The invention discloses a reinforced silicone rubber sealing ring. The reinforced silicone rubber sealing ring is characterized in that a silicone rubber sealing ring body (1) is included, and the upper surface of the silicone rubber sealing ring body (1) is compounded with a first polytetrafluoroethylene layer (2); the lower surface of the silicone rubber sealing ring body (1) is compounded with a second polytetrafluoroethylene layer (3), the thickness ratio of the silicone rubber sealing ring body (1) to the first polytetrafluoroethylene layer (2) is 4:1, and the thickness ratio of the first polytetrafluoroethylene layer (2) to the second polytetrafluoroethylene layer (3) is 2:1. According to the reinforced silicone rubber sealing ring, polytetrafluoroethylene is compounded to the surfaces of silicone rubber, so that the manufactured reinforced silicone rubber sealing ring is good in tensile strength and tearing strength mechanical performance and high in heavy solvent resisting capacity, can meet the needs of most mechanical equipment and is low in cost.
Description
technical field [0001] The invention relates to the field of mechanical accessories, in particular to a reinforced silicone rubber sealing ring. Background technique [0002] In the field of mechanical equipment, silicone rubber has excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric aging resistance. The outstanding performance of silicone rubber is that it can be used at -90 ° C (or lower) Temperature) to +300°C (or higher temperature) for long-term use. However, the tensile strength and tear strength mechanical properties of silicone rubber are poor, and its physical and mechanical properties are inferior to most synthetic rubbers at room temperature, and its oil resistance and solvent resistance are poor, so the scope of use of silicone rubber is subject to many restrictions. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a reinforced silicone rubber sealing rin...
