Description

technical field [0001] The invention relates to the field of rubber seals, in particular to a high-toughness anti-corrosion rubber seal and a preparation method thereof. Background technique [0002] Rubber sealing products are important basic components of all kinds of machinery. Almost all industrial sectors cannot do without them. The quality of the sealing components is directly related to the service life and operation reliability of the machine. Bring loss and trouble, serious can cause vicious accident. Most of the rubber seals are in a corrosive environment, and the toughness of the rubber is required to be very high. [0003] The anti-corrosion performance and toughness of the rubber seals in the prior art cannot meet the needs of actual use, so it is urgent to design a high-toughness anti-corrosion rubber seal to solve the problems in the prior art. Contents of the invention [0004] In order to solve the technical problems in the background technology, the pre...
