Embodiment 1

[0026] The sealing material of the stern shaft includes phenolic resin 1 , filler 2 and reinforcing fiber 3 .

[0027] The preparation steps are as follows:

[0028] 1) Mixing: Add 400g of weighed resin into a mixing container, then add 180g of absolute ethanol, stir to make it evenly mixed, then add 340g of calcium carbonate powder, stir to mix evenly, and set aside.

[0029] Preforming: Pass the nylon rope through the resin mixture, and the resin will hang on the nylon rope. After hanging, the nylon rope will be dried in an oven with a temperature of 80°C. After drying, the solvent will volatilize, the viscosity of the phenolic resin will increase, and the resin will Adhere to the fiber, and then wrap the nylon rope after coating on the mold continuously and tightly until the size reaches the expected outer diameter of the winding. During the winding process, the rotational speed and axial linear speed of the mold should be controlled; the rotational speed of the winding mo...

Embodiment ２

[0041] The sealing material of the stern shaft includes phenolic resin 1 , filler 2 and reinforcing fiber 3 .

[0042] The preparation steps are as follows:

[0043] 1) Mixing: Add 500g of weighed phenolic resin into a mixing container, then add 225g of absolute ethanol, stir to make it evenly mixed, then add 425g of calcium carbonate powder, stir to mix evenly, and set aside.

[0044] Preforming: Pass the nylon rope through the resin mixture, and the resin will hang on the nylon rope. After hanging, the nylon rope will be dried in an oven with a temperature of 80°C. After drying, the solvent will volatilize, the viscosity of the phenolic resin will increase, and the resin will Adhere to the fiber, and then wrap the nylon rope after coating on the mold continuously and tightly until the size reaches the expected outer diameter of the winding.

Abstract

The invention belongs to the technical field of materials, and particularly relates to a screw shaft sealed static ring material for a ship and a preparation method of the screw shaft sealed static ring material. The screw shaft sealed static ring material adopts phenolic resin as the body, calcium carbonate powder as the filler and enhancing fiber as the enhancing structure, enhancing fiber is arrayed in a wound mode, phenolic resin and calcium carbonate filler are evenly mixed under the condition of added solvent according to a certain ratio (the weight ratio of 50-150%) for standby application, enhancing fiber passes through a drying oven at a temperature of 40-80 DEG C after being subjected to pulp hanging through resin mixed liquid, then fiber ropes are wound on a mold, and the mold reciprocates at a constant speed and a certain amplitude in the axial direction while rotating. The fiber ropes stop being wound after being wound to a certain thickness, the mold is completely assembled and then put into a hot press, and the product is obtained after mold press forming. The product can have high strength and wear resistance and have a certain water absorption expansion rate through phenolic resin, carbonate powder filler and enhancing fiber.

Description

technical field [0001] The invention belongs to the field of material technology, and in particular relates to a static ring sealing material for a ship stern shaft and a preparation method thereof. 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. The composite material mainly has phenolic resin as the main body, and a fiber reinforced structure is added inside, on the one hand, the strength of the material is increased, and on the other hand, the water absorption expansion rate of the material is increased; at the same time, calcium carbonate filler is added to the resin to increase the wear resistance of the material. ...
