Description

Technical Field

[0001] This utility model relates to the field of insulating shell technology, specifically to a nitrile rubber insulating shell with high temperature resistance. Background Technology

[0002] Nitrile rubber (NBR) is a special rubber material with excellent oil resistance, abrasion resistance, and aging resistance. It is mainly composed of butadiene and acrylonitrile copolymers; by adjusting the ratio of the two, NBR products with different properties can be prepared. This rubber is widely used in the automotive industry, petrochemical industry, medical devices, and other fields, and its excellent sealing and oil resistance make it an indispensable material in many industries.

[0003] However, in existing technologies, nitrile rubber insulating shells exhibit certain limitations in high-temperature environments. Although they possess good oil resistance and abrasion resistance, their long-term operating temperature is typically limited to 100℃, and they can only be used intermittently or for short periods in environments above 120℃. This limitation is mainly due to the cyano groups in the molecular chain structure being prone to electric field polarization, leading to a decrease in dielectric properties and thus affecting their insulation performance at high temperatures. Therefore, we provide a nitrile rubber insulating shell with high-temperature resistance. Utility Model Content

[0004] The purpose of this invention is to provide a nitrile rubber insulating shell with high temperature resistance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nitrile rubber insulating shell with high-temperature resistance, comprising a nitrile rubber shell, an insulating shell disposed on the outside of the nitrile rubber shell, a shell cover disposed on the top of the insulating shell, two sets of slots being provided on the top of the shell cover, an insulating ceramic coating disposed on all four sides of the insulating shell, a graphene insulating plate disposed between the interior of the insulating shell and the nitrile rubber shell, a filling layer disposed on the inner wall of the insulating shell, glass fiber cotton disposed inside the filling layer, and a sealing mechanism disposed on the top of the shell cover.

[0008] As a further preferred embodiment of this technical solution, the bottom of the sealing gasket is mated in the sealing groove, and the bolt passes through the threaded groove opened in the shell cover and is fixed with the internal thread of the mounting groove.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a high-temperature resistant nitrile rubber insulating shell includes a nitrile rubber shell 11, an insulating shell 12 on the outside of the nitrile rubber shell 11, a shell cover 13 on the top of the insulating shell 12, two sets of slots 14 on the top of the shell cover 13, insulating ceramic coatings 15 on all four sides of the insulating shell 12, and insulating ceramic coatings 15 fixedly connected to all four sides of the insulating shell 12, a graphene insulating plate 16 between the inside of the insulating shell 12 and the nitrile rubber shell 11, a filling layer on the inner wall of the insulating shell 12, glass fiber cotton 18 inside the filling layer, the nitrile rubber shell 11 abutting the inner surface of the graphene insulating plate 16, glass fiber cotton 18 fixedly connected inside the filling layer, and a sealing mechanism 2 on the top of the shell cover 13.

[0022] In this embodiment, when the nitrile rubber insulating shell is required, in order to ensure the high-temperature resistance of the shell, the nitrile rubber shell 11 is installed inside the heat insulation shell 12, and a graphene heat insulation plate 16 is provided between the heat insulation shell 12 and the nitrile rubber shell 11. Graphene has extremely high thermal conductivity, which means that it can quickly conduct heat. However, due to its special two-dimensional structure, the heat transfer between graphene layers is greatly restricted, thus exhibiting excellent heat insulation effect. By filling the inner wall of the heat insulation shell 12 with glass fiber cotton 18, the heat insulation performance of the entire system can be significantly improved, reducing heat loss and external heat transfer, thereby maintaining the temperature stability inside the equipment or system. In addition, the sound absorption performance of glass fiber cotton 18 can effectively reduce the noise generated during equipment operation, improving the comfort and quietness of the working environment. Heat insulation ceramic coating 15 is added to all four sides of the outside of the heat insulation shell 12. The heat insulation ceramic coating 15 has low thermal conductivity and can effectively block heat transfer. This efficient heat insulation performance helps to maintain the temperature stability inside the equipment or system and reduce heat loss.

[0023] like Figures 1-4As shown, the sealing mechanism 2 includes four bolts 21, which are respectively set in the threaded grooves opened at the four corners of the top of the cover 13. A sealing gasket 22 is fixedly connected to the bottom of the cover 13. A sealing groove 24 is opened at the top of the heat insulation shell 12. An installation groove 23 is opened at each of the four corners of the top of the heat insulation shell 12. The bottom of the sealing gasket 22 is mated in the sealing groove 24. The bolts 21 pass through the threaded grooves opened in the cover 13 and are fixed with the threads inside the installation grooves 23.

[0024] In this embodiment, the cover 13 can be securely installed on the heat insulation shell 12 by means of the provided bolt 21 and mounting groove 23, and the sealing gasket 22 will be mated in the mounting groove 23, so that the gap between the cover 13 and the heat insulation shell 12 can be sealed.

[0025] This utility model provides a nitrile rubber insulating shell with high temperature resistance, and its specific working principle is as follows:

[0026] When using nitrile rubber insulation shells, to ensure their excellent high-temperature resistance, we adopted an effective installation method. Specifically, we installed the nitrile rubber shell 11 inside the heat insulation shell 12, and placed a graphene heat insulation plate 16 between the heat insulation shell 12 and the nitrile rubber shell 11. Graphene, as a material with extremely high thermal conductivity, can rapidly conduct heat. This characteristic significantly improves the thermal insulation performance of the entire system after filling the inner wall of the heat insulation shell 12 with glass fiber cotton 18. This design effectively reduces heat loss and the ingress of external heat, thus helping to maintain the temperature stability inside the equipment or system. In addition, we added a heat-insulating ceramic coating 15 to the four outer sides of the heat insulation shell 12. This coating has low thermal conductivity and can effectively block heat transfer. In this way, not only is the thermal insulation effect further enhanced, but it also helps to maintain the temperature stability inside the equipment or system, further reducing heat loss.

[0027] 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.
