Problems solved by technology

Due to the thermal action of the insulating layer of the wire during normal operation, thermal oxidation and cracking of the insulating material will occur, eventually aging and causing safety accidents such as leakage and fire. Due to the high price of the cable, changing the line midway will cause damage to the building structure. The power supply cables under the road are often overused, and it is imminent to realize the long life of the wires

Abstract

The invention discloses a double-layer co-extrusion insulating LED ultraviolet light cross-linked color low-smoke halogen-free flame-retardant cable material, which is composed of an inner layer insulating material and an outer layer insulating material, and the inner layer insulating material is made of maleic anhydride grafted ethylene- Composition of octene copolymer, polyethylene, ethylene-octene copolymer, flame retardant, flame retardant synergist, antioxidant, metal deactivator, lubricant, photoinitiator, multifunctional crosslinking agent and color masterbatch ; Outer insulating material is composed of maleic anhydride grafted polyethylene, ethylene-vinyl acetate copolymer, syndiotactic 1,2-polybutadiene, flame retardant, flame retardant synergist, antioxidant, lubricant, light Composition of initiator, multifunctional crosslinking agent and color masterbatch. The double-layer co-extruded inner layer insulating material and outer layer insulating material of the present invention pass through LED irradiation equipment after being extruded, and the online crosslinking speed is fast, and all properties of the wire can meet JG / T 441-2014, the mechanical properties and electrical properties of the wire Excellent performance, good flame retardant performance, and its service life can be as long as more than 70 years.

Description

Technical field [0001] The present invention relates to the field of irradiation cross-linking double-layer co-extruded electrical cable, and more particularly to a bilateral co-extrusion insulation LED ultraviolet crosslinking color low-smoke halogen-free flame retardant cable material and a preparation method thereof. Background technique [0002] With the advancement and development of the times, the power and varieties of household appliances are increasing, and the long-loaded operation of the electric wire, the traditional PVC cloth ribs are limited by factors such as technology, process, materials, and use. Long life is only 25 years, while the halogen-free flame retardant used in new single-layer low-halora halogen-free insulation materials is extremely easy to absorb, resulting in a decline in insulation resistance. [0003] The safety of house building wires is related to everyone's life safety. As urban house buildings are rapid, the construction of buildings and build...
