Abstract

The invention provides an insulation compound halogen-free flame retardant wire and cable which comprises conductors. A shielding layer is arranged on the outer portion of each conductor, and a DMC / SBR / MVQ compound insulation layer is arranged outside each shielding layer. A ceramic silicone rubber layer is arranged on the outer portion of each DMC / SBR / MVQ compound insulation layer, and an expansion layer is arranged on the outer portion of each ceramic silicone rubber layer. Flame retardant glass fiber fillers are filled between the conductors, and flame retardant strips are arranged on the outer portions of the conductors and the flame retardant glass fiber fillers. Expansion strips are arranged on the outer portions of the flame retardant strips, DMC / SBR / MVQ compound protection layers are arranged on the outer portions of the expansion strips, EVA adhesive layers are arranged on the outer portions of the DMC / SBR / MVQ compound protection layers, Teflon / polyimide compound layers are coated on the outer portion of the EVA adhesive layers, and uvioresistant layers are arranged on the outer portions of the Teflon / polyimide compound layers. The invention further provides a manufacturing method of the insulation compound halogen-free flame retardant wire and cable. The insulation compound halogen-free flame retardant wire and cable are provided with multiple insulation layers and flame retardant layers so that it has insulation and flame retardant functions.

Description

technical field [0001] The invention relates to a wire and cable and a preparation method thereof, in particular to an insulating composite halogen-free flame-retardant 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 closely related to various...
