and a highly elastic support frame is provided in the foam layer. When the foam layer is compressed and deformed, the highly elastic support frame also bends and deforms with the pressure. After the pressure disappears, the highly elastic support frame quickly rebounds and resets to support the foam layer to restore its shape, thereby ensuring the protective effect of the foam. The release film is used to protect the adhesive layer. The above-mentioned wear-resistant and highly elastic foam can be adhered to the equipment through the adhesive layer to protect the equipment and prevent the equipment from being severely bumped and damaged.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] [Example 1]

[0018] like Figure 1 and Figure 2As shown, a wear-resistant and highly elastic foam comprises an antistatic foam strip 1, a release film 4, an adhesive layer 3, a foam layer 5 and a wear-resistant layer 2. The adhesive layer 3 is coated on the lower end of the wear-resistant layer 2, and the release film 4 is covered on the outer surface of the adhesive layer 3. The antistatic foam strip 1 is arranged in order on the upper end of the wear-resistant layer 2. The antistatic foam strip 1 is a semi-cylinder, and every two adjacent antistatic foam strips 1 abut against each other, reducing static electricity while reducing direct contact between the wear-resistant layer 2 and the outside world, thereby reducing friction with the outside world. The wear-resistant layer 2 is coated on the outer surface of the foam layer 5, and a high-elastic support frame is provided in the foam layer 5. 6. The highly elastic support frame 6 is equidistantly installed in the foam layer 5, and both ends of the highly elastic support frame 6 are close to the wear-resistant layer 2. The highly elastic support frame 6 is made of a highly elastic metal material. When the foam layer 5 is deformed under pressure, the highly elastic support frame 6 also bends and deforms as it is compressed. After the pressure disappears, the highly elastic support frame 6 quickly rebounds and resets to support the foam layer 5 to restore its shape, thereby ensuring the protective effect of the foam. The release film 4 is used to protect the adhesive layer 3. The above-mentioned wear-resistant and highly elastic foam can be adhered to the equipment through the adhesive layer 3 to protect the equipment and prevent the equipment from being severely bumped and damaged.

[0019] Specifically, the highly elastic support frame 6 includes a support seat 61 and a connecting portion 62. The support seat 61 is close to the wear-resistant layer 2. The two support seats 61 are fixed at both ends of the connecting portion 62, so that the highly elastic support frame 6 can support the entire foam layer 5 to reset. After the connecting portion 62 is compressed and bent, it can quickly rebound, thereby supporting the entire foam layer 5 to reset. The connecting portion 62 is provided with a protrusion 63. The protrusions 63 are arranged in an orderly manner on both sides of the connecting portion 62, which can increase the contact area between the connecting portion 62 and the foam layer 5, so that the foam layer 5 can be closely attached to the connecting portion 62, avoiding the separation of the highly elastic support frame 6 and the foam layer 5, which leads to a weakening of the support rebound effect. The foam layer 5 is also provided with an air avoidance hole 51. The air avoidance hole 51 is arranged between two adjacent highly elastic support frames 6, thereby providing a deformation space for the highly elastic support frame 6 to avoid squeezing the foam layer 5 and causing irreversible deformation.

[0020] [Example 2]

[0021] like Figure 2 and Figure 3As shown, a wear-resistant and highly elastic foam comprises an antistatic foam strip 1, a release film 4, an adhesive layer 3, a foam layer 5 and a wear-resistant layer 2. The adhesive layer 3 is coated on the lower end of the wear-resistant layer 2, and the release film 4 is covered on the outer surface of the adhesive layer 3. The antistatic foam strip 1 is arranged in order on the upper end of the wear-resistant layer 2. The antistatic foam strip 1 is a semi-cylinder, and every two adjacent antistatic foam strips 1 abut against each other, reducing static electricity while reducing direct contact between the wear-resistant layer 2 and the outside world, thereby reducing friction with the outside world. The wear-resistant layer 2 is coated on the outer surface of the foam layer 5, and a high-elastic support frame is provided in the foam layer 5. 6. The highly elastic support frame 6 is equidistantly installed in the foam layer 5, and both ends of the highly elastic support frame 6 are close to the wear-resistant layer 2. The highly elastic support frame 6 is made of a highly elastic metal material. When the foam layer 5 is deformed under pressure, the highly elastic support frame 6 also bends and deforms as it is compressed. After the pressure disappears, the highly elastic support frame 6 quickly rebounds and resets to support the foam layer 5 to restore its shape, thereby ensuring the protective effect of the foam. The release film 4 is used to protect the adhesive layer 3. The above-mentioned wear-resistant and highly elastic foam can be adhered to the equipment through the adhesive layer 3 to protect the equipment and prevent the equipment from being severely bumped and damaged.

[0022] Specifically, the highly elastic support frame 6 includes a support seat 61 and a connecting portion 62. The support seat 61 is close to the wear-resistant layer 2. The two support seats 61 are fixed at both ends of the connecting portion 62, so that the highly elastic support frame 6 can support the entire foam layer 5 to reset. After the connecting portion 62 is compressed and bent, it can quickly rebound, thereby supporting the entire foam layer 5 to reset. The connecting portion 62 is provided with a protrusion 63. The protrusions 63 are arranged in an orderly manner on both sides of the connecting portion 62, which can increase the contact area between the connecting portion 62 and the foam layer 5, so that the foam layer 5 can be closely attached to the connecting portion 62, avoiding the separation of the highly elastic support frame 6 and the foam layer 5, which leads to a weakening of the support rebound effect. The foam layer 5 is also provided with an air avoidance hole 51. The air avoidance hole 51 is arranged between two adjacent highly elastic support frames 6, thereby providing a deformation space for the highly elastic support frame 6 to avoid squeezing the foam layer 5 and causing irreversible deformation. An elastic member 52 is provided in the avoidance hole 51 , and the elastic member 52 abuts against the bottom and top of the avoidance hole 51 , thereby driving the avoidance hole 51 to rebound and reset quickly, preventing the avoidance hole 51 from collapsing and affecting the rebound effect of the high-elasticity support frame 6 .

Therefore, any equivalent changes or modifications made based on the structures, features, and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
