Abstract

The invention discloses a corrosion-resistant flame-retardant cable material comprising the following raw materials by weight: 20-30 parts of low-density polyethylene, 10-20 parts of natural rubber, 8-15 parts of polypropylene, 12 to 24 parts of ethylene-vinyl acetate copolymer, 6 to 9 parts of modified talc powder, 2 to 3 parts of zinc borate, 3 to 7 parts of antimony trioxide, 1-2 parts of calcium stearate, 2 to 4 parts of polyethylene wax, 2 to 4 parts of a coupling agent, 1 to 3 parts of an anti-aging agent and 2 to 4 parts of an antioxidant. The formula of the corrosion-resistant flame-retardant cable material is reasonable, the modified talc powder is added to improve the wear resistance and corrosion resistance of the product, and the modified talc powder synergistically with otherraw materials can significantly improve the flame retardancy of the product.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a corrosion-resistant and flame-retardant cable material and a preparation method thereof. Background technique [0002] In recent years, with the increasing development and popularization of the use of wires and cables in production and life, the demand for wires and cables has increased rapidly, and with the development of the economy, the requirements for its materials have become higher and higher. It requires softness, wear resistance, and durability. low temperature performance. Most of them are flame-retardant cables. As the name suggests, flame-retardant cables refer to the fact that under the specified test conditions, the sample is burned. After the test fire source is removed, the spread of the flame is only within a limited range. A cable that extinguishes itself within a limited time. Its fundamental characteristics are: it may be burned out and cannot o...
