Embodiment 1

[0034] The manufacture process of the present invention is as follows:

[0035] 1. Select an aluminum foil with a thickness of 0.12mm±0.005mm as the aluminum base belt, according to figure 1 The process of tape casting coating composite pretreatment.

[0036] The process of composite pre-treatment is as follows: firstly, the aluminum base strip roll is opened, then the aluminum base strip L is flattened, and then preheated. The preheating of the base tape is carried out by an oil heating roller or an electric heating roller, and its temperature is 90-220°C;

[0037] 2. Extrude and compound the aluminum base tape and the plastic with matte smoothness, refer to figure 2 , and its composite process is:

[0038] (1) The aluminum base strip L enters between the first composite pressure roller 1 and the first composite roller 3 .

[0039] The surface of the first composite rubber roller 1 is made of non-metallic material, made of fluoroplastics with a Shore hardness of 40-95, a...

Embodiment 2

[0050] Select aluminum foil with a thickness of 0.10±0.005mm as the aluminum base strip, and make the aluminum-plastic composite strip according to the process of Example 1, wherein:

[0051] The first compound pressing roller 1 adopts non-fluorine plastic roller, so Teflon tape must be pasted on both ends of the non-fluorine rubber roller to prevent the subsequent plastic melt from sticking to both ends of the rubber roller, so as to ensure the normal progress of subsequent rolling and heat sealing .

[0052] When rolling heat sealing, set the working surface temperature of the heat sealing area between the first compound pressure roller 1 and the first compound roller 3 to be 155-290°C, the pressure between the two rollers to be 0.12-1.3Mpa, and the plastic mold adopts 2 layers The co-extrusion mold adopts plastic grade: 0910 resin, whose melting temperature is 180-305°C, and can form 2 layers of plastic film on the A side of the aluminum base tape.

[0053] During the post...

Embodiment 3

[0055] Select the aluminum foil with a thickness of 0.08 ± 0.005mm as the aluminum base strip, and proceed according to the process of Example 1, wherein:

[0056] The first composite pressing roller 1 adopts a fluoroplastic roller.

[0057] When rolling heat sealing, set the working surface temperature of the heat sealing zone between the first composite pressure roller 1 and the first composite roller 3 to be 140-285°C, and the pressure between the two rollers to be 0.11-0.12Mpa.

[0058] The plastic mold adopts a 3-layer co-extrusion mold, the plastic is 30707 grade, and the melt temperature is 185-310°C, which can form a 3-layer plastic film on one side of the aluminum base tape.

[0059] During the post-heating treatment, the temperature of the tape surface is controlled between the Vicat softening point of the plastic and the melting point of the plastic, that is, 84-102°C, and finally a matte smooth aluminum-plastic composite tape with a base tape thickness of 0.08mm is...

Abstract

A process for preparing the dull and smooth aluminum-plastic band includes such steps as choosing an aluminum foil as basic band, pre-treating, extruding out at least one plastic film layer onto one or two surfaces of basic band, rolling while heating, and heat-treating by controlling the temp between Vicat softening point and fusion point for obtain dull and smooth surface. It can be used for optical cable or electric cable for high moisture tight effect.

Description

technical field [0001] The invention belongs to the technical field of telecommunication materials, and relates to a method for manufacturing a metal shielding material between a communication optical cable and a communication cable core and an adhesive sheath, in particular to a matte smooth baseband with a thickness of 0.12 mm to 0.05 mm. The manufacturing method of aluminum-plastic composite tape is suitable for the manufacturing industry of communication optical cables and communication cables. Background technique [0002] It is well known in the industry that when making communication optical cables and communication cables, because the molecular chain of the PE outer sheath is too thick to achieve a real moisture-proof effect, it is necessary to use a metal material with fine molecular chains to set up a shielding layer. The PE outer sheath materials of communication optical cables / cables are bonded together to form an adhesive sheath, which protects the cable core fr...
