Problems solved by technology

[0002] At present, in the cable production process, the corrosion resistance of the cable is very high. Many existing cable materials use inferior raw and auxiliary materials. Although the conventional inspection indicators are qualified, long-term use will cause damage to the copper wire.
Commonly used anti-corrosion additives are easy to corrode copper wire and oxidize and blacken, which seriously affects the performance of cables

Embodiment Construction

[0012] A kind of anti-freeze and fire-resistant cable and cable filler, the raw materials are as follows in parts by weight: 37 parts of siliceous filler, 5.5 parts of fly ash, 2.5 parts of chlorinated paraffin, 2 parts of isomeric alcohol polyoxyethylene ether, rosin foaming agent 1.7 Parts, 1 part of dihydrogen phosphate, 0.5 part of fluorite powder, 2.6 parts of benzyl silicone oil, 0.4 part of silica fume, 0.4 part of nano diatomaceous earth powder, 0.6 part of amino trimethylene phosphoric acid;

[0013] The specific manufacturing method of the cable material is:

[0014] (1) After the siliceous filler, fly ash, silica fume, and fluorite powder are crushed by an ultrafine crusher, 13.5% of the total weight of the above mixture is added to the water, and then the ball mill is used to make raw meal with a particle size of 0.15mm The balls are dried at 160°C for 2.8 hours to obtain ultra-fine aggregates;

[0015] (2) Add rosin foaming agent, dihydrogen phosphate, amino trimethylen...

Abstract

The invention discloses a cable filler for an antifreeze fire-resistant cable. The cable filler comprises the following raw materials in parts by weight: 34-40 parts of a siliceous filler, 5-6 parts of coal ashes, 2-3 parts of chlorinated paraffin, 1.5-2.5 parts of isomeric alcohol ethoxylate, 1.5-1.9 parts of a rosin foaming agent, 0.8-1.2 parts of dihydric phosphate, 0.4-0.6 part of fluorite powder, 2.4-2.8 parts of a polymethylphenyl siloxane fluid, 0.3-0.5 part of silica fume, 0.3-0.5 part of nanometer diatomite powder and 0.4-0.8 part of amino trimethylene phosphonic acid. The cable filler has relatively excellent antifreeze property and fire resistance, does not corrode a copper wire to oxidize and blacken, and is suitable for various complicated environments; and the cost control of the formula is relatively reasonable.

Description

Technical field [0001] The invention relates to the field of cable preparation, in particular to a kind of frost-resistant and fire-resistant cable filler. Background technique [0002] In the current cable production process, the cable corrosion resistance is very demanding. Many existing cable materials use inferior raw and auxiliary materials. Although the conventional testing indicators are qualified, long-term use will cause damage to the copper wire. Commonly used anti-corrosion additives are easy to corrode the copper wire and become black due to oxidation, which seriously affects the problem of cable performance. How to suppress this phenomenon is very important for cable production. Summary of the invention [0003] The purpose of the present invention is a frost-resistant and fire-resistant cable filler, which has better frost resistance and fire resistance, does not corrode copper wires and oxidizes blackening, is suitable for various complex environments, and has a ...
