Problems solved by technology

[0002] In the existing technology, the shielding performance of the composite strip used for electric cables and optical cables is poor at present, and there are often phenomena such as noise and crosstalk, and the anti-interference ability is poor, and it has high requirements for the use environment. In general environment, it is easy to be affected by moisture and easy to corrode, which greatly reduces the service life and virtually increases the production cost
At the same time, the heating temperature of the general composite tape is relatively strict in the production process of cables and optical cables. The entire production and processing process is complicated and cumbersome, and the product quality often does not meet the requirements.

Abstract

The invention relates to a production method of a double-sided stainless steel composite band. A stainless steel band and a PE (polyethylene) plastic film are selected as raw materials and subjected to an unwinding procedure, a preheating procedure, a compounding procedure, a cooling procedure, a winding procedure, a slitting procedure, a finished product inspection procedure and the like to finally form a finished double-sided stainless steel composite band which is used as a material for manufacturing electrical cables and optical cables. The double-sided stainless steel composite band produced by the invention is good in shielding performance, strong in anti-interference capability, low in initial bonding temperature, high in heat-seal bonding performance and good in conductivity.

Description

technical field [0001] The invention relates to a production method of a double-station double-sided stainless steel composite belt, in particular to a shielding material suitable for the manufacture of optical cables, and belongs to the technical field of heat paste composite manufacturing. Background technique [0002] In the existing technology, the shielding performance of the composite strip used for electric cables and optical cables is poor at present, and there are often phenomena such as noise and crosstalk, and the anti-interference ability is poor, and it has high requirements for the use environment. Under normal circumstances, it is susceptible to moisture and corrosion, which greatly reduces the service life and virtually increases the production cost. At the same time, the heating temperature of the general composite tape is relatively strict during the production process of electric cables and optical cables. The entire production and processing process is co...
