Embodiment 1

[0022] A method for producing a hot-melt adhesive aluminum-plastic composite tape of 9 μmA1 / 23 μm plastic film / 9 μmA1 / Green HC specification, the processing steps are as follows:

[0023] 1) Aluminum foil and plastic film compound semi-finished product: on a dry compound machine, use polyurethane glue to compound 9μm aluminum foil and 23μm plastic film together, put it in the curing room for 12-72 hours, and then cool it at room temperature for more than 24 hours , that is to complete the aluminum foil and plastic film composite semi-finished product.

[0024] 2) Dilution of hot melt adhesive: hot melt adhesive refers to a viscous liquid made of polyester, ethyl acetate, butyl acetate, butanone, etc., which are reacted in a chemical reaction furnace according to a certain proportion, and the solid content is 5- 80%, the viscosity is 10-5000mPa.S. Hot melt adhesive has good adhesion to PVC and plastic film, and the peel strength is ≥10N / 20mm. The hot melt adhesive has a high ...

Embodiment 2

[0036] A method for producing a 9μmA1 / 23μm plastic film / 9μmA1HC hot-melt adhesive hot-melt aluminum-plastic composite tape, the processing steps of which are as follows:

[0037] 1) Aluminum foil and plastic film compound semi-finished product: on a dry compound machine, use polyurethane glue to compound 9μm aluminum foil and 23μm plastic film together, put it in the curing room for 12-72 hours, and then cool it at room temperature for more than 24 hours , that is to complete the aluminum foil and plastic film composite semi-finished product.

Abstract

The invention discloses a method for producing a hot-melt-adhesive aluminum-plastic composite tape. The method provided by the invention comprises the following steps of: manufacturing a composite semi-finished product of aluminum foil and plastic thin film, preparing a hot melt adhesive, coating the hot melt adhesive, drying the hot melt adhesive, cooling, coiling, and cutting. On the productionline of a PVC (Poly Vinyl Chloride) cable sheath, the hot-melt-adhesive aluminum-plastic composite tape and the sheath material can be bonded together by utilizing the temperature of the sheath when the PVC cable sheath material is extruded; the adhesive force is strong and the testing performance is good; and when a user strips the cable PVC sheath, the hot-melt-adhesive aluminum-plastic composite tape can be easily stripped so that the procedure of stripping two times is omitted, the mounting time is greatly saved and the damage on the cable is reduced. The hot-melt-adhesive aluminum-plastic composite tape manufactured with the method can be widely applied to a communication cable industry, and can propel the application reformation of the communication cable industry on the hot-melt-adhesive aluminum-plastic composite tape and also exploit a new application market of the hot melt adhesive.

Description

technical field [0001] The invention relates to a method for preparing shielding materials for communication cables, in particular to a method for producing aluminum foil polyester composite materials. Background technique [0002] At present, the common aluminum-plastic composite tape on the market needs to peel off the outer skin of the cable when the customer installs the cable joint, and then peel off the aluminum-plastic composite tape. The stripping of the aluminum-plastic composite tape is time-consuming and easy to damage the cable. Contents of the invention [0003] In view of the defects in the above-mentioned prior art, the purpose of the present invention is to propose a production method of a hot-melt adhesive aluminum-plastic composite tape, so that the produced hot-melt adhesive aluminum-plastic composite tape can be tightly bonded to the outer skin of the cable to solve the problem of Damage to the cable when the outer skin of the cable is peeled off.
