Abstract

The invention discloses an environment-friendly fireproof low-voltage power flexible cable. The cable sequentially comprises a conductive core, a protective layer and a sheath from inside to outside.The sheath is prepared from the following raw materials in parts by weight: 30-50 parts of chloroprene rubber, 20-30 parts of polyethylene grafted maleic anhydride, 15-20 parts of low-density polyethylene, 1-3 parts of a plasticizer, 2-5 parts of a flame retardant, 1-3 parts of an antioxidant and 1-2 parts of romeite. According to the prepared flexible cable, the chloroprene rubber, the polyethylene grafted maleic anhydride and the low-density polyethylene are adopted as main materials of the sheath, and the plasticizer, the flame retardant and the antioxidant are added, so the toughness of the material is enhanced, and the ageing resistance and the flame retardance of the material are improved; and the strength and the flame retardance of the material are enhanced by adding the romeite.

Description

technical field [0001] The invention belongs to the technical field of fire-resistant cables, and in particular relates to an environment-friendly fireproof low-voltage power flexible cable. Background technique [0002] Neoprene has good physical and mechanical properties, oil resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. Polyethylene grafted maleic anhydride grafts several maleic anhydride molecules on the molecular chain of polyethylene by means of chemical reaction, so that the product not only has good processability and other excellent properties of polyethylene, but also has polar molecules of maleic anhydride reactivity and strong polarity. These two materials are used in the field of cables and can be used to manufacture flexible cables with soft texture and high toughness. However, compared with cables made of single chloroprene rubber, their flame retardancy and fire resistance are poor. [0003] ...
