Description
Technical field
The present invention relates to field of rope, specifically a kind of lightweight rigidity self-lubricating composite rope and its preparation side
Method.
Background technique
Every field is covered in the use of wirerope at present --- and suspension bridge, lifting etc. the characteristics of wirerope also clearly remove
Except basic intensity, steel wire rope sling is for comparable hardness, high temperature resistant, resistance to certain corrosion, is conductor.But with chemical fibre class rope
The shortcomings that rope compares, wirerope is that density of material is big, and quality is high, not easy to operate.But chemical fibre cable have it is soft, light, high-strength,
The advantages of easily knotting.Therefore in many application fields, chemical fibre cable gradually substitutes steel wire cable.
Although in some fields, chemical fibre cable completely substitute wirerope, the especially lightweight of high-performance fiber rope,
The main reason for high-strength, corrosion resistance, even more substitution wirerope product.But under lifting, multilaminate coiled operating condition, to rope
Rigidity requirement is high, while requiring lightweight, has high strength-weight ratio, chemical fibre cable is more with the obvious advantage than steel wire cable.But change
Fine class rope due to itself flexibility, laterally it is easily-deformable, cause winch wind, overlapping use when extrusion deformation, rope
The problems such as displacement, is easy initiation accident；Once chemical fibre cable wearability and scratch resistant ability are poor simultaneously, in use by external force
Cutting easily causes fiber fracture of rope and leads to a disaster.Chemical fibre cable will substitute wirerope and still need to solve that rope hardness is low, rope
The problems such as skin-friction force is big, and section is non-round.
Summary of the invention
To solve above-mentioned technical problem, the present invention provides a kind of lightweight rigidity self-lubricating composite rope and its
Preparation method, rope section are circle, and strength-weight ratio is high, can substitute steel wire completely in hoisting and hanging, drilling prospection field
Rope.
The technical solution used to solve the technical problems of the present invention is that:
A kind of lightweight rigidity self-lubricating composite rope, includes wire rope core, wrapping layer and covered plastics layer, the wire rope core is by supra polymer
The multi layer spiral structure with circular cross section that weight polyethylene fiber rope yarn spiral is interwoven, spiral is reversed between layers
Composite finishing coating is arranged in setting, each layer of parallel rope yarn outside, and ingredient accounts for 10- in composite finishing liquid on the wire rope core cross section
30%, wrapping layer is arranged in the wire rope core outside, and covered plastics layer is arranged outside the wrapping layer.
The wrapping layer is set as sheath made of being woven as aromatic polyamide fibre.
The finishing fluid of composite finishing coating in the wire rope core outside every layer of parallel rope yarn mainly by functional urethane or
Polyacrylate aqueous coating glue composition, it further includes in solution weight ratio 1.3%-2% that the weight proportion with water, which is 2:1~4:1,
Thickener, 0.5%-1.5% defoaming agent.
The covered plastics layer is melted by PE through pultrusion, forms the polyethylene clad of 1-3mm thickness in rope surface.
A kind of preparation method of lightweight rigidity self-lubricating composite rope, is achieved by the steps of:
1) rope designs: according to rope specification, designing the thickness of covered plastics layer, calculates rope sectional area, accounts for according to rope yarn area
70-90% calculates rope yarn radical and fineness；
2) preparation rope yarn: several ultra high molecular weight polyethylene fiber multifilament being twisted by ring and are twisted, and the twist is 10~20 twirls/m；
3) spiral interweaves: designing the wire rope core number of plies according to rope diameter, is arranged every layer of yarn spirals using rope machine is turned round, screw pitch foundation
Depending on rope speed and torsion are fast out, twisting is opposite between the adjacent number of plies；
4) coating: using the functional urethane or polyacrylate aqueous coating glue prepared between every layer of yarn of wire rope core
Composite finishing coating is carried out, by die orifice plastic squeeze, carries out the heating, drying of coating solution in the outer layer of wire rope core, binding efficiency is greater than 40%.
5) knitted thermal sheath: by aromatic polyamide yarn interlacement weave at rope sheath, wrapping layer is formed；
6) it makes plastic rope: rope being fed into plastic wrapping machine and carries out plastic, pultrusion, solidification, molding through round die orifice, in rope
Outside forms covered plastics layer.
The lightweight rigidity self-lubricating composite rope that the present invention illustrates ensure that rope by the structure design for wire rope core
Section is circle, and the wire rope core strength efficiency that spiral is interwoven is higher than wire rope core made of braiding；Wire rope core cordage yarn it is compound
The setting of the sheath of top finish and wrapping layer, ensure that the rigidity of rope while reducing the weight of rope, realize same
Every meter of quality of rope is the 1/7 of every meter of quality of wirerope, at low cost, safety and environmental protection under intensity；The design of rope covered plastics layer guarantees
The self-lubricating of rope surface reduces rope surface frictional force, and protection rope supporting part is invaded by other substances, extends rope
Service life, wound on winder neat, do not lead to the problem of extrusion deformation；To sum up, which has light weight, rigidity
Greatly, it the features such as section circle, self-lubricating, thoroughly realizes and realizes its function using fibrecord substitution wirerope, reduce rope
Manipulation strength and industrial energy consumption, be suitble to large-scale promotion application.

5. a kind of preparation method of lightweight rigidity self-lubricating composite rope as described in claim 1, which is characterized in that pass through
Following steps are realized:
Rope design: according to rope specification, designing the thickness of covered plastics layer (3), calculate rope sectional area, accounts for according to rope yarn area
70-90% calculates rope yarn radical and fineness；
Preparation rope yarn: several ultra high molecular weight polyethylene fiber multifilament being twisted by ring and are twisted, and the twist is 10~20 twirls/m；
3) spiral interweaves: designing wire rope core (1) number of plies according to rope diameter, is arranged every layer of yarn spirals using rope machine is turned round, screw pitch
According to rope speed out and depending on turning round speed, twisting is opposite between the adjacent number of plies；
4) coating: using the functional urethane or polyacrylate aqueous coating glue prepared to every layer of yarn of wire rope core (1)
Between carry out composite finishing coating, by die orifice plastic squeeze, carry out the heating, drying of coating solution, binding efficiency in the outer layer of wire rope core (1)
Greater than 40%；
5) it knitted thermal sheath: by aromatic polyamide yarn interlacement weave at rope sheath, is formed wrapping layer (2)；
6) it makes plastic rope: rope being fed into plastic wrapping machine and carries out plastic, pultrusion, solidification, molding through round die orifice, in rope
Outside forms covered plastics layer (3).
