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
The invention belongs to field of material technology, be specifically related to a kind of screw shaft of ship stationary ring sealing material and preparation method thereof.
Background technology
Boats and ships stern shaft seal static ring material is a kind of matrix material, is mainly used in screw shaft of ship sealing.Because this material require uses for a long time in water, water-intake rate, expansion rate of water absorption are had higher requirements, and this material is subject to friction effect, needs that there is good wear resisting property and intensity.It is main body that this matrix material mainly contains resol, and inner increase fiber reinforcing texture, increases the intensity of material on the one hand, increase the expansion rate of water absorption of material on the other hand; Increase pearl filler in resin simultaneously, increase the wear resistance of material.Domestic at present do not have manufacturer can produce this product.
Summary of the invention
The object of the present invention is to provide and a kind ofly can have certain intensity, well wear resistance, can be immersed in for a long time in water again and larger volume change does not occur, and stern shaft seal static ring material playing sealing function and preparation method thereof.
A kind of boats and ships stern shaft seal static ring material that the present invention proposes, its bulk composition is resol, filler and fortifying fibre is added in resol, described filler is pearl filler, pearl filler Homogeneous phase mixing is in resol, the mass ratio of resol and pearl filler is (50-150): 100, and resol sticks on fortifying fibre, hot-forming after Wrapping formed.
In the present invention, described fortifying fibre is formed by three strands of nylon fiber twisteds, and per share nylon fiber is formed by multiply monfil twisted, and single strand of monofilament fiber wire diameter is at 0.1-0.5mm.
The boats and ships that the present invention the proposes preparation method of stern shaft seal static ring material, concrete steps are as follows:
(1) batch mixing: by resol with pearl filler according to (50-150): the mass ratio of 1 mixes, and obtains resin compound, for subsequent use, and mixing process need increase alcohols as solvent;
(2) premolding: fortifying fibre is passed through resin compound, resin compound is made to stick on fortifying fibre, fortifying fibre after sticking is carried out drying by 50-80 DEG C of baking oven, after dry, solvent can volatilize, resol viscosity can increase, stick on fortifying fibre, then by the fortifying fibre continuous winding after hanging on mould, until size reaches desired size; Rotating speed and the axial line speed of mould will be controlled in winding process; The rotating speed v of Wound Dies

2for mould shaft is to linear velocity;
(3) thermocompression forming: the mould wound is inserted in overcoat sleeve, puts into thermocompressor and carries out hot-forming, cooling:
(4) demoulding: product is taken out from mould.
In the present invention, in step (3), thermocompression forming divides three phases pressurization to heat up:
First stage: the temperature promoting thermocompressor pressing plate, when being warmed up to 60-80 DEG C, is incubated 0.5-1.5h at this temperature, and pressurize, dwell pressure position 5-10MPa, every 5min in pressure maintaining period, pressure release venting is once;
Subordinate phase: promote the temperature of thermocompressor pressing plate to 100-120 DEG C, insulation 0.5-1.5h, dwell pressure 10-20MPa, every 5min in pressure maintaining period, pressure release venting is once;
Phase III: promote the temperature of thermocompressor pressing plate to 120-140 DEG C, insulation 0.5-1.5h, dwell pressure 20-30MPa, every 5min in pressure maintaining period, pressure release venting once.
The stern shaft seal static ring material that the present invention proposes is applied in marine equipment material.
Stern shaft seal static ring material mainly seals, because these parts need long period of soaking in water, so the water-intake rate of these parts needs to be well controlled, the sealing function dependence material of these parts expands at water absorption course and reaches sealing effectiveness, this material in use can rub for a long time simultaneously, need that there is good wear resistance, there is after phenolic resin curing good intensity, resol is good tackiness agent, there is good consistency, multiple material can well be bonded together, increase the wear resistance that calcium carbonate can increase material, increase the water-intake rate that nylon rope can increase material.
Stern shaft seal static ring material provided by the invention is a kind of material for marine equipment.The performance index of this material are: saturated water suction percentage 1%-10%, dry state frictional coefficient≤0.4, hygrometric state frictional coefficient≤0.3, expansion rate of water absorption≤3%, tensile strength >=30MPa.
This product enables product have higher intensity and wear resistance by resol, pearl filler and fortifying fibre, and has certain expansion rate of water absorption.
