The halogen-free low-smoke filling rope is an important raw material in the cable preparation process, and the common flame-retardant filling rope at present has the disadvantages of low flame retardant property of products with good tension and easy stranding, poor tension of products with good flame retardant property and higher requirements on cable process.
Disclosure of Invention
The invention aims to provide a processing technology of a halogen-free low-smoke filling rope for a cable, aiming at the existing problems.
The invention aims to realize the processing technology of the halogen-free low-smoke filling rope for the cable, which is characterized by comprising the following steps of:
step (1), preparing raw materials, wherein the raw materials comprise the following components in percentage by mass: 30-60% of magnesium hydroxide, 10-40% of VAE emulsion and the balance of water; mixing magnesium hydroxide, VAE emulsion and water to obtain slurry;
step (2), coating the slurry obtained in the step (1) on the surface of medium alkali glass fiber cloth through a coating machine, and drying through an oven to obtain a halogen-free low-smoke high-flame-retardance wrapping tape;
step (3) drying and rolling the halogen-free low-smoke high-flame-retardant wrapping tape prepared in the step (2), arranging an edge removing device at the rolling position, removing 4.5-5.5mm wide edge materials at two sides respectively, and collecting the edge materials for later use;
twisting the rim charge obtained in the step (3) into a rope shape to obtain a rope-shaped flame-retardant belt rim charge;
and (5) twisting 3-4 strands of rope-shaped flame-retardant belt edge materials together through a twisting machine to obtain the halogen-free low-smoke filling rope.
And (6) rolling the halogen-free low-smoke filling rope obtained in the step (5).
In the step (2), the temperature in the oven is 170-230 ℃, and the travel speed of the alkali glass fiber cloth coated with the sizing agent in the oven is 7-9 m/min.
The method is advanced and scientific, and convenient to produce, and the invention mainly utilizes the existing halogen-free low-smoke high-flame-retardant tape edge material to manufacture the halogen-free low-smoke filling rope for the cable through a stranding machine. The filling rope is excellent in flame retardant property, good in tension, easy to twist and more suitable for the twisting process of cables. The halogen-free low-smoke high-flame-retardant wrapping tape is prepared by mixing magnesium hydroxide, VAE emulsion and water according to a certain proportion to form slurry, coating the slurry on the surface of medium-alkali glass fiber cloth by a coating machine, and drying by an oven. The halogen-free low-smoke high-flame-retardant belting slurry is prepared from the following components in percentage by mass: 30-60% of magnesium hydroxide, 10-40% of VAE emulsion and 20-40% of water in balance. The halogen-free low-smoke high-flame-retardant wrapping tape is dried and then wound, a trimming device is arranged at the winding position, and the width of each trimming device is 4.5mm-5.5 mm. And finally twisting the leftover materials into a rope shape, and twisting 3-4 strands of twisted leftover materials of the flame-retardant belt together through a stranding machine for rolling to obtain the halogen-free low-smoke filling rope.
The halogen-free low-smoke filling rope for the cable produced by the method has excellent flame retardant property, the oxygen index reaches more than 70, the tension is good, and the rope is easy to wrap. In the processing, the 4.5-5.5mm of rim charge is respectively removed from two sides during slitting, and the rim charge cannot be degraded in the past and can only be buried, so that certain pollution is caused to the environment.
