preparation example Construction
[0013] The invention provides a preparation method of an anti-aging cable packaging film, comprising:
[0014] 1) ultrasonically vibrate aluminum oxide, sodium dodecylbenzenesulfonate, tea polyphenols and water, then filter and dry the filter cake to prepare the composition;
[0016] 3) kneading and molding the packaging material to obtain the anti-aging cable packaging film.
[0017] In step 1) of the present invention, the consumption of each material can be selected in a wide range, but in order to further improve the anti-aging performance of cable packaging film, preferably, in step 1), aluminum oxide, dodecylbenzene The weight ratio of sodiumsulfonate, tea polyphenol and water is 50:10-15:6-9:100-150.
[0018] In step 1) of the present invention, the conditions of ultrasonic ...

Abstract
The invention discloses an anti-aging cable packaging film and a preparation method thereof. The preparation method comprises the following steps: 1) performing ultrasonic vibration on aluminum oxide,sodium dodecyl benzenesulfonate, tea polyphenol and water, then performing filtering to obtain a filter cake and drying the filter cake to obtain composition; 2) mixing polyvinyl chloride, styrene-butadiene rubber, paraffin, palm oil, iso-octyl methacrylate, talcpowder, methyl cellulose and the composition to prepare a packaging material; 3) mixing and molding the packaging material to preparethe anti-aging cable packaging film. The cable packaging film has excellent anti-aging performance, and the preparation method has the advantages of simple process and easily available raw materials.
Description
technical field [0001] The invention relates to cables, in particular to an anti-aging cable packaging film and a preparation method thereof. Background technique [0002] The cable is mainly composed of the following four parts. Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be twisted by a single wire or multiple wires; insulation layer: the insulation material used for cables should have high insulation resistance and high breakdown electric field strength, low dielectric loss and low dielectric constant. Sealing sheath: protect the insulated wire core from mechanical damage, moisture, moisture, chemicals, light, etc. For moisture-prone insulation, lead or aluminum extruded sealing sheaths are generally used; protective covering: used to protect the sealing sheath from mechanical damage. [0003] Existing cables need to be coated with a packaging...
