Abstract

The invention discloses a 150 DEG C irradiation crosslinked low-smoke halogen-free flame-retardant elastomer cable material and a preparation method thereof. The cable material is prepared from the following components: 10-40 parts of ethylene-vinyl acetate rubber EVM; 10 to 40 parts of ethylene propylene diene monomer EPDM; 5 to 20 parts of polyolefin resin; 0-20 parts of a plasticizing system; 20-40 parts of a flame retardant system; 20-40 parts of a smoke abatement system; 1-8 parts of a flame retardant synergistic system; 0.5 to 3 parts of an anti-aging system; 0.2-3 parts of a lubricatingsystem; 0.2 to 1 part of an anti-ultraviolet system; and 0.5-3 parts of a cross-linking sensitization system. After irradiation crosslinking, wires and cables prepared from the cable material have high physical and mechanical properties, excellent electrical insulation properties, chemical medium resistance, flame retardance and heat resistance, and can meet the requirements of cables on long-term working at the temperature of 150 DEG C. The irradiation dose of the cable material is 10-20 Mrad.

Description

technical field

[0001] The invention discloses a 150°C radiation cross-linked low-smoke halogen-free flame-retardant elastomer cable material and a preparation method thereof. Background technique

[0002] With the rapid development of the world economy and the great progress of modern industrial technology, the wire and cable industry is facing more opportunities and challenges. Both German Industry 4.0 and Made in China 2025 have put forward stricter requirements for the cable industry. 150℃ irradiation cross-linked low-smoke halogen-free flame-retardant elastomer cable material has a wide range of market applications in new energy vehicles, high-temperature electrical appliances and other industries. In order to achieve low-smoke effect in the existing technology, a large amount of hydroxide such as Aluminum ATH and magnesium hydroxide MTH, due to a large amount of filling lead to deterioration of mechanical properties.
