[0024] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.
[0025] Example
[0026] See also Figure 1 、 Figure 2, this embodiment provides an environmentally friendly conductive foam, including an anti-collision frame 1, a sponge 2, a conductive cloth 3 and an aluminum foil layer 4. Among them, the outside is protected by the anti-collision frame 1, which increases the anti-collision performance without hindering the conductive performance of the conductive foam, thereby extending the service life of the conductive foam; specifically, the anti-collision frame 1 is composed of a first anti-collision half frame 11, a second anti-collision half frame 12, a first shaping ring 13 and a second shaping ring 14. One end of the first anti-collision half frame 11 is connected to one end of the second anti-collision half frame 12 through the first shaping ring 13. The first shaping ring 13 covers one end of the first anti-collision half frame 11 and one end of the second anti-collision half frame 12 and is fixedly connected by sol. The other end of the first anti-collision half frame 11 is connected to the second anti-collision half frame 12. The other ends of the frames 12 are connected by a second shaping collar 14, which covers the other end of the first anti-collision half frame 11 and the other end of the second anti-collision half frame 12 and is fixedly connected by glue. A deformable sponge accommodating chamber with upper and lower openings is formed between the first anti-collision half frame 11 and the second anti-collision half frame 12, and sponges 2 of different shapes and sizes can be placed in the deformable sponge accommodating chamber, so that sponges of different shapes and sizes can be replaced according to different usage environments; preferably, the first anti-collision half frame 11 and the second anti-collision half frame 12 are rubber components, which can reduce the weight of the environmentally friendly conductive foam; combined with Figure 3 As shown, the first shaping ring 13 and the second shaping ring 14 both include an insulating soft rubber sleeve 131 and a metal shaping sheet 132. The metal shaping sheet 132 is embedded in the insulating soft rubber sleeve 131. The shape adjustment and change are achieved through the metal shaping sheet 132. The insulating soft rubber sleeve 131 is a closed structure that can play a protective role and prevent the metal shaping sheet 132 from contacting the outside. In this way, the first shaping ring 13 and the second shaping ring 14 can adjust and change the deformable sponge accommodating chamber. After the deformable sponge accommodating chamber is placed in the sponge body 2, the first shaping ring 13 and the second shaping ring 14 can also play the role of elastic binding, thereby pressing the sponge body 2. Figure 4As shown, the sponge body 2 includes a heat-insulating layer 21, a flame-retardant sponge layer 22, an inner ring 23 and an active carbon layer 24 from the outside to the inside. The heat-insulating layer 21, the flame-retardant sponge layer 22, the inner ring 23 and the active carbon layer 24 are fixedly connected by gluing; wherein, the heat-insulating layer 21 has a heat-insulating effect; brominated flame retardants are added to the flame-retardant sponge layer 22 to absorb the heat generated during conduction; the active carbon layer 24 can absorb harmful gases generated by the brominated flame retardants to prevent them from spreading and endangering human health. The conductive cloth 3 covers the upper opening of the deformable sponge storage chamber and is connected to the anti-collision frame 1. The conductive cloth 3 is provided separately and is a separate structure from the sponge body 2. When the conductive cloth 3 or the sponge body 2 needs to be replaced, the conductive cloth 3 only needs to be directly removed, which is convenient to use and can greatly save material costs. Specifically, a plurality of screw holes 15 are provided on the frame of the first anti-collision half frame 11 and the second anti-collision half frame 12. The conductive cloth 3 is connected to the first anti-collision half frame 11 and the second anti-collision half frame 12 by fixing screws 5. Preferably, the fixing screws 5 are made of plastic material to reduce the weight of the environmentally friendly conductive foam. The aluminum foil layer 4 covers the lower opening of the deformable sponge storage chamber and is connected to the anti-collision frame 1 through an adhesive layer. When in use, the aluminum foil layer 4 can be directly torn off and the environmentally friendly conductive foam can be fixed to the device to be shielded using the adhesive layer. It is convenient and quick.
[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
