Seal ring for special fluororubber motor for nuclear power and preparation method of seal ring

Abstract

The invention discloses a seal ring for a special fluororubber motor for nuclear power and a preparation method of the seal ring. The seal ring for the special fluororubber motor for the nuclear power is prepared from the following raw materials in parts by weight: 85 to 90 parts of fluororubber, 5 to 8 parts of acid-acceptor, 2 to 5 parts of compound vulcanizing agent, 8 to 10 parts of reinforcing agent and 1 to 2 parts of additive. The fluororubber motor seal ring is high in mechanical strength, excellent in oil resistance under high temperature, and suitable for a motor of a nuclear-powered ship.

Description

technical field

[0001] The invention relates to the technical field of sealing rings for motors, in particular to a special fluorine rubber motor sealing ring for nuclear power and a preparation method thereof. Background technique

[0002] The special fluorine rubber motor sealing ring for nuclear power is equipped on the new nuclear power ship motor in China at the request of customers. The motor requires a comprehensive seal against dust, water, grease, and nuclear radiation under ultra-static and dynamic conditions. Therefore, high requirements are put forward for the special fluorine rubber motor sealing ring for nuclear power. In addition to dust resistance, water resistance, grease resistance and nuclear radiation resistance, it also needs to have good weather resistance and high and low temperature resistance. The quality stability of the sealing ring in storage and use is directly related to the safety of the ship in motion. For harsh sea conditions, the quality o...
