Abstract

The invention discloses a compound seal coating and an application thereof in preparation of a compound seal material. The compound seal coating comprises an adhesive coating on the lowest layer, and in turn comprises a foamed rubber coating, a rubber coating and a resin coating from bottom to top. The adhesive coating is solidified by a rubber metal adhesive; the main components of the foamed rubber coating and the rubber coating are fluororubber and carbon black; and the main components of the outermost resin coating comprise a fluorocarbon resin and polytetrafluoroethylene. The application of the compound seal coating in preparation of the compound seal material is that successively coating each layer, curing and forming. The compound seal coating is high in compression rebound resilience, good in abrasive resistance, temperature resistance and fluid corrosion resistance, is not restrained by the roughness and surface pressure of the seal face, is hard to be damaged, good in durability and can be repeatedly used, and an excellent sealing performance in the fluid environment at the temperature of -30 DEG C to 250 DEG C can be played for a long time, besides, the compound seal coating also has excellent shock absorption, noise reduction, cushion and protection performances.

Description

technical field [0001] The invention belongs to the technical field of chemical materials. The invention relates to a composite sealing coating and its application in preparing a composite sealing material, in particular to a composite sealing coating applied in a high-temperature environment in the industrial field and its application in preparing a composite sealing material. Background technique [0002] Over the years, the phenomenon of "running, leaking, dripping, and leaking" in the industrial field has emerged one after another. Poor sealing performance will not only shorten the service life of mechanical equipment, but also greatly waste energy and cause environmental pollution (waste liquid, waste gas, vibration noise). In recent years, rubber has been used as a coating material to coat metal substrates and is widely used in various fields of the national economy, such as aviation, aerospace, navigation, machinery, electronics, petroleum, chemical industry, metallur...
