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 preparation method for a sealing static ring material. The preparation method comprises the following steps: preparing packing from gypsum whiskers, polytetrafluoroethylene and aluminum oxide; preparing a fiber carrier by twisting nylon fibers and glass fibers; and enabling the fiber carrier to sequentially pass through phenolic resin and packing, thereby realizing step-by-step fusion of phenolic resin and packing. The static ring material prepared by the preparation method is small in friction force, is resistant to friction, is high in strength and is resistant to corrosion.

Description

technical field [0001] The invention relates to a preparation method of 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. ...
