A waterproof, anti-corrosion, halogen-free and highly flame-retardant EVA wire and cable and its preparation method

Abstract

The invention provides a waterproof anti-corrosion halogen-free high-inflaming-retarding EVA electric wire. The waterproof anti-corrosion halogen-free high-inflaming-retarding EVA electric wire comprises conductors, shielding layers are arranged outside the conductors, inflaming retarding EVA insulation layers are arranged outside the shielding layers, fire retardant layers are arranged outside the inflaming retarding EVA insulation layers, waterproof layers are arranged outside the fire retardant layers, the position between the conductors is filled with an inflaming retarding glass fiber filling rope, an inflaming retarding belt is arranged outside the whole conductors and the inflaming retarding glass fiber filling rope, an internal inflaming-retarding EVA layer is arranged outside the inflaming retarding belt, an armor layer is arranged outside the internal inflaming-retarding EVA layer, an external inflaming-retarding EVA layer is arranged outside the armor layer, a waterproof anti-corrosion layer is arranged outside the external inflaming-retarding EVA layer, a high-temperature-resisting layer is arranged outside the waterproof anti-corrosion layer, and the outer portion of the high-temperature-resisting layer is coated with an ultraviolet-proof layer. The invention further provides a manufacturing method of the electric wire. The electric wire is provided with a plurality of flame retarding layers, meanwhile, the waterproof anti-corrosion layer is arranged, and therefore the waterproof anti-corrosion halogen-free high-inflaming-retarding EVA electric wire can be obtained.

Description

technical field [0001] The invention relates to a wire and cable and a preparation method thereof, in particular to a waterproof, anti-corrosion, halogen-free and highly flame-retardant EVA wire and cable and a preparation method thereof. Background technique [0002] Wire and cable is a wire product used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. As the main carrier of power transmission, wire and cable are widely used in electrical equipment, lighting circuits, household appliances, etc. The quality of wire and cable directly affects the quality of the project and the safety of consumers' lives and property. Although the wire and cable industry is only a supporting industry, it accounts for 1 / 4 of the output value of China's electrical industry. It has a wide variety of products and a wide range of applications, involving industries such as electric power, construction, communications, and manufacturing, and is close...
