Violet cross-linked low-smoke, halogen-free, high flame-retardant EVA wire and cable and preparation method thereof

Abstract

The invention provides a purple-light cross-linked low-smoke, halogen-free, high-flame-retardant EVA wire and cable, which includes a conductor, a shielding layer is arranged outside the conductor, an ultraviolet crosslinking insulating layer is arranged outside the shielding layer, and ceramics are arranged outside the ultraviolet crosslinking insulating layer. Silicone rubber layer, the ceramic silicone rubber layer is provided with an anti-corrosion layer, and the conductors are filled with flame-retardant glass fiber filling ropes. UV cross-linking protective layer, inner UV cross-linking protective layer with armor layer outside, armored layer with outer UV cross-linking protective layer, outer UV cross-linking protective layer with waterproof layer, waterproof layer with SBS outside Rubber layer, the outside of the SBS rubber layer is coated with an anti-ultraviolet layer. The invention also provides a preparation method of the electric wire and cable. The electric wire and cable of the present invention are provided with multiple flame-retardant layers and waterproof layers at the same time, so that the present invention is a purple-light cross-linked low-smoke, halogen-free, high-flame-retardant EVA electric wire and cable.

Description

technical field [0001] The invention relates to a wire and cable and a preparation method thereof, in particular to a purple-light cross-linked low-smoke, halogen-free, high 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 c...
