Abstract

The present invention relates to a method for making a metallic shielding composite strip for optical cables and electric cables. The method mainly solves the problems of the swelling, leaking, stripping, strip breaking, etc. of optical cables and electric cables easily caused by large frictional force between the contact surfaces of a shielding composite strip made by using an existing method and an optical cable and electric cable longitudinal covering mould or an east longitude mould. Through the uneven rough surface hot extrusion bonding of the surfaces of a plastic film and a metal foil strip, the composite strip forms point contact with an optical cable and electric cable longitudinal covering mould or an east longitude mould to reduce frictional force and to improve the quality of products. The method for making the metallic shielding composite strip comprises the following processes: firstly, a plastic fused mass or a plastic film passes through the space between a fine mesh steel roller with a rough surface and a squeeze roller to be formed into an uneven rough surface with broom-finishes, and the uneven rough surface is hot extruded on the base material of a metal foil strip; then, the composite strip experiencing composite treatment is post heated; finally, cooling and rolling are carried out. When in use, the composite strip made by the present invention has the advantages of flatness, straightness, smoothness, no knife scratches and picot edges, high peel strength, no swellings, delamination, strip breakage and stripping and stable performance, and can be widely used in various optical cable and electric cable manufacture companies.

Description

The manufacture method of smooth-type compoiste metallic shielding belt
The present invention relates to telecommunications material technology field, a kind of specifically manufacture method that is used for the metallic shield composite band between optical cable, cable outside and the outermost layer sheath.
At present, the method for making optical cable, cable outer layer metallic shield composite band roughly has three kinds: the one, and curtain coating figure cloth composite algorithm, the 2nd, dry type composite algorithm, the 3rd, heat posted method.Wherein, curtain coating coating composite algorithm, be with plastic master batch after plastic extruding machine heating, plasticizing, be squeezed on the metallic foil by the mould plastic-coated, make the product peel strength reach requirement through reprocessing again.Though the composite band that this method is made is stable and reliable for performance, does not have stripping phenomenon, the cost height is difficult for grasping complex process.The dry type composite algorithm is that set plastic film is bonded in plastic film on the metallic foil with adhesive, make the product peel strength reach requirement through reprocessing again, the shortcoming of this method is that adhesive is aging easily, loses efficacy, and product quality can not be protected for a long time.The heat posted method also is with set plastic film, pastes by metallic foil heating back and plastic film to press together.The shortcoming of this method is the quality instability, yields poorly.The common defects that the metallic shield composite band that these three kinds of processes are produced exists is, plastic film and metal forming belt be pure flat bonding, making it in use form the composite band surface contacts with optical cable, the vertical face that wraps between mould or the sizing mould of cable, thereby frictional force strengthens, and causes the problems such as bag, gas leakage, demoulding, broken belt that rise of optical cable, cable easily.
It is little to the purpose of this invention is to provide a kind of frictional force, can pass through optical cable, cable vertical bag mould or sizing mould smoothly, and does not have the metallic shield composite band manufacture method of belt phenomenon.
The key problem in technology of realizing the object of the invention be with plastic film and metallic foil surface carry out rough non-pure flat bonding, make to form to put between composite band and optical cable, cable vertical bag mould or the sizing mould and contact, to reduce friction, avoid cable to play problems such as bag, gas leakage, demoulding and broken belt.
Its process is as follows:
(1) the virgin metal paper tinsel roll coil of strip is stretched out, carry out preceding The pre-heat treatment;
(2) be 35 ℃-80 ℃ with plastic melt or plastic film by temperature, diameter is Φ 240mm-Φ 600mm, the order number is 40 orders-85 a purpose matsurface detailed catalogue steel rider, with diameter be the compression roller of Φ 160mm-Φ 480mm transmission metallic foil, rotate mutually, make the surface of plastic film form the thick uneven matsurface of 0.04-0.09mm, hot extrusion is on the base material of metallic foil one side;
(3) metal forming that will have plastic film through swinging to the roller turn-over, is carried out plastic film hot extrusion Combined Processing to the another side metal forming again through deflector roll, spring roll transmission;
(4) be that the deflector roll of 10m/min-80m/min enters heated oven with the composite band after the Combined Processing by travel line speed, carry out the back heat treated, the temperature of heating is 250 ℃-400 ℃;
(5) according to drive line speed, adjust heating-up temperature, the roughness that makes composite band is destroyed minimum in the operation processing procedure of back, and makes the frosting of plucking form the uneven matsurface of new band arc transition, with the peel strength of strengthening composite band and the typing of plastics plasticizing;
(6) composite band that the back heat treated is crossed is carried out cooling processing and rolling.
The back heat treated of said method is by adjusting the adjustable plate distance in the heated oven, its composite band is presented a little less than the reflectance, is smooth to the touch, smooth outer surface.
Making apparatus of the present invention mainly by plastic extruding machine, deflector roll, compression roller, detailed catalogue steel rider, swing to roller, heated oven is formed.Wherein, the appearance hair side structure of detailed catalogue steel rider, compression roller is the nonmetal roller that rubber, plastics king or fluoroplastics are made, and is provided with the adjustable plate of regulating temperature in the heated oven.
The present invention is owing to adopted plucking to plastic film, to form the Combined Processing operation of uneven matsurface, thereby, making composite band produce the very little point of frictional force with the vertical bag mould of optical cable, cable with the sizing mould contacts, can be smooth pass through mould, greatly reduce the possibility of broken belt, improved the product quality of optical cable, cable.Actual measurement shows, the composite band appearance surfaces of making of the present invention has the uneven matsurface of visible garden arc (be smooth to the touch, smooth), the equal composite demand value of every technical indicator.Practicality shows, uses straight, level and smooth, the no tool marks of composite band, no scollop, scallop, peel strength excellence that the present invention makes, do not play bag, not stratified, broken belt not, no demoulding, stable performance.Can be according to the requirement of optical cable, cable, can be optional between the 500m-600m in composite band length, do not have joint is arranged, be widely used in national 70 cable production units.
