Purple-light cross-linked low-smoke halogen-free high flame-retardant EVA cable and production method thereof

Abstract

The invention provides a purple-light cross-linked low-smoke halogen-free high flame-retardant EVA cable which comprises conductors. Each conductor is covered with a shield layer, the shield layer is covered with a purple-light cross-linked insulating layer, the purple-light cross-linked insulating layer is covered with a ceramic silicone rubber layer, and the ceramic silicon rubber layer is covered with an anticorrosive layer. Flame-retardant glass fiber filling ropes are filled among the conductors, the conductors and the flame-retardant glass fiber filling ropes are together covered with a flame-retardant tape, the flame-retardant tape is covered with an internal purple-light cross-linked protective layer, the internal purple-light cross-linked protective layer is provided with an armor layer, the armor layer is covered with an external purple-light cross-linked protective layer, the external purple-light cross-linked protective layer is covered with a waterproof layer, the waterproof layer is covered with an SBS rubber layer, and the SBS rubber layer is coated with an ultraviolet-proof layer. The invention further provides a production method of the cable. The purple-light cross-linked low-smoke halogen-free high flame-retardant EVA cable is provided with multiple flame-retardant layers and the waterproof layer.

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...
