Problems solved by technology

The aluminum hydroxide or magnesium hydroxide added to this kind of material is an inorganic substance, the surface has not been modified, and the compatibility with the base material of the wire material is poor, and it is easy to seep out of the base material during long-term use, which affects the service life; secondly , the dispersion performance of these unmodified flame retardants in the polymer matrix is ​​not good, which affects the processing fluidity and the comprehensive performance of the wire material

Example Embodiment

[0017] The invention is further described below with reference to the accompanying drawings and specific embodiments.

[0018] See figure 1 The novel B1 wire shown in the figure, including the conductor 1 and the B1 insulating material 2, B1 insulating material 2, and the B1 insulating material 2, so that the material is changed from the line type to a three-dimensional mesh structure. The melting does not melt, with better heat resistance. The conductor 1 is a copper conductor or a tinned copper conductor.

[0019] The B1 insulating material uses a polyolefin composed of ethylene-vinyl acetate copolymer, polyethylene and polyolefin elastomer; simultaneous surface treatment of flame retardants, improves the compatibility of magnesium hydroxide and polymer.

[0020] In a preferred embodiment of the invention, the B1 insulating material is prepared from the following mass percent raw material:

[0021] EVA was 20 serviles, 5 parts of LDPE, 5 copies of modified Mg (OH) 2:56, nitrogen...

Abstract

The invention discloses a novel B1 electric wire, and the wire comprises a conductor and a B1 insulating material wrapping the conductor; the B1 insulating material is subjected to irradiation crosslinking, so the material is changed into a three-dimensional network structure from a linear structure and is changed into a non-fusible structure from a fusible structure, so the novel B1 electric wire has better heat resistance. According to the novel B1 electric wire, the special low-smoke halogen-free flame-retardant polyolefin B1 insulating material is adopted for insulation and is subjected to irradiation crosslinking, excellent electrical insulation performance and mechanical performance can be achieved, the novel B1 electric wire further has excellent flame retardant performance, and no toxic or harmful substance is generated in the product combustion process; meanwhile, the extremely low smoke amount, heat release and corrosivity can obviously reduce the harm in electrical fire disasters.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a novel B1 electric wire. Background technique [0002] At present, flame-retardant wire and cable products in the domestic market generally refer to GB / T 19666-2005 "General Rules for Flame-retardant and Fire-resistant Wire and Cable", GA306.1-2007 "Flame-retardant and Fire-resistant Cable Plastic Insulation Flame-retardant and Fire-resistant Cable Classification and Requirements Part 1 Flame Retardant Cable" and other general standards are implemented, which can meet the general requirements of most engineering sites that will not cause harm to personal safety. In some places where people are relatively dense, according to the latest version of DGJ 08-2048-2016 "Civil Building Electrical Fire Protection Design Regulations" and GB 50016-2018 "Building Design Fire Protection Code" requires super high-rise buildings and a class of high-rise buildings in civil bui...
