Abstract

The invention discloses a flame retardant cable sheath formula, which belongs to the technical field of cables, and aims to solve the problem of poor transmission power or signal effect of wires and cables when the temperature exceeds 100°C, and to provide a flame retardant and high temperature resistant cable. Sheath formulation. According to the mass fraction of the present invention, the material components in the formula are as follows: 80-120 parts of PP resin, 50-80 parts of chlorinated polyethylene rubber, 30-50 parts of flame retardant HZR-2, 20-30 parts of polyamide, ethylene ‑20‑30 parts of vinyl acetate copolymer, 5‑10 parts of magnesium oxide, 5‑10 parts of clay, 5‑8 parts of PP‑g‑MAH compatibilizer, 5‑8 parts of precipitated calcium carbonate, 2 parts of nano alumina material ‑4 parts, carbon black 2‑4 parts, paraffin wax 1‑3 parts. The advantages of the present invention are: the cable sheath formed by this formula is more resistant to high temperature, the fire performance is further enhanced, and the cable core in the cable sheath will not be easily melted and damaged in high temperature or fire.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a flame-retardant and high-temperature-resistant cable sheath formula. Background technique [0002] Wire and cable is the carrier of power transmission or information transmission, and is widely used in people's production and life. With the rapid development of my country's national economy and the continuous improvement of people's living standards, the requirement to accelerate the construction of urban special-purpose power grids is becoming increasingly urgent. However, the application occasions of communication cables are complex, and the performance requirements for cables are extremely strict. For some regions or certain environments, the temperature is high and fires are easy to occur. If conventional cables are used for power information transmission, it is easy to damage the cables and cause many unnecessary losses. [0003] The patent for invention with t...
