Problems solved by technology

[0005] (2) Glass fiber rope: It has a large specific gravity and high hardness, and the fiber will fly with the wind and endanger health. The medium-alkali fiber also contains a large amount of halogen, which does not meet environmental protection requirements;
[0006] (3) Ordinary cotton yarn: the price is too high, the specific gravity is large, there is no flame retardancy, and it will rot after absorbing moisture;

Abstract

The invention relates to a technology of a filling rope and a flame retardant curing solution for manufacturing the filling rope. The filling rope is manufactured by employing the novel flame retardant curing solution through a special technology, and has the advantages of light specific weight, low price, high temperature resistance, flame retardance, non moisture absorption, no halogen, low smoke and accordance with ROHS (Restriction Of Hazardous Substances) standards.

Description

technical field [0001] The invention relates to a process for filling ropes and a flame-retardant and solidified liquid for manufacturing the filling ropes. Background technique [0002] At present, in the production of mining cables, marine cables, flame-retardant cables, fire-resistant cables and other special cables in China, hemp rope, glass fiber rope, asbestos, and ordinary cotton yarn are often used to fill the internal gap of the cable. Because of their advantages and disadvantages, some can withstand high temperatures. However, it has no flame retardancy. Although some have high temperature resistance and flame retardancy, they are not environmentally friendly and cause great harm to the environment and production personnel. The use of this new type of halogen-free nano high temperature resistant cotton yarn filling rope can meet the requirements of high temperature resistance and low smoke at the same time. Halogen-free flame retardant, non-hygroscopic, environment...
