Abstract
The present invention provides a high corrosion resistance and high strength composite steel wire and a manufacturing process thereof, which is mainly used for steel-cored aluminium strand wires or steel strand wires. In the composite steel wire, organic silicon paint is coated on the surface of a steel core wire or a steel strand wire; after the composite steel wire is solidified by a low temperature process to form a film, the surface of the steel wire is transparent and has good corrosion resistance. The composite steel wire has manufacturing process, simple technology and low cost. The present invention can be widely used for other manufacturing industries, such as the manufacturing industries of sheet materials, pipe materials, section materials and pipe fittings.
Description
(1) technical field
The present invention relates to a kind of high anti-corrosion, high-intensity NEW TYPE OF COMPOSITE wire rod, be specially adapted to the reinforcement steel core wire or the steel strand wire of aerial condutor.
(2) background technology
At present, being used for the steel wire of steel reinforced aluminium conductor and steel strand wire both at home and abroad, mainly is at Steel Wire Surface hot-dip layer of aluminum kirsite, and having used with standardized product has: 55%Al-Zn and 5%Al-Zn alloy product steel wire.In recent years, in order further to improve the anti-corrosion effect of steel wire, domestic interpolation rare earth or the new alloy coating wires such as Mg, Sn developed in succession again.But these goods steel wires still can not satisfy user's needs, its main cause: the one, the low-melting-point metal of existing Steel Wire Surface immersion plating or alloy all can with acid, alkali, the salt fog medium chemically reactive in the atmosphere, just corrosion rate difference; The 2nd, molten alloy temperature in the hot-dip metal production technology causes the tensile strength of immersion plating steel wire to descend.
(3) summary of the invention
The purpose of this invention is to provide a kind of anti-corrosion weather resistance excellence, mechanical properties of wires is unaffected and the NEW TYPE OF COMPOSITE wire rod of low production cost.The present invention adopts modified silicone-resin-base paint as external coating, is applied to the Steel Wire Surface after the phosphatization, and low temperature process forms a kind of NEW TYPE OF COMPOSITE steel wire after solidifying.
The class coating material that the present invention adopts is a modified silicone-resin-base paint, and is the most suitable with transparent methyl silicon resin.These organosilicon coatings can mix in a big way with organic solvent, so that adjustment viscosity, be easy to coating, and curing time is short, temperature low (below 80 ℃), the film forming rear surface is smooth, resistance to chemical attack and atmospheric corrosion, anti-ly scratch, heat-resisting, cold-resistant, ageing-resistant, anti-solvent, resistance to water etc., the steel wire manufactured goods after the coating have kept the original mechanics parameter of steel wire constant.In manufacturing process, adopted first phosphatization passivation, after the technical process of filming, make film forming firmly combine with the steel wire matrix, energy resource consumption also reduces (more than 70%) greatly than the immersion plating coat of metal.For the holiday phenomenon that manufactured goods occur sometimes, can adopt local brushing or spraying to repair easily.
Key of the present invention is the Steel Wire Surface in the phosphatization passivation, the coating modified silicone-resin-base paint.The compositing formula of modified silicone-resin-base paint is: methyl silicon resin 15-30%, ethanol and butanols 65-80%, triethylene tetramine or TEPA 0.15-1.5%, dibutyl phthalate or dioctyl phthalate 1.0-3.0%.Manufacturing process of the present invention is first phosphatization passivation steel wire matrix, floods coating again, and the solvent cooling is reclaimed in the film-forming process, and the whole operation process is worked continuously.
Manufacturing process flow of the present invention is as follows:
(4) embodiment
Manufacturing process embodiment of the present invention is as follows:
1, being coated with steel wire is φ 3.0 high-carbon steel wires
2, formulation for coating material (wt%):
SAR-5 methyl organic siliconresin 25%
Absolute ethyl alcohol 49%
N-butanol 23%
Dibutyl phthalate 2%
Triethylene tetramine 1%
3, technological process:
(1) steel wire oil removing
(2) washing → phosphatization → cleaning → oven dry
(3) dipping coating (15-20s)
(4) draw and extract (the nib limit is thick)
(5) curing oven dry (75 ℃, 2min)
(6) take-up obtains finished product
(7) the solvent cooling is reclaimed
4, product detects:
| Sequence number | Test event | Test result |
| ① | Immerse 5% boiling NaCl solution 8h | No change |
| ② | Saturated H 2S gas 30min | No change |
| ③ | Immerse 25 ℃ of 10d of 1%NaOH solution | No change |
| ④ | The aging ultraviolet illumination-50 of 250 ℃ of 1000h is ℃ cold-resistant | Not efflorescence of rete, nondiscolouring is not chapped |
| ⑤ | Relative humidity is greater than 95% 38 ℃ of 72h | No change |
| ⑥ | Crooked 180 ° of adhesive force | Coating does not have and comes off |
| ⑦ | Before and after the tensile strength dip-coating | No change |
| ⑧ | The 8 times of 5-10 circles in wrapping test line footpath | Do not ftracture |
| ⑨ | Coating thickness | 7.4×10 -5m |
The invention solves and be used for the problem that built on stilts steel reinforced aluminium conductor or steel strand surface for a long time can not be anti-corrosion; Solved the problem that causes the immersion plating mechanical properties of wires to descend because of or immersion.This composite steel wire surface quality height is coated with membrane lifetime and reaches more than 10 years, has been applicable to acid, alkali, salt, the high temperature humidity, and low temperature is cold complicated occasion such as to freeze, and compares with immersion gilding metal products steel wire technology, and energy consumption, weight reduce greatly.To holiday or rupture of membranes, repair quick, convenient.Technology of the present invention also is applicable to wire, sheet material, tubing, pipe fitting and the section bar that applies other.
Claims (1)
