Embodiment Construction

[0017] The present invention will be further described below.

[0018] A method for preparing a filler rope for an environmentally friendly flame-retardant wire and cable, comprising the following steps:

[0019] Step 1), prepare raw materials by weight percentage: rock wool 22%-30%, calcium carbonate 60%-70%, penetrant 5%-10%, flame retardant 1%-1.5%;

[0020] Step 2), put the rock wool, calcium carbonate, penetrant, and flame retardant prepared in step 1) into the mixing mixer and stir for 24 hours to obtain the mixing mixture. The speed of the stirring shaft in the mixing mixer is 1500 rpm;

[0021] Step 3), store the stirred mixture obtained in step 2) in the storage tank for 12 hours;

[0022] Step 4), the stirring mixture stored in the storage tank for 12 hours is sent to the mixing mixer for stirring for 4 hours, and the rotating speed of the stirring shaft in the mixing mixer is 1500 rpm;

[0023] Step 5) Send the stirred mixture stirred in step 4) into the trough of...

Abstract

The invention relates to a preparation method of a filling rope for an environment-friendly anti-flaming electric wire. The method comprises the following steps that raw materials are prepared by weight percentage; rock wool, calcium carbonate, a penetrating agent and a flame retardant are put into a mixing stirrer to be stirred to obtain a stirring mixture; the stirring mixture is stored into a storage tank for 12 h and then fed into the mixing stirrer to be stirred for 4 h; the stirring mixture coats a canvas conveyor belt of a coating machine to form a cloth-shaped belt; the cloth-shaped belt is cut into a plurality of cloth-shaped belt bodies; the cloth-shaped belt bodies are retracted into rope-shaped belts to be wound; the multiple wound rope-shaped belts are dried for use; 3-5 rope-shaped belts are selected from the wound and dried rope-shaped belts as needed and stirred with glass fiber filaments through a rope stirring device to form a filling rope for the environment-friendlyanti-flaming electric wire. According to the method, the electric wire is filled with the machined filling rope, the flame retardance of the electric wire is improved, and environment pollution and human body damage caused by dust is avoided in production.

Description

technical field [0001] The invention relates to a preparation method of a filling rope for an environment-friendly flame-retardant electric wire and cable, and belongs to the technical field of processing the filling rope for electric wire and cable. Background technique [0002] Filling rope is an indispensable material in the processing of wires and cables. The filling rope is filled between the sheath and the bare wire of the wire and cable, so that there is no gap between the sheath and the bare wire, and these gaps are filled with filling rope. Finally, the round shape of the sheath is complete, the tensile strength of the wire and cable is increased, and the structure is stable. The existing filling rope has a lot of dust, which affects the environment of wire and cable manufacturing and causes pollution to the environment; meanwhile, the existing filling rope does not have flame retardancy, which affects the flame retardant performance of the wire and cable.
