Abstract

The invention discloses a cable filling material resistant to termites and insects. The cable filling material is prepared from, by weight, 3.2-4.4% of sodium silicate, 6-9% of carbon fibers, 17.2-21% of Muscovite, 15-18% of water, 1.36-1.55% of sodium antimonate, 2.1-2.4% of barium-strontium niobate, 2.3-2.6% of liquid butyronitrile, 0.66-0.81% of insect-and-termite-resistant agents and the balance aluminate cement. Compared with a traditional filling material, the cable filling material resistant to the termites and the insects has the advantages of flame retardance, flame resistance, drag resistance, corrosion resistance and insect bite prevention.

Description

technical field [0001] The invention relates to an insect-proof and ant-proof cable filler, which belongs to the field of cable materials. Background technique [0002] The cable core of the cable is composed of multiple insulated wire cores twisted, and there will inevitably be gaps during the cable forming process. If these gaps are not filled with materials, the cable core will be unstable, which will reduce the stress of the cable during use. When the cable is extruded, the cable sheath material will inevitably be embedded in the middle of the cable core, resulting in an increase in the cost of the cable. At the same time, the cable filling material can also avoid the mutual friction between the core wires. [0003] PP rope, polyester tape, tin foil tape, spun yarn, glass fiber silk, cotton thread, and hemp rope are commonly used filling materials. The above-mentioned materials have poor flame-retardant and fire-resistant effects, are easily damaged during the cable dr...
