Abstract
A method for preparing cable rope of high strength PP network thread includes improving raw material preparing process of drawing, twisting and folding to add tension balance unit at twisting frame for holding tension and straightness of each thread to ensure force balance on each thread when it is on service so as to increase service strength of cable rope; improving raw material of said rope to add 30% of PE pellets and 2% of UV-531 or 2% of HA88-NEW in PP pellets for making said rope be able to be used under high temperature.
Description
Technical field
The present invention relates to a kind of ropework, particularly a kind of processing method and material prescription thereof that utilizes the polypropylene fibre network yarn to make hawser as raw material.
Background technology
High-strength polypropylene fibre network yarn hawser is a kind of Cable rope for ship of newly developing in the alkene scope in gathering, and its main feature is light specific gravity, corrosion-resistant, wear-resisting wiping, uses softness, light, is present widely used a kind of tackle.But this sharp hawser in use also has tensile strength shortcoming low, that at high temperature should not use when possessing above-mentioned advantage.
The manufacture craft of existing polypropylene fibre network yarn hawser is:
Raw material-wire drawing-twist thread-pool capital-rope making.
At the existing deficiency of product, through sufficient research and analysis, think existing in the hawser of synthetic fibre network yarn made, the main cause that its tensile strength is not high is the stage of twisting thread.Because monofilament merges under free position, cause the monofilament bending, the irregular phenomenon of exerting oneself, treating just to seem after product is made, rope strand is firmly irregular, has reduced the tensile strength of rope virtually.
The raw material of synthetic fibre network yarn hawser is a simple PP particle (polypropylene fibre) in existing, and its deficiency is that the hawser that is made can not be high temperature resistant, can not at high temperature use.
Summary of the invention
Technical barrier to be solved by this invention is, in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of tensile strength height, and the processing method of the high-strength polypropylene fibre network yarn hawser that can at high temperature use.
The technical solution that the present invention taked is, raw material by wire drawing, twist thread, plying, rope making be made, it is characterized in that: in the twisting technique process, in the back of the every group of support of twisting thread the autobalance tensioner is installed, make every monofilament of twisting keep straight tensioning, pool capital then, rope making.
Described raw material is made up of PP particle, PE particle and additive, and its additive is a flame-retardant additive UV-531 master batch, perhaps is anti-aging, uvioresistant additive HA88-NEW master batch.
Its composition of raw materials is: 100 kilograms of PP particles, add the PE particle of 20%-40%, and add the UV-531 master batch of 1%-5% or the HA88-NEW master batch of 1%-5% again.
The concrete prescription of its raw material is: 100 kilograms of PP particles, add 30% PE particle, and add 2% UV-531 master batch or 2% HA88-NEW master batch again.
The advantage that the utility model is compared with prior art possessed:
The one, the tensile strength height.When twisting thread, increase the autobalance tensioner, make every monofilament no longer encircle song and producing balanced forces has improved the hawser brute force significantly.Detect according to relevant authoritative department, the hawser standard brute force of diameter 40mm is 20100daN, and the hawser detection of the same specification of producing behind the increase tensioner is 23890daN.
The 2nd, high temperature resistant.Original simple PP particle reeled off raw silk from cocoons now change PP/PE/UV-531 or PP/PE/HA88-NEW into; just 100 kilograms of PP particles add 30% PE particle and add 2% UV-531 master batch or HA88-NEW master batch again; the hawser that makes after reeling off raw silk from cocoons is high temperature resistant, anti-aging and uvioresistant, the use model that has improved polypropylene fibre network yarn hawser greatly with and service life.
Specific implementation method
Processing method of the present invention and process route thereof are:
Raw material--wire drawing----plying--rope making-heat treatment typing--plastic-coated of twisting thread.
Described raw material is made up of PP particle, PE particle and additive.Its additive is a flame-retardant additive UV-531 particle, perhaps is anti-aging, uvioresistant additive HA88-NEW particle.
The concrete prescription of its raw material is: per 100 kilograms of PP particles, add 30% PE particle, and add 2% UV-531 master batch or 2% HA88-NEW master batch again.
Above-mentioned PP particle is the third logical sequence master batch raw material, and the PE particle is second logical sequence master batch raw material.The present invention is owing to having added fire proofing and anti-aging, ultraviolet ray-resistant material, so the hawser product that makes can at high temperature use in third logical sequence and second master batch raw material.
In the twisting technique process, in the back of the every group of support of twisting thread the autobalance tensioner is installed, make every monofilament of twisting no longer encircle song, and keep straight tensioning, evenly merge.Pool capital again behind the rope yarn shallow bid of formation 2mm earlier after merging, finish ropework.After rope was made, by the heat treatment typing, promptly by Electric heat oven, temperature remained on about 200-210 ℃, through heating in 5 seconds.After typing is finished, the extexine of hawser is carried out plastic-coated again handle, promptly finish whole processes.
The present invention is owing to installed the autobalance tensioner in the back of the every group of support of twisting thread, make every monofilament of twisting no longer encircle song, and keep straight tensioning, evenly merge, so hawser that makes, each root monofilament in use can both bear its working pulling force simultaneously, so strengthened the tension brute force of hawser greatly.
