Corrosion-resistant and water-blocking aluminum-sheathed single-conductor heating cable and method for preparing same

Abstract

The invention discloses a corrosion-resistant and water-blocking aluminum-sheathed single-conductor heating cable and a method for preparing the same. The heating cable comprises a heat-generating conductor and a group consisting of an XLPE insulating layter, an corrosion-resistant functional coating layer, a PET semiconductor wrapping tape layer, a metal shielding layer, a water blocking layer, an insulation fireproof wrapping tape layer, an aluminum alloy sheath, a neoprene inner sheath, a CPE heat-resistant layer and a neoprene outer sheath which successively coat the heat-generating conductor. The water blocking layer is formed co-extruding an MDPE water-blocking inner layer at the inner side and a LDPE water blocking outer layer at the outer side. The cross-sectional profile of the aluminum alloy sheath is in a gear shape. The heating cable, by structurally optimized design, is greatly improved in thermal efficiency, has good corrosion resistance and water resistance, reduces energy consumption, and has a long service life.

Description

technical field [0001] The invention relates to the technical field of heating cables, in particular to a corrosion-resistant and water-blocking aluminum sheathed single-conduction heating cable and a preparation method thereof. Background technique [0002] Heating cable is a special form of heating appliance, which converts electrical energy into heat energy through the heating wire inside the cable, and is widely used in electric floor heating heating systems, etc. At present, there are many kinds of heating cables, and they are generally made of non-metallic materials, which makes the insulation sheath of the cable easy to gradually age after long-term use, and the heat dissipation of this kind of cable is relatively slow, the thermal efficiency is low, and the service life is short. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art, and the technical problem to be solved is to provide a corrosion-resistant and water-blo...
