Abstract

The invention discloses an aluminum alloy prefabricated branched cable and a preparation method thereof, wherein the cable material comprises the following raw materials of high-density polyethylene,butyl rubber, terpolymer EP rubber, urea-formaldehyde resin, nipol carboxy lated nitrile, polytetrafluoroethylene, polycarbonate, dialkyl phosphoric acid, polypropylene, styrene, dicumyl peroxide, chloroform, polyethylene glycol, magnesium carbonate, antimony oxide, rectorite, multi-wall carbon nanotube, nanometer montmorillonite, calcium nitrate, carbon black, graphite, hydroxyapatite, nanometersilicon dioxide, calcium chloride, potassium sulfate, trioctyl trimellitate, aluminium triphosphate, silane coupling agent KH-570, a promoter TMTM, an antioxidant ODA, glycerin and benzotriazol. The aluminum alloy prefabricated branched cable is prepared through the cable material. The preparation method comprises the steps of connecting a main cable with branch cables, performing injection molding of the main cable and the branch cables, etc. The aluminum alloy prefabricated branched cable has advantages of low-temperature resistance, high-temperature resistance and excellent toughness.

Description

【Technical field】 [0001] The invention belongs to the technical field of cable preparation, and in particular relates to an aluminum alloy prefabricated branch cable and a preparation method thereof. 【Background technique】 [0002] The aluminum profile process is to place the activated plated parts in an aqueous solution of salt and hydrochloric acid for chemical treatment. Although the aluminum profile has a certain corrosion resistance, the high temperature resistance of the aluminum profile is not good during use, so that the life of the aluminum profile is low and the use effect is not good when it is used in a high temperature environment. [0003] The Chinese patent application document "An Aluminum Alloy Prefabricated Branch Cable (Application Publication No.: CN104021860A)" discloses a method for preparing an aluminum alloy prefabricated branch cable, which includes the following steps: (1) making the main cable and the branch cable; (2) Connect the main cable and t...
