Abstract
The invention provides a kind of composite steel band without cladding material and manufacture method thereof, this composite steel band is made up of basic unit's cold-rolled strip and the plastic foil that is compounded in respectively on its two sides, its manufacture method be earlier steel strip surface is eliminated rust, oil removing, high temperature oil removing, temper softening and the processing of turning blue, with the composite plastic film that pressurizes after the steel band preheating, heat treatment composite steel band then, cooling at last makes again.This method has been save chrome-plated process, prevents the environmental pollution that produces because of chromium plating, and reduces its chromium plating expense, can reduce the cost of composite steel band greatly, and product is mainly used in the vertical bag and the armouring of cable and optical cable in the line cable industry.
Description
The present invention relates to a kind of mask tape and manufacture method thereof of cable, particularly relate to composite steel band without cladding material and manufacture method thereof.
Steel/the plastic composite strip that is used at present cable shielding both at home and abroad has been the coating composite steel band, i.e. composite plastic film again after steel strip surface covers layer of metal coating, its coating can be zinc-plated, zinc-plated, chromium plating etc., be generally chromium coating, its reason is the steel strip surface easy-to-rust, and that iron rust combines with unattacked part is loose, is easy to peel off, above plastic foil can not being compounded in.The method of conventional available oiling prevents the steel band corrosion, and this causes the wetability variation of steel strip surface again, also can not be compound, therefore adopt chrome-plated process.Cleaned the steel strip surface greasy dirt on the one hand, can prevent simultaneously that steel strip surface from producing corrosion, even and the oxidized generation oxide-film in chromium coating surface, but oxide-film and not oxidized coating surface also have very strong adhesion, and plastic foil and chromium plating steel band are bonded together securely.Since adopt big segment length steel band as thin as a wafer, the chrome-plated process complexity, and China can't produce now, and the cost height, mainly from external import.
The object of the present invention is to provide a kind of can be directly after steel strip surface is handled the composite steel band without cladding material of composite plastic film and manufacture method thereof in its surface.
Composite steel band without cladding material of the present invention is made up of basic unit's cold-rolled strip and the plastic foil that is compounded in respectively on its two sides.Wherein cold-rolled strip thickness is below 0.20mm, and more than the width 200mm, length is non junction more than 2000 meters.Plastic foil generally is a polyethylene, ethylene-vinyl acetate copolymer, and the ethylene-propylene acid copolymer is as ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer etc.Its thicknesses of layers is generally 0.045-0.055mm.
The manufacture method of composite steel band without cladding material of the present invention is; steel strip surface is handled; promptly the hydrochloric acid with 2-5% cleans steel strip surface; remove iron rust; remove rolling machine oil with gasoline again; in 450～600 ℃ of temperature ranges, under inert gas shielding, remove residual oil then; being warming up to 600～800 ℃ handles the steel band temper softening; treat to feed when temperature is reduced to 500 ± 50 ℃ nitrogen oxygen mixed gas; make steel strip surface send out orchid, form the tri-iron tetroxide oxide-film of one deck densification, be attached to steel strip surface securely; the protection steel strip surface combines very tight simultaneously not by corrosion with plastic foil.Steel band after the processing is low excessively in preheating in 70-120 ℃ of temperature range before the composite plastic film, temperature, and is bonding not firm with plastic foil, and the composite steel band peel strength reduces, and temperature is too high, and the compound tense resin can produce thermal contraction and pile up, and makes composite membrane inhomogeneous smooth.Composite plastic film can adopt dual mode, i.e. hot pressing is compound and hydrostomia is compound.Hot pressing is compound generally to be in 2-4kg/cm with the finished product plastic foil
2Hot pressing is compound in steel strip surface under the pressure, and hypotony causes two kinds of layers of material, and hypertonia can make the rubber roller distortion or damage, and makes it can not be fine bonding, and influences surface quality.Hydrostomia is compound then to be copolymer resin to be heated to melt temperature make it to be molten condition, and hydrostomia forms plastic foil on the steel band of preheating again, and in 2-4Kg/cm
2Pressure pressurization down is compound.Steel band after compound is heat-treated again, generally is advisable with 100-160 ℃, and about 5-8 second heat time heating time, temperature is low excessively to make composite steel band peel strength and heat seal strength not reach standard, and temperature is too high to make the bipolymer degraded, causes heat seal strength to descend greatly.Be cooled to room temperature at last and make composite steel band without cladding material.The type of cooling can adopt cold wind to force cooling, or with water chill rolls composite steel band is lowered the temperature.For preventing that its composite steel band edge corrosion from also can carry out naked limit and handling, generally adopt the two component corrosion resistant coatings of brush plating chromium or brush.
The invention has the advantages that and save chrome-plated process, prevent the environmental pollution that chromium plating produces, and reduce its chromium plating expense, reduce the cost of composite steel band greatly, its technical target of the product all reaches chromium plating composite steel band standard, is mainly used in cable, cable armor and vertical bag.
Describe the present invention in detail below in conjunction with embodiment.
Embodiment 1: the rusty scale of removing the cold-rolled strip surface with the hydrochloric acid of concentration 3%; after removing its rolling machine oil with aviation gasoline again; in 450 ℃ of further high temperature oil removings under inert gas shielding; carry out temper softening at 600 ℃ then and handle, be cooled to 510 ℃ of feeding nitrogen oxygen mixed gas and make its surface send out orchid.With the steel band after handling in 70 ℃～90 ℃ temperature-gradient method preheatings, at 2.5kg/cm
2Hot pressing compound ethylene-acrylic copolymer film is on steel band under the pressure, at last 155 ℃ of 7 seconds of heat treatment composite steel band, be cooled to 15 ℃, make composite steel band without cladding material, its technical indicator is as shown in table 1.
Embodiment 2: the rusty scale of removing the cold-rolled strip surface with the hydrochloric acid of concentration 5%; after removing its rolling machine oil with aviation gasoline again; in 550 ℃ of further high temperature oil removings under inert gas shielding; under 750 ℃ of temperature, carry out temper softening then and handle, be cooled to 490 ℃ of feeding nitrogen oxygen mixed gas and make its surface send out orchid.Steel band after the processing is in 90～120 ℃ of temperature-gradient method preheatings, with low density polyethylene (LDPE) in 245 ℃ of fusion hydrostomias on steel band, in 3Kg/cm
2Make the salivation film heat posted under the pressure on steel band, at last 120 ℃ of 8 seconds of heat treatment composite steel band, be cooled to 15 ℃, make composite steel band without cladding material, its technical indicator is as shown in table 1.
