Description

Technical Field

[0001] This utility model relates to the field of rubber and plastic gasket technology, and in particular to an EPDM rubber and plastic noise reduction gasket. Background Technology

[0002] EPDM rubber and plastic are widely used in the manufacture of noise reduction gaskets due to their excellent weather resistance, chemical corrosion resistance, elasticity and insulation properties.

[0003] However, in existing technologies, the single function of rubber material in buffering and absorbing vibration is limited in noise reduction in environments with mixed low and high frequencies. Furthermore, in terms of installation and fixation, the simple bonding method used in the past can lead to displacement or detachment when subjected to vibration. Moreover, long-term use can result in environmental corrosion, leading to a decline in material performance. Therefore, an EPDM rubber-plastic noise reduction gasket is needed. Utility Model Content

[0004] The purpose of this invention is to provide an EPDM rubber and plastic noise reduction washer that solves the problems of limited noise reduction effect, easy displacement, and susceptibility to environmental corrosion in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an EPDM rubber and plastic noise reduction gasket, comprising: a rubber and plastic body, mounting and fixing components provided on the upper and lower surfaces of the rubber and plastic body, a noise reduction structural layer provided inside the rubber and plastic body, and a protective coating provided on the upper surface of the rubber and plastic body.

[0006] Preferably, the noise reduction structure layer includes a composite sound insulation layer and a Helmholtz resonant cavity, with the composite sound insulation layer located inside the rubber and plastic body and the Helmholtz resonant cavity evenly distributed above the rubber and plastic body.

[0007] Preferably, the composite sound insulation layer is composed of alternating layers of sound-absorbing cotton and damping material.

[0008] Preferably, the mounting and fixing assembly includes a positioning protrusion, a groove, and fastening bolt holes. The positioning protrusion is located on the upper side of the rubber and plastic body, the groove is located on the other side of the rubber and plastic body, and the fastening bolt holes are evenly distributed on the edge of the rubber and plastic body.

[0009] Preferably, the protective coating is a nano-ceramic coating.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] Through the design of the composite sound insulation layer and Helmholtz resonant cavity, the noise-reducing gasket can effectively treat both high-frequency and low-frequency noise simultaneously, significantly improving the noise reduction effect and providing a quieter operating environment for the equipment. The positioning protrusions and grooves, as well as the fastening bolt holes, ensure the accurate installation and firm fixation of the noise-reducing gasket on the equipment, avoiding the problem of gasket displacement or detachment caused by vibration and displacement during equipment operation, and ensuring the continuous and stable performance of noise reduction. The application of the nano-ceramic protective coating effectively improves the resistance of the rubber and plastic body to external environmental corrosion, reduces the impact of factors such as temperature changes, humidity, and chemical substances on the physical properties of the gasket, thereby extending the service life of the gasket and reducing the maintenance cost of the equipment.

[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] This utility model relates to an EPDM rubber and plastic noise-reducing washer, such as Figure 1-5As shown, it includes a rubber and plastic body 1, which serves as the basic structure of the gasket, providing basic elasticity and cushioning performance. The upper and lower surfaces of the rubber and plastic body 1 are provided with mounting and fixing components 3 for easy installation and docking of the gasket. The interior of the rubber and plastic body 1 is provided with a noise reduction structure layer 2, which plays a role in reducing noise. The upper surface of the rubber and plastic body 1 is also provided with a protective coating 4, which can reduce dust pollution.

[0020] Among them, such as Figure 1-2 As shown, the noise reduction structure layer 2 includes a composite sound insulation layer 201 and a Helmholtz resonant cavity 202. The composite sound insulation layer 201 is disposed inside the rubber and plastic body 1. The composite sound insulation layer 201 is composed of alternating layers of sound-absorbing cotton and damping material. The sound-absorbing cotton can effectively absorb high-frequency noise and convert sound energy into heat energy for dissipation. The damping material is mainly used to suppress low-frequency vibration. By increasing the damping of the vibration system, the transmission of vibration is reduced. The Helmholtz resonant cavity 202 is uniformly disposed above the rubber and plastic body 1. The Helmholtz resonant cavity 202 can resonate with noise of a specific frequency and convert sound energy into mechanical energy, thereby achieving the purpose of noise reduction.

[0021] Among them, such as Figure 1-4 As shown, the mounting and fixing component 3 includes a positioning protrusion 301, a groove 302, and a fastening bolt hole 303. The positioning protrusion 301 is located on the upper side of the rubber and plastic body 1, and the groove 302 is located on the other side of the rubber and plastic body 1. During installation, the positioning protrusion 301 can be embedded into the corresponding groove 302 of the equipment mounting part, and the groove 302 can cooperate with the positioning protrusion 301 on the equipment, thereby achieving accurate positioning and stable installation of the gasket and preventing the gasket from shifting during equipment operation. The fastening bolt holes 303 are evenly distributed on the edge of the rubber and plastic body 1. By using bolts to pass through the fastening bolt holes 303, the gasket is fixed to the equipment, further enhancing the installation stability of the gasket.

[0022] Among them, such as Figure 3 As shown, the protective coating 4 is a nano-ceramic coating, which has excellent wear resistance, high temperature resistance, corrosion resistance, and self-cleaning properties. It can effectively protect the rubber and plastic body 1 from the erosion of external environmental factors, extend the service life of the gasket, and the smooth surface of the nano-ceramic coating can reduce the adhesion of dust and dirt, keep the gasket clean, and help maintain its noise reduction performance.
