[0001] This utility model relates to the field of fluororubber pad technology, specifically to an anti-aging fluororubber pad. Background Technology

[0002] Fluororubber possesses excellent resistance to hydrocarbons, corrosion, oils, and high temperatures. Particularly noteworthy is its outstanding compression resistance at high temperatures, making it widely used in aerospace, automotive, and petroleum industries. Fluororubber gaskets exhibit excellent high-temperature resistance, allowing for long-term use at 250°C and short-term use at 300°C. They also demonstrate exceptional aging and weather resistance. Furthermore, fluororubber exhibits extremely high stability against organic liquids, acids, alkalis, and oils, surpassing other types of rubber. Special fluororubber products, such as fluororubber gaskets, also show good resistance to hot water and high-temperature steam.

[0003] Despite its many advantages, fluororubber still has room for improvement in certain applications. In particular, fluororubber pads are susceptible to aging and damage due to environmental factors and wear after prolonged use. Utility Model Content

[0008] Preferably, the bottom base pad has an annular groove on the side facing the top base pad, and the depth of the groove is half the thickness of the reinforcing layer.

[0009] In a further preferred embodiment, the reinforcing layer includes an inner ring band, an outer ring band, and multiple intermediate ring bands. The inner and outer ring bands are concentrically distributed on the same plane. The multiple intermediate ring bands are distributed at equal intervals along the inner and radial directions between the inner and outer ring bands, and both ends of each intermediate ring band are fixedly connected to the inner and outer ring bands, respectively. The reinforcing layer also includes several connecting bands, which are concentrically arranged between the inner and outer ring bands, and each connecting band is fixedly connected to the multiple intermediate ring bands.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 and Figure 2 An anti-aging fluororubber pad includes a bottom base pad 10, a top base pad 20, a reinforcing layer 30, and a coating layer. The bottom base pad 10 and the top base pad 20 are symmetrically arranged, with their opposing sides bonded and fixed together. Both the bottom base pad 10 and the top base pad 20 can be made of fluororubber material. An inner cavity is formed between the bottom base pad 10 and the top base pad 20, and the reinforcing layer 30 is disposed within this cavity and bonded to both the bottom base pad 10 and the top base pad 20. The reinforcing layer 30 enhances the overall deformation resistance and breakage resistance of the fluororubber pad. The coating layer is disposed on the outside of the bottom base pad 10 and the top base pad 20, covering their outer surfaces, and enhances the overall anti-aging properties of the fluororubber pad.

[0020] See Figure 3The reinforcing layer 30 may include an inner ring band 31, an outer ring band 32, several connecting bands 33, and multiple intermediate ring bands 34. The inner ring band 31 and the outer ring band 32 are concentrically distributed on the same plane, and the several connecting bands 33 are concentrically arranged between the inner ring band 31 and the outer ring band 32, and the several connecting bands 33 are arranged as rings with proportionally varying diameters. The multiple intermediate ring bands 34 are distributed at equal intervals along the inner ring band 31 and radially between the inner ring band 31 and the outer ring band 32. Each intermediate ring band 34 is fixedly connected to a connecting band 33, and both ends of each intermediate ring band 34 are fixedly connected to the inner ring band 31 and the outer ring band 32, respectively, so that the inner ring band 31, the outer ring band 32, the several connecting bands 33, and the multiple intermediate ring bands 34 form a ring network shape. The inner diameter of the inner ring 31 and the outer diameter of the outer ring 32 are adapted to the inner and outer diameters of the groove 11, respectively, so that the reinforcing layer 30 can be embedded in the cavity formed between the bottom base pad 10 and the top base pad 20. The outer ring 31, outer ring 32, several connecting strips 33, and multiple intermediate ring strips 34 can all be made of materials such as polyester fiber, nylon fiber, or glass fiber. These fiber materials have high strength and modulus, which can enhance the overall strength of the fluororubber pad and improve its tear resistance.

[0021] See Figure 2 The coating layer includes a first outer coating 40, a second outer coating 50, and an inner coating 60. The first outer coating 40 and the second outer coating 50 can be hot-pressed together using polytetrafluoroethylene (PTFE) films and respectively wrapped around the outer sides of the bottom base pad 10 and the top base pad 20. Furthermore, the formed first outer coating 40 and the second outer coating 50 are arranged in a symmetrical structure. The inner coating 60 can be formed into a ring using PTFE film and bonded to the inner side of the bottom base pad 10 and the top base pad 20, and the inner coating 60 can be adhered and fixed to the bottom base pad 10 and the top base pad 20 using adhesive. The molecular chain of PTFE is composed of carbon atoms and fluorine atoms. The extremely high electronegativity of fluorine makes the structure of PTFE very stable and robust, and this stable molecular chain structure provides the material with excellent wear resistance. The helical molecular chain of polytetrafluoroethylene (PTFE) results in very low intermolecular sliding resistance and thus an extremely low coefficient of friction. This characteristic makes PTFE less prone to wear during friction, thereby improving its wear resistance. Furthermore, the coating layer covering the outer surfaces of the bottom substrate 10 and the top substrate 20 reduces the impact of the external environment on them, thereby reducing oxidation and UV radiation and enhancing their anti-aging capabilities.

[0022] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as bonding, welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, bonding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
