High-performance oil-resistant flame retardant rubber sheath material and preparation method thereof

Abstract

The invention discloses a high-performance oil-resistant flame retardant rubber sheath material which comprises, by weight parts, 75-100 parts of rubber and plastic alloy NVR50, 2-4 parts of vulcanizing agent (DCP), 2-6 parts of accelerator, 4-6 parts of nano zinc oxide, 1-2 parts of stearic acid, 4-6 parts of microcrystalline wax, 3-7 parts of anti-aging agent, 30-40 parts of chloroalcane 52, 68-96 parts of flame retardant and 40-60 parts of carbon black. The invention further discloses a method for preparing the high-performance oil-resistant flame retardant rubber sheath material. The product is resistant to oil, good in flame retardance and low in cost, and the preparation method is simple and facilitates actual operation.

Description

[0002] Along with the rapid development of China's wire and cable industry, the number of new companies has been increasing, the overall technical level of the industry has been greatly improved, and the continuous and rapid growth of China's economy has provided a huge market space for cable products. With China's electric power industry, data communication industry , Urban rail transit industry, coal mining industry, automobile industry, shipbuilding and other industries continue to expand, and the demand for wire and cable will also grow rapidly. People put forward higher and stricter performance requirements for wire and cable sheathing. Cable and cable sheathing In the process of using in high temperature, flammable and corrosive environments, such as in the oil well environment, the oil resistance and high temperature resistance performance cannot meet the requirements, and the rubber surface of the rubber sheath is damaged or even loses its original performance under long-term use, and the aging speed Faster, the existing cable sheath materials are increasingly unable to meet the needs of use, so how to prepare a cable sheath material with good oil resistance, excellent flame retardant performance, low cost, and aging resistance and long service life has become a problem that needs to be solved at present. technical problem
