Problems solved by technology

[0002] The main function of the sealing pad applied to the equipment is to seal between the components on the equipment and reduce the wear and tear of the components on the equipment. When the equipment is in a humid environment, the salt dissolved in water will affect the sealing pad on the equipment. Corrosion, corrosion causes crystallized salts to adhere to the surface of the sealing rubber pad, rough surface of the sealing rubber pad, etc. These conditions will not only affect the sealing between the devices, but also cause wear on the device itself during the vibration of the equipment and corrosion. In addition, the rough surface of the sealing rubber pad leads to poor sealing between devices. Therefore, how to provide a sealing rubber pad with a smooth surface that can not be corroded in a wet environment has attracted more and more attention.

Abstract

The invention provides a seal rubber mat capable of preventing salt corrosion. The seal rubber mat is made from silicone rubber, fluororubber, an anti-aging agent DNP, an anti-aging agent CMA, white carbon black, calcium carbonate, iron oxalate, an accelerator NOBS, an accelerator DPTH, t-butyl perbenzoate, benzoyl peroxide and epoxy resin. The preparation method comprises the steps that (1) the fluororubber is subjected to plastication; (2) after the plastication, the fluororubber is mixed with the silicone rubber and other components in an open mill for mixing; (3) the rubber compound is subjected to remilling; (4) extrusion forming and vulcanization are carried out, and the seal rubber mat is obtained. The seal rubber mat has the advantages of smooth surfaces, strong resistance to corrosion and long service life, simple preparation process, reasonable components and safe production during the preparing process.
