Abstract
Description
Technical Field
[0001] This utility model belongs to the field of conductive rubber technology, specifically relating to a high-strength heat-resistant conductive rubber. Background Technology
[0002] Conductive rubber is a special type of rubber material in which conductive particles are uniformly distributed in a rubber matrix such as silicone rubber. Pressure is applied to bring the conductive particles into contact, thereby achieving good conductivity. It not only has conductivity but is also often used in applications such as sealing and electromagnetic shielding.
[0003] In the engine compartment of a car, conductive rubber is used to connect components such as sensors and wires. Due to the high temperature inside the engine compartment, especially during long-term driving or in hot weather, the conductive rubber is affected by the high temperature. The high temperature environment causes the rubber matrix to soften, thereby reducing the tensile strength and tear strength of the conductive rubber. This can cause the conductive rubber to deform and crack when subjected to external forces. The cracking of the conductive rubber can lead to short circuits or open circuits in the wires, thereby causing fires or malfunctions. In view of this, a high-strength heat-resistant conductive rubber was designed. Utility Model Content

[0028] This application is described below with reference to the accompanying drawings and specific embodiments:
[0029] Please see Figure 1-4 A high-strength, heat-resistant, and conductive rubber includes a rubber matrix 100, in which conductive particles 200 are uniformly distributed. When the conductive rubber is subjected to pressure, the conductive particles 200 will come into contact with each other to form a conductive path, thereby realizing the transmission of current.
[0030] The top and bottom of the interior of the rubber matrix 100 are respectively provided with a first reinforcing layer 300 and a second reinforcing layer 400;
[0031] Both the first reinforcing layer 300 and the second reinforcing layer 400 include a first reinforcing filament 301 and a second reinforcing filament 302. The first reinforcing filament 301 and the second reinforcing filament 302 are disposed within the rubber matrix 100, which can improve the tensile strength and tear strength of the rubber, prevent the rubber from cracking or deforming when subjected to external forces, and the first reinforcing filament 301 and the second reinforcing filament 302 can also provide additional support and stability, withstand greater mechanical stress, and thus extend the service life.
[0032] The conductive particles 200 are one of the following: silver-plated glass particles, silver-plated aluminum particles, or silver particles.
[0033] The conductive particles 200 are silver-plated glass particles. The surface of the silver-plated glass particles is coated with a layer of pure silver, which has excellent conductivity, thereby ensuring the stable and reliable conductivity of the conductive rubber.
[0034] The conductive particles 200 are aluminum-plated silver particles, which not only have electrical conductivity but also good electromagnetic shielding properties.
[0035] The conductive particles 200 are silver particles. Silver particles not only have excellent electrical conductivity but also high thermal conductivity, which enables the conductive rubber to dissipate heat more effectively in high-temperature environments and maintain stable performance.
[0036] The first reinforcing filament 301 and the second reinforcing filament 302 are arranged in a cross configuration within the rubber matrix 100. This cross configuration forms a more robust network structure, which can more effectively disperse and withstand external forces, thereby improving the overall structural strength of the rubber matrix 100. When the rubber matrix 100 is subjected to tearing force, the cross configuration of the first reinforcing filament 301 and the second reinforcing filament 302 can support and restrain each other, preventing the tear from widening and improving the tear resistance of the rubber. Furthermore, it helps to slow down the softening rate of the rubber matrix 100 at high temperatures, thus improving the heat resistance of the conductive rubber.
[0037] The first reinforcing filament 301 and the second reinforcing filament 302 have the same structure. The first reinforcing filament 301 is one of wear-resistant fiber filament, metal wire or thermally conductive fiber filament.
[0038] The first reinforcing filament 301 is a wear-resistant fiber filament. The wear-resistant fiber filament not only improves the wear resistance of the rubber matrix 100, but also enhances its structural stability. The wear-resistant fiber filament can be firmly embedded in the rubber matrix 100 and form a good bond with the rubber matrix 100, thereby improving the overall strength and stability of the conductive rubber.
[0039] The first reinforcing filament 301 is a metal wire. The metal wire has good electrical conductivity, which can improve the conductivity of the conductive rubber. The metal wire also has electromagnetic shielding properties, which can prevent electromagnetic wave interference and leakage. The metal wire can still maintain a certain strength and stability in high temperature environment, which can improve the heat resistance of the conductive rubber.
[0040] The first reinforcing filament 301 is a thermally conductive fiber filament. Thermally conductive fiber filaments have good thermal conductivity and can effectively transfer heat. In applications that require heat dissipation, thermally conductive fiber filaments, as reinforcing filaments, can improve the heat dissipation efficiency of rubber and prevent overheating and damage.
[0041] The rubber matrix 100 has a heat dissipation structure 500 in the middle, which can increase the heat exchange area between the conductive rubber and the surrounding environment, thereby improving its heat dissipation efficiency and preventing it from being damaged due to overheating.
[0042] The heat dissipation structure 500 includes multiple heat dissipation channels, which are arranged along the length of the rubber substrate 100, so that heat can be transferred rapidly along the length of the rubber substrate 100, thereby improving the heat dissipation efficiency of the rubber substrate 100.
[0043] The upper surface of the rubber matrix 100 is provided with a first insulating layer 600. The upper surface of the rubber matrix 100 is provided with a second insulating layer 700. The first insulating layer 600 and the second insulating layer 700 include, but are not limited to, polyfluoroolefins, polyethylene terephthalate, polyimide, polyamide-imide, heat-shrinkable materials, polyvinyl chloride, or polyolefins. The first insulating layer 600 and the second insulating layer 700 enhance the insulating properties of the rubber matrix 100, providing insulating protection for the circuit.
[0044] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
