Problems solved by technology

However, the flame-retardant tapes in the prior art are large in size and heavy in weight, so they are expensive, and the industry is in urgent need of alternative products, and there is currently no alternative product on the market
On the other hand, when the existing aluminum-plastic composite tape is used in the signal cable, it is usually wrapped longitudinally or around the cable core. The aluminum layer and the plastic layer of the aluminum-plastic composite tape in the prior art are easy to separate, which affects the product quality. emotional energy

preparation example 1

[0019] The present invention will be described in further detail below with reference to the accompanying drawings; Preparation Example 1 and Preparation Example 2 are examples of preparing aluminum-plastic composite tapes according to the present invention, and Example 1 is an embodiment of the system for manufacturing aluminum-plastic composite tapes according to the present invention.

preparation example 1）

[0021] See figure 1 and figure 2 , the aluminum-plastic composite tape of this preparation example is composed of an aluminum foil layer 1, an adhesive layer 2, and a plastic film layer 3. The adhesive layer 2 is located between the aluminum foil layer 1 and the plastic film layer 3, and bonds the aluminum foil layer 1 and the plastic film layer 3 together. The thickness of the aluminum foil layer 1 is 0.01-0.05mm. The thickness of the plastic film layer 3 is 0.005-0.05 mm, and the plastic film layer 3 is a polyester tape layer. The adhesive layer 2 includes the following materials in parts by weight: 100 parts of epoxy resin, 6-15 parts of butylene phthalate or phospholipid diphenol ester, 2-5 parts of polyamide resin, silane coupling 2-5 parts of epoxy resin, 3-3 parts of epoxy curing agent, 1-3 parts of magnesium oxide, 2-5 parts of glycerin epoxy resin, 2-5 parts of aluminum oxide, and 3-8 parts of aluminum hydroxide. The adhesive layer 2 is continuously distributed b...

Abstract

The invention relates to a system used for manufacturing an aluminum plastic composite belt with adhesive layers of interrupted distribution and adopting a gas pressure source. The aluminum plastic composite belt is formed by bonding the adhesive layers between an aluminum foil layer and a plastic film layer. The adhesive layers are distributed between the aluminum foil layer and the plastic film layer in an interrupted mode. The system comprises an aluminum foil layer discharging device, a plastic film layer discharging device, a composite belt forming device, a drying device, a composite belt traction device and a composite belt winding device. The composite belt forming device comprises a working platform, a plastic film layer rolling device, an adhesive layer spraying device, a composite belt forming device and an adhesive supply device. Pressure of a pressure supply source connected with a pressure transmitting device of the adhesive supply device is formed by gas. The gas is nitrogen or inert gas. The system is simple in structure, low in cost and easy to maintain.

Description

[0001] The present invention is a divisional application of the invention patent application with the application number 201310049527.9, the application date is February 7, 2013, and the invention title is "a kind of aluminum-plastic composite belt and its manufacturing system". technical field [0002] The invention belongs to the technical field of cable materials, and in particular relates to an aluminum-plastic composite strip manufacturing system. Background technique [0003] With the popularity of the communication industry and power transmission, the application of cables is becoming more and more extensive. In signal cables, aluminum-plastic composite tapes are often used to cover the cable core to make the cable core more round. At the same time, the conductors in the cable core The transmitted electrical signal is shielded. In power cables, flame retardant tapes are used for fire prevention and flame retardant. However, the flame-retardant tapes in the prior art ...
