Abstract

The invention discloses a composite environment-friendly high-flame-retardant filling rope for a flame-retardant fire-resistant cable, which comprises a filling rope base material which is roving made of waste polyester cotton, phosphorus-nitrogen water-based flame-retardant powder is dispersed in the base material, a first Mg (OH) 2 flame-retardant adhesive layer is coated outside the base material, a powdery flame-retardant layer is sprayed outside the Mg (OH) 2 flame-retardant adhesive layer, and a second Mg (OH) 2 flame-retardant adhesive layer is coated outside the powdery flame-retardant layer. The powdery flame-retardant layer is coated with a second Mg (OH) 2 flame-retardant adhesive layer, and the second Mg (OH) 2 flame-retardant adhesive layer is coated with a ceramic fireproof layer. The invention further discloses a preparation method of the composite environment-friendly high-flame-retardant filling rope for the flame-retardant and fire-resistant cable. The invention can make up the defects of poor radiation resistance and no flame-retardant and fire-resistant dual performance of the existing like products, and has the advantages of excellent flame-retardant and fire-resistant performance, radiation resistance, environmental protection, high cost performance and the like.

Description

technical field [0001] The invention relates to a composite type environment-friendly high flame-retardant filling rope for flame-retardant and fire-resistant cables and a preparation method thereof, belonging to the technical field of cables. Background technique [0002] Due to the rapid development of the cable industry, the cable industry has become the second largest industry in the machinery industry after the automobile industry. In 2020, its output value has exceeded 150 billion yuan, and flame-retardant cables and fire-resistant cables account for about 50% of it. The demand for flame-retardant and fire-resistant cables in 2020 will reach nearly 500 billion yuan, and it is necessary to use them The annual consumption of less flame-retardant and fire-resistant cable inner core filling rope has reached more than 50,000 tons, and the current annual consumption will still increase at a rate of about 10%. At present, there are many kinds of filling ropes used for flame-...
