Layer.
Preferably, the thickness of described epoxy coating is 0.2～0.4mm, and test finds that the epoxy resin of this thickness is coated with
The anticorrosive life-span of layer up to more than 50 years, and in steel wire ultimate tensile strength, reverse, bend, under the conditions of winding etc.
Will not ftracture, be layered, the phenomenon such as peeling.
Further, in described zinc-aluminium coating, aluminum content is 4.2～7.2wt%, and " bridge zinc-aluminium closes to meet national standard
Gold plate steel wire cable " requirement in (paper for approval).
Corresponding hoist cable is to be become steel tendon by some hexagonal close-packed arrays of above-mentioned steel wire, continuous along described steel tendon outer
Being wound around polyester fiber band, and external pe sheath, the steel wire outer layer stretched in cable body in fixing anchor cup divests asphalt mixtures modified by epoxy resin
Fat coating, between anchor cup inner chamber and steel tendon, filling epoxy resin filler is to form HiAm anchorage or to fill pltine to be formed
Hot casting anchor.
Above-mentioned hoist cable zinc-aluminium coating and the preparation method of steel wire thereof of epoxy coating, concrete technology includes: by wire rod through hanging
Bright steel wire after pulling out immerses in melted allumen liquid, zinc-aluminium coating on bright steel wire plated surface, zinc-aluminium coating
Unit mass >=300g/m2, in zinc-aluminium coating, the content of aluminum is 4.2～7.2wt%；Then surface is coated with zinc-aluminium coating
Steel wire carries out electrostatic spraying epoxy coating and forms epoxy coating, utilizes the physical phenomenon of electrophoresis, makes the ring of atomization
Epoxy resins coating particles carries negative charge in DC high voltage electric field, and under the effect of electrostatic field, is just directionally flowing to band
Electric charge Zn-Al Alloy Coated Steel Wire, the heated melted formation of the most mutual NA powder particle is uniform, smooth, light
Sliding coating, the thickness of epoxy coating is 0.2～0.4mm, obtains steel wire finished product.
Preferably, after zinc-aluminium coating completes, use saponification liquor to zinc-aluminium coating surface degreasing, and at electrostatic spraying ring
Before epoxy resins coating, steel wire is preheated, to improve electrostatic spraying effect, make epoxy coating and zinc-aluminium coating it
Between the most relatively reliable, prevent cracking, separate.
Described epoxy coating mainly includes epoxy resin, firming agent, filler, pigment and flow-control agent.
Compared with prior art, the utility model has the advantage of:
(1) Steel Wire Surface constituting hoist cable is provided with zinc-aluminium coating and epoxy coating from inside to outside, significantly improves
