Problems solved by technology

In the existing composite materials, calcium carbonate is mainly used to increase the wear resistance of the material, but calcium carbonate is not conducive to the reduction of friction between the static ring and the moving ring, resulting in increased rotational power of the moving ring and energy consumption; in addition, The existing static ring will also increase the water absorption of the material through nylon fibers, but the overall fiber strength is low

Abstract

The invention discloses a sealed static ring material which comprises phenolic resin, reinforced fibers and a filler; the reinforced fibers comprise nylon fibers and glass fibers and are formed by twisting the nylon fibers and the glass fibers; the filler comprises plaster whiskers, polytetrafluoroethylene and aluminum oxide; the mass ratio of the phenolic resin to the filler is 1:2-1:3. The sealed static ring material disclosed by the invention has the benefits that the advantages are complemented with one another through twisting the nylon fibers and the glass fibers; as the filler comprises the plaster whiskers, the polytetrafluoroethylene and the aluminum oxide, the seal wear resistance and the strength of the whole product are enhanced by matching of the plaster whiskers and the polytetrafluoroethylene.

Description

technical field [0001] The invention relates to a sealing stationary ring material. Background technique [0002] The static ring material of ship stern shaft seal is a kind of composite material, which is mainly used for ship stern shaft seal. Since the material needs to be used in water for a long time, it has high requirements for water absorption and water expansion rate, and the material is subjected to friction for a long time, so it needs to have good wear resistance and strength. In the existing composite materials, calcium carbonate is mainly used to increase the wear resistance of the material, but calcium carbonate is not conducive to the reduction of friction between the static ring and the moving ring, resulting in increased rotational power of the moving ring and energy consumption; in addition, The existing static ring will also increase the water absorption of the material through nylon fibers, but the overall fiber strength is low.
