Description
Technical field
The utility model relates to rubber product technical field, in particular to a kind of enhanced fiber winds rubber tube.
Background technique
High pressure wire braided hose be generally used for engineering construction, lifting transport, injection machine, agricultural machinery, lathe and
Conveying has petroleum base (such as mineral oil, solvable of certain pressure and temperature in each industrial department mechanization, automation hydraulic system
Property oil, hydraulic oil, fuel oil, lubricating oil) liquid, water fluid (such as emulsion, oil-water emulsion, water), gas and liquid passes
It employs.Current high pressure wire braided hose is usually synthetic rubber internal layer, mesoglea, compound steel silk braiding layer and synthetic rubber
Outer layer is constituted, and synthetic rubber internal layer, which has, makes pumped (conveying) medium bear pressure, the effect for protecting steel wire not weather, however, defeated
When sending high pressure gas, steel wire braid is easy to produce embrittlement phenomena, also has using Resin Wound layer structure, still, Resin Wound
Layer rigidity is insufficient, and under high pressure gas effect, internal layer is squeezed expanding deformation, and Resin Wound layer bearing capacity is less than normal, is squeezed
Deformation, shortens the working life, durability is poor.
Utility model content
In view of the deficiencies of the prior art, the technical problem to be solved is that provide a kind of enhanced fiber to twine for the utility model
Around rubber tube, Resin Wound layer structure is used, rigidity and flexibility are taken into account, bearing capacity is strong, and resistance to deflection is good, durable use.
The utility model is to be addressed above-mentioned technical problem by the following technical programs.
A kind of enhanced fiber winding rubber tube successively includes rubber inner layer, RFL latex layer, the first winding from the inside to the outside
Layer, the second winding layer and rubber outer, the first winding layer and the second winding layer are twisted and plied complex yarn spiral winding knot
Structure, twisted and plied complex yarn are formed by several strands of filament yarn doubling doubling twistings, and filament yarn is by two PEN monofilament and one
Root PET monofilament is twisted.Wherein, RFL latex layer is resorcinol-formaldehyde-latex.
Preferably, reverse winding arrangement each other between the first winding layer and the second winding layer.
Preferably, the fiber number of PEN monofilament and PET monofilament is 1500dtex to 3000dtex.
Preferably, twisted and plied complex yarn is formed by three to stereotyped writing filament yarn doubling doubling twisting.
Preferably, the spiral angle of the first winding layer and the second winding layer is 45 degree to 60 degree.
Preferably, rubber inner layer is NBR, HNBR, NBIR or BIMS rubber material.
Preferably, rubber outer is SBR, CR, EPDM or CSM rubber material.
Preferably, rubber inner layer with a thickness of 0.5mm to 4mm.
Preferably, rubber outer with a thickness of 0.5mm to 3mm.
The utility model has the beneficial effects that
1. taking into account and examining to improve rigidity and bearing capacity using double-deck twisted and plied complex yarn spiral winding structure
The feature that PEN filament properties are good, at high cost is considered, so that twisted and plied complex yarn was combined using PEN monofilament and PET monofilament
Compound resin fiber not only reduces material cost, and winding layer intensity, enhancing resistance to compression compression deformation is greatly improved and resists
Torsional deformation ability, is less prone to compressive deformation, prolongs the service life.
2. reverse winding arrangement each other between the first winding layer and the second winding layer, is beneficial to enhance anti-twist deformation, mention
High bearing capacity.
3. removing mesoglea between the first winding layer and the second winding layer, material cost is reduced, mitigates weight, improves flexure
Property.
