Description

Technical Field

[0001] This utility model relates to the field of rubber sealing technology, and in particular to a high weather-resistant rubber sealing assembly. Background Technology

[0002] In the fields of industrial equipment, pipeline connections, and sealing, rubber sealing components are widely used to prevent fluid or gas leakage and ensure the sealing performance and safety of systems. However, traditional rubber seals are prone to aging, hardening, and cracking when exposed to high temperatures, ultraviolet radiation, chemical corrosion, or harsh environmental conditions for extended periods, leading to decreased sealing performance and shortened service life. Especially in industries such as chemical, petroleum, and automotive, sealing components need to possess excellent weather resistance, chemical corrosion resistance, and the ability to adapt to complex surface shapes; rubber seals made of a single material often struggle to meet these comprehensive requirements.

[0003] Traditional sealing methods typically involve placing rubber gaskets at pipe joints. However, the sealing effect of a single rubber gasket is limited, and leakage is likely to occur with long-term use. Furthermore, it has poor weather resistance, is prone to aging and hardening, and its service life is affected.

[0004] Therefore, a high weather-resistant rubber sealing component is proposed. Utility Model Content

The silicone rubber ring is inserted into the interior of the slot, and the silicone rubber pad is fixedly disposed on one side of the silicone rubber ring. Silicone rubber has good high temperature resistance and aging resistance.

[0011] As a further embodiment of this invention, the protective coating group includes a PTFE coating and a nano-hydrophobic coating. The PTFE coating is applied to the surface of the polyurethane coating, and the nano-hydrophobic coating is applied to the surface of the PTFE coating. The PTFE coating has good chemical corrosion resistance, and the nano-hydrophobic coating can reduce the adhesion of moisture and dirt to the sealing component.
